A WIND CHILL ADVISORY is in effect for most of central and north-central Montana into Wednesday for wind chills as cold as -40. A WIND CHILL WARNING is in effect for far northeast Montana for wind chills as low as -50.
The biggest snowstorm of winter blanketed much of the state with significant snow. Areas from Great Falls through Helena, Butte to Bozeman, and Hamilton to Missoula had upwards of a foot of snow if not more. Anaconda had nearly 30″! Snow will move back through much of the area on Wednesday accumulating generally 1-3″, with up to 4-5″ in the mountains. It’s a quick hitting system that moves out Wednesday night. However another area of low pressure will move in on Thursday with more widespread snow again generally accumulating 2-4″, with up to 6″ in the mountains. Thursday’s temperatures will modify all the way up into the 10s and 20s. Friday will turn nasty again as snow moves through with falling temperatures and increasing wind. Snow will accumulate another few inches, but temperatures and wind chills will become dangerously cold. Arctic air will move back into the state through Friday and into the weekend. Most of the snow will come to an end through Saturday morning as high pressure dries up the moisture. Skies will become sunny for some on Saturday, but widespread sunny skies will prevail on Sunday. However, temperatures will be brutally cold for the first weekend of March. Highs will range from -10 to 0, with lows -20 to -40. For some towns, the coldest night of winter could occur this weekend. Afterwards, a change in the weather pattern is likely around March 5th, which would mean warmer temperatures close to average.
Have a great day.
