Unusually Warm Christmas For Much of USA – 2021 Weather Disasters – Perspective on Record December Tornadoes – Odds of White Christmas Shrinking

Finding Christmas Joy In a Viral Blizzard We are having a Covid Christmas this year. A family member visiting for the holidays tested positive, has mild symptoms, and now we are isolating, so as not to potentially infect other members of our family, including our 22-month old grandson. Like so many families we are making the best of troubling events beyond our control. Expect low 40s and a few rain showers today before we cool off Christmas. Pieces of a massive west coast storm will break off and approach Minnesota in the coming days – by the end of next...

Significant Snow Brewing Upper Midwest – Hurricane Trends – Clean Energy Revolution Will Be Weather-Optimized

ECMWF Guidance Through Saturday Eveningweatherbell.com Plowable Snow Friday – 50s Next Week? Talk about weird weather gyrations. Monday morning we woke up to a wind chill of -16F in the metro. Models are hinting at 50s next week, a week before the Winter Solstice. Clickbait? Weather hype? Perhaps. We will have snow piles, which will put the brakes on how warm it can get. The sun angle is about as low as it ever gets. Caveats aside, a nice (?) warming trend is likely by midweek; possibly 20-25F above average. But first we have to focus on a storm about...

Fox Weather Channel – Odds of a White Halloween – Remembering 1991 Minnesota Halloween Blizzard

Paul Douglas Extreme Weather Affecting Moving Plans? A recent Redfin.com survey shows nearly half of Americans considering a move are factoring extreme weather events and climate change into their plans. It’s hard to find a spot with no weather-risk, but certain areas are more vulnerable: rising seas and consistently stronger hurricanes for Florida and the Gulf Coast. Bigger fires and more smoke in California and much of the western US. Concerns are growing about water shortages from Las Vegas to Phoenix. Simulations suggest a slow, inexorable northward migration in coming decades. Minnesota may be a net beneficiary of these trends....

Infrastructure Risk From Severe Flooding – Naming Heat Waves – Implications of La Nina?

Lake Minnetonka at SunsetPaul Douglas Cool-ish. The maps still don’t look like late October for much of the USA. Prevailing winds are whisking the coldest air well north of the USA; we are just experiencing glancing blows of chilly air east of the Rockies, a pattern which may remain largely intact through the end of October. October Rainfall To DatePraedictix October Rainfall Departures. Rainfall this month is running above average for parts of central and northwestern Minnesota into the Red River Valley and Dakotas – while a deficit lingers for much of southern and eastern Minnesota and much of Wisconsin....

Fall On Hold For Much of USA – Disaster Fatigue – Calculating Your Home’s Flood Risk

Weather BlissPaul Douglas Weather Models Are Only A First Guess My father still thinks I forecast weather by looking out a west-facing window. I have nothing against using an “Amish Doppler” to gauge the current state of the clouds and sky. To be able to predict the future one needs to first grasp the present. Meteorologists have dozens of weather models to choose from. Which one works best in a pattern like this? What are the trends in models (wetter, drier, warmer, etc?). George Box said “all models are wrong, but some are useful”. They are merely a guide, not...

Ida’s Legacy: Historic Flood and Kansas-Size Tornadoes Paralyze Northeastern US

MN Drought Eases Slightly From Last WeekUS Drought Monitor Weather Extremes Trending More Extreme I’ve been tracking weather systems for 45 years, but nothing has prepared me for 2021’s dueling weather disasters. Our weather models have consistently underestimated the intensity of drought, fires and eastern floods. Why? Climate-warming greenhouse gases have doubled since preindustrial times, and these man-made gases are flavoring all weather now. Are too many people living in vulnerable areas? Yes. But Wednesday’s 1-in-500 year flooding from Philly to New York City and Texas-size tornadoes in New Jersey are more symptoms of our new reality. Flashes of Lukewarm....

Top-10 Hottest Summers – Weather Disasters 4-5X More Common Than 1970s – 200 Year Flood and Kansas-Sized Tornadoes Reported from Philadelphia to New York City Suburbs

Climate Central 2021 Summer Heat Records. Climate Central has a good overview of a very hot summer for much of the USA: “Summer 2021 was definitely a “Summer of the Extremes” as floods, fires, drought, intense heat, and powerful storms ripped across the U.S. and the globe. Record or near-record heat baked the U.S. this summer, especially the Pacific Northwest. Climate Central conducted its own analysis on local heat records and found that 38% (538) of 1396 locations had one of their 10 hottest summers this year. Heat wasn’t the only extreme weather event this summer. Across the nation, many...

Louisiana Left Reeling from “Ida” – Hurricane Strength Was No Surprise to Forecasters – Mandatory Fire Evacuations in Tahoe Basin

Paul Douglas Why September May Offer Year’s Best Weather ”September tries its best to have us forget summer” wrote English philosopher Bernard Williams. I love all the seasons (and the fact that Minnesota HAS 4 seasons) but September is my favorite month of the year. Days are still lukewarm, lakes warm enough for one or two more dips. Severe storms are rare as the noisy blur of summer fades into comfortable days with cotton-ball cumulus and low humidity. That is all fine and good but Minnesota is still too dry and dusty. According to the local DNR “As of this...

Flood Potential in the Middle of a Drought – USA’s Water Haves and Have-Nots?

Twin Cities National Weather Service A Risk of Flash Floods During a Drought ”Papa, tell me the story about the year we had floods during a drought?” Well Jordan, the year was 2021, and it was bone-dry. Parts of Minnesota were on fire. Farmer were worried, even the trees were stressed and losing their leaves early. And yes, we went from drought to flood in the meteorological blink of an eye. Strange? You bet. But I’ve seen rainbows after a tornado, rain the middle of a blizzard. Nothing surprises me much anymore. Excessive Rainfall/Flooding PotentialNOAA Nothing to See Here –...

New Residents Flood Into Drought-Stricken States – Water Levels in Salt Lake Hit Record Low – How Much Heat Can Humans Endure?

This Summer 80s Are “The New Cool Front” I’m happiest when Mother Nature isn’t trying to murder me. To be alive is to live with risk. We have no active volcanoes nearby, no earthquake faults or rising seas to worry about. The biggest temperature swings are found near the center of continents, well away from the moderating influence of ocean water. Large extremes can lead to powerful storms and fronts capable of hail, high winds and (rare) tornadoes. Drought this summer has reduced the severe storm count, but yesterday’s sauna-like airmass whipped up gangs of supercell storms along thunderstorms. Exhibit...
