High pressure will be in control this week which means clear, chilly nights and sunny, mild days in some areas. The exception to this will be the valleys west of the divide where inversions will develop. That means low clouds and fog will develop in those areas, including the Missoula, Flathead and Mission Valleys. The fog may lift during the days, but it was persist in places like the Flathead and Mission Valleys. Highs Tuesday in the upper 30s and 40s.
Dry skies and calm weather will stick around through Friday. We are tracking a weak storm system will move through the region this weekend. Some models indicate there will be a chance of rain and snow while others do not. At this point we are leaning toward the latter scenario.
