Tomer’s Take: Today is transition day with a storm system hand-off. Snow continues 1/11 in CO/NM diminishing from north to south. Then snow redevelops WA/OR/MT/ID/WY/CO on 1/12 as an Arctic front barrels south. Air temps run 30 to 50 degrees below normal. A storm system rides this Arctic front with strong orographics, high snow ratios, and a jet blast. 40-70mph wind gusts likely in UT/WY/CO on 1/12-1/13 raking the high peaks. Another storm system hits BC/MT/ID/WY/UT/CO 1/16-1/19 with a NW flow orientation.
In the Northeast, a strong storm system arrives 1/12-1/13 with 70mph gusts and heavy snow changing to rain/snow VT/NH/ME. What once looked like a promising snowstorm on 1/16-1/17 is tracking even further south now with less accumulation in VH/NH/ME. Another storm system arrives 1/19-1/20 with heavy snow potential.
My afternoon forecast video update:
Heavy snow continues today at Aspen/Snowmass with 4-8 inches of accumulation.
Snowbasin, UT is reporting 12″ in 24 hours. I’m forecasting another 1-2 feet across the Wasatch 1/10-1/11.
