Heavy snow is falling across the area on Thursday morning with 24-hour snow totals (as of 5 am Thursday) including 7″ at Jackson Hole Ski Area, 11″ near Surprise Lake in GTNP, and 5″ at Snow King. A Winter Storm Warning remains in effect for the Teton Mountains through Friday (issued by the NWS in Riverton), and a Winter Weather Advisory is in effect for the Jackson Hole Valley.
Heavy snow will continue through Thursday afternoon with some lulls expected this evening before picking up again late Thursday night as a cold front approaches. Additional snowfall Thursday-Thursday night will range from 6-12″ in the Tetons. Temperatures at 9,000 ft will be in the low 20s during the day Thursday.
For the valley and town of Jackson, another 1-2″ will be possible early Thursday morning but temperatures warming into the mid 30s will limit accumulations for the rest of the day and lead to some melting. Thursday night, another 1-3″ can be expected for the valley once temperatures drop below freezing. Wind gusts of up to 30 mph can be expected in the valley on Thursday, with gusts of up to 50 mph in the mountains.
Snow will continue through the day Friday and into Friday evening with additional amounts of 4-7″ in the Tetons and 1-3″ in the valley. The snow on Friday will be drier and more powdery, and temperatures will also be colder with highs near freezing in the valley and highs of around 10 (not factoring the wind chill) at 9,000 ft. Storm total snowfall through Saturday morning of 16-24″ (possibly even higher) can be expected for the Tetons with roughly 6-12″ for most of the valley (not factoring in melting Thursday afternoon).
