WINTER WEATHER ADVISORY for all other areas of western Montana, including the Missoula, Butte and Kalispell areas.  Snowfall of a trace to 2 inches in the valleys with a mix of rain or just rain and 3 to 8 inches in the mountains.

More Pacific moisture will move across western Montana, and that mean more snow and rain.  We will see rain, drizzle mixing with snow at times around Missoula, with rain and snow in Kalispell and accumulating now in Butte and Bozeman.  Heavy mountain snow will continue, making traveling treacherous at the passes through early Wednesday.  The precipitation will be gradually ending south of I-90 early Wednesday morning and north of I-90 during the afternoon as it lifts north out of the region.  Lows in the upper 20s to lower 30s.  Highs Wednesday in the upper 30s to lower 40s.

Thanksgiving Day will be mild with mostly cloudy skies and highs in the 40s.  There will be a chance of showers just north of Missoula north to the Kalispell area.

Rain and snow will be developing again on Friday.  As arctic air invades the area Friday night and Saturday, the precipitation will become all snow.  Significant snowfall is possible in some areas.  Highs will drop to the 10s and 20s this weekend with lows dropping to the single digits and lower 10s.
