.SHORT TERM...valid for Tdy and Mon...

The deep upper low that brought significant precipitation to most
of southern Montana and northern Wyoming the last few days has
moved into the Dakotas this morning. An upper ridge over the
western US will build into the northern Rockies through Tuesday.
This will translate into dry and warmer weather through the early
part of the week. It will be less windy today but some gusts of
25-30 mph will hold in the east. High temperatures will return to
near seasonal values today over western and central zones, with
the east remaining a little cooler. Monday will see temperatures
reach the lower to mid 70s. TWH

.LONG TERM...valid for Tue...Wed...Thu...Fri...Sat...

Inherited forecast for the extended period appears in pretty good
shape...so little in the way of changes at this time. Upper level
ridging in control over the region to start the period...then
transitioning to southwest flow by Thursday...and a cooler and
increasingly unsettled pattern through the remainder of the
period.

Temps Tuesday appear to be well above normal...with ridging in
place and a weak wave will help with some compressional
heating...forcing temps into the 80s once again. This wave is
dry...but does help shift ridge axis eastward. Dry conditions
continue through Wednesday night...as southwest flow aloft deeps
ahead of the approaching Pacific Trof.

Another weak disturbance on should bring slight chances of showers
to western mountains and near foothills. Upper level trof slowly
pushes eastward...radiating impulses through the southwest flow. A
slow moving...but stronger shortwave...will impact western
mountains Friday afternoon...and push eastward through Saturday
night. Saturday and Saturday night appear to be our best chances
for precip at this point. AAG

.AVIATION...

Gusty northwest winds continue in the east...but are expected
to slowly taper off throughout the day. Otherwise...no flight
hazards are expected today. VFR conditions will prevail under
partly cloudy skies. AAG
