Forecast for Bridger-Teton National Forest Avalanche Center
National Weather Service Riverton WY
506 AM MST Mon Dec 17 2018


.DISCUSSION...After mainly dry conditions this morning, a weak and splitting
trough will bring light snow from this afternoon into tonight.
Accumulations should remain light in most locations. After only some
very light snow Tuesday morning, a more potent Pacific system will
move in late Tuesday into Tuesday night and bring a good chance of
moderate to possibly heavy snow. This snow will be accompanied by
gusty winds that will likely blow and drift the snow. Lighter snow
will continue into Wednesday before ending on Wednesday night as
high pressure builds into the area.
