BOZEMAN – Well above normal temperatures again today for SW Montana, in fact, near record highs east of the divide.
A Canadian cold front is dropping southward along the Rocky mountain front and will continue to dig deeper into Montana this evening. At the same time moisture is streaming in from the SW. As these two collide look for increasing areas of valley rain or snow and accumulating mountain snow this evening into Sunday morning.
There is a slight chance for some pockets of freezing rain after the front passes through early Saturday evening.
Temperatures will be cooler by Sunday but falling closer to normal levels.
Another round of snow will develop Monday evening and could produce locally heavy wet snow across mountains east of the divide. Forecast models show the best chance for heavy wet snow around Big Sky, Cooke City, Island Park, ID and Yellowstone National Park.
