.DISCUSSION...Abundant sunshine, relatively light winds, and very
warm temperatures (80s to low 90s in the valleys) are expected
today under high pressure. Monday will be a few degrees warmer
compared to today but changes are on the way later in the day.

As the upper level flow turns southwesterly, abundant moisture
will enter the region by Monday afternoon/evening. Showers and
thunderstorms will begin to fire off in the Northern Rockies,
bringing threats of heavy rain, frequent lightning, gusty winds
and hail. This storm activity will shift into west-
central/southwestern Montana and central Idaho overnight into
Tuesday. Active thunderstorm activity will continue through
Tuesday afternoon for these regions as the system tracks
southeastward. Daytime temperatures will be noticeably cooler for
Tuesday compared to Monday, and breezy westerly winds will
continue under this pattern transition.

For the latter half of this week, forecast models continue to
move a low pressure system through southern Canada leading to a
cooler northwesterly flow pattern as temperatures return to
seasonable levels. Shower and thunderstorm chances are expected
each afternoon (especially across Northwest Montana) along with
breezy afternoon winds.
