“Lumpy Winter” – Tornado Clean-up Dixie Alley – No More Greek Names for Hurricanes

Paul Douglas What a Strange Winter It Has Been On paper our winter has been been “average” in terms of snowfall and temperatures in the metro. It sure hasn’t seemed average to me. Record snows in October, green lawns in December, a fairly balmy January, followed by a frigid February. Lumpy – all or nothing. Dr. Ken Blumenfeld, Senior Climatologist at the Minnesota State Climate Office, was on WCCO Radio with Jordana Green and me Tuesday. He said some things that got my attention. In spite of a polar February, the period November thru March will be one of the...

Will La Nina Turbocharge Tornado Season in 2021 – One to Three Feet of Snow Possible Near Denver This Weekend

“Eye of the Storm”. This was one of my radar screens yesterday as tornadic storms were pushing over Northfield, showing a perfectly concentric “rain hole” over Wright county. Kind of odd, but it quickly dawned on me that this was the center of low pressure rippling northeastward, not some quirky inland hurricane sent here to terrify us. Modified Pacific Flow. A few Canadian slaps, sure, but the flow is predicted to be roughly zonal into mid-March, meaning temperatures at or above normal across most of the Lower 48 states. Briefing: Issued Wednesday, March 10th, 2021: Heavy Snow From Wyoming to...

Flashes of Summer Out East – Hurricane Blind Spot – Is Tornado Alley Shifting?

A Few Cold Slaps. March giveth, and March taketh away. Today’s 2-week forecast of 500mb (18,000 foot) winds valid the evening of March 23 looks colder than yesterday’s simulation. It would be wildly premature to pack away the heavy jackets (or pull out driveway stakes). Global temperature departures from average during February 2021, as compared to 1981-2010.Copernicus Climate Change Service U.S. Sees Coldest February Since 1989 Amid Global Temperature Dip. Capital Weather Gang has details: “…The cold in the U.S., combined with unusually frigid air across much of Eurasia, resulted in global warmth less pronounced compared to recent Februaries, according...

Expanded Global Historical Weather Conditions

Last summer, we introduced the conditions endpoint. Since it’s release, we have been working on improving the endpoint and adding additional data sources and historical weather conditions. Recently, we integrated infrared satellite as an additional data source, and with our AerisWeather API v1.16 release, we are announcing support for expanded global historical conditions. Check out the release history to review the complete list of improvements in this API release. Global Historical Weather Conditions In October, we expanded support for global hourly gap-free weather conditions for the past 30 days and over ten years of historical conditions for limited regions based on observation...

Coldest February Since 1989 – High Resolution Weather Will Power Renewable Energy Sources

NOAA, Twitter Wild Swings. February was the coldest since 1989 for the U.S. – now 60s in early March. In fact, factoring wind chill, today will feel nearly 100 degrees warmer than it did roughly a month ago across much of Minnesota. Incredible. Shifting Gears. We’ll see more cold frontal passages (no kidding) and I expect a few more slushy encounters before daffodils start poking up in April, but looking out two weeks NOAA’s GFS model shows a predominately zonal (west to east) flow, suggesting temperatures slightly above average northern tier of the USA and well above normal over the...

High-Resolution Weather Predictions Will Power the Clean Energy Revolution

High-Resolution Weather Predictions Will Power the Clean Energy Revolution Winston Churchill had it right. The future is a riddle, wrapped inside a mystery, inside an enigma. Predictions are always tenuous, but one thing is increasingly apparent: what worked in the 1970s probably will not work in the 2030s. The election of President Joseph Biden has accelerated a transition to a more sustainable, clean-energy future for the United States. But federal incentives and stimulus are only part of the equation. Market forces are already in play, powering and accelerating an inevitable transition to wind, solar, energy storage, biofuels, tidal power and...

Atmospheric Rivers – Stratospheric Warming Impacting Polar Vortex – Very Little Ice on Great Lakes

Star Tribune Another Low Ice Year Predicted on Lake Superior, Great Lakes. Star Tribune has an update: “As the sun rose over this corner of Lake Superior on Wednesday morning, the windchill was nearly 30 below. Open water at last disappeared under a thin layer of ice after stubbornly sticking it out through an unseasonably warm January. But just over the horizon, the waves remained. For the second season in a row, Lake Superior and the Great Lakes as a whole are expected to have below-average ice, which could increase shoreline erosion and threaten organisms that depend on ice cover,...

The 500mb forecast 2 weeks out looks cold, but there are still hints that our pattern may be flavored by the Pacific, a persistent westerly component to steering winds aloft that may take some of the sting out of any polar air. Still too early to speculate about intensity or duration of any bitter cold. Or if it’s even real. CW3E Scripps, Twitter Atmospheric River in California Poses Debris-Flow Threat.

12-15″ Snow Reported Omaha to Des Moines – Record 50 Global Weather Disasters in 2020

NOAA On The Cusp of Frigid? Looking out 2 weeks GFS guidance shows polar air pooling over Canada, and all it will take is a series of clippers to drag successive waves of increasingly cold air south of the border, arriving in waves of cold fronts. Briefing: Issued Tuesday morning, January 26th, 2021: Central United States Winter Storm Morning Radar. Snow continues to fall from portions of Iowa into the Great Lakes with our central United States winter storm this morning, with wintry precipitation (including freezing rain) stretching east into portions of the Northeast, including Pennsylvania. A band of at...

Major Midwestern Snowstorm – Record 50 Separate Global Billion-Dollar Weather Disasters in 2020

David Josephson, WCCO Radio A Relatively Balmy January. Dr. Mark Seeley has details on lingering warmth in this week’s edition of Minnesota WeatherTalk: “…It looks like this January may end up among the 5 warmest in state history based on statewide climate data so far. Through two-thirds of the month temperatures are running from 8 to 17 degrees F above normal. The last ten days of the month will not all be warmer than normal, but a mixture of above and below normal values. This will mean that the average temperature for January in Minnesota may not be as cold...
