Western Wyoming PM Forecast

Issued on Fri November 27, 2020 6:05 PM

Situation

Skies became mostly sunny as the eastern edge of a high-pressure ridge builds into the region. Temperatures in the mountains rose into the 20s from overnight lows in the single digits. Winds were from the north to northwest at 10 to 25 miles per hour.

Snowfall associated with a cold front that passed through two evenings ago favored the western and northern portions of the Teton Range. At the upper elevations this system may have formed some shallow wind slabs.

Forecast For Saturday, November 28, 2020

Dry weather will continue with steepening temperature inversions and a light west-northwesterly flow. Skies will be mostly sunny above areas of morning valley fog.

The general avalanche hazard is low. At the upper elevations humans who venture into steep avalanche starting zones could trigger shallow wind slabs up to one foot in depth. Small slides can have serious consequences in unforgiving terrain. Hazards associated with shallow snow depths are prevalent.

Trend For Sunday, November 29, 2020 AND Monday, November 30, 2020

This appears to be the beginning of an extended dry period. Significant changes in the avalanche hazard are not anticipated.
