The weekend will be cloudy, rainy, and snowy for a good majority of Montana, with snow levels dropping close to most lower elevation locations by early Sunday morning.

Through the rest of the evening, temperatures will drop into the 40s with scattered rain showers around the Helena area.

A cold front from the north will move through the state Saturday afternoon and evening. This will lower snow levels and allow for some accumulation in the mountains. The freezing point is expected to lower to about 5-6k feet by Sunday morning, allowing for snow at mountain passes. Some flakes may fly in lower elevations as well, but accumulation is unlikely.

The first freeze for many lower elevations will come on Monday morning behind the storm system. Clear skies will allow for cooler morning temperatures next week.

Expect cold mornings and warming afternoon temperatures early next week under clear to mostly clear skies
