Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
224 PM MDT Fri Apr 18 2014

...POTENTIAL FOR HEAVY SNOWFALL TUESDAY THROUGH THURSDAY NEXT WEEK...

.Discussion...Rain and snow showers will continue through this
evening as a weather system moves through. Expect strong gusty
winds at valley and mountain levels to diminish by late this
evening. A ridge of high pressure builds into the region Saturday
allowing for a cold morning giving way to a warm and dry
afternoon.

A strong frontal system will bring gusty winds late Saturday
evening and continue overnight with little precipitation expected
in the mountains. Sunday will be slightly cooler and breezy with
scattered showers.

There is the potential for an impressive storm during the middle
of next week that could bring an extended period of inclement
weather for both valley and mountain locations. It is a little too
early to pinpoint rain and snow amounts, but this sort of weather
system could bring chilly and wet conditions, heavy snow along the
Continental Divide and increased avalanche danger.
