.DISCUSSION...High pressure remains in firm control over the
region with some mid level clouds moving through the region. Even
with the cloud cover temperatures have reached the mid and upper
60s, about 5-10 degrees above normal. This pattern will continue
through Wednesday.

Thursday a weak and very dry, cool airmass, will move south from
Alberta and brush the continental divide, shunting the ridge to
the west. There will be enough of a pressure gradient to produce
some breezy easterly winds and cooler temperatures to near normal
Thursday and Thursday night across western Montana.

Friday and much of Saturday the strong ridge rebuilds over the
region and brings a return to a warm and gorgeous autumn weather.
Record high temperatures Saturday are in the mid 70s. It`s
possible we reach the 70s but such warm temperatures this time of
year are very dependent cloud cover. Currently it looks like
clouds will increase Saturday afternoon in Central Idaho and
Saturday evening in western Montana ahead of a weather disturbance
which breaks down the ridge.

Noticeable change occurs late Saturday with this weather
disturbance. Expect an increase in the potential Saturday evening
through Sunday.

Early next week confidence is high for things to be continued
unsettled with just below seasonal temperatures in the 50s along with
a potential for showers.


.AVIATION...VFR conditions will continue across the region the
next few days with only some high and mid level clouds at times.
Breezy afternoon winds will dissipate this evening with the loss
of daytime heating.
