What a winter it’s been across the United States. From Alaska to Florida and from Southern California to Maine, it’s been extreme in all categories. Firstly a record cold open and close to December 2017 with record snowfall for Erie and the state of Pennsylvania. This was followed by the coldest open to a new […]
Thanks to a mid-winter depth trough vs a summer-like ridge, yesterday saw snow and sub-zero wind chills across Montana while at the same time cities in the East where enjoying their warmest February day on record. AMAZING STUFF! https://twitter.com/ericfisher/status/966091592313524224 A 590+dm in summer is strong and produce heat waves but in February, it’s just ridiculous. […]
What a West-East contrast we have over the Lower 48 just now. We currently have a mid-winter level trough over the West bringing the coldest air not just for this winter but in a few years to parts of California while beneath an unusually strong upper ridge and SW flow, we have record February warmth […]
Article from weather.com February 15, 2018 By Brian Donegan and Chris Dolce Imagine seeing the temperature rise more than 80 degrees in just a few hours, but it’s still cold.

A system lifting ENE out of the southern Plains will meet cold air dropping southwards out of Canada and so precip turns to snow from the interior Mid-Atlantic up through New England. Quite the dip in temp between today and tomorrow. From mid to upper 50s late […]
As arctic air brings Montana it’s coldest weather of the season (worse likely to come next 10 days), attention turns from -30 to -40 air, -40 to -60 chill to ground blizzards. Havre, MT shivered at -36 but the coldest place in the state appears to have been Mudd Lake with -42, Chinook hit -40. […]
We have just witnessed the first true sudden stratospheric warming event (SSWE) since January 2013 with a split in the vortex. One piece has pushed over central Arctic Canada and the other into the Europe-Asia border area. The models went from cold to mild for late February which didn’t coincide with the overall picture. A […]
Yep it’s been snowy in Chicago lately, so much so it’s been record breaking! With 20 below normal air over Montana and 20 above normal in the Southeast, there’s a natural fight in between. This comes in the form of a storm series. With track SW to NE but just south of Chicago, this is […]
