Winter Weather Advisory Friday; Much Colder Weekend Ahead
A strong autumn storm will move through southwest Montana Friday. A Winter Weather Advisory is in effect from Noon Friday through Midnight Friday Night for the Gallatin and Madison County Mountains and Centennial Mountains. Snow is expected to develop Friday afternoon as temperatures fall, with up to 8 inches of accumulation possible during the day Friday in the mountains, followed by additional moderate accumulations Friday night. Mountain passes could become snow-covered with reduced visibility and gusty winds.
Snow levels will fall rapidly Friday, potentially reaching some valley floors by evening. Most lower elevations should see primarily rain before any late-day changeover, while the heaviest snowfall remains focused above 4,500 feet. Temperatures turn sharply colder behind the front, with dry but chilly weather returning for the weekend.
