Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
203 PM MDT Tue Apr 22 2014

.Discussion...

A relatively cold spring storm system will be over the Northern
Rockies through Wednesday. Several inches of snow are likely at
mountain pass elevations and higher. Daytime temperatures will
warm to at least freezing for all except the highest elevations.

Thursday will be a transition day, with temperatures warming back
to seasonal.

Another weather scenario similar to today will likely replay on
Friday and Saturday, with several inches of high elevation snow
and relatively cold temperatures.

Weather models are projecting a dry and warm period beginning
Sunday through much of next week, however there is low confidence
of this forecast.
