Wet and heavy snow will fall again across much of southern Montana and northern Wyoming starting today through Friday. Areas west of a line from Roundup to Billings to Sheridan, Wyoming have the best chance for higher snow accumulations.
Accumulations of 3 to 6 inches possible in the lower elevations, with the foothills seeing 4 to 8 inches, with locally higher amounts possible. The mountains could see 10 to 18 inches of snow.
Precipitation will likely start off as rain or a rain/snow mix Wednesday night, changing over to snow by early Thursday morning. Periods of snow will likely last into Friday morning.
Roads will likely become snowpacked and slick during the overnight and morning hours, turning wet and slushy during the daytime as road surface temperatures warm, then re-freeze again during the evenings.
High temperatures will be in the 20s to lower 30s on Thursday, with chilly teens and 20s possible on Friday. Low temperatures Thursday night/Friday morning could be down into the single digits and could even threaten some record lows.
The continued cold and wet weather will be a threat to young livestock.
The weather pattern looks to remain unsettled and cool through the weekend with another storm system potentially bringing another chance for accumulating snow to portions of the area Saturday night and Sunday.
