Valley rain and mountain snow into Sunday morning
A Pacific storm will move across Montana Saturday night, producing rain in the valleys and snow in the mountains. Snow levels will drop to between 4000 and 5000 feet overnight as lows approach freezing in the higher elevations. However, warm ground and road temperatures overnight should limit snow accumulations over passes. Some slushy or icy spots will still be possible in the morning however in pass areas.
Showers will move from west to east, impacting Missoula and Kalispell the most during the evening and having the most impact after midnight around Butte and Bozeman. After sunrise on Sunday expect lingering mountain snow showers, particularly west of the divide. A few showers will be possible in the morning in our western valleys before calmer conditions late morning and into the afternoon. Highs will be warm again around the region, in the 40s and 50s.
More rain arrives by Monday afternoon and will linger into Tuesday. The warmer temperatures will continue. This means areas that saw considerable snowfall last week such as Libby and Kalispell should keep an eye on low-lying areas for minor flooding, standing water on area roads, and rock slides in steep areas this week.
With upper 40s to mid 50s for highs almost all week our snow chances will be slim to none until Thursday. An overnight cold front will bring back the possibility of a mix of rain and snow before we quickly warm up again Friday and into next weekend.
Don't forget to spring forward as Daylight Saving Time begins on Sunday. Sunrise will now happen just before 8 a.m.
