Forecast for Bridger-Teton National Forest Avalanche Center
National Weather Service Riverton WY
109 AM MST Tue Feb 20 2018


.DISCUSSION...

A large and expanding upper level trough will remain in control of
the area through the week. An Arctic front associated with the snow
event over the weekend has passed well to the south and east of the
forecast area. Otherwise, as high pressure builds across the region
in the wake of the exiting cold front, extremely cold and quiet
(with respect to the wind) conditions will prevail through the rest
of the week. Only small chances for a few light snow
showers/flurries will continue over the northwest mountains through
the rest of the week under general troughiness aloft. The next
chance for significant snowfall does not look to arrive until
perhaps later this weekend.
