WEATHER DISCUSSION: Several disturbances bring light, accumulating snow showers to the region this week. The first round materializes late Saturday night into Sunday morning. Accumulations should stay below an inch, with the greatest impact east of Great Falls. The second round develops late Sunday night into Monday morning. The greatest impact is going to be confined to northern slopes of the Little Belts and Snowy mountain ranges where 2-4 inches of snow accumulations. Elsewhere, accumulations should stay beneath an inch. The third, and most widespread round, will accompany the next round of arctic air.

High pressure remains centered near the Pacific Northwest coast. It is expected to push further east throughout the next 24-48 hours. This will continue to allow for valley fog/freezing fog and colder daytime high temperatures in valley locations. Elsewhere, high pressure allows temperatures to climb into the 30s for the first half of the week. An arctic cold front moves through late Wednesday night into Thursday. Blowing snow, additional snow accumulation and well below normal temperatures are expected to make a return to the region. Daytime highs will return to the single digits and teens, while overnight lows likely fall below zero once again.
