Forecast for Bridger-Teton National Forest Avalanche Center
National Weather Service Riverton WY
415 AM MST Thu Feb 22 2018


.DISCUSSION...

A large and expanding upper level trough will remain in control of
the area through the weekend. Another very cold and quiet (with
respect to the wind) morning/day is expected today with only small
chances for a few light snow showers continuing over the area`s
mountains through Friday night. Better chances for measurable
snowfall and increases in winds will arrive Saturday (winds arriving
a bit ahead of the increase in snowfall). A lull in the action will
take place Sunday before increasing precipitation chances once again
Sunday night, continuing into Monday night.
