Weekly Weather Update – December 2

JACKSON, Wyo. — Another round of snow has moved into Jackson Hole on Monday following a big storm cycle over Thanksgiving. A Winter Weather Advisory from the National Weather Service is currently in effect for the Teton and Gros Ventre Mountains until 11 p.m. Monday evening with difficult travel conditions expected over Teton and Togwotee Passes.

Snow Through Monday Evening

A weaker storm is impacting Western Wyoming on Monday. Snow arrived early Monday morning and will continue throughout the day into Monday evening.

Snowfall amounts prior to the 5 a.m. report totaled 1-2” across the Tetons and Jackson Hole Valley. Additional snowfall amounts Monday through Monday night will range from 4-8” across the Tetons and 1-3” in the Jackson Hole Valley. Monday afternoon and Tuesday morning will offer the best skiing conditions.

Warmer air is arriving with this storm, which will result in highs in the mid-30s for the town of Jackson. This should allow for some softening or melting of snow on the roads in the valleys Monday afternoon.

Snow will linger into Monday evening before tapering off after midnight.

Avalanche danger is currently forecasted to be CONSIDERABLE according to the Bridger-Teton Avalanche Center.

Quiet Stretch of Weather Tuesday through Friday

Following Monday’s storm, drier conditions can be expected for Jackson Hole for the remainder of the work week. Lingering moisture and clouds will remain on Tuesday with occasional snow flurries, but it won’t amount to much.

On Wednesday, a storm passing south of the area will result in scattered to mostly cloudy skies, but otherwise conditions will remain quiet. Thursday and Friday, we will have a better chance of seeing some breaks in the clouds.

High temperatures from Tuesday through Friday will generally be in the 30’s most days in Jackson as the pattern does not look particularly conducive to inversions. However, if inversions do manage to develop then high temperatures will be colder than forecasted.

Snow Returns Saturday and Sunday

The next storm system is projected to reach the Tetons this weekend. The details of this storm will come into better focus later this week, but for now it appears the highest travel impacts will be from Saturday afternoon through Sunday morning. Sunday morning should also offer the best skiing conditions of the weekend.

Snow Totals from November 27-30

Jackson Hole received heavy snow amounts over the Thanksgiving holiday, with up to three feet falling in the Tetons and about a foot in the valley!

Below are some of the snowfall totals recorded from Wednesday, November 27th through Saturday, November 30th:

36.0” – Jackson Hole Ski Area (Rendezvous Bowl)
31.0” – Grand Targhee
