A Winter Weather Advisory remains in effect until 11 PM MST this evening.
A Pacific weather system will bring numerous snow showers to southwest Montana today and tonight with the heaviest snow showers occurring this afternoon and evening in Madison and Gallatin counties. Total snow accumulations of 1 to 3 inches are expected in the lower valleys... including the Bozeman and Ennis areas with 3 to 5 inches in the higher valleys including the West Yellowstone area. Highest amounts will occur above 7000 feet where 5 to 9 inches are expected. The snow showers are expected to diminish by late this evening.
Southerly winds of 10 to 20 mph with occasional gusts to 30 mph will also develop through south to north oriented valleys by afternoon... reducing visibilities at times in blowing snow during the afternoon. Winds will become more westerly during the evening... which may reduce visibilities at times in blowing snow in more west to east oriented valleys.
Precautionary/preparedness actions...
A Winter Weather Advisory for snow means that periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities... and use caution while driving.
