.DISCUSSION...

Westerly flow aloft will help to maintain breezy conditions
across Little Belts through the day on Saturday, with winds
increasing on an order of magnitude of 5-10 mph each day. Wind
gusts probabilities for 40 mph or greater range from a 15% chance
today, 65% chance on Friday, and 85% chance on Saturday. By Friday
evening Pacific moisture will begin to stream eastward and across
the Northern Rockies, bringing a chance for light snow to the
incident area. Snow chances increase further through the weekend
and into early next week as an active pattern takes hold over much
of the Western US, with a Arctic front moving south and across
Central Montana Saturday evening.
