A WINTER WEATHER ADVISORY continues this evening and through Friday for much of Montana. Heavy snow is moving up through the state after a mostly sunny day. The weather will turn very quickly once the snow starts. Roads are quickly getting coated. Visibility will be reduced because of the heavy snow. Please be careful Valentine’s Day evening. Snow will continue Thursday night into Friday. Friday will be mostly cloudy with areas of snow moving through the state. Highs will remain cold up on the Hi-Line but warm up to the 30s in southern and central Montana. Saturday will be a mostly cloudy day with snow showers increasing late in the day as another surge of arctic air moves south through the state. Sunday will be much colder with snow in the morning. Arctic high pressure will settle over the state Sunday night, and most of Montana will chill down to between -15 and -40 once again. Monday is Presidents’ Day and it will start out dangerously cold but sunshine will prevail for the holiday. This unusually cold and snowy pattern will continue through the rest of the month (another 2 weeks) at least.
