Showers and thunderstorms will develop across much of southwest Montana today. Thunderstorms capable of producing gusty winds and small hail will begin to impact Butte and Bozeman after 12 pm. Isolated storms are possible for Kalispell and Missoula. Outside of the thunder threat, look for mostly sunny skies with highs in the 80s to low 90s. A similar forecast for Tuesday. Afternoon thunderstorms will develop again with the best location across southwest Montana. Missoula has a chance for weak storms Monday and Tuesday, while Kalispell will largely be left out.
