Area Forecast Discussion

.SHORT TERM...valid for Tue and Wed...

High pressure ridging will be over the forecast area through
Wednesday. The jet stream will be positioned well north of the
area across southern Canada. As a result, clear skies will prevail
tonight with sunny to mostly sunny skies expected Tuesday and
Wednesday. A weak cold front will move south across the forecast
area Tuesday evening/night. This will allow winds to switch to the
northwest to north Tuesday night then easterly for Wednesday. The
front looks to be dry so we are not expecting any shower activity
to be associated with it. Temperatures Tuesday will be well above
normal with readings in the lower to middle 80s across the lower
elevations. Temperatures will be cooler Wednesday but still above
normal with most areas seeing readings in the lower to middle 70s.

.LONG TERM...valid for Thu...Fri...Sat...Sun...Mon...

Little in the way of changes for the extended period...as models
remain in reasonably good agreement on longwave trough slowly
sliding eastward throughout the period.  Expect to see daytime
temperatures above seasonal average with highs in the 70s into
Saturday. Cooler weather again to end the extended period.

Generally dry conditions will prevail in the lower elevations Thursday
and Friday. Southwest flow begins to push into the region from the
west on Thu...first bringing a chance of showers and thunderstorms
to the mountains Thu through Sat morning. As the trough continues
to propagate eastward, shower/thunderstorm chances expand eastward
across much of southern MT/north central WY beginning Sat
afternoon. The region remains in cyclonic flow with trough axis
west of the CWA until late Tue. At this time it appears waves of
showers/t-storms should move through the area late Sat through
Tue...but appreciable uncertainty exists in timing individual
waves and rain chances. RMS/Hooley
