UPDATE: The National Weather Service issued a WINTER WEATHER ADVISORY for Madison, Gallatin, Jefferson, Broadwater, and Meagher counties from 11 am Thursday to 8 am Friday morning.

Snow accumulations: 1"-3" or more is possible.


BOZEMAN – A stream of Pacific moisture will push through Montana from the west at the same time colder air is digging into Montana from Canada.

This will produce widespread snow Thursday afternoon through Friday morning. Once the snow ends colder temperatures will settle in for the weekend.

Widespread snow for valleys and mountain passes is likely Thursday afternoon and evening. This will impact your Thursday evening commute and Friday morning commute. Plan on icy road conditions at all levels.

Most valleys could see 1”-4”, some a little more and others less, which should produce icy roads. Higher mountain passes could see 2”-6” of snow.


The National Weather Service continues a WIND ADVISORY and a HIGH WIND WARNING for the Livingston-Big Timber-Harlowton areas through 6 pm Wednesday.

Peak wind gusts to 60 mph are possible.
