Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
232 PM MDT Wed Apr 23 2014

...Cool and wet conditions will persist through early next week...

.Discussion...Very moist and cooler than normal conditions will
continue. There will be a barrage of Pacific weather systems with
relatively no break between until the potential for a milder and
drier pattern builds by the middle of next week.

There is a window of relatively drier weather especially across
northwest Montana Thursday night into Friday morning but that will
be short-lived as steady moisture will move back in later in the
day.

The Friday into Saturday weather system will be very similar to
the system that moved through Tuesday and Wednesday today. There
could be areas that receive snowfall by Saturday morning.
