Deep powder alert for the Tetons with 18″ of snow reported at Jackson Hole Ski Area over the past 24 hours. Jackson Hole Valley snow totals have been a good bit lower in the 3-5″ range as this storm has largely been terrain driven. Snow will continue to fall throughout the day Thursday and into Thursday evening with another 5-10″ for the Tetons and 1-3″ for the valley, before tapering off after midnight.
Temperatures will remain steady in the mid 20s in the valley on Thursday, while mountain temperatures at 9,000 ft will gradually fall into the single digits through Thursday afternoon. Lows Thursday night will fall to around zero in the valley once skies begin to clear. Mountain winds on Thursday will be out of the west/northwest at 10-20 mph with gusts to 30 mph, while valley winds will be out of the southwest at 5-15 mph with areas of blowing snow possible in open areas due to the dry/powdery nature of the snow.
Cold and dry conditions will prevail on Friday with skies becoming mostly sunny. Highs Friday will be in the upper teens in the valley and low teens at 9,000 ft. with generally light northwest winds. The break will be short-lived as the next storm arrives late Friday night and continues through Saturday with additional heavy snow amounts likely. Cold temperatures at all elevations will result in another low-density, powdery snowfall.
