.DISCUSSION...The cold front moving south out of Alberta early this
morning has already begun to cause gusty east to northeast winds
and snow showers east of the Continental Divide near Glacier
National Park. This is expected to continue and intensify
throughout the morning, with the chance for snow existing above
roughly 5000 feet in elevation, including Marias and Logan passes.
Very raw, cold, and windy backcountry conditions will exist during
this time.

This disturbance will continue to move south and east through the
morning and early afternoon hours, impacting down into the Bob
Marshall Wilderness region before exiting completely to the east.
Drier air and sunnier skies will then occur for the rest of the
day, though gusty north-northwest winds will linger through the
evening hours, especially from along I-90 and points south in
western Montana and central Idaho.

Friday morning will likely start out quite chilly as a cool and
dry airmass filters in behind today`s system, which will allow
skies to clear. Many locations have the potential to drop well
below freezing, especially valley locations in northwest Montana
and along the Continental Divide. Those sensitive to below
freezing temperatures (any remaining gardening, exposed hoses,
etc) should take precautions.

Dry northwest flow is expected over the region into early next
week. A slow warming trend will occur, with temperatures reaching
slightly above seasonal normals by the weekend. Winds could become
a bit breezy on Saturday afternoon, with the main impact being
increased chop on area lakes.

Forecast models continue to show a flattening of the flow (turning
more westerly) by mid week. This could open the door for cooling
temperatures, increased winds, and possibly precipitation,
especially across northwest Montana.


.AVIATION...Gusty east to northeast winds will occur this morning
at KGPI with mountain obscurations prevalent as a cold front
crosses the area through about noon today. Thereafter, conditions
should improve greatly, however gusty winds will linger into the
afternoon hours. Elsewhere, fair flying conditions will exist as
most other locations will be free of any impact from the fast-
moving cold front this morning. KBTM, KMSO, and KSMN will likely
encounter gusty north winds this afternoon and evening, but
otherwise...few impacts are expected.
