.DISCUSSION...The main impact today will be thunderstorm
development from southern Idaho County, Lemhi County east and
north towards the Butte area. While instability is lacking for
storms to become severe, they will still contains gusty winds,
dangerous lightning and small hail. Showers will continue tonight
and there could even be a few night-time thunderstorms mainly
focused from the Bitterroot Mountains eastward. The remainder of
the region will be warmer than normal with highs reaching into the
80s and 90s.

The remainder of the week expect warmer than normal temperatures
and dry conditions. Due to the ridge flattening a little bit on
Wednesday, breezy conditions will develop but shouldn`t be too
strong to impact area lakes.

Models have been trending towards more of a trough dropping out
of British Columbia this weekend. If this were to occur, then
temperatures could be cooler than forecast with increased cloud
cover and perhaps some shower activity confined towards the
Canadian Border and Glacier National Park areas.



Moisture from the southwest monsoon will move over Northern
Rockies air space during the next 24 hours, bringing increased
cloud cover for KMSO southward, as well as showers and
thunderstorms near KSMN and KBTM after 16/1800Z. There will be
areas/periods of obscured terrain south of KMSO 16/1800Z onward.
For the most part, typical modest afternoon winds will be present
at all major terminals, however winds near thunderstorms will
be temporarily gusty and erratic.
