Late-Summer Snow Falls in Northwest U.S. as the Jet Stream Shifts South — Even Colder Conditions on the Way

Cool air funneled into the Western U.S. this week resulting in up to 10 inches of snow falling on the mountains of Utah and Wyoming. While looking ahead to next week, meteorologists see a much more potent cold air-mass sweeping the Pacific coast and Intermountain West.

This week’s cool air, which arrived in the Northwest on Monday, saw temperatures nosedive some 10C below the seasonal average. Snowflakes fell over the high country of the Tetons in northwestern Wyoming early Tuesday. And a decent dumping of the white stuff settled at Bald Mountain Pass, Utah:

Up to 10 inches of snow is expected to fall in the higher terrain of northern and western Wyoming Tuesday night into Wednesday, in what the NWS is calling the first “fall-like storm” of the season.

Bighorn, Absaroka, Wind River and Teton mountains –including parts of Grand Teton and Yellowstone national parks– are all expecting healthy accumulations of powder above 8,000 feet.

With Thundersnow even possible in the Bighorn Mountains on Wednesday.

Studying the jet stream has long been an indicator of the weather to come.

And to study the jet stream, attention must turn to the sun.

When solar activity is high, the band of meandering air flowing some 6 miles above our heads is tight, stable and follows somewhat of a straight path. But when solar activity is low, as it is now (with NASA forecasting this next solar cycle “will be the weakest of the past 200 years”), the jet stream loses strength and its band of fast-moving air becomes wavy which, in the NH, drags Arctic air south to much lower latitudes than normal:

It is 47 here now. Low for tomorrow is 40. The high for today is supposed to be in the low 60's.

Smokin Joe:
Rain, and lots of it, in western ND, night temps in the low 50s. As an aside, this has been one of the wettest years I have seen in the last 4 decades here, everything is still green out there. But the wet conditions are adversely affecting the harvest with harvests well behind 5 year averages. source

I hope the damned thing waves all the way down to Texas!
