304 AM MDT SUN MAY 29 2016

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

Drier westerly flow will persist today with dewpoints lingering
in the upper 30s. Downslope flow will keep any chance for pops to
a minimum in western zones even though shortwaves continue to
cross the region. Higher dewpoints and lingering instability in
east however may support showers and thunder this
afternoon/ introduced pops in east. Downslope flow
should also help push highs into the upper 70s.

Upper level low and cold front will push across the region
tonight...and across the region Monday monday morning ahead of a
developing ridge over the Western US. Models continue support
early fropa...greatly limiting severe weather potential...however
small hail continues to look likely due to low freezing level.
High temps in the 60s west...and 70s west are expected to occur
early in the day Monday...with cooling during the afternoon.
Increasing cloud cover...and post frontal showers bring
unseasonably cool temps for the evening hours. Gilstad

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

Main change to the extended forecast this morning is for warmer
temperatures late week into the weekend...and less precipitation
potential overall after Tuesday. Models continue to show a cool
wet pattern for Tuesday with upper low over eastern MT shifting
into the Dakotas. Gusty northwest winds and instability will make
for a showery and blustery day. Northwest flow backs to the west
as ridge builds in aloft behind exiting upper low. Downslope
westerly winds will help temperatures back into the lower 70s and
bring dry conditions. Heights continue to rise Thursday into
Friday with downslope westerly flow in the lower levels pushing
highs into the lower 80s for the end of the week. Models this time
yesterday showed a Pacific storm system pushing in for the
weekend, but latest models hold this system off the coast keeping
an amplified ridge in place through early next week. Warmed
weekend temperatures and dried out the late extended as a result.


VFR conditions will prevail today. A disturbance crossing the area
will bring a few showers/thunderstorms this afternoon with local
MVFR conditions possible. Best chances for a thunderstorm will be
near terrain west and along the eastern state line. An approaching
storm system will bring deteriorating flight conditions to the
area from west to east tonight. Chambers
