.DISCUSSION...
Seasonably cool and dry weather will continue to round out the weekend
in the Pahsimeroi Mountains ahead of an approaching upper-level trough
that will work south through the Rockies heading into early next week.
Isolated snow showers overnight tonight into Monday morning will
transition to a mix of rain/snow showers and thunderstorms by Monday
afternoon with a 15-25% chance of thunderstorms. Winds will also
remain breezy, peaking each afternoon with gusts to around 25-30 mph
out of the N/NW. Drier conditions are then favored to return for
Tuesday with precipitation chances less than 20% ahead of the arrival
of our next system moving in for that Wednesday/Thursday timeframe.
