Imagine experiencing Thundersnow at 8000'?. They'll be getting 4-8" snow tonight.

I love Upper Lows! So awesome

Upper low continues to drop slowly southward through UT with an impressive baroclinic leaf developing across western Colorado in satellite imagery. Impressive lift/isentropic upglide


Current Map and who's reporting what right now. Check out those lightning icons. #Thundersnow

Almost looks like moisture is being pulled from the Gulf Of California or the Pacific? I doubt it and haven't heard anything about that.

That Vortex is just spinning away there. Must be something else to experience this in September... Windy too

If that Upper Low was 200 miles East Kansas would be getting snow.

Snow in Denver right now, looks like the trees have accumulation but none on the ground there:

On the grass but not the roads. That's like what happens in Texas whenever we get snow.

I usually dont sleep when we get snow here in middle of winter. If I had it in September I dont think I would blink at all. Lol

The sun is setting now. Hopefully people stay up to get an accurate measurement because after 6-10hrs you get compacting and melting.

Checking out the 10,000 foot temp air mass. I see why some areas south of Denver changed back to rain or switching back and forth, even though its in the 30s... With the counterclockwise spinning Upper Low There is a southerly flow on the southeast side of it, and that's bringing in some warmer air at the mid level from the south. Position of the Low is so key all the time.

Precip is not heavy enough to overcome this shallow warm layer but will tonight

Warm moist air into a deep cold airmass. Just awesome. And look at that record cold airmass. Even for 10,000 feet!

Wyoming seemed to get the worst of this one. Check out some of these snow and wind totals: https://nwschat.weather.gov/p.php?pi...-NOUS45-PNSRIW

80mph winds at the Rock Springs Airport. Several locations around Lander and Casper reporting around a foot of snow....the day after Labor Day.

Here is a snapshot from Rock Springs earlier today. Notice the wind.

8pm MDT. Grass is covered, and it's starting to stick to the driveway and sidewalk. We'll probably have another inch or two by morning. Not enough to bother shoveling it.
