Forecast for Bridger-Teton National Forest Avalanche Center
National Weather Service Riverton WY
117 PM MST Tue Jan 16 2018


.DISCUSSION...
A weak weather system will move across the area late tonight into
Wednesday morning with mainly mid and high clouds. The higher
peaks may see a few flurries but no accumulation is expected.
Valley inversions will continue. Overall, it will be dry through
the day Thursday. Winds will increase Thursday ahead of a storm
system that will arrive later Thursday night through Friday. This
system will have strong southwest wind and a period of heavy snow.
Early indications point to 5 to 9 inches of snow in the western
mountains with the potential for a foot in the Tetons along with
blowing snow. Near the valley floor, the precipitation could
briefly start out as a rain snow mixture before the colder air
moves in late Thursday night.
