First Alert 48 Hour Forecast

Scattered showers will continue through Saturday evening and become widespread overnight south of Missoula. Because of this, we will see another round of accumulating snow for passes and the higher valleys. Lows will be ripe for snow and slippery conditions, in the upper 20s and low 30s.

A WINTER WEATHER ADVISORY is in effect from 9 pm Saturday to 3 pm Sunday for Butte, Georgetown Lake, Salmon, Anaconda, Deer Lodge, Lost Trail Pass, Lolo Pass, and Homestake Pass. Georgetown Lake and the passes will see 3 to 6 inches of slushy snow, while valley areas such as Butte will see 1 to 2 inches. A dusting of snow or light accumulation is possible for all high valleys east of Missoula as well as Darby and Sula in the Bitterroot Valley. All of Southwest Montana will have a chance to see some form of snow overnight.

As we warm up on Sunday, showers will diminish and become more scattered. Highs will reach the 40s and 50s.

We will warm up tremendously heading into the new week with temperatures in the middle and upper 70s midweek under sunny skies.
