.DISCUSSION...The last of this most recent low pressure system`s
precipitation is on its way out, with only a few showers remaining
along the Continental Divide this morning. By this afternoon
though, most locations should begin to dry up, with a fairly
decent afternoon and evening in store. One feature that will
definitely be noticed throughout the day today will be gusty west
winds, which will develop in the early afternoon hours and persist
through the late evening and overnight hours. This may be of most
concern to those who will be boating this evening, as water could
become quite choppy.

The next impact period will be late tonight into Thursday morning
for locations near Glacier National Park and the Bob Marshall
Wilderness. A quick-moving disturbance with plenty of moisture and
cold air will slide down out of Alberta and bring a chance for
snowfall to elevations down to roughly 5500 feet. A winter
weather advisory may be needed later to address potential impacts
to those recreating/hunting in the backcountry, as conditions
could be very raw, cold, and wet during this time period. For
elevations below 5500 feet, rainfall is expected. Precipitation
should be out of the area by later in the day Thursday.

On Friday, a ridge of high pressure building along the west coast
begins to strengthen into the Northern Rockies. This should lead
to a generally pleasant day with sunny skies and warming
temperatures. The morning will likely start out quite chilly with
temperatures dropping to freezing or even below in many valley
locations. This could also allow for some patchy fog to start the

Saturday, the ridge of high pressure flattens slightly. The main
result will be for an increase in gusty winds, which could again
cause impacts to boaters on area lakes due to choppy conditions.
Sunday into early next week shows the ridge strengthening,
allowing warming temperature to a few degrees above normal for
this time of year.


.AVIATION...A few lingering showers may exist this morning, but
precipitation is, on the whole, on its way out of the area for
today. Gusty west winds will be the main feature to look out for,
with the strongest period for winds occurring between 01/2000Z and
02/0600Z. Gusts could be quite strong at times. After 02/0600Z, a
weather disturbance is expected to slide down along the Divide,
bringing snow showers to higher terrain and rainfall to KGPI and
KBTM through the early Thursday morning hours. Mountain
obscurations will be prevalent.
