GLASGOW, Mont. – The air hangs crisp and still over the Hi-Line this morning, the ground glistening with patches of freezing fog under a pale sunrise. It’s a calm start now, but the next system on the horizon could bring a quick return to winter-like conditions by early next week.
The National Weather Service in Glasgow reports that today and Saturday will stay mostly sunny and mild, with highs in the upper 40s to low 50s — a brief stretch of late-fall calm for eastern Montana. Drivers this morning should still watch for slick spots where fog has frozen on roads, particularly across U.S. Highway 2 and Montana Route 24, as visibility may dip briefly through mid-morning.
A stronger weather shift arrives late Monday into Tuesday, when a Pacific disturbance brings rain changing to snow as temperatures tumble back below freezing. Confidence remains moderate, but forecasters expect light accumulations of up to 1 inch near Glasgow and heavier bursts over higher terrain to the west. Gusty northwest winds up to 35 mph could make travel briefly tricky, especially for high-profile vehicles.
By Tuesday afternoon, colder, drier air will settle in — with highs near 30°F and lows dipping into the teens, marking a clear transition to winter air just ahead of the Thanksgiving travel rush.
Across the broader Northern Plains, forecasters are watching a potential pattern shift late next week that could unleash heavier snow from the Rockies into the Midwest between Nov. 25 and Dec. 3. While Glasgow looks quiet by Thanksgiving Day, colder-than-normal temperatures will likely hold through the holiday.
For now, Montanans should savor the sunshine — winter’s next move may already be taking shape to the west.
