An early autumn storm system will continue to spread across central Montana tonight. Expect widespread rain over most of southwest and north central Montana this evening and Sunday. A cold front across north central Montana will usher in cooler air overnight as it drops southward. As the cold air moves into the region tonight… the rain will change to snow for elevations above 5500 feet. The snow could be heavy at times in the mountains late tonight and on Sunday morning… with visibilities less than one half mile at times. The snow will begin to decrease in intensity on Sunday afternoon. Total snow accumulations will generally range from 4 to 8 inches for elevations above 5500 feet… with amounts around 12 inches near some of the higher mountains.
Some mountain ranges that will likely receive the heaviest snowfall include… the Highwood… Little Belt… and Big Snowy Mountains. A Snow Advisory means that periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities… and use caution while driving.
