Current Weather

Weather Concerns

Gusty winds and rain will return this afternoon. The mountains across northwest Montana as well as the Bitterroot Mountains will feel the brunt of the moisture with up to an inch of rain expected. High pressure builds by Monday to bring fog, frost and near freezing temperatures to start. A gradual warming and drying trend are anticipated next week as a large ridge builds over the Pacific Northwest.
