CB Avalanche Center Weather

We will kick that high pressure and above normal temperatures to the curb today, as a strong Pacific storm churns its way across the Great Basin this morning, leaving us with very different weather by sunset. A strong cold front currently located around Vernal, Utah (4am) will march into Colorado by midday, and we should see gusty winds, an intense period of precipitation, and possible thunderstorms this afternoon. Snow levels will initially ride high (9-10,000ft) this morning, falling during the afternoon to valley bottom by midnight. The changeover to snow will determine the amount of snow accumulation our mountains will see. Strong southerly winds will usher in the cold front today, with strong northwesterly winds behind the front, slowly decreasing by Friday midday.

SPECIAL GRAND TRAVERSE WEATHER: This potent storm system will be short-lived and move quickly out of the race corridor by Friday midday. 8-12” of new snow looks possible, but will hinge on how quickly any rain changes over to snow and how much northerly flow robs or enhances the race course of moisture. Northwest winds look to peak Friday morning around 6am, with nearly calm conditions and temperatures in the teens at Star Pass race night. The CBAC will issue an updated race forecast tomorrow morning.
