Sliding Into A Wetter, Warmer Pattern for much of USA



PG-rated 7-Day

"Keep your expectations low - that way you'll never be disappointed."

That certainly applies to weather, especially this spring. Some sensitive readers may need counseling after this forecast. Keep in mind it's a 7-Day Outlook, which is almost guaranteed to change, as new data fuels new computer runs.

Why the pointed pangs of paranoia? Long-range guidance is hinting at rain mixed with some wet snow up north Monday, as a storm tracks south & east of Minnesota. A sure thing? Absolutely not, and even if it does snow a little odds are it won't stick.

That said, April snows are especially annoying. Yes, we may experience a brush with slush early next week.

Unusual? Not really. During a typical April 2" falls on the metro - any snow usually melts within 12-24 hours. Deep breaths.

A stray shower or sprinkle is possible today as a cooler front washes out nearby. A dry Friday gives way to showers, even a clap of thunder Saturday as a cooler front arrives. The ECMWF is printing out about .43" rain for Saturday. Right now I don't expect any heavy snow on Monday, but a light mix is possible north/west of MSP.

The main storm track stays south of town next week. Long range models show 50s, even a shot at 60F by mid-April.

I'd like to be pleasantly surprised. Just once.

Spring Showers. The ECMWF (European) shows about .43" rain on Saturday, which seems reasonable. We dry out Sunday, temperatures aloft just warm enough for light rain Monday - although a little wet snow may mix in west of MSP. Temperatures slowly moderate next week.

Plan B Saturday. Looks like a good day for spring housecleaning, de-cluttering the garage, rearranging your sock drawer, maybe shopping (ugh) or seeing a movie? Saturday looks fairly wet with 4-8 hours of showers, even an isolated T-shower. ECMWF guidance above valid midday Saturday courtesy of WSI.

Slipping Into A Wetter Pattern? It will take months for the drought to ease, but I'm still seeing signs that the pattern is radically different from a year ago, and that may help to favor average or even above average rainfall amounts in the coming months. Any rain won't be able to soak into dusty topsoil until after the frost leaves the ground, which is still 1-2 weeks away for the metro, considerably longer up north.

Trending Wetter. The heaviest rains over the next 5 days will be from Florida into the Carolinas and Virginia's Tidewater, but Saturday's storm may drop some .50"+ rainfall amounts from central Minnesota into Lower Michigan. Some 3-5" rains may spark minor flooding over the Pacific Northwest. QPF map above: NOAA.
 
Atmospheric Tease? At the rate we're going I have no idea when we'll finally warm up, but the GFS is hinting at a spell of 60s, even a few 70s, by mid-April, around April 16-18. One of these days spring will sneak up on us, right?

Nagging Drought Concerns. The Twin Cities metro area has picked up 4.23" of liquid precipitation (rain and melted snow) since January 1, more than half an inch above average. So the trends are encouraging - sadly, little of that moisture will do any good replenishing soil moisture, due to a thick layer of frost in the ground. We're heading into a wetter pattern, but will the storms continue after frost leaves the ground? Let's hope so. Map above showing precipitation during the last week of March courtesy of USDA.

Soil Temperatures. USDA data shows soil temperatures still in the 30s across most of Minnesota. Wheat can't develop until soil temperatures surpass 40F, corn needs consistent soil temperatures above 50F, which is still a few weeks away.

Looking Back At The April 3-4, 1974 Super Outbreak. U.S. Tornadoes has a good summary of the tornado outbreak that shocked the USA in the spring of 1974 (and helped to get me interested in meteorology). Here's an excerpt: "The “Super Outbreak of April 3-4, 1974” occurred across portions of the Midwest, Lower Mississippi Valley, and Southeast.  In what was the worst tornado outbreak of the 20th century, there were 148 tornadoes over the course of just 18 hours, almost half of which were classified as significant/strong at F2 strength or higher. Many comparisons have been made between this outbreak and the April 25-28, 2011 outbreak which featured 358 tornadoes.  Although the more recent outbreak featured many more tornadoes, they occurred over a longer time period in an age of better tornado detection, and the worst was confined to a smaller area compared to April 3-4, 1974..."

The 12 Cell Phones That Changed Our World Forever. Wired.com takes a good, long walk down memory lane. Remember the "brick phone"? Oh, I was so proud to have one of these tethered to my car. What was I thinking? "Motorola engineer Martin Cooper made telecommunications history when he placed the first cellphone call 40 years ago. And who did he call, you ask? His rivals at Bell Labs, of course. Oh snap! Still, it took another decade for the mobile phone to reach the masses, because Motorola didn’t make the DynaTAC available until March 1983. And in an example of just how quaint the tech business was back then, Motorola had a press event 10 years before the phone was on sale. Which brings us to April 3, 1973, when the company that eventually brought us the Razr and Droid introduced the mobile phone. Forty years later, we’re still dropping calls like bad habits and struggling to get a signal inside a supermarket. Not that it matters, because we rarely use our phones to make phone calls. Instead, they’re a gateway to our digital lives, a means of doing everything from sending texts to updating our status to posting photos and listening to music. Thousands of phones have come and gone, and most of them seem to run on Android. But the number of handsets that could be called truly groundbreaking is surprisingly small. Here they are. Yeah, yeah, we’ve probably missed your favorite. And you’ll probably tell us about it in a comment typed on your phone....

Airline Lavs Shrink To Fit More Seats. Great news! Now you'll have to go on a diet just to use the bathrooms at 30,000 feet. Here's an excerpt from The Wall Street Journal: "Airplane space-squeezers have been back in the lavatory – not a typo – shrinking the space that airplane bathrooms take up. My colleague Susan Carey reports on a ground-breaking coach-cabin lavatory built by B/E Aerospace that won over Boeing Co. and airlines because it packs a loo into a little space and allows for a few more coach seats on planes. Delta Air Lines Inc. will be among the first customers to get the petite potty, and those 737-900s will have four additional seats because of smaller lavs..."


Deer Paul. Yes, those are deer in my front yard - a lot of deer, foraging for food, eating our plants. I'm as ready for spring as everyone else - trust me on that one.


Climate Stories....


Clouds Helped Enhance Greenland's Record Melting. Here's an excerpt of a very interesting story at Climate Central: "When scientists saw melting across a whopping 97 percent of Greenland’s icy surface last summer, they were quick to note that such an event is rare, but not unprecedented. The last time it happened was in 1889, so while manmade global warming is clearly involved it isn’t necessarily the entire story. A new new report in Nature on Wednesday has now helped flesh out the explanation: data from Summit Station, at the frozen island’s highest point, 10,551 feet above sea level, show that unusually warm temperatures in the region were enhanced by a blanket of low-level clouds that trapped extra heat from the Sun..."

Economist Warns of "Radical" Climate Change, Millions At Risk. Alarmist climate hype? I sure hope so. AFP has the story - here's the intro: "The author of an influential 2006 study on climate change warned Tuesday that the world could be headed toward warming even more catastrophic than expected but he voiced hope for political action. Nicholas Stern, the British former chief economist for the World Bank, said that both emissions of greenhouse gas and the effects of climate change were taking place faster than he forecast seven years ago. Without changes to emission trends, the planet has roughly a 50 percent chance that temperatures will soar to five degrees Celsius (nine degrees Fahrenheit) above pre-industrial averages in a century, he said. "We haven't been above five degrees Centigrade on this planet for about 30 million years. So you can see that this is radical change way outside human experience," Stern said in an address at the International Monetary Fund..." (Image: NASA).

"The Whole Story Of Climate" Book Throws Climate Change A Curveball. Huffington Post has the story - here's an excerpt: "...In a fascinating new book -- The Whole Story of Climate: What Science Reveals About the Nature of Endless Change by Prometheus Books -- Peters explains how the media and politicians have distorted the facts on climate change, have come to the wrong conclusions on its causes, and have failed to prescribe real antidotes to the runaway greenhouse gases that are building up in the earth's atmosphere.

The Hype of Sustainability
Early on, Ms. Peters tears away at the misguided belief that if we develop sustainable technologies and change human behavior it will prevent the globe from "flipping" into the next Ice Age. It will not. We have delayed the latter some ticks of the geological clock, but we can't stop climate change, because that is what the earth has been doing for millions of years -- long before people walked upright..."

Sliding Into a Wetter Pattern (cause for flooding concerns Upper Midwest)



Spring Paradox

I'm just the messenger, but I get emotional about weather, just like everyone else. I want it to warm up, I want it to rain (hard) and ease our long-term drought. I just don't want it to happen in the next few weeks. The reason? River flooding.

NOAA data shows 4-7" of liquid water (snow water equivalent) locked in the snow pack over west central and northwestern Minnesota. Details below.

Trying to predict flooding is a science within a science; as much art as science, to be honest. Hydrologists factor the depth of ground frost, water content in the snow, the rate of expected warming and any rain (which accelerates snow melt) into their models.

The risk still appears greatest for the Red River, but residents living along the Mississippi and Minnesota Rivers shouldn't let their guard down just yet.

None of us will take spring for granted this year. It is spring, right? Temperatures top 50F today; it may be warm & unstable enough for thunder Saturday. Skies dry on Sunday - more significant heavy rain events shaping up for Tuesday, again Thursday of next week; maybe 1" of liquid water (mixed with wet snow up north).

Old Man Winter is like the annoying uncle who just doesn't know when to go home.
 
Whispers of Spring. No tulips or daffodils blooming anytime soon, but highs should top 50 today and Thursday; ECMWF model guidance still hinting at upper 50s, even low 60s Saturday ahead of the next frontal passage. Showers, possible thunder Saturday, with the main event coming late Tuesday into Wednesday of next week, probably warm enough for rain. We can only hope.
 
Shifting Gears. We're heading into a wetter pattern, a storm in the upper atmosphere over the Desert Southwest forecast to eject a series of storms northeastward across the Plains into the Upper Midwest next week. A large north-south temperature contrast should set the stage for potentially significant rains, possibly even mixing with wet snow from North Dakota into northern Minnesota next week.

The Art Of River Flood Forecasting. I have a lot of empathy for the hydrologists (river forecasters) at the National Weather Service in Chanhassen. In spite of computer simulations predicting when and where a river will crest is still as much art as science, as I explain in today's edition of Climate Matters: "Springtime can mean sandbagging and water woes for folks who live along rivers and streams. If temperatures can gradually warm up, it can help ease flood concerns. But there are many more factors to consider when trying to forecast flood potential. Meteorologist Paul Douglas explains."

USA Snow Cover. Snow is on the ground over roughly 17% of the USA (lower 48 states), down from 47% of the USA back on March 3. Map above: NOAA.

Snow Water Equivalent. There's still a fair amount of liquid water trapped in the snow pack over west central and northwestern Minnesota, as much as 4-6" of water, according to NOAA estimates. The potential for river flooding, especially Red River Valley, will depend on a multitude of factors, including how quickly frost leaves the ground, how rapidly temperatures warm, and whether warm fronts are accompanied by significant rain, which would accelerate snow melt and raise the odds of flooding.

Current Flooding. NOAA data shows some major flooding in the Devil's Lake, North Dakota area, moderate flooding on the Duck River near Green Bay, minor flooding near Rochester and across southern Wisconsin. With warming temperatures and a wetter pattern seemingly imminent I expect river and stream flooding to be on the increase in the coming weeks.

Coldest March Since 2002. Not exactly record-smashing, but a departure from our trend of milder Marches and earlier springs since roughly 1998. Details from the Twin Cities office of the National Weather Service: "March of 2013 will be remembered for one thing, cold. After having a March in 2012 that had temperatures that belonged more in April, this March went the other direction as persistent cold air resulted in the Twin Cities, St. Cloud, and Eau Claire all having their coldest March since 2002. March also continued the trend started in February with Minnesota and Wisconsin being stuck in a bit more of a snowy and wet pattern, with the monthly snowfall total at St. Cloud putting them in as the 9th snowiest March of all time with Eau Claire experiencing its 5th snowiest March on record. The big storm this March occurred on the 4th and 5th, when a system dumped over 10" of snow along the Minnesota and Wisconsin border. There was a second snow storm that hit areas from Albert Lea through Eau Claire the hardest on the 15th. Certainly by the time the first significant that was observed the last few days of the month, it was a welcome occurrence!

In the end, tempertatures across the region for March of 2013 were 5 to 10 degrees below normal, snowfall was 6-12+ inches above normal (outside of southwest Minnesota), while melted precipitation was nearly 1" above normal (outside southwest Minnesota). Again, the southwest part of the state managed to watch the heaviest precipitation stay north or east of them, and as a result, southwest Minnesota ended up being the only part of the region to see below normal snowfall and precipitation."

FEMA Frustrated By Drop In North Dakota Flood Policies. Not an encouraging trend, considering that major flooding is expected across the Red River Valley within the next few weeks. The Bismarck Tribune has the story; here's the intro: "As North Dakota faces another possible major flood this spring, federal officials are frustrated by the number of people in the state who lack insurance for such a disaster. Along the Red River and its tributaries in flood-prone Fargo and Cass County, the number of insurance policies dropped by more than 40 percent from 2011-12, FEMA officials said. Residents there have battled flooding for five of the last seven years. “It’s an amazing phenomenon how people can go through these things, then drop their flood insurance and try to buy it back in time,” FEMA spokesman Dave Kyner said. “I guess that’s one of the most frustrating things for us here.” Flood policies in all of North Dakota declined 32 percent, which coincided with a dry year throughout the state. Policies must be in effect for 30 days for flood damage to be covered..."

Torrential Rains Flood Argentina's Capital Killing 5. Amazing amounts of rain at Buenos Aires, as reported by Associated Press and The Washington Post: "Torrential rains in Argentina’s capital have triggered flooding responsible for at least five deaths. A record 6.1 inches (155 millimeters) of rain fell in just two hours in Buenos Aires on Tuesday. That’s equal to all of normal rainfall for April. The storm caused power outages, flooded subway lines and turned the streets into rivers..."

Arctic Warming Blamed For Last Year's Warmth And This Year's Chill. Omaha.com has a good explanation of how changes in the Arctic may be having a domino effect at lower latitudes; here's an excerpt: "...The Arctic is warming at two to three times the rate of the rest of the globe. As it warms, there's less contrast between the temperature of Arctic air and the atmosphere farther south. As a result, the jet stream weakens. A strong jet stream tends to flow fairly directly, west to east. A weakened jet meanders at a slower pace, looping north and south.

The consequences:

» A weakened jet is more likely to form atmospheric blocks, which tend to create “stuck” weather patterns.

» The meandering allows Arctic air to plunge southward or warm air to surge northward.

» Combined, these two factors stack the odds in favor of prolonged hot or cold spells and contribute to stalled storm systems
..."

Tornadoes And Sequesters. Will the "sequester" and budget cuts impact the quality of severe storm and tornado forecasting? WJLA-TV's Bob Ryan takes a look - here's an excerpt: "...This week NOAA, also the parent agency for the National Weather Service (NWS), announced a hiring freeze at a time when its vacancy rate is already around 10%. I understand that this number is near 20% for the Washington DC area NWS Office. At this point, pause and consider public safety. As we enter the severe weather/tornado seasons, the Sequester has forced the hand of our NOAA management and possibly jeopardized the American public's safety, stifled scientific capacity, obliterated morale within NOAA/NWS, and dampened hopes for the next generation of federal meteorological workforce. Beyond safety, we have increasingly clear evidence that weather is important to our economy (see commentary by me and Nancy Colleton on the "next Commerce Secretary" at http://www.huffingtonpost.com/nancy-colleton/the-next-secretary-commerce_b_2807671.html). Now to be clear, I know, personally, the senior level managers at NOAA/NWS very well. I know they will do everything within their power to adjust and mitigate impact. This commentary is really not about them.."

6, 7-Day Storm Forecasts As Good As Closer Ones A Decade Ago. Forecasting hurricane intensity is still terribly difficult, but NHC is doing an increasingly good job with the predicted "forecast cone" showing the expected path of hurricanes. Meteorologist Eliot Kleinberg reports at The Palm Beach Post: "Six- and seven-day National Hurricane Center forecasts conducted “in house” in 2012 had about the same margin of error that four- and five-day forecasts a decade ago, center senior specialist Dan Brown told a Thursday session of this week’s National Hurricane Conference. Errors were 240 nautical miles at Day Six and 300 nautical miles at Day Seven, which is “actually a pretty good forecast,” Brown said. But he noted that positions that far out are of limited value; even a 240-mile error margin on either side of a storm is a lot of ocean. The longer-range forecasts are part of a  suite of products the hurricane center is working on, Brown and hurricane center colleagues said. Among them: a graphic showing the potential arrival time of tropical storm force winds — “we heard loud and clear that this was a product that everybody wanted,” specialist Robbie Berg said — and a graphic showing predicted wind speeds over certain areas..."
 
The Urban Heat Island Could Be Attracting Bugs. It's no secret cities and suburbs can be 5-15F warmer than outlying suburbs and farmland, and this has numerous consequences, including the potential to attract new and exotic bugs. Here's an excerpt from The Atlantic Cities: "...The study is kind of a groundbreaking effort in the research niche where insects, cities and weather intersect. As the scientists note:
Urbanization of an area changes the species that dwell in it. Previous studies have analyzed these effects in terms of loss of resources or changes to habitat, but this is the first research to focus on the effects of "heat islands" created in cities. Meineke explains that, "Urban warming can lead to higher insect pest abundance, a result of pest acclimation or adaptation to higher temperatures."
The study concludes that since current urban warming is similar in magnitude to the higher temperatures predicted by global warming in the next fifty years, their results may indicate potential changes in pest abundance as natural forests also grow warmer..."

Place Your Bets. This is from page 80 of my bootleg copy of the 2013 Old Farmer's Almanac, kept under lock and key in my desk drawer. Cool and dry? I hope not, for the sake of our perpetual drought. I'm betting on considerably wetter than last year, but also cooler and less humid, with more severe T-storms than we experienced in 2012.

Can We Patent Life? Here's an excerpt of an intriguing, if troubling story from The New Yorker: "...As they do, we edge closer to one of modern science’s central goals: an era of personalized medicine, in which an individual’s treatment for scores of illnesses could be tailored to his specific genetic composition. That, of course, assumes that we own our own genes. And yet, nearly twenty per cent of the genome—more than four thousand genes—are already covered by at least one U.S. patent. These include genes for Alzheimer’s disease, colon cancer, asthma, and two in particular—BRCA1 and BRCA2—that are highly associated with breast cancer. Myriad Genetics, a company that specializes in molecular diagnostics, holds the rights to those two genes. Anyone conducting an experiment on them without a license can be sued for infringement of patent rights. This means that Myriad can decide what research is carried out on those genes, who can do that research, and how much any resulting therapy or diagnostic test will cost. The same holds true for other genes and for any pharmaceutical company, scientist, or university that holds patents similar to those held by Myriad....

 
America Is Watching More TV Than Ever, Just Not On TV. The trends are consistent - we're increasingly tapping the Internet (and mobile devices) to get our TV fix. Here's an excerpt from Quartz: "It seems like only December 2010 that Americans admitted to spending as much time on the internet as they did in front of their televisions. Less than three years later, one-third of America’s internet users—and more than 80% of the population is an internet user—say they would consider ditching TVs altogether, according to a new report by market research firm eMarketer. That may not sound like a huge proportion but by next year, more than half of American internet users will be watching movies and television shows over the internet..."

What's In A Nickname? The Origin Of All 30 MLB Team Names. Here's an excerpt of a fascinating read from Mental Floss: "With the Major League Baseball season getting underway, here's the breakdown of how the league's 30 teams got their names...

Minnesota Twins: Minneapolis and St. Paul, which are separated by the Mississippi River and collectively known as the Twin Cities, argued for years over where an expansion team in Minnesota, should one arrive, would call home. When the Washington Senators moved to Minneapolis in 1961, club officials settled on Twins as the team nickname and unveiled an emblem showing two baseball players with hands clasped in front of a huge baseball..."
 

Samoa Air First To Charge Passengers By Weight. Let's hope this trend doesn't spread to U.S. carriers. And no, I don't think this is an April Fool's Day joke. Details from ABC News: "If it's an April Fools' Day joke, it's an awfully elaborate one. If not, Samoa Air has become the first airline in the world to do what was previously unthinkable: Charge passengers by weight. Yes, you get weighed. By a stranger. At the airport. Not that the idea hasn't been floated -- several times -- in the past. In fact, ABC News reported just last week a Norwegian economist was the latest to float the idea of an airline "fat tax." The Samoa Air homepage reads "We at Samoa Air are keeping airfares fair, by charging our passengers only for what they weigh. You are the master of your Air'fair', you decide how much (or little) your ticket will cost..."






Climate Stories....


Public Alarm Over Climate Change Grows. Here's a clip from The Yale Daily News: "Yale researchers have found that Americans are growing increasingly alarmed about climate change. On March 15 Anthony Leiserowitz, director of the Yale Project on Climate Change Communication, appeared on national television saying that Americans are ready for the government to “end the silence” on climate change. He cited a study called “Global Warming’s Six Americas,” published on March 6 by researchers from the YPCC and the George Mason Center for Climate Change Communication, which showed that the number of Americans alarmed about climate change has increased from 10 percent in 2010 to 16 percent in 2012. Researchers from Yale and George Mason are now questioning whether public alarm about climate change is connected to weather extremities such as February’s 38-inch blizzard. “There is something fundamentally different in the way Americans are engaging with the issue of climate change at this moment,” Leiserowitz said. “Our political leaders have been silent about the issue and the media has been very quiet. Now we are beginning to talk about it again...”

Climate Denialism Has Peaked. Now What Are We Going To Do? Here's an excerpt of an important essay at EcoEquity: "...The denial of the challenge, on the other hand, always came ready-made.  As Francis Bacon said so long ago, “what a man would rather were true, he more readily believes.”  And we really did want to believe that ours was still a boundless world.  The alternative – an honest reckoning – was just too challenging.  For one thing, there was no obvious way to reconcile the Earth’s finitude with the relentless expansion of the capitalist market.  And as long as we believed in a world without limits, there was no need to see that economic stratification would again become a fatal issue.  Sure, our world was bitterly riven between haves and have-nots, but this problem, too, would fade in time.  With enough growth – the universal balm – redistribution would never be necessary.  In time, every man would be a king. The denial had many cheerleaders.  The chemical-company flacks who derided Rachel Carson as a “hysterical woman” couldn’t have known that they were pioneering a massive trend.  Also, and of course, big money always has plenty of mouthpieces.  But it’s no secret that, during the 20th Century, the “engineering of consent” reached new levels of sophistication.  The composed image of benign scientific competence became one of its favorite tools, and somewhere along the way tobacco-industry science became a founding prototype of anti-environmental denialism.  On this front, I’m happy to say that the long and instructive history of today’s denialist pseudo-science has already been expertly deconstructed.[3]  Given this, I can safely focus on the new world, the post-Sandy world of manifest climatic disruption in which the denialists have lost any residual aura of scientific legitimacy, and have ceased to be a decisive political force.  A world in which climate denialism is increasingly seen, and increasingly ridiculed, as the jibbering of trolls..."

Trillions Of Dollars Are Pumped Into Our Fossil Fuel Addiction Every Year. How are the most profitable companies on Earth still getting subsidies? Skeptical Science has the story; here's an excerpt: "A new report from the International Monetary Fund (IMF) estimates that overall global fossil fuel subsidies amount to about $1.9 trillion annually.  As large as this number sounds, it's actually an underestimate for many reasons.  The IMF report lists several of these reasons, including the fact that it's simply impossible to obtain data for all fossil fuel subsidies in all countries.  However, the biggest contributor to the conservative dollar figure is related to the social cost of carbon. The social cost of carbon is an estimate of the direct effects of carbon emissions on the economy, and takes into consideration such factors as net agricultural productivity loss, human health effects, property damages from sea level rise, and changes in ecosystem services.  It's the economic damage caused by CO2 via climate change.  The IMF report uses an average US government agency value of $25 per tonne of CO2 emissions; however, there is substantial evidence and research suggesting the value should be much higher.  Dave Roberts provides some references in his post on the report, and we go into detail on the subject here..."

Outlook: Warmer & Wetter East of Rockies by Next Week

 
GR8TFULL

Driving back from a speech to farmers in Lake Crystal last week I saw a license plate that made me think. GR8TFULL. Most of us are so preoccupied with everything that's wrong with our lives; it's helpful to remember what's going right.

Yes, our delayed spring is annoying, but persistent chill has slowed snow melt & delayed severe storm season. 2012's jaw-dropping warmth was accompanied by a severe drought. The current pattern is a radical departure from last year's dry, Pacific wind. There's growing evidence of a sustained flow from the Gulf of Mexico, pulling enough moisture north to gradually ease our drought by late spring.
That's the hope & expectation.

Wind chill in early April is a major annoyance, but it may bode well for a year of more normal temperatures and rainfall patterns across the Upper Midwest.

Winds ease today; 50F will feel great tomorrow. Try to ignore snowy rumors for late week. The European (ECMWF) model hints at 40s to near 50F Saturday with a few showers. Steadier, heavier rain arrives late Sunday into Monday. How this rain impacts area rivers is still unclear, but it pays to be perpetually paranoid.

Live near a stream or river? Stay alert.
 
Warming Trend. ECMWF data suggests 50 by Wednesday and Thursday, even a slight shot at 60F Saturday before a round of showers and T-showers move through. Heavier, steadier rain is possible late Sunday into Monday, the wettest day in sight.
 
Sliding Into A Wet Pattern. I see three rain events over the next week: showers and possible thunder Saturday, much heavier rain late Sunday into midday Monday (potentially mixed with wet snow over central Minnesota), then another chance of steady/heavy rain a week from Thursday.
 
Storm Machine. By Monday upper level winds (500mb winds at 18,000 feet) will be blowing from the southwest, pulling Gulf moisture northward. As long as a storm in the upper atmosphere is stuck over the southwestern USA the potential for significant rain events over the Plains and Upper Midwest will be high. My concern: enough rain to (rapidly) melt snow up north, which would accelerate snow melt and heighten the risk of river flooding, especially Red River Valley. It's too early to say, but I could definitely envision a rapidly escalating river flood risk up north by mid and late April, just looking at how the pattern is setting up.



Idaho Duststorm Speeds Up Snowmelt: "Nobody On Our Staff Has Ever Witnessed Anything Similar". Here's an excerpt of a bizarre story courtesy of Think Progress: "...Another day, another amplifying feedback of Dust-Bowlification. The Idaho Statesman reports: A dust storm that covered the mountains accelerated runoff at the end of winter, exposing scientists to a strange event. Scientists say the storm on March 6 caused unprecedented melting. The dust-on-snow show came during five hours of wind that averaged 34 miles per hour and gusted up to 57 mph on ridgelines at the Reynolds Creek Experimental Watershed in the northern Owyhee Mountains. Hydrologists at the U.S. Department of Agriculture research area then observed accelerated melting from March 10 to March 16, when a new dusting of snow covered the layer of dirty snow. “Nobody on our staff has ever witnessed anything similar,” said research hydrologist Adam Winstral..."

No April Fool's Day Joke. The National Weather Service in Marquette, Michigan released this photo Monday, showing their weather instruments buried in 3-5 foot snow drifts. No, spring is nowhere in sight over the U.P. of Michigan.

World's Top Supercomputer From '09 Is Obsolete, Will Be Dismantled. Here's an excerpt of a fascinating, if a bit unsettling, article from Ars Technica: "Five years ago, an IBM-built supercomputer designed to model the decay of the US nuclear weapons arsenal was clocked at speeds no computer in the history of Earth had ever reached. At more than one quadrillion floating point operations per second (that's a million billion, or a "petaflop"), the aptly named Roadrunner was so far ahead of the competition that it earned the #1 slot on the Top 500 supercomputer list in June 2008, November 2008, and one last time in June 2009. Today, that computer has been declared obsolete and it's being taken offline. Based at the US Department of Energy's Los Alamos National Laboratory in New Mexico, Roadrunner will be studied for a while and then ultimately dismantled. While the computer is still one of the 22 fastest in the world, it isn't energy-efficient enough to make the power bill worth it..."

Climate Stories....


Recent Warming Is Still Unprecedented In Speed, Scale and Cause. Here's an excerpt from Think Progress: "Earlier this month, we reported on a new study by Marcott et al. in Science: Recent Warming Is ‘Amazing And Atypical’ And Poised To Destroy Stable Climate That Enabled Civilization. It was the source of most of the data in this popular, jaw-dropping graph.

Now Real Climate has posted a summary and FAQ by Shaun Marcott and colleagues, which I’ll excerpt below. As the real climate scientists at RC note:
Our view is that the results of the paper will stand the test of time, particularly regarding the small global temperature variations in the Holocene. If anything, early Holocene warmth might be overestimated in this study.
The main, stunning conclusion we can draw from the paper is that the rate of warming since 1900 is 50 times greater than the rate of cooling in the previous 5000 years, which undermines the whole notion of adaptation..."

Changing Seasons. Here's an excerpt of a story from physicist Mark Boslough at Huffington Post: "...Scientists and meteorologists have voiced growing concerns that the winter season is disappearing across much of the northern hemisphere. Dr. Jeff Masters put it bluntly, "Mother Nature has fast-forwarded past spring and gone straight to summer over the Midwest." Now a group of scientists who see this trend as unstoppable have proposed changing the way we define seasons. Mark Boslough, a New Mexico physicist, explained, "We have chosen to define seasons in a very arbitrary way. Seasons are an artifact of human creation and it's time for an update." Boslough pointed out that astronomy went through a similar controversial redefinition in 2006, when the International Astronomical Union redefined the meaning of the word "planet" and removed Pluto from the list..."

Global Warming Expands Antarctic Sea Ice. It's counterintuitive, yes, but warming around Antarctic is actually increasing the amount of sea ice, as reported by Nature; here's an excerpt: "...“The paradox is that global warming leads to more cooling and more sea ice around Antarctica,” says Richard Bintanja, a climate researcher at the Royal Netherlands Meteorological Institute in Utrecht. Bintanja and his colleagues show that enhanced melting of the Antarctic ice sheet — which is losing mass at a rate of 250 gigatonnes yearly — has probably been the main factor behind the small but statistically significant sea-ice expansion in the region..."

Americans Want Climate Change Preparation, Don't Want To Pay For It. Environmental Leader has the story - here's a snippet: "An overwhelming majority of Americans want to prepare to minimize likely damage caused by global warming-induced sea-level rise and storms, but most citizens want people whose properties and businesses are located in hazard areas – not the government – to foot the bill for such measures, according to a survey conducted by the Stanford Woods Institute for the Environment and the Center for Ocean Solutions. Some 82 percent of those surveyed said that people and organizations should prepare for climate change in advance, rather than simply deal with the damage after it happens. Among the most popular policy solutions identified: strengthening building codes for how to build new structures along the coast to minimize damage, favored by 62 percent of respondents, and preventing new buildings from being built near the coast, which was supported by 51 percent...."

What Deniers Of Climate Change Must Deny. Here's an excerpt of a Doug Craig post at Redding.com: "...There are numerous facts, truths and realities climate change deniers must deny in order to cling to their delusions and remain active members in the science denial club. Here is another one.

2) The history of climate science. We have nearly 200 years of climate science starting with Joseph Fourier who first considered "the possibility that the Earth's atmosphere might act as an insulator of some kind" and first proposed what is now known as the greenhouse effect.

Over the years we have had Tyndall, Arrhenius, Callendar, Plass, Suess, Revelle, Keeling, Charney, Lovelock, Hansen, Broecker, Oreskes and Schneider, to name but a tiny few of the important figures who have made significant contributions to climate science. Most of us will leave little record of lasting import that we were here or did anything of significance for humanity. Unlike these giants of science. Climate change deniers must deny the very history of the science that has brought us to this moment. In fact, the less they know, the better. If they actually studied and understood climate science, they would not be deniers..."

Global Warming: The Earth is Hurting. Here's the intro to an Op-Ed at Pakistan's Express Herald: "We have an amazing planet, the only one in the universe with a perfect ecosystem. It has enough food and water, amazing species and a nature which has created the perfect balance for long-term sustenance. Human intervention and abuse is unfortunately destroying this fine balance and if we do not take corrective action soon, we may not leave an inhabitable planet for future generations. Why is Earth hurting? The reason has nothing to do with the fact that humans have passed the 7 billion mark and another 2 billion will be added by 2050; God’s grand design can sustain human population far beyond this number.  The reason has more to do with how we treat Earth, how callous we are when it comes to controlling pollution, deforestation and ozone depletion..."
