"Blizz-nado" (extreme weather whiplash - another late week snowstorm Upper Midwest & Great Lakes?)


I'd like to lock Mother Nature in my basement and throw away the key. March came in like a polar bear and went out like a (rabid) mountain lion, with blizzard conditions over the Red River Valley yesterday, but that wasn't the most unusual feature of yesterday's weather map.

In 40 years of tracking the weather I have NEVER seen a tornado warning and a blizzard warning in effect (simultaneously) for the same county. That happened yesterday in Yellow Medicine county; tornadoes moving at 40 mph causing structural damage near Saint Leo - the county under a blizzard warning for high winds and snow expected to move in Monday night. A new level of weather-whiplash. A new level of bizarre.

Whispers of the Polar Vortex return today as cold exhaust shakes the trees outside your window - a coating of slush possible in the metro; a few inches of snow for Brainerd. But we all realize that spring in Minnesota is always two steps forward, one step back.

A clumsy atmospheric waltz.

No more 60s in sight anytime soon, in fact heavy jackets linger into late week with a few days in the 30s and low 40s. It's premature to toss around inches, but there may be enough cold air in place for a slushy snow event by Friday. But even if it does snow a high sun angle guarantees rapid melting, with 40s returning next week, even a shot at 50F.

If anyone asks the average high reaches 65F in the Twin Cities by the end of April. Extended models show a cool bias. We won't be boating anytime soon.

Longer term an El Nino is brewing; warmer Pacific water which often correlates with milder winters here. That's more of a prayer than a forecast by the way. But we go from one extreme to the next.
Maybe we'll catch a break.

Minor Structural Damage. Abraham Grant snapped this photo near Saint Leo, showing EF-0 damage to outbuildings - no reports of injuries from yesterday's freakish tornadoes in Yellow Medicine County.

* NOAA SPC confiirmed 3 tornadoes as of late last night. Details here.

Taking Weather Whiplash to a New Extreme. Tornado warnings issued for a county under a Blizzard Warning? True, blizzard conditions weren't expected until Monday night, and convection whipped up in the "dry slot", a surge of warm, dry air that pushed into southwest Minnesota, resulting in highs in the 70s, a sharp temperature gradient and subsequent low-level wind shear that spun up a couple of small tornadoes. (Map: Earth Networks).

"Hey Paul, I have a question. Have you ever seen a confirmed tornado (Warning) in the same place where a Blizzard Warning is also in effect? Hard to believe my eyes right now. Then again in Wisconsin yesterday there was elevated fire danger in the same areas where rivers were flooding. What could possibly be ahead??? Cue the locust."

Kent Smith
Eden Prairie

Short answer? No.

Who's Your Mamma? Sorry - I've been standing too close to the Doppler. No locust showing up (yet), but Mike Gaddow in Prior Lake captured a great shot of cumulonimbus mammatus clouds as thunderrshowers pushed across the metro Monday evening, "pouches" of rain and hail illuminated by the setting sun.

Spring Is In No Great Hurry. This probably won't come as much of a surprise, but there's every indication we'll limp into spring this year. The southern USA is warming up nicely, but a series of cold intrusions sweeping out of Canada will result in a sharp north-south temperature gradient capable of whipping up a series of storms: rain and snow. The best chance of precipitation comes Thursday into Friday, possibly a rain/snow mix ending as a few inches of slushy snow Friday. Graphic: Weatherspark.

Too Early To Panic (Much). Again, I tend to go with "persistence", which is a fancy way of saying go with the flow, don't deviate from the current pattern and trends. Spring is taking it's sweet time, with only a few tantalizing glimpses of real warmth. I'm not buying a major snowfall for Friday (yet) - I want to see a few more computer models and see if the solutions are consistent. But there's certainly a potential for a "few inches" of slushy snow Thursday night into late Friday. GFS data shows the best chance of a hearty pile of snow south/east of the Twin Cities. Too early to say with confidence, but we'll keep an eye on it. Feeling lucky?

A Reason To Keep On Going. After showing the GFS model solution it would be cruel and unusual not to leave you with a few ragged scraps of hope. Here it is, courtesy of NOAA's CFS (Climate Forecast System) model, showing highs consistently in the 60s or milder after about April 23. My confidence level is low in anything that far out, but let's pretend this might actually happen. Graphic: Ham Weather.

A 1,720 Foot High Tsunami? I thought it was a typo at first, but apparently not. Good grief. I'm feeling better about being near the center of the North American continent. Here's an excerpt from an eye-opening account at Quartz: "...Calamity struck at 10pm on July 9, 1958, when a 8.0-Richter-scale earthquake rammed the Alaskan coast up and northward. That impact shook free between 40 million and 60 million cubic yards (30.6 million and 46 million cubic meters) of rock and ice that rimmed the Lituya basin, dumping it 3,000 feet into the bay below. The 1,720-foot monster that reared up as a result shot through the bay at 100 miles per hour (161 kilometers per hour), as Susan Casey details in her bookThe Wave: In Pursuit of the Rogues, Freaks and Giants of the Ocean..."

Higher Probability Of El Nino By Summer of 2014. The threshold is .5C, and we should reach that in the Pacific as early as May or June. For a little light reading and more than you ever wanted to know about a brewing El Nino and ENSO in general, check out this 29 page PDF from NOAA NCEP.

Update On California Drought. Residents of the western USA may be praying for a moderate to severe El Nino warming phase of Pacific Ocean water, which correlates with more frequent storms for California and a more active southern branch of the jet stream. Here's a good summary of the deepening drought from Peter Gleick at

4.8 Magnitude Quake Hits Yellowstone. The tremor was reported on Sunday in an area riddled with earthquake faults - more details from (Map: Google).

Parallel Parking In The Arctic Circle. If you missed Thomas Friedman's latest Op-Ed in The New York Times it's definitely worth a read - with a son in the Navy I found this especially fascinating. Here's an excerpt: "...More important, you learn how crucial acoustics are when operating deep under ice with no vision and no GPS satellite to guide you. Or, as the New Mexico’s captain, Todd Moore, 40, put it: It’s like every day “engaging in a knife fight in a dark room: the only thing you can do is go after what you hear.” You can’t see the adversary. You can’t see the ice keels, but you can hear enemy subs, surface ships, whales, calving icebergs, schools of fish and bounce sound waves off them with sonar to measure distances..."

People Can Predict The IQ Of Men, But Not Women, By Looking At Their Face. Deep down you always knew this, right? Here's an excerpt from "New research published in PLoS One has found that a man’s facial characteristics contain some clues about his intelligence. Surprisingly, the same can’t be said for women’s facial traits. And the particular male facial characteristics linked with intelligence are a mystery..."

How You Know If You're A Serious Techno-Geek. At least this new wearable camcorder doesn't look too dorky. Details from Gizmag: "Panasonic has unveiled the world's first 4K 30/25p wearable camcorder, the HX-A500. Following in the dua-body footsteps of the HX-A100, the camera part of the new 4K-toting device can be worn on the head sans helmet thanks to head mount, while the main body – which now includes an LCD monitor for checking shots on the go – sits in an armband worn by the user..."

Here's an excerpt of real news you can use from Swimmingly: "Today is Major League Baseball’s Opening Day, the start of the 2014 season. That means it’s also the time of year for America’s second-favorite pastime: the scoreboard marriage proposal. To step up your engagement game, we reached out to all 30 MLB teams to find out the cost of putting a ring (World Series or otherwise) on it at each stadium..."

Land Of Mega-Extremes. While temperatures flirted with 70 across southwestern Minnesota, and tornadoes touched down not far from Canby, residents of Duluth and International Falls were enjoying 30s with 24" of snow still on the ground in both cities. Good grief.

Climate Stories...
* "The Hellish Monotony of 25 Years of IPCC Climate Change Warnings." Graham Readfern has the story at The Guardian.

Panel's Warning On Climate Risk: Worst Is Yet To Come. Justin Gillis has a good summary of the latest IPCC report in The New York Times; here's an excerpt: "...The scientists emphasized that climate change is not just some problem of the distant future, but is happening now. For instance, in much of the American West, mountain snowpack is declining, threatening water supplies for the region, the scientists reported. And the snow that does fall is melting earlier in the year, which means there is less meltwater to ease the parched summers. In Alaska, the collapse of sea ice is allowing huge waves to strike the coast, causing erosion so rapid that it is already forcing entire communities to relocate. “Now we are at the point where there is so much information, so much evidence, that we can no longer plead ignorance,” said Michel Jarraud, secretary general of the World Meteorological Organization..."

MIT Scientist Responds On Disaster Costs And Climate Change. FiveThirtyEight has an article from hurricane expert Kerry Emanuel from MIT; here's an excerpt: "...The increasing normalized trends in the U.S. were evident in convective storms, winter storms, flooding events and high temperature-related losses, and were almost statistically significant for hurricanes at the conventional 95 percent confidence level.3 In view of data like this, it’s very hard to accept Pielke’s confident assertion that “[n]o matter what President Obama and British Prime Minister David Cameron say, recent costly disasters are not part of a trend driven by climate change...”

Wake Up To The Reality Of Climate Change. Here's an excerpt of an Op-Ed at CNN that caught my eye, from former (Republican) Governor of New Mexico and U.S. Energy Secretary Bill Richardson: "...We are now witnessing how it is changing our world: The past winter was the eighth-warmest on record. For 348 consecutive months -- 29 years -- global temperatures have been above average. The latest IPCC report finds that impacts from climate change are "widespread and consequential" and they are being felt on every continent and in our oceans. The world last year experienced 41 weather-related disasters that caused damages totaling at least $1 billion. Over the past decade, the western United States experienced seven times more large-scale wildfires than it did in the 1970s. Climate change has made it much more likely that we will suffer severe droughts like the one that recently swept across Texas and my home state of New Mexico..."

North America: Shifting Water. New Scientist examines how climate change will impact specific regions around the world. Here's an excerpt focused on North America: "...Rain and storms will move northwards, flooding areas north of New York and leaving southern areas short of water. Mexicans will have to do everything they can to preserve water and escape the heat. Adapting to water deficits is not too hard: the key is increased efficiency. But extra flooding is more problematic, with total costs expected to increase tenfold this century. The US has the capacity to adapt, but is struggling with misinformation and a lack of political will..." (Photo: ThinkStock).

Food And Water Shortages May Prove Major Risks of Climate Change. Scientific American has more on the implications of continued warming; here's a clip: "...In that light, climate change becomes a risk management proposition, particularly given the uncertainty about exactly how bad impacts might become and when. The worst risks include sea level rise for small islands and coasts, flooding, the breakdown of infrastructure in the face of extreme weather, loss livelihoods forfarmers and fishers, food insecurity and heat-wave deaths.

By the 2030s most of the changes in crop yields are negative," says Andy Challinor, University of Leeds climate researcher, author on the paper, and on the new IPCC report, too. "The second half of the century is when the negative impact in yields becomes more common." The researchers found this by comparing results from almost 100 independent studies—more than double the number used in the IPCC's fourth assessment—that measured the impact of higher temperatures on three of the globe's primary staple crops: maize, wheat, and rice..."

WNTV Blog: Another 'Springy' Storm with Rain and Heavy Snow

Active Weekend in the Northeast
This is what a months worth of rain looks like in less than 24 hours. Thanks to @jacobdog97 for the picture below out of Westerly, RI.

Heavy Northeast Snow
While some folks were dealing with heavy rain, others were dealing with heavy snow. Take a look at this picture from Rochester, NY! Thanks to Donny Rodgers who said that there was no snow on Saturday and then this on Sunday!

Sunday Temperatures
It was nice to see temperatures in the middle part of the country showing more spring-like signs again. The image below was the temperature outlook at 4pm CDT Sunday and note how far north the 60s and 70s were!

Winter 2013-2014 Perspective
Sunday temperatures across parts of the Midwest were some of the warmest readings we've seen since late last year. The 2013-2014 winter was quite a bit colder than average from Canada to the eastern two-thirds of the nation, but NOAA sheds light on how our cold winter compared to the entire globe.

See more from NASA's Earth Observatory HERE:

"For many residents of North America, the winter of 2013-14 has felt like one of the coldest in many years. Waves of Arctic air brought extended periods of cold weather and above-average snowfall to the middle and eastern portions of the United States and Canada. Seven Midwestern states had one of their top-ten coldest winters, and the Great Lakes were chilled until they reached nearly 91 percent ice cover. Even portions of Mexico and Central America were cooler than normal.

But human memory is not a scientific measure, and long-term perspective tends to get lost in everyday conversation and news coverage. The winter of 2013-14 followed two winters that were significantly warmer than the norm, which likely made this season feel worse than it was. Researchers at the U.S. National Climatic Data Center (NCDC) reported that the average temperature of the contiguous U.S. for the winter was just 0.4° Celsius (31.3° Fahrenheit), about 1°F below average."

"The map below puts the North American winter in wider context. On a global scale, land temperatures for the December through February period were actually the tenth warmest in the modern record, according to NCDC, 0.87°C (1.57°F) above the 20th century average."

"Far eastern Asia, particularly China and eastern Russia, were significantly warmer than normal. In Europe, Austria and The Netherlands observed the second warmest winters in their records, and Switzerland its third warmest. With temperatures as much as 5°C above normal, spring crops and plants began sprouting several weeks early across much of Europe. And in the southern summer, the extended heat waves in Australia and Argentina stand out."

Recent Earthquakes
It seems as if there have been a string of earthquakes over the recent weeks and this weekend was another fairly active weekend. There were two quakes in the western part of the country; a 5.1 magnitude quake near Los Angeles, CA on Saturday and a 4.8 magnitude quake in Yellowstone National Park!

Weather Outlook
As our latest storm system exits the Northeast another storm system takes shape across the Midwest. The next storm in the Midwest will be responsible for heavy snow and blizzard conditions across the Dakotas and parts of Minnesota.

Precipitation Outlook

According to NOAA's HPC the 5 day precipitation forecast suggests heavier blobs of moisture across the western part of the country and again through the middle part of the country. The end of March/early part of April looks quite active across much of the nation, except for much of the Desert Southwest.

U.S. Snowfall Potential

Here's the snowfall potential from AM Sunday through PM Tuesday

Record Wet March in Seattle, WA
Despite the very nice picture below from my good friend Aaron Theis out of Seattle, WA last Monday, March 24th, Seattle has seen it's wettest March in recorded history!

Take a look at some of the stats below from the National Weather Service out of Seattle, WA

WNTV Blog: Active End to April, More Snow for Upper Mississippi Valley

Lake Superior Ice Fishing
Now this seems a little strange to see ice anglers still at it on Lake Superior in Late March! In fact, I can't remember the last time I saw this! Thanks to my good friend Jeremy Frazier for the picture below from Duluth, MN who is enjoying a weekend with family!

Lake Superior Ice Coverage
WOW! Here was impressive view of Lake Superior on a sunny Saturday, March 29th. Interestingly, the lake was still nearly 91% ice covered as of yesterday!

According to NOAA's GLERL, Lake Superior was officially 90.9% ice covered as of Saturday, March 29th

Great Lakes Ice Coverage
According to NOAA's GLERL, the Great Lakes ice coverage was down 71.1% as of March 28th, which is down from the 2013-2014 peak of 92.2% on March 6th (the most since 1979). The record Great Lakes ice coverage was 94.7% set in 1979.

Soggy Saturday in Florida
Thanks to my good friend Todd Frostad for the picture below out of Sarasota, FL where rain made for a somewhat soggy Saturday.

Stormy Saturday in Florida
This was the radar picture from around 4pm EDT Saturday. Quiet a few showers and storms rumbled across the state making for more of an indoor day. The good news is that weather conditions will improve into Sunday/early next week!

Precipitation Last 7 Days
Thanks to a more active jet stream, weather conditions across the country have been quite a bit more soggy. Take a look at how much precipitation we've seen from coast to coast in the last 7 days! Other than the Desert Southwest, just about every location has seen some type of precipitation since last weekend.

Storm Reports Past Week
Not only have we had quite a bit of moisture over the last week, but there has also a fairly significant uptick in the severe weather as of late. Note that we've had severe weather reports from coast to coast over the last 7 days!

2014 Tornado Count
As of March 28th, the 2014 PRELIMINARY tornado count was only 64 across the nation. Interestingly, at this time last year, we had 147 tornado reports through this time, while in the year 2008, we had nearly 500 tornado reports through this time! The average (2005-2013) through now is 232, so needless to say, we are well behind where we typically are by this time of the year.

Active Weather Continues
The active weather pattern looks to continue across the country into next week as another piece of energy from the Pacific traverses the Rockies and into the Midwest by Monday and Tuesday. This particular system will not only dump copious amount of moisture in the western part of the country, but it will also be responsible for another heavy snow chance from the High Plains to the international border across the Upper Midwest.

Precipitation Outlook Next 5 Days
The precipitation outlook over the next 5 days certainly looks from the West Coast to the central part of the country as our next storm system takes shape. Note that the higher elevations in the western part of the country look to pick up snow, while those from the Dakotas to the far northern reaches of the Upper Midwest will see some too.

Wettest March on Record for Seattle, WA!
As of Friday, Seattle has seen 8.89" of precipitation for the month, which is officially the wettest March in recorded history! Thanks to my good friend Nicholas Shipes for sending this picture who snapped this earlier last week on one of their soggy days.

Winter Weather Ahead
Here are all of the winter weather headlines that have been posted across the nation. Note that not only are places in the higher elevations out west and the places in the Midwest under winter weather headlines, but lingering winter weather headlines are hanging on the Northeast through the end of the weekend.

U.S. Snowfall Potential
Snowy swaths. Here's the snow potential through AM Tuesday across the nation. Note the snow blobs across the Midwest and the Northeast. Apparently winter is hanging...
