There is going to be some light snow around tonight, generally in central Montana, including around Great Falls, Helena, and Lewistown, and light snow accumulations of up to an inch or two are possible. We are also going to have overcast skies tonight with a few areas of fog around. It is also going to be cold tonight in north-central Montana as lows are going to be in the -0s and 0s. Around Helena, lows tonight are going to be in the teens and low to mid 20s.
A significant snowstorm is then going to impact our area tomorrow and Saturday. As we go through tomorrow, snow will develop from southwest to northeast. Around Helena, snow is likely tomorrow morning, but the snow will taper off from southwest to northeast during the afternoon and evening. In north-central Montana, locations around and west of I-15 and in southern portions of north-central Montana, including around Great Falls and Lewistown, will see snow begin to develop during the mid to late morning. This snow will then overspread the rest of north-central Montana during the afternoon and evening. For Havre and points eastward, snow will arrive around or after sunset tomorrow.
Widespread snow is then likely tomorrow night in north-central Montana and there are going to be areas of snow around the Helena area tomorrow night. Some of the snow that falls tomorrow and tomorrow night will be heavy at times. Light to moderate snow will then continue to fall on Saturday, especially in locations east of I-15, but this snow will gradually taper off from west to east as the day goes on.
Check the Montana Department of Transportation website before you hit the road to find out which roads are snow-covered, which ones have ice and/or slush, and if any roads are closed. You can also check MDT cameras from across the state by clicking here.
This snowstorm will drop a significant amount of snow. A widespread 3-12” of snow is expected in central and north-central Montana from this evening through Saturday evening, with most locations receiving 5-10” of snow. In the mountains, 6-18” of snow is expected through Saturday evening. Due to this snow, difficult travel conditions are expected tomorrow and Saturday (especially tomorrow afternoon through Saturday morning), so please use extreme caution when driving and consider delaying your travel if possible. Also, give yourself plenty of extra time to get to where you need to go.
It is also going to continue to be cold tomorrow and Saturday in north-central Montana as highs are going to be in the single digits, teens, with lows in the -0s, 0s, and low 10s. Around Helena, highs tomorrow are going to be in the mid to upper teens and low to mid 20s in most locations and highs on Saturday are going to be in the upper 20s and low to mid 30s in most locations. It is also going to be breezy in some areas east of I-15 tomorrow as sustained wind speeds are going to be between 10 and 20 mph.

On Sunday, we are going to have mostly cloudy skies with a few snow showers around in north-central Montana and scattered snow around Helena. Snow is then likely around Helena on Monday and there is going to be some scattered snow around in north-central Montana on Monday, generally around and west of I-15 as well as along the MT 200 corridor.
