... Winter Weather Advisory in effect from 11 am this morning to 11 PM MST this evening...
The National Weather Service in Great Falls has issued a Winter Weather Advisory for snow... which is in effect from 11 am this morning to 11 PM MST this evening.
A Pacific weather system will bring numerous snow showers to southwest Montana today and tonight. The heaviest snow showers will occur this afternoon and evening in Madison and Gallatin counties. Total snow accumulations of 2 to 4 inches are expected in the valleys through this period... while 5 to 9 inches are expected in the mountains. The snow showers are expected to diminish through the later evening hours.
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.
For specific Road and travel conditions in Montana... dial 5 1 1.
