A Weekend of Extremes (pinpointing potential for record warmth, flooding, plowable snow and isolated tornadoes)



Crazy Contradictions

2013 was another year of head-shaking weather. Yes, the atmosphere has always been fickle, capable of wild extremes, but there's evidence of more volatility in the system.
It was the Year of All or Nothing.

Minnesota's drought eased by late spring, then returned suddenly with a late summer "flash drought". Heavy snow fell in early May and the Arrowhead saw a rare August frost. SPC reported 11 Minnesota tornadoes, a third of what we normally see. But the June 21 "Solstice Storm" produced 80 mph straight-line winds that toppled thousands of trees.

2013 was the quietest year for hurricanes in the Atlantic since 1982, but the Pacific was very active. Typhoon Haiyan was one of the most powerful storms ever observed, leaving over 6,000 dead in the Philippines.

The return of Fresh Air sets off an inch or two of fluff early today, another coating to an inch Saturday night, as a reinforcing clipper arrives. No prolonged thaws are brewing; 20F Christmas Day, maybe 30F the following Saturday, December 28.

Until the pattern shifts and steering winds blow from New Mexico it'll be tough getting any big storms into Minnesota.

At least snow lovers are having a better winter than usual - and we'll all get to enjoy a very white Christmas.

2013: All Or Nothing For Tornadoes And Hurricanes. In today's edition of Climate Matters we recap last year's Christmas Day tornado outbreak, a reminder that December is still prime time for tornadoes along the Gulf Coast and Florida. It was a very quiet year for hurricanes (in the Atlantic), and the USA saw fewer tornadoes than average, but from Moore, Oklahoma to Washington, Illinois (on November 17) there were large and deadly exceptions to that rule. The day with the most tornadoes: November 17 (74 touched down). I haven't seen that before: "WeatherNationTV Chief Meteorologist Paul Douglas goes over the severe weather set up on Saturday and shows that December tornadoes aren't out of the realm of possibility. How has this year stacked up to others weather wise. After seeing the damage to Washington, IL, we're actually BELOW average for the number of tornadoes on the year. And the Atlantic hurricane season wasn't nearly as active as years past, just how weak was it and why?"

A (Mostly Cold) Temperature Roller Coaster. ECMWF guidance above shows a chilly stretch into much of Christmas week, the coldest weather coming next Monday, again Thursday, before temperatures possibly rebound the end of next week. I still think the "Euro" is overestimating the cold a bit, but it probably has the right general idea of the timing of these next cold slaps. Graphic: Weatherspark.

Big Extremes. By Saturday subzero air pushes into the Northern Plains, while 60s and 70s surge up the East Coast, setting the stage for a significant storm: snow for the Midwest and Great Lakes, potential flooding over the Ohio Valley, and even a severe storm and tornado outbreak from the Mid South to the Gulf Coast. 2-meter NAM temperatures going out 84 hours courtesy of NOAA and Ham Weather.

84 Hour Snow Potential. Amounts don't look quite as impressive across the Midwest, but plowable snows are still posssible from near Wichita and Kansas City to Peoria, Rockford, Madison and Milwaukee. Chicago may still pick up a couple inches, but the heaviest snow band will probably stay north/west of The Windy City. NAM guidance: NOAA and Ham Weather.

Flood Risk. A plume of moisture flowing out of the Gulf of Mexico will fuel an intensifying storm, and NOAA guidance suggests some 3-5" rainfall amounts from Little Rock and Louisville to Indianapolis and Cleveland, capable of urban and small stream flooding. QPF map: NOAA.

Saturday Severe Storm Potential. SPC has much of the Mid South and Gulf Coast under a "slight risk" of severe storms. Keep an eye on this - if the threat level goes to "moderate" the risk of large, potentially violent tornadoes will be significant. Map: NOAA and Ham Weather.

Current Watches, Warnings And Advisories. From Winter Storm Watches and Advisories to Flood Watches, there will be plenty of weather to track from now thru Sunday. Click here to see the latest NOAA information, courtesy of Ham Weather.

No Snow In Siberia? Locals Marvel - And Worry - At The "Snow Shortage". Much of the northern USA has snow on the ground, but portions of Siberia are experiencing an abnormally mild, largely snow-free December, to date. Here's a clip that caught my eye from The Siberian Times: "...The startling pictures from Krasnoyarsk show an almost total absence of snow yet as every school child around the world knows, snow is what Siberia is all about. No more, it seems. The images of the River Yenisei with ducks splashing in the water, and grass in the parks, could be from autumn rather than deep in the winter in a city where December temperatures have gone as low as minus 47C, and the daily mean in minus 13C at this time of year, with plenty of snow on the ground.  As in many areas of Siberia this winter, the thermometer is reluctant to plummet to customary bone-chilling temperatures. Last night when we checked outside, it was a mere minus 3C. Day time temperatures lately have been warmer. As mother-of-two Anastasia said from Krasnoyarsk: 'I'm reading a book to my children and I hear the tapping of the rain in my ear. Rain? Rain??? Rain in the middle of December? In Siberia?...."

Cold Bias Into Early 2014. The latest NAEFS model, courtesy of Environment Canada, shows warmer weather for much of Alaska and western Canada, but a cold bias for much of central and eastern Canada and a fairly large chunk of the Lower 48. Any January Thaw will be fleeting this year - we may have to wait a few more weeks to really thaw out.

Average Winter Snowfall. I thought this was a timely graphic to show, displaying average winter snowfall from the Upper Mississippi Valley into the Great Lakes and Ohio Valley. Of course the weather is never average; we careen from one extreme to the next. Since 1998 winters have trended milder, with considerable volatility. Some winters see little snow, while others have been well above average in the snowfall department. Graphic: Midwest Regional Climate Center.

Drought Outlook. NOAA's latest drought outlook through the end of March shows a potential for persistent drought over parts of central and southern Minnesota and southwest Wisconsin into Q1 of 2014.

Alerts Broadcaster Briefing: Issued Thursday, December 19, 2013.

* Potential for glaze ice event Friday from Missouri and Iowa into southern Wisconsin. Flash flood risk Middle Mississippi Valley.
* Heavier band of snow sets up from near Kansas City to Quad Cities and Madison Sunday and Sunday night - probably enough to shovel and plow. Chicago and Detroit will probably miss the worst of this late weekend storm.
* Series of very powerful storms spinning up in the North Atlantic, capable of wind damage and power outages across U.K., Ireland and Scotland - greatest risk coming Thursday of next week.

Current Watches & Advisories. NOAA has issued Freezing Rain Advisories from Kansas City to Des Moines and Madison from late tonight into Friday as rain falls on surfaces colder than 32F. Some glaze icing is possible over this part of the Midwest tomorrow. Chicago should not be affected. Map: NOAA.

Sunday Snow Event. A second storm tracking across the center of the U.S. will drop a relatively narrow carpet of significant snow, from near Wichita and Overland Park to Des Moines, Quad Cities, Rockford, Madison and Milwaukee. Chicago may see a few inches of slush by Sunday night, but the brunt of the accumulating snow tracks north and west of The Windy City. NAM guidance: Ham Weather.

High-Res Solution. As much as 10" of snow is predicted for parts of Kansas, closer to 5-6" southern and eastern Iowa into far northwest Illinois and the southeastern third of Wisconsin, including Madison, Milwaukee and Green Bay. Lower Michigan will pick up as much as 8-10", but the snow bands should stay north/west of Lansing, Ann Arbor and Detroit.

Snowfall Potential. I suspect GFS amounts (above) are running a little high, but they have the right idea, especially over Kansas, Missouri and Wisconsin. Chicago is still something of a meteorological wild card; I'm expecting a couple inches of slush late Sunday, but right now it appears the heaviest amounts will stay north and west of Chicago, closer to Rockford, Janesville, Madison and Milwaukee.

Another Wild Week for Britain. Our internal Alerts Broadcaster models show a very significant risk of wind-damage, power outages and some level of urban and river flooding, especially over the United Kingdom, as a parade of intense, even violent storms surge across the North Atlantic into the British Isles. It's early, but right now it appears the worst of the storms may arrive a week from today, with wind gusts possibly reaching hurricane force. Graphic: Ham Weather.

Next Thursday, December 26. The GFS solution shows an extremely powerful storm over Wales, a tight pressure gradient whipping up sustained winds of 30-50 mph with gusts approaching hurricane force over much of the British Isles one week from today. We'll keep an eye on it, but facilities in the U.K., Ireland and Scotland will be impacted by a series of extreme storms. (Graphic: WeatherBell).

Summary: Midwestern operations will be impacted by rain, ice and (Sunday) snow, as the next surge of cold air pushes east - while eastern cities as far north as New York City and Philadelphia enjoy 60s on Saturday, 70s from Washington D.C. to Charlotte and Raleigh, highly unusual for the third week of December. We're tracking a series of unusually intense storms across the North Atlantic and North Sea, capable of disrupting operations, especially United Kingdom, over the next 7-10 days.

An Explosion In Slow Motion: How 2013 Blew Apart Our Notions Of Privacy. Here's an excerpt of an excellent and vaguely terrifying story at Gigaom: "2013 was an extraordinary year for those of us who are interested in privacy and data protection. What was previously seen as the domain of paranoid nitpickers has exploded into the public consciousness, shaking international ties and making many people re-evaluate how they live their lives online. But it would be a mistake to see 2013 purely in terms of Edward Snowden and his revelations. Indeed, months before the former NSA contractor downloaded what he could and fled to Hong Kong, the year began as it meant to go on: by demonstrating the power and dangerous potential of our increasingly open, plugged-in nature..."

Identity Theft: America's Fastest-Growing Crime Barely Even Registers As "Crime" For Most People. The Atlantic Cities takes a look at the resources going into hacking YOU. Here's an excerpt: "...Property and violent crime affect us where we live and work, and we expect local government to do something about them. But even though these categories seem comprehensive, neither one includes identity theft. Considering identity theft now costs Americans nearly twice as much as property crime, that's an odd omission. In a recent report, the U.S. Bureau of Justice Statistics found that total losses attributed to identity theft in 2012 were $24.6 billion, compared to $13.9 billion for property crimes..."

Of Course Washington Is Broken: It Was Designed To Be. Here's a sobering look at what Washington D.C. has become, and what's needed to fix the perpetual gridlock, courtesy of Medium.com: "For a group of people dependent on public support for its professional survival, Congress has done a truly remarkable job of alienating the American public. Over the past four decades, the polling firm Gallup has regularly asked U.S. adults about their level of confidence in various institutions. In June of this year, Congress hit rock bottom: Just 10 percent of respondents expressed a “great deal” or “quite a lot” of confidence in the legislative branch of government. That’s down from 42 percent in 1973—a year blighted by an international oil crisis and marked by the country’s withdrawal from Vietnam.."

8 1/2 Things That Went Right In 2013. Bloomberg BusinessWeek has the upside to another crazy year; here's the introduction: "It was a year of cronuts and pretzel buns, green eggs and ham, of Syria and Mali and the East China Sea, of Edward Snowden and Pope Francis, Xi Jinping and Kim Jong Un. Jeff Bezos showed off a package-delivering drone. Twitter (TWTR) tweeted its own IPO announcement. Stocks went up, housing revived, unemployment fell, and banks got fined. American Airlines (AAL) and US Airways merged, and a solar-powered airplane hopscotched across the U.S. We can’t discern much of a pattern here. But in the spirit of the holidays, here’s a look on the bright side—a list of the things that went right in 2013, sometimes unexpectedly. It is short, admittedly, but sweet. May 2014 be better yet..."

“Those who have the privilege to know have the duty to act.” - Albert Einstein

Poll: Americans See Impact Of Global Warming. Here's a clip from a story at USA Today: "Most Americans say global warming is serious and want the United States to address it, but their support for government regulations has fallen in recent years, says a poll out Friday conducted for USA TODAY. Three of five say global warming is a very serious global problem, and two of three say it will hurt future generations either a lot or a great deal if nothing is done to reduce it, according to the poll of 801 U.S. adults done in conjunction with Stanford University and Resources for the Future, a non-partisan research group, which funded the research...."

Most Companies Still Releasing Unsustainable Amounts Of CO2 - Study. Reuters has the findings; here's the introduction to the story: "The majority of large global corporations that have reported their annual greenhouse gas emissions for several years now are still releasing more carbon dioxide than they should, a new study published on Wednesday showed. And most companies scrutinized in the study are still not using science-based thresholds to set emissions targets and to drive actions to reduce their carbon footprint. Coordinated by U.S.-based Climate Counts, an organization that measures the role corporations play on climate, the report tried to analyze emissions of 100 companies against science-based targets that seek to limit rising temperature to two degrees Celsius..."

White House To Get Aggressive On Climate Change? Here's a clip from The Washington Post: "...Environmentalists are looking at this today with a sense of optimism, since they have been pushing the White House for years to get aggressive on climate change with executive action, the only avenue available, given the reality of today’s Congress. But what would it look like if Podesta actually gets the White House to go through with this in a comprehensive way? One place to start for an answer is a report on what a president can accomplish with executive action that was written by one…John Podesta, before he joined the White House. It suggests an array of executive actions that a President can take on climate change..."

Why Environmentalists Should Hope Nuclear Power Sticks Around. Here's an excerpt of an Op-Ed at The Washington Post: "...Some environmentalists cheer the closing of nuclear plants, even though it makes the anti-carbon effort tougher, and they argue that the country should put all of the planet’s eggs into the renewables basket. The pro-nuclear crowd predicts that a new wave of innovative technologies will make constructing new nuclear plants much more attractive, technically and economically. The country — and particularly environmentalists — should hope the pro-nuclear side is right; a renaissance in nuclear technology could offer the country a source of reliable, carbon-free electricity with safer designs than those of decades ago, all of which would be particularly helpful if renewables never burst out of their niche end of the market..."

Climate And Economic Models - Birds Of A Different Feather. University of St. Thomas climate scientist John Abraham describes the differences in this story at The Guardian; here's an excerpt: "...We can see the two big weaknesses with business models. First, they do not follow any universal conservation equations. There is no analogy for mass, momentum, and energy in a business model. Second, behavior of economies in the past may not be a proper indicator of the future. Should we expect the U.S. economic recovery from the great recession be anything like the recovery from the Great Depression? Can stimulus or austerity success or failure be predicted by past stimulus or austerity cases? The answer is, we just don't know...."

Climate Change Threatens Retirement Savings. Do you have a 401K or a few mutual funds? At some point you may want to check and see how many fossil fuel companies are in the investment mix, according to this article at Scientific American - here's an excerpt: "The Asset Owners Disclosure Project asked 1,000 of the world's largest asset owners what they were doing to guard against the possibility that their investments in fossil fuels could, in future, become worthless. Together, the owners manage more than $70 trillion. The Project found that only 27 of the 458 investment funds replying to its request are addressing climate risk at what it considers a responsible level. Only five of the 458 achieved the AODP's top score, AAA. An additional 22 rated A or above. Only these groups, says the Project, "will survive a carbon crash in any kind of good shape..."

Rising Sea Levels Torment Norfolk, VA, And Coastal U.S. Here's an excerpt from a story and video provided by USA Today: "...Flooding has become so common in this city, where water is the lifeblood, that residents talk about it in the supermarket. Home to the world's largest naval base, Norfolk sits on flat land — much of it filled-in marsh that's now at sea level and sinking. Add to that the sea-level rise from global warming, and the city faces what it deems a $1 billion-plus problem. As the 10th part of its year-long series on climate change, USA TODAY traveled to Virginia's picturesque Tidewater region — bound by creeks, rivers and the Chesapeake Bay — to look at how rising sea levels are affecting America's coastal communities, where more than a third of its people and wealth reside..."

Documenting The Swift Change Wrought By Global Warming. Here's a clip from a photo essay at Yale Environment 360: "For 25 years, photographer Peter Essick has traveled the world for National Geographic magazine, with many of his recent assignments focusing on the causes and consequences of climate change. In a Yale Environment 360 photo essay, we present a gallery of images Essick took while on assignment in Antarctica, Greenland, and other far-flung locales. The photographer says that what most struck him was the dedication of the scientists who have committed themselves to documenting the effects of global warming..."

Global Warming As Haiku. Chris Mooney has the story at Mother Jones; here's an excerpt: "Recently at the annual American Geophysical Union meeting in San Francisco, a number of climate researchers and communications specialists sounded off about the problems involved in conveying climate science information to the public. Naomi Oreskes, the Harvard science historian, noted one of the many challenges: There's a huge gap between how grave the climate issue actually is, and how clinical and detached climate scientists seem to sound when they discuss it. "Our tone doesn't match our words," Oreskes said. As a result, climate communications often lack emotional authenticity..."
