Tomer’s Take: Two areas of low pressure deliver snow to UT/WY/CO 12/23-12/24. A major storm system hits the PNW/BC with heavy snow 12/25-12/26, and the Sierra might get heavy snow 12/29-12/30.
A storm system crosses the Intermountain West on/about 12/30-12/31 with light to moderate snow accumulation.
My forecast video:
5″ in 24hrs at Alta, UT with another 1-3″ before the storm departs.
Current Setup
Water vapor satellite shows both areas of low pressure merging over UT/WY/CO.
An active Pacific jet inbound to PNW/BC.
Orange/red = drier air aloft.
Forecast Jet Stream
Forecast pattern 1/1/2024. Active flow with both northern and southern branches.
Forecast Totals
UT Wasatch: An additional 1-3 inches 12/23 then drier 12/24 (and beyond).
CO Snow: 12/23-12/24 & 12/30-12/31.
CA Snow: 12/27 (light), 12/29-12/30 (Heavy).
VT/NH/ME: Rain on 12/27 and it *might* change to snow 12/28. Light snow 12/30-1/1.

Merry Christmas! to all the TOMER faithful out there.
I’d like to send Chirs gifts of : lots of clouds, southern Lows, arctic blasts, and most importantly Pineapple Express blasts which are orographically aligned over the Inter-Mountain west.
Cheers to Loveland, Jackson Hole, Mt. Shasta, Alta, Brian Head, and all the other favorite Tomer spots.
Thanks, Randall! Merry Christmas
