Snow bands will form across the areas in orange and red on the map this evening and tomorrow morning. They are expected to reach peak intensity Wednesday morning, when snow squall conditions are possible (15-25% chance) mainly in Lemhi County, ID, which is colored read on the map.
Gusty west winds are moving in Wednesday and lasting through Friday. Valley locations will see widespread gusts from 25 to 35 mph, which is enough to blow around unsecured trash cans, recycling bins, and lightweight patio furniture. If you are in Southwest Montana, expect stronger gusts up to 45 mph. For those driving high-profile vehicles or towing trailers, prepare for dangerous crosswinds over the mountain passes and along the Divide, where gusts could peak between 50 and 70 mph.
