Strong westerly winds are expected to move over the Northern Rockies on Wednesday. These winds could mix down to the surface causing windy to breezy conditions. At the moment, the Northern Rockies should experience widespread 30 to 40 mph wind gusts. The potential exists that parts of southwest Montana, particularly from Deer Lodge to Butte, could experience gusts up to 50 mph.
A strong low pressure system off the Pacific Northwest coast will be pushing in ample moisture into the Northern Rockies causing widespread precipitation with many areas receiving significant moisture totals. The most intense precipitation appears to be Tuesday night.
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.
