Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
251 PM MDT Sun Apr 20 2014

.Discussion...Monday is likely to be the nicest day for quite some
time with above normal temperatures. But all this will change
starting Monday night as an approaching storm system spreads
developing showers across the region. Widespread precipitation is
expected to begin in earnest on Tuesday and persist through
Wednesday morning. Snow levels will be lowering so rainfall will
quickly transition to snow which may be heavy at times. Gusty west
winds will make things quite raw with low visibility due to
blowing snow. There might be a brief break in the precipitation on
Friday before yet another weather system moves in for the weekend.
