Moisture will combine with a Canadian cold front late in the day Thursday through Friday. Daytime highs will be in the 40s, but the front will push lows into the 20s overnight. The combination of rain and snow, gusty winds and blowing snow, will create travel concerns Thursday night into Friday morning. Snowfall of 5 to 10 inches in the the mountains, including MacDonald and Marias passes. The Flathead Valley may see 2 to 4 inches of snow. Elsewhere, less than 2 inches of snow are expected.

Snow levels will begin to increase Friday as the arctic air retreats. Daytime highs will be in the mid to low 40s.

FLOODING CONCERNS: Rainfall Thursday through the weekend will be moderate to heavy, with generally a half to 2 inches with locally up to 3 in some areas. Runoff due to rain and snowmelt will lead to a noticeable rise in the streams and rivers.
