...Hot Wednesday...
...Breezy and mild 4th of July...

.DISCUSSION...Some instability will linger mainly over the
Continental Divide, southwest Montana and Lemhi County this
evening. Otherwise, a mostly clear night and a little cooler than
last night should be in store.

High pressure will persist Wednesday with the air mass probably
peaking in warmth. Valleys will see hot temperatures with values
10 to 15 degrees above normal. Some instability will again develop
along the Divide, southwest Montana and Lemhi County...but only
translating into isolated late afternoon light showers or a
lightning strike or two.

A more southwest flow is expected Thursday, Friday and Saturday.
Temperatures will remain quite warm. The southwest flow may
direct very weak disturbances across the northern Rockies and
support late afternoon and evening showers or thunderstorms.

A weakening trough of low pressure is expected to brush north
central Idaho and western Montana late Sunday into the 4th of
July. Temperatures should cool to only slightly above normal.
However, more important, the afternoon and evening winds should
increase, possibly becoming quite breezy on Monday...the 4th.

.AVIATION...A very warm and unstable atmosphere will linger this
evening. A few cumulus buildups and possibly an isolated shower
may develop along the Continental Divide, southwest Montana, and
Lemhi County. Otherwise, high pressure should produce generally
clear conditions into Wednesday morning.

.MSO WATCHES/WARNINGS/ADVISORIES...
