.DISCUSSION...

Warm high pressure currently over the Northern Rockies will
gradually transition to southwesterly flow aloft through Friday.
Afternoon temperatures will continue be quite warm for late
September. Also, high level moisture and cloud cover will be
increasing during this time. Showers and thunderstorms will begin
to appear on Thursday afternoon, with more widespread development
on Friday afternoon. Anticipate gusty winds to exist in the
presence of any thunderstorms that develop.

As a trough of low pressure approaches from the west, a cold
front will push through the Northern Rockies on Saturday. The
front will be relatively slow-moving, so strong winds are not
expected. There is a good chance most places will see a wetting
rain from this front, with the current forecast calling for a
tenth to a quarter of an inch of valley rain over the 24 hour
period.

Behind the front, colder air will move in Sunday, leading to
unseasonably cool temperatures with highs in the 50s and 60s for
most valleys. Expect abundant cloud cover with occasional showers.
These conditions will persist through the first half of next
week.

.AVIATION...

Some gusty easterly winds will impact air travel across the
Northern Rockies through 29/0000Z, however much of this wind will
be confined to near KGPI and along the Continental Divide. Winds
will gust to 25 kts at times. No other weather-related impacts are
expected today.
