Rain and snow will continue until Sunday
Weather Discussion: Rain and snow will continue to fall across the region throughout the rest of the night and tomorrow morning. Radar shows the movement of moisture from the southeast to the northwest. Upper level basins are thanks to their low pressure and humidity.
Highs today were in the 30s to 40s with lows in the 20s and 30s tonight. As temperatures drop below freezing tonight, snowfall is likely to begin and continue throughout the night. From Cut Bank to Great Falls to along the Rocky Mountain Front, more than 2 inches of snow is possible over the next 24 hours. Higher elevations of the Rocky Mountain Front could see between 8 and 12 inches of snowfall.
A winter weather advisory is in effect for parts of north-central, western and southwestern Montana until 5pm and 6pm on Sunday. Snow accumulation of 2-4 inches is possible at lower elevations and up to 8 inches at higher elevations. The main concern will be morning conditions for roads that are slippery due to snow.
A winter storm watch is in place for parts of the Rocky Mountain Front until 5 p.m. Sunday. Heavy snow is expected with snow accumulations of up to 10 inches. This is in addition to active winds of up to 45 miles per hour in these areas, which may cause low horizontal visibility due to snowfall and slippery roads.
As tomorrow morning’s weather system moves north into Canada, mostly dry conditions and calmer winds are expected to return Sunday night. We expect slightly above average highs Monday and Tuesday in the 40s and drier conditions except for scattered snow showers mostly in higher terrain and along the western portion of the state. An unsettled weather pattern returns mid to late next week with daily chances of rain. Temperatures return to almost normal during this period, with highs in the 20s and 30s.
Saturday night: Rain and snow mix. Cloudy, with a low of 20/30. Wind gusts reach 45 mph along the Rocky Mountain Front, and up to 20 mph elsewhere.
