Western Wyoming PM Forecast
Issued on Sat December 04, 2021 6:12 PM
SituationThis was the final day of an extended stint of dry and usually warm weather. Some clouds moved into the region as the high-pressure ridge that has dominated our weather began to flatten. Today’s temperatures rose into the 30’s on the peaks, to near 40 at the mid elevations and to near 50 in the valleys. Winds increased to 20 to 35 with gusts to near 60 miles per hour.
Current snow surfaces include areas of crust and areas of faceted snow.
Forecast For Sunday, December 05, 2021A cold front will sag into the region from the north overnight. It will bring us stronger winds, colder air and less than an inch of snow. Winds should peak around midnight with gusts as high as 70 miles per hour on the summits. There will be lingering snow showers on Sunday with little accumulation. Temperatures in the mountains will be near 20 by daybreak and should fall into the teens during the day. West to northwest winds will slowly decrease.
The general avalanche hazard is low. The existing snow is currently stable.
Trend For Monday, December 06, 2021 AND Tuesday, December 07, 2021Another storm system will move into the region late Monday and into Tuesday. At this time is it unclear how much snow is expected. Future avalanche hazards will be dependent of how well any new snow bonds to the old snow surfaces that were created during the past 10 days.
