BILLINGS — TGIF!
Well, we've enjoyed a milder than normal winter so far, but now comes a dose of reality!
A Winter Storm Warning is effect for most of the viewing area as a big blast of arctic air out of Canada rumbles toward the state. In fact, we'll hit our high temperatures this morning which will remain steady or slowly fall during the day. The arctic air will interact with a steady flow of moisture coming out of the northwest to produce snow, with periods of heavy snow, through the weekend.
Here in Billings, the snow should be falling around the area when most wake up this morning and will continue through the day. This will make the afternoon commute miserable. Traveling conditions will not be good. Up to 3" accumulation possible by this evening.
There could be a bit of a break on Saturday, but another reinforcing shot of cold air coming in by Saturday night will crank up the snow machine again. From Friday through Sunday, looking at snowfall accumulations of 1-2 feet over the mountains, 6-12 inches along the foothills and out into the plains. Billings is staring down upwards of 8-12 inches.
In terms of temperature, weekend highs will be in the teens on Saturday and single digits on Sunday. Overnight lows will drop below zero. Wind chills will be well below zero. For now, it looks like this cold blast will hang on into late next week. Beyond that, uncertainty remains.
