There are going to be scattered areas of snow around tonight, especially in central Montana (including around Great Falls, Helena, and Lewistown) and between the Continental Divide and I-15, as a disturbance passes through our area. A little rain is also possible this evening. There are then going to be scattered areas of snow around tomorrow (especially during the afternoon and evening) and tomorrow night (especially before midnight and especially in central Montana and in between the Continental Divide and I-15) as another disturbance passes through our area.

Elsewhere, up to 2 inches of snow accumulation is possible, but most locations will receive less than an inch of snow accumulation. Also, in the mountains, up to a foot of new snow accumulation is possible through Wednesday evening. This snow will create slippery road conditions, so please use caution when driving and give yourself some extra time to get to where you need to go.

Tonight, lows are going to be in the mid to upper teens and low to mid 20s.
