.DISCUSSION...
-- Changed Discussion --
High pressure will remain established over the
Northern Rockies through Sunday. This pattern will keep
precipitation out of the forecast and daytime high temperatures
above average. Sunday will be the warmest day, with high
temperatures getting into the low 80s in the lower valleys of
western Montana and the upper 80s for the lower Salmon and
Clearwater River valleys of Idaho.

By Monday, the ridge will flatten and upper level flow will become
northwesterly. Model guidance is showing some shortwave energy
embedded in the larger scale flow moving across the Idaho
Panhandle and northwest Montana. This disturbance will bring
enough moisture to fuel showers over northwest Montana. An
associated cold front will drop temperatures closer to seasonable
norms. The front will also bring gusty westerly winds on Monday
afternoon. Model ensemble solutions diverge by the middle of next
week.
