A WINTER WEATHER ADVISORY is in effect for western Montana until 11am Tuesday. Up to 4 inches of snow accumulation is possible, with most locations receiving less than 2 inches of snow accumulation.

There are going to be some scattered areas of precipitation around tonight and tomorrow as a storm system slowly works its way through our area. This precipitation is going to be in the form of snow in a lot of locations, but some freezing rain and rain is also possible, especially in the warmer plains locations, like Great Falls. This precipitation will then taper off to isolated showers tomorrow night as this storm system leaves our area. We are also going to have mostly cloudy skies tonight and tomorrow and decreasing clouds tomorrow night. There are also going to be areas of fog around tonight and tomorrow, and some of this fog will be dense.

For tonight and tomorrow, light snow accumulations of a coating to an inch or two, and light ice accumulations of a light glaze are possible in locations that do see some snow and/or freezing rain. Slippery road conditions are also expected in some areas tonight and tomorrow due to this new precipitation and due to the precipitation that we saw during the day today, so please be careful when driving and give yourself some extra time to get to where you need to go.

It is also going to be cool tonight and tomorrow as lows tonight are going to range from the upper teens to the low 30s, and highs tomorrow are going to range from the mid 20s to the low 40s.
