WNTV Blog for AM Tuesday: Continued Cold Through the End of Meteorological Winter

Snow on Vancouver Island
Thanks to my Aunt Sylvia for these pictures at Qualcom Beach on Vancouver Island. She's an avid golfer, so this is putting a wrench in her golf game. She says that winter has arrived!



Arctic Plunge
Thanks to the University of Maine for the image below, which shows the temperature anomaly for Monday, February 24th and note the big blog of deep blue/purple from the much of North America nosing into the eastern two-thirds of the nation. Interestingly, according to the stats below, even though we were much colder closer to home, the globe as a whole was +0.33F above norm.



Cold Meteorological Winter
Keep in mind that meteorological winter stretches through the three coldest months on average for the northern hemisphere (December, January and February) The image below shows the temperature anomaly for that time frame over the northern hemisphere. Note how cold that time period was for a large chunk of the continent.



Signs of Spring
Thanks to my good friend Stephanie Trindade for this picture out of Las Vegas, NV. I think she's just trying to rub it in, but nice to see some signs of spring no matter where it is located! Hopefully it won't be too long for this to take place it other areas of the country!



SELFIE
Not sure if you've heard of the new catchphrase "Selfie" or not, but this one is great! It's a Squirrel Selfie! Thanks the Zion National Park for this:

More Signs of Spring
Here's an amazing timelapse of storms. It's definitely worth a look!
"Photographer Nicolaus Wegner loves a good storm chase—one of several reasons he produced a new time-lapse video called "Stormscapes.""

Weather Outlook
The weather outlook through PM Thursday shows a little light snow from the midsection of the nation transitioning into a little more rain potential across the southeastern U.S. and more snow for the northeastern part of the U.S. - also note the heavier moisture moving into California at the end of the loop!



Snowfall Potential
Thanks to WeatherBell Analytics for the image below, which shows the GFS snow potential through PM Friday. Other than some light snow chances across the eastern two-thirds of the nation, the biggest threat for heavy snow appears to be in the higher elevations in the western U.S.



Precipitation Outlook
I am most intrigued by the recent outcome in the precipitation department for the western U.S. and especially across California over the next 7 days. Although this rain won't be a drought busting event, it will certainly help! According to NOAA's HPC 7 day precipitation forecast, some areas in California could see +5" by early next week!



Much Needed Rain
Here are the details on the rain chances this week from the NWS in Oxnard, CA:

...Two Storm Systems to Bring the Most Significant Rains of the Winter...

TIMING
Storm #1 - Wednesday afternoon/evening through midday Thursday.
Storm #2 - Friday morning through Saturday

CONFIDENCE
High confidence on timing; moderate on rain amounts. Computer model data has been very consistent with the storm tracks since last Thursday, Feb. 20, therefore, forecasts have not deviated.

MAIN IMPACTS
Storm #1 - This is the weakest storm. No significant impacts outside of the typical slick roadways and minor clogged storm drains are expected Wednesday afternoon through midday Thursday.   
Storm #2 - This is the strongest storm of two. Main impacts will be the potential for heavy downpours in and near thunderstorms. This could lead to mud and debris flows near recent burn scars (Colby, Madison, Springs), and urban flooding of roadways and drainage systems Friday through Saturday. Snow accumulations above 5000 feet on Saturday could lead to road closures or chains required on vehicles. In addition, gusty winds to 50 mph in the mountains could result in reduced visibilities due to fog and/or blowing snow.

AMOUNTS
Storm #1 - 0.25-0.75” in most areas with upwards of 1” for the Santa Ynez and San Gabriel Mountain slopes.
Storm #2 - Widespread 1-2” for coasts and valleys and 2-4” with locally 6” for mountains. Locally heavier rainfall totals can be expected due to the showery nature of the event lingering on Saturday.

SYNOPSIS
Two storm systems in one week will be the first of it’s kind this winter. Storm #1 will be ordinary with minimal impacts expected late Wednesday through midday Thursday. Storm #2 will be much stronger bringing greater impacts Friday through Saturday. We will be monitoring this system closely due to the potential for thunderstorms with heavy rain. Brief downpours could create mud and debris flows near recent burn scars along with urban flood problems due to clogged drainage systems.
It is likely that we will see higher rainfall amounts from these two storms than we have received in total going back to July 1st. Even with the significant rains expected, we would need 5-7 equivalent storms in March and April to get back to a “normal” rainfall season."



Huntington Beach, California
Take a look at this stunning webcam view from Monday afternoon from Huntington Beach, California. This webcam will likely look much different later this week as much needed precipitation heads into the region.

Drought Comparison
It has been extremely dry across the western half of the country for a number of weeks and months. Here's the difference in the drought from February 2013 to February 2014. Note the at this time last year, the biggest drought was across the Plains. While there is still some significant drought in the Plains, the worst has shifted into the western U.S.

WNTV Blog for AM Monday: Cold End to February

Polar Vortex Part Deux?
No not really... Yes, it's cold, but It's actually a piece of the Polar Vortex as explained by the National Weather Service out of New York, NY in a post from January 6th.

"***Please share this information to become more educated on what exactly the polar vortex is and is not*** You may have heard about a "polar vortex" in the news with regards to the cold air currently affecting the United States and soon to hit the Tri-State area. This is NOT a new atmospheric phenomena as a polar vortex ALWAYS exists at the polar regions of earth, but a piece of the main vortex has broken off and is being sent southward by the jet stream. What exactly is the polar vortex, what is it not? Check out this graphic for more information"

See more from the NWS New York HERE:



Alaskan Night Light
Thanks to my very talented and good friend John Thain for this picture out of Palmer, AK. It's a haunting picture of the northern lights at a cemetery, but pretty amazing! Good work, John!



Daytona 500
If you were watching the the Daytona 500 yesterday, you may have noticed the inclement looking skies and the delay due to storms in the area. Take a look at this video from @ChelseaGatesUF from the Dayona 500 yesterday when it was really coming down!

See the video HERE:



Here was the radar just prior to 4pm EST Sunday with a several storms surrounding the Daytona Beach, FL area.



Weather Outlook
No big storm are in sight, but there will be some precipitation. A quick glancing blow of snow will filter into the Midwest from the Northwest, while rain spreads throughout the southeastern U.S.



Precipitation Outlook
Here's NOAA's HPC 7 day precipitation outlook. Note the significant increase in precipitation potential across California. This is great news!



Atmospheric River Acting Up
Keep an eye on that "Atmospheric River" you heard about recently, it's acting up again. Note the plume of brighter colors nearing the West Coast. An increase in moisture is heading your way!



WeatherNation Blog

Read my good friend and colleague (Addison Green)'s blog about the western drough HERE:



Cold Cometh
Take a look at the temperature loop through early next week... it shows a big Arctic surge through the Upper Midwest, which will ripple through the eastern two-thirds of the nation.



Cold Temps Ahead
Here's a look a look at temperatures into early next weekend. Note that highs across the Upper Mississippi Valley look quite cold for the start of Meteorological Spring.



Highs From Normal Saturday
Not only does much of the work week ahead look colder than average, but it looks much colder than average through early next weekend too.



Thanks for checking in and have a great week ahead!

WNTV Blog for AM Sunday: Winter Winds Return

Eagle Cam!
Thanks to the MNDNR for this live camera of a Bald Eagle that is currently sitting on Bald Eagle eggs in a nest! Thanks to the recent snowstorm, the nest is covered in white!.

See the LIVE feed HERE:



Eagle Insight
I had a chance to listen in on KFAN's FAN Outdoors radio show Saturday morning and one of their very knowledgeable guests, Naturalist Stan Tekiela (Twitter: @StanTekiela), talked about the eagles in great details at the end of the first hour. Check out the Podcast from Saturday, February 22nd, 2014 HERE: Not only is Stan an expert on eagles, but he seems to be an outdoor encyclopedia!



Cold Weather Returns
Looks at all the Arctic colors moving back in across the Lower 48. This forecast temperature loop brings us into early next week with the coldest of the cold from the High Plains to the Great Lakes Region. Keep in mind that much of the eastern two-thirds of the nation will be colder than average as head into next week.



Temperature Breakdown
Here's a look at Arctic plunge through the week ahead. Sunday appears to be quite chilly, but look at how cold it will be by Thursday!

Sunday Highs



Sunday Highs From Normal



Thursday Highs



Thursday Highs From Normal



Continued Cold Through Early March
After the big snow and severe weather event we had late last week, temperatures across the eastern two-thirds of the nation look to take a nosedive through the early part of March. Here's the outlook from NOAA's Climate Prediction Center.



Weather Outlook
The weather outlook into early next week looks fairly quiet compared to what we ended last week with. As cold air spreads throughout the eastern two-thirds of the nation, clipper systems will make a comeback. Note the snow spreading into the Midwest from the Northwest. This will likely bring some light snow accumulations along its path.



Snow Potential
Here's the snowfall potential through early next week as our next clipper system crosses the country. Note that snowfall amounts look much heavier in the Northwest than they do in the eastern part of the country. However, note the snow streak over across the Central Plains. Shovelable to Plowable snow is looking more and more likely for some folks there.



Winter Weather Headlines
The National Weather Service has issued winter weather headlines for areas shaded in color below. Mountain snow could near +12" by early next week, while snow in the Central Plains could near 6" by early next week.

Keep an eye on latest watches and warning from the National Weather Service HERE:



Recent Severe Outbreak
According to NOAA's Storm Prediction Center, there were 23 PRELIMINARY tornado reports on Thursday and 5 on Friday. Here are all the reports from that multi-day severe weather outbreak.

Thursday
One of the tornadoes in Missouri caused some injuries as a mobile home was overturned onto a vehicle in the town of Pemiscot, MO. There was also 1 fatality in Ringgold, IA as a strong wind gust blew over a 30ft. conveyor belt



Friday



2014 Tornado Count
According to NOAA Storm Prediction Center, there have been 32 PRELIMINARY tornado reports so far in 2014. According to the 2005 to 2012 average, we are below average to date, which is 91. Note that getting off to a slow start doesn't always mean a quiet year. Take a look at 2011, through February 21st, there had only been 13 tornadoes, but the year ended up with nearly 1900 tornadoes!

Tornado Passing Over Snow Drifts? Extreme Weather Recap - Colder & Quieter Next Week

24" snow on the ground in the Twin Cities. That's the most snow since late January, 1982. Pete Boulay at the Minnesota Climatology Working Group writes:  "24 inches or more has only happened in 8 other years in the Twin Cities, the last time was on January 26, 1982. The record is 38 inches on January 23, 1982... One of the few records the Halloween storm did not break, the deepest snow for the Halloween Blizzard is 23."


On Strike

Remember the movie "Network"? Well I'm having a Howard Beale Moment. "I'm madder than (heck?) and I'm not going to take it any more!"

I can't work under such intolerable conditions. Now I'm a reluctant weather-therapist, trying to help friends, family (and readers) cope with the coldest winter in 35 years. But to no avail. So I'm going on strike and encouraging all Minnesota meteorologists to follow my lead.

Don't show up for work. Maybe a few minutes of dead air will encourage Canada to stop shelling us with subzero artillery.

Enough is enough.

Step away from the Doppler, Paul.

The good news? The glacier in your yard won't grow appreciably into next week - waves of numbing air pushing the storm track well south of Minnesota. The bad news (unless you're into aerobic shivering) is 7 more subzero nights next week, on top of the 45 we've already enjoyed. Hey, if we reach 53 subzero nights it'll be the most since 1978, the 5th most on record.

While we stare out our windows at serious-thermometer-shrinkage the rest of the northern hemisphere is shrugging through a lukewarm winter. According to NOAA January was the 4th warmest, worldwide, on record.

Yes, this too shall pass.

Worst Roads In 30+ Years? The first tip-off was the e-mail headline advising no travel from the State Patrol. The second tip-off was the worst commute of my life yesterday, driving (or trying to drive) from Excelsior to downtown St. Paul - all on side streets. It was like a Mensa-Level Driver's License Final Exam that someone vaguely psychotic thought up, obstacles jumping out at you from every angle. I got here in 1983, and I can't remember roads this bad in 31 years. A rapid drop in temperature Thursday night coincided with the heaviest snow, the "flash-freeze" turning slush near pavement-level into black ice, compaction from car tires above accelerating the icing process. And when it gets this cold the sand and chemicals take much longer to work, if they work at all. Here's a link to the latest Climate Matters, with some of the craziest weather extremes with this last storm: "WeatherNation Chief Meteorologist Paul Douglas talks about the recent severe weather, noting the rarity of tornadoes passing over snowy ground in Illinois. Weather whiplash continues as Blizzard Warnings shared borders with Severe Thunderstorm Warnings in Iowa and the entire storm system drenched the eastern U.S. with heavy rain. Will we have a calmer week ahead?"

Coldest Winters On Record In The Twin Cities. To date we are tied for 9th coldest, the chilliest since 1978-79. Next week's cold wave could push us into the 7th or 8th spot - too early to know, but the Polar Vortex isn't quite done with us yet. Here's an excerpt from The Minnesota DNR: "The winter of 2013-14 has been the coldest in years. So far the average temperature of Meteorological Winter (December-February 19) is 10.0 degrees. If cold weather returns for the rest of February, the winter of 2013-14 would  finish in the top ten coldest winters on record."

The Twin Cities "Winter Misery Index" Reaches 168 (Severe). Snow and cold lovers will be offended; others will nod their head in agreement. Pete Boulay at the MN State Climate Office confirms that this last 10" snowfall tipped us over into a "Severe Winter", as measured by the WMI; here's an explanation from The Minnesota DNR: "The Winter Misery Index (WMI) is an attempt to weigh the relative severity of winters. The index assigns points for daily counts of maximum temperatures 10 degrees or colder and daily minimums of 0 or colder. If the minimum temperature is -20 or colder greater weight is assigned to the value times 8. For snowfall, one inch is assigned a point per calendar day. A four inch snowfall is times 4, and an 8 inch snowfall is times 8. The duration of a winter is noted by the number of days the snow depth is 12 inches or greater. All current measurements are at the Twin Cities International Airport. 

So far as of February 21, 2014 the WMI for the winter of 2013-14 in Twin Cities is 168 points, or in the "severe winter" category. Of course there is quite a bit of winter left. The lowest WMI score was the winter of 2011-2012 with 16 points. The most severe winter is 1916-1917 with 305 WMI points. How many WMI points will this winter score? stay tuned!

How Many Subzero Nights This Winter? We've already enjoyed/endured 45 nights of negative numbers - I see at least another 5-8 over the next 10 days. That could bring our total close to 53, which is what MSP experienced back in 1978 (the 5th most on record). More chilling details from the Minnesota DNR: "As of February 18, there have been 45 minimum temperatures of zero or colder: 13 in December, 20 in January and 12 so far in February. This is the most number of minimums at or below zero in a winter since the winter of 1981-82 when the total was 46. The highest number of at or below zero temperatures in an entire winter is 68 for the winter of 1874-75. The last time there were over 50 minimums of zero or colder was the winter of 1977-78 with 53..."

Holding Pattern Keeps....Holding. Well, give nature some credit for continuity. The pattern has been pretty persistent since early December, and polar air will continue to push south of the Canadian border into late next week. Not as frigid as January or early February, but expect 7 more subzero nights next week, on top of the 45 nights of negative fun we've already enjoyed! The core of the next cold wave arrives by the middle of next week; morning bus stop temperatures Wednesday and Thursday may dip to -20 or -25F. Graph: Weatherspark.

Circle Me Bert! Don't stop circling until 70s show up in that left column ok? Expect a cold first week of March, but the GFS is fairly consistent from run to run, showing 30s returning the second week of March. Kind of sad that so many of us are grateful to see 30s. A measure of how far we've fallen.

Coping With A Long Winter. I was especially grateful for Dr. Mark Seeley's words of wisdom in this week's installment of Minnesota WeatherTalk; here's an excerpt that caught my eye: "...As we face the final stages of this long hard winter in Minnesota, I was inspired to see these words from the writer Victor Hugo:

"laughter is the sun that drives winter from the human face."

This is a winter that we can be thankful for laughter. I know that I saw many more smiles when the temperature finally touched 40 degrees F two days in a row this week in the Twin Cities. At least that gave us a bit of a respite...."

What Cold? Earth Had It's Fourth-Warmest January. No, weather is not climate. The trouble is: we are all hard-wired to react to weather, not the longer, slower (global) climate trends that have so many scientists concerned. Here's an excerpt from Mashable: "...The last January with below average global temperatures occurred in 1976, the bicentennial of the U.S., and the year that the first “Rocky” movie hit theaters. The last below average global temperature for any month was February 1985. According to NOAA, the combined average temperature over global land and ocean surfaces for January was 54.8 degrees Fahrenheit, which was 1.17 degrees Fahrenheit above the 20th century average. Using different analysis methods, NASA also concluded that Alaska had its third-warmest January, and central and southern Africa were record warm for the month as well. China had its second-warmest January on record, and France tied with 1988 and 1936 for its warmest January..."

$40 Billion: Drought Could Be One Of The Most Expensive Disasters In History. Will the rains come in time to help California? The odds are dropping with each passing day; the wet season winds down in March. It would take a (remarkable) amount of rain to replenish dusty topsoil and restore significant water to reservoirs. Here's an excerpt from CBS Sacramento: "California’s drought is so severe, experts say it could have a $40 billion impact on the state’s economy, and they say it could end up being one of the top 10 natural disasters our country has ever seen. Amarel says it’s already forcing farmers to downsize, and it could wipe out some altogether, especially when food prices start going up next year. The ripple effect could cripple the state’s economy, and farmers who remember the drought of 1976 are still bracing for the worst..."

An Improbable Sight. I've been doing this for 40 years, and I can't remember ever seeing something like this. I've read reports of isolated tornadoes over the Rockies, briefly passing over snowfields, a very rare meteorological event. But Thursday this (roping) tornado was photographed about 5 miles away from the photographer. Check out the piles of melting slush in the foreground; looks like half a foot (?) of dirty snow in that one clump. This takes weather whiplash to a new (and ridiculously jaw-dropping) level. Photo courtesy of Dana Cottingham Fricke, from Concord, Illinois.

British Floods - California Drought: A Connection? National Geographic explores the still-controversial theory that rapid warming and ice melt in far northern latitudes may be impacting the configuration of the jet stream; here's an excerpt: "...There is wide scientific consensus that global warming promotes weather extremes in those ways, even if the jury is still out on Francis's hypothesis of an Arctic connection. "We used to say you can't attribute any single event to climate change," says Thomas Peterson of NOAA's National Climatic Data Center. Now, he says, scientists emphasize how climate change is tilting the odds toward extreme events, the way steroids pump up a baseball player: "You know he's hitting 20 percent more home runs, but you don't know if a specific home run is a result of the steroids."

Pacific Nino 3.4 SST Outlook. Over the last few years we've been transitioning from a La Nina cooling phase of the Pacific to an ENSO-neutral phase, which should continue into spring. But models are increasingly hinting at an El Nino event possibly returning by the end of 2014. It's still too early to say, but if you'd like to dig into a little light reading (29 page PDF from NOAA NCEP Climate Prediction Center) give it a shot.

U.S. vs. China: Is This The New Cold War? Financial Times Magazine has a very interesting read here.

Google's Project Tango: A Smart Phone That Sees Your Surroundings. Because my phone isn't already spying on me enough - here's a clip from Gizmag that made me do a triple-take: "Smartphones are, well, smart, but they aren't very interested in their surroundings. This may seem trivial, but when it comes to working with people in what we like to call the “real” world, a mobile device that doesn't understand much outside of its camera view has only limited usefulness. With these limitations in mind, Google’s Project Tango is working on a smartphone that can map its environment in 3D in real time to provide user and device with some common ground..."

Sailing The Seas In A Luxury Submarine. Hey, it's only 175,000 British pounds/night, about $250,000 U.S. A bargain, I'd say, for the very well-off 1% who have more money than sense. The Telegraph has a few details: "Could it be that luxury travellers are tiring of the reliably lavish but occasionally homogenous experiences provided by the world’s best grande dame hotels? Offering truly distinct experiences, an increasing number of entirely unique hotel rooms have opened in recent years. Now, following the unveiling of an underwater hotel room in Zanzibar, the holiday home-rental company Oliver’s Travels is offering its customers the chance to spend the night in a specially adapted leisure submarine..."



Climate Stories....


Play It Again: January Continues Globe's Warm Trend. You'd never know it staring at the thermometer in your back yard, but the planet continues to run a low-grade fever. Here's a clip from Climate Central: "Last month was the fourth-warmest January since recordkeeping began in 1880. It was also the 347th consecutive month with above-average temperatures compared to the 20th century average, which has been fueled in large part by climate change. That streak is one month shy of 29 straight years. Global average temperatures were also among their top 10 warmest for the ninth straight month, according to data released Thursday by the National Oceanic and Atmospheric Administration (NOAA)..."

Old Arctic Ice Is Disappearing And Taking The Rest Of The Ice With It. Slate has the article; here's the introduction: "The National Oceanic and Atmospheric Administration recently released a video that shows compellingly just how bad things are getting at the top of the world. The animation displays Arctic ice over time not just by how much area it covers, but also by age, with white being the oldest ice (nine years or older): It’s not hard to see that over the past few years, the oldest ice has melted away, and over time the ice gets younger. That’s not good: Older ice is thicker and tends to hang around longer; young ice is generally thinner and melts away every summer. That means that the year-round amount of ice is dropping, and dropping rapidly..."
