BOZEMAN – Active weather pattern returns to Montana Saturday evening through Sunday evening with an Alberta Clipper dropping through the state.
Norther, central, and eastern counties of Montana will see the lion share of the snow and wind with difficult to impossible travel hazards Saturday night through Sunday evening. SW Montana will get a glancing blow of this cold front late Sunday morning through early Sunday evening.
Greatest concerns for SW Montana will be rain changing to snow producing wet and icy roads. Freezing rain is possible but should be on the patchy side. Regardless, wintry travel is likely especially between Butte and Bozeman with heavier snow bands between Bozeman and Billings including Bozeman pass.
This front will quickly drop through Montana and will be gone by Sunday evening with clearing skies by Monday morning could produce dense fog for your Monday commute.
WINTER WEATHER HIGHLIGHTS
The National Weather Service has a WINTER WEATHER ADVISORY up tonight through Sunday evening across most of Montana east of the divide. Light to moderate snow accumulations along with a rapid temperature drop, pockets of freezing rain, will combine to produce hazardous travel Sunday.
The National Weather Service issued a WINTER WEATHER ADVISORY for Gallatin County from 5 am to midnight Sunday.
Valley snow should be light around 1”-3” with Bozeman Pass possibly picking up 3”-6” of snow. Freezing drizzle is possible which will leave an icy glaze on roadways. Rain changing to snow will also produce icy road conditions.
WINTER STORM WARNING

There is still some uncertainty on how this cold front will impact travel on I-90 between Butte and Missoula. There is potential for snow banding to occur with moderate short bursts of snow. Rain changing to snow is also possible along with a slight chance for freezing drizzle.
