Area Forecast Discussion

434 AM MDT Mon Jul 16 2018

.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.
