Strong westerly winds are expected to move over the Northern Rockies on Wednesday. These winds will mix down to the surface, causing gusty conditions. At the moment, the Northern Rockies should experience widespread 30 to 40 mph wind gusts, which includes Flathead Lake along with other area lakes. Expect increased wave activity as a result. The potential exists that parts of southwest Montana, particularly from Deer Lodge to Butte, could experience gusts up to 50 mph.
High chop due to gusty west-southwest winds will occur on Flathead Lake early Wednesday morning and last through the afternoon hours. Sustained winds of 20-30 mph with gusts to 40 mph will be common. Wave heights of 1 to 3 feet should be anticipated during this time period.
Snow levels appear to be around 5000-6000 feet during this active period. Lolo, Lost Trail and Marias Passes have the best shot of receiving accumulating snow through the first part of the work week.
