Western Wyoming was under overcast skies on Saturday as a Pacific trough brought periods of moderate to heavy snowfall to the region. Strong southwesterly ridgetop winds at 20 to 30 miles per hour accompanied this snowfall. Mountain temperatures rose into the low to mid 20s as the valleys climbed into the mid-30s.

In the Tetons and the Southwest Trails area, six to eight inches of new snow containing around three quarters of an inch of water accumulated. Four to six inches, with up to six tenths of an inch of moisture, fell in the Togwotee Pass area. Today's weather event produced new winds slabs in exposed terrain near ridgelines, which formed on sun crusts and surface hoar.

FORECAST FOR Sunday, November 23, 2014

A cold front will move through the region this evening bringing another burst of moisture before snowfall intensity decreases to scattered showers. An additional two to four inches of new snow could accumulate by Sunday morning with continued light snowfall through the day. Overnight lows in the mountains will drop to near 10 degrees before rising into the mid-teens in the afternoon. Westerly ridgetop winds will range from 20 to 30 miles per hour.

The general avalanche hazard is expected to be MODERATE on Sunday. Backcountry travelers venturing into steep, wind-loaded avalanche terrain could trigger newly developed wind slabs 10 to 15 inches deep. Weak, faceted snow exists near the base of the snowpack on shaded aspects at the higher elevations. With Saturday's additional load, skiers and riders might be able to cause failure of this weak layer and release slabs with depths up to 30 inches.

TREND FOR Monday, November 24, 2014 AND Tuesday, November 25, 2014

Scattered flurries will persist into Monday. Similar avalanche conditions will continue.
