Forecast for Bridger-Teton National Forest Avalanche Center
National Weather Service Riverton WY
303 AM MST Mon Dec 18 2017


.DISCUSSION...Western Wyoming will be under a moist westerly Pacific flow during
the next few days. This moist upslope flow will produce just light
snowfall and light accumulations through Tuesday night. Without much
in the way of other atmospheric dynamics, upslope flow alone will
keep snowfall amounts light. This westerly flow will result in
west winds 30 to 40 mph on the higher ridges. Cloud ceilings
today will range from 2 to 4k above the valley floors. By
Wednesday, a cold Pacific trough of low pressure will produce a
few inches of fluffy powdery snow followed by the coldest air of
the season in the weather system`s wake later in the week.

Forecaster...Lipson
