.DISCUSSION...

KEY MESSAGES:

- Thunderstorms will be a near-daily occurrence across the region
  with above average temperatures and humid conditions.

- Chance for stronger thunderstorms Friday.

The Northern Rockies are still on track to be under southwesterly
to westerly flow for the next several days. This flow pattern will
be conducive to afternoon and evening showers and thunderstorms.
A few weak disturbances will be moving through this flow pattern
at times throughout the week, which will enhance the shower and
thunderstorm potential. The first disturbance will be on Friday,
which appears to kick off a few storms during the morning hours.
The storms will then intensify during the afternoon across
southwest Montana and along the Continental Divide. The stronger
storms will be capable of heavy rain, small hail, and gusty
winds in excess of 50 mph.

A brief break in the action will occur Sunday, and then the next
significant disturbance to move through will make itself known by
Monday afternoon. Expect scattered thunderstorms to occur across
the region.

In addition to near-daily thunderstorm activity, temperatures will
range above average from central Idaho into western Montana. And
given the amount of abundant moisture in the atmosphere, expect
more humid conditions than usual.
