.DISCUSSION...


KEY MESSAGES:

-  Gusty north to north east winds later today into Thursday bring
   raw backcountry conditions and choppy water on area lakes

Temperatures will be much cooler today compared to recent days
behind the cold front that moved through the Northern Rockies
Wednesday. Afternoon highs are likely to top out around 5 to 10
degrees below normal for most locations. Satellite and radar
images show the front is still making its through southwest
Montana this morning, and will continue to produce light to
moderate snowfall along the Continental Divide through mid
morning. Continuous snowfall will become more showery in nature
this afternoon across most of western Montana and north-central
Idaho.

A brief return to high pressure is expected Friday into early
Saturday, though it appears short-lived. Forecast models are
showing another Pacific cold front moving across the Northern
Rockies late Saturday into Sunday, that will bring more mountain
snowfall, and cooler, breezy conditions. This round of active
weather isn`t expected to be as cold as the more recent event, so
valleys will see mostly rain, perhaps a mix of rain and snow.

An active weather pattern will remain over the region through the
first half off next week, then a potential drying and warming
trend returning to round out the week.
