Behind the “Atmospheric River” That Flooded British Columbia and Washington – In Praise of Snow – Lowering Temperature on Wildfires?

Paul Douglas In Defense of Snow Days ”A lot of people like snow. I find it to be an unnecessary freezing of water” quipped comedian Carl Reiner. I can live without 20 below but I don’t mind the snow. It’s an insulator, shielding plant life from extreme cold. It’s a moisture supply: melting snow fuels spring’s miraculous rebirth. You can PLAY in frozen water! You can’t surf a hurricane storm surge, or hike up an active volcano (ill-advised) or savor a heat wave. Pick your poison – I’ll take a white-washed pile of flaky fun any day of the week....

Origin of Phrase “Jet Stream” – Greenland Melting Threatens More Coastal Flooding – Building Back Climate-Resilient

500mb (18,000 foot) wind speeds at 18Z Wednesdaypivotalweather.com The Jet Stream Makes For Bad Hair Days ”Blow, blow, thou winter wind. Thou art not so unkind, As man’s ingratitude” wrote William Shakespeare in “As You Like It”. The winds are howling, a symptom of a roller-coaster ride in the temperature department. The “jet stream” was discovered in the 1920s by Japanese meteorologist Wasaburo Ooishi, who launched weather balloons. High-speed jet stream headwinds were encountered by B-29 pilots flying west toward Japan on bombing runs during WWII. They often missed their targets and sometimes ran out of fuel, due to a...

Thanksgiving: Cold/Stormy East – Mild West. NOAA: Warm Signal Lingers Into February

Paul Douglas Outlook: Cool, Quiet (and Mostly Dark) I dare you to go one day without complaining about how early the sun sets. By the way sunset is 4:44pm. 9 hours 32 minutes of daylight. The sun angle in the southern sky is equivalent to January 26. Which makes me extra-happy we’ll enjoy a high near 50F later today, almost 10F above average. November is running 3.4F milder than average, with a whopping 1.2 inches |PART3: of snow at MSP. The last I checked meteorological autumn is the 3rd warmest on record in the Twin Cities, to date. We’ve had...

Direct Davis Instruments Support on PWSweather.com

AerisWeather’s own PWSweather.com has been providing a beautiful, secure way to monitor, manage, and archive weather station data for over a decade. Over those years, we’ve developed an intimate understanding of the needs and functionality demanded by weather station owners from all walks of life. This information has helped extend our environmental data expertise beyond traditional weather stations to encompass more modern technologies, including Internet of Things (IoT) devices. As part of this mission to source environmental data from a diverse portfolio of devices, the PWSweather Team is excited to announce direct weather data ingestion support for AEM’s Davis Instruments weather stations...

Mild East – Wintry Upper Midwest – Warming Climate Juicing Heatwaves

Winter Pangs? We’ll see 40s next week, but 500mb guidance roughly 2 weeks out shows prevailing jet stream winds buckling, allowing another shot of cold air to sail south around Thanksgiving. Confidence levels are low – there is no continuity from model run to run. Praedictix Briefing: Issued Thursday, November 11th, 2021 The first winter storm of the season will impact portions of the Northern Plains and upper Midwest today into Friday, with light to moderate snow expected to fall and strong winds in place. The heaviest amounts of snow (potentially over a half a foot) is expected to fall...

Significant Snow Upper Midwest – Mild Thanksgiving Potential – COP26 Climate Update

Des Moines National Weather Service Slushy Coating Possible Friday. With temperatures above freezing and a little rain mixing in with wind-whipped snow, I’m not terribly excited about accumulating snow in the MSP metro, although healthy amounts of slush are likely over far northern and western Minnesota. Thursday Future Clouds/PrecipitationPraedictix “Backlash”. Meteorologists love to make up words and phrases that attempt to describe what’s going on – moisture rotating all the way around a strong storm will approach from the north and northwest later today into Friday, with temperatures cold enough for light snow across most of the state – although...

Major Coastal Flooding Event Southeast Coast – October Tornado Count Close to a Record – COP26 Climate Update

Going out in a blaze of gloryPaul Douglas Chilly, Not Polar. After a potentially slushy cold weather correction late next week long range models hint at (slight) moderation before Thanksgiving – the flow still zonal, pumping in relatively mild air from the Pacific 2 weeks out. Major Coastal Flood Event, Similar to a Hurricane Storm Surge, Underway in Charleston, South Carolina. An extended stretch of high, onshore winds are to blame. CNN.com has details: “A potentially historic flood event is taking shape across Charleston Harbor, South Carolina, and portions of coastal Georgia, including near Savannah, as water levels will be...

Supernaturally Mild Across Much of USA Into Mid-November – Boston Among US Cities Most Vulnerable to Hurricane Damage

Paul Douglas Bad News For Hunters and Pond Hockey Fans My sense: most Minnesotans are enjoying this extended weather honeymoon, with flashes of September warmth showing up in early November. But not everyone. Hunters are irritable. WCCO Radio’s Mike Max had a special weather request for duck hunting in North Dakota. “Paul, I’d like low clouds and a northwest breeze”. Yep, and I’d like a shiny new Doppler, but that isn’t going to happen either. Praedictix meteorologist Todd Nelson wants snow for tracking during Saturday’s Deer Hunting Opener. “Would you settle for heavy frost?” I inquired, hoping to find common...

“Medicanes” – Wettest Tropical Cyclones in Centuries – Odd Weather Phobias

File: BWCAPhotographer Steve Burns Preparing For An Indian Summer Weekend It looked like the world was covered in a cobbler crust of brown sugar and cinnamon, wrote North Carolina novelist Sarah Addison Allen. The scene outside my frosty window is crunchy, with shades of rust and lemon. The leaves have largely left, and now that we experienced the first frost of the season, we can call this weekend’s warm front “Indian Summer”. It’s a term dating back 2-4 centuries, describing unusually mild weather that allowed Native Americans to continue harvesting and hunting. Pattern Favors Major East Coast Storms. Parts of...
