MISSOULA — High pressure will lead to a very nice day Friday. Some patchy fog will be possible for the valleys during the morning. Other than that, we will see sunshine and high temperatures in the 50's with even a few 60's possible for the Bitterroot Valley.
Clouds will be increasing Saturday in front of our next system. Expect dry conditions through mid afternoon with scattered rain showers possible by the late afternoon and evening. Highs on Saturday will top out in the low to mid 50's.
Starting late Saturday night, a cold front will drop south out of Canada and move from east to west across the divide. The front looks to reach Marias Pass Saturday night then move into the Flathead Valley by Sunday morning.
This does not look to be a major snow event, especially for locations west of the Divide. Most of the impacts from snow will be seen along and east of the Continental Divide. Marias, MacDonald and Homestake Passes could see 4"-to-6" of snow.
The biggest impacts from snow for locations west of the Divide look to be from around Seeley Lake then south and east towards Garrison Junction where 2"-to-4" will be possible. All other locations may see scattered rain/snow showers with very little or no snow accumulation expected.
The biggest impacts with this front will be the strong northeast winds, especially in northwest Montana. Areas from the Flathead Valley and east could see winds gusts around 45-to-50 mph Saturday night into Sunday morning.
Difficult travel due to snow and blowing snow, especially along the Divide can be expected. High temperatures will drop from the 50's Saturday into the 30's and 40's Sunday.
Looking at next week, dry conditions are expected Monday and Tuesday with highs in the 30's and 40's Monday then 40's and 50's Tuesday.
