JACKSON, Wyo. – A strong storm will bring significant snow to the Tetons and Jackson Hole Valley on Thursday and Thursday night as an active early season pattern continues. Strong southwest winds and heavy snowfall rates will result in poor travel conditions for the Thursday evening commute.
Snow is beginning across the area on Thursday morning at the leading edge of the storm. Snowfall rates will then become heavier on Thursday afternoon and evening before tapering off to light snow showers after midnight on Thursday night.
Snow totals from Thursday morning through Friday morning will range from 7-14 inches in the Tetons above 8,000 feet (including the pass) and 3-7 inches in the Jackson Hole Valley.
Winds will be strong out of the southwest throughout the day on Thursday and Thursday night, resulting in dangerous driving conditions with blowing and drifting snow expected in open/exposed areas. Teton Pass commuters should allow for extra time to travel on Thursday evening.
Snow showers will linger into Friday morning on the backside of the storm before clearing out by Friday afternoon with improving visibility. Gusty winds out of the west will continue on Friday, however, resulting in areas of blowing snow.
High temperatures on Thursday will reach the low 30s in the valley and will remain steady through the evening before falling into the low 20s on Friday morning behind a cold front. Temperatures will remain steady in the upper teens to low 20s in the valley during the day on Friday before falling below zero on Friday night.
For skiers, the snow is arriving at a good time with new terrain expected to open up this weekend. If you’re heading into the backcountry, be sure to check in with the Bridger-Teton Avalanche Center forecast as avalanche danger is expected to increase.
