Broadwater and Gallatin.

Saturday night and Sunday morning rain will transition into snow below 4,000 feet. Big Sky Resort could see up to 6″ of fresh snow, Bridger Bowl 10-12″, and further north Whitefish Mountain could also see up to a foot of fresh snow.

However, although all the models do predict snow, there is equal confidence that there will be no snow and more than 6″ of snow will fall! Confidence is high though that areas east of the Continental Divide will encounter some difficult to dangerous winter weather this weekend.
