A WINTER STORM WARNING continues for much of Montana through Monday night into Tuesday morning for heavy snow, dangerously cold temperatures and wind chills, and extremely difficult travel. A WINTER WEATHER ADVISORY continues for the Hi-Line through Monday night into Tuesday morning where lighter snow is falling.
The biggest and worst snowstorm of this winter is blanketing the state with heavy snow along with very cold temperatures. Some areas in the state have already exceeded more than 12″, and wind chill values have been as cold as -45 on some of the mountain passes. These conditions are dangerous and could be life-threatening. Please use extreme caution outside whether you’re walking or traveling.
Snow will come to an end through the morning hours on Tuesday, but the day will remain cloudy and cold. South of the Capital there will be a little snow continuing through Tuesday afternoon. The next round of snow will spread through Montana on Wednesday afternoon and evening. Another accumulation of a few inches is likely. This round of snow will wind down through Wednesday night into Thursday morning. However, another round of snow will develop later on Thursday. Temperatures will moderate some by Thursday with highs in the 10s, but Friday temperatures will free-fall as another cold front comes down from Canada. Friday will be a snowy day with falling temperatures and dangerously cold wind chills. Several more inches are likely to accumulate on Friday. Finally the snow will push south out of Montana by Saturday as arctic high pressure brings in drier air but temperatures will be extremely cold this weekend. While sunshine will be widespread with clear skies, highs will only be in the -0s and lows will range between -20 to -40. So much for the first weekend of March.
Please be careful out there.
