GLASGOW, Mont. – The predawn air feels razor-sharp this morning across the Hi-Line, with frost shimmering under a pale, still sky. Temperatures dipped into the 20s across Valley County, marking one of the coldest starts yet this fall. But the chill won’t last long — a strong warm-up is on the way, with highs climbing nearly 40 degrees above this morning’s lows by the weekend.
According to the National Weather Service in Glasgow, southeast winds will develop through Tuesday afternoon as a broad ridge of high pressure builds over eastern Montana. After this morning’s biting cold, sunshine dominates the week, driving steady daytime warming. Highs will rise from the upper 50s Tuesday to near 70°F by Friday and Saturday. Nights remain cold but not as harsh, with lows holding near the freezing mark.
Farmers and ranchers should take advantage of the midweek stability for late harvest and livestock prep. Though frost continues early each morning through Thursday, the overall pattern looks favorable for drying fields and finishing outdoor maintenance before the next system arrives.
Models hint at a weak trough brushing northern Montana late Sunday, possibly bringing clouds and a light chance of rain — or even a few snowflakes at higher elevations. Winds could gust near 25 mph as that front passes, signaling another transition toward cooler air next week. For now, Glasgow gets a brief stretch of classic Montana fall — crisp dawns, warm afternoons, and calm, clear skies before winter makes its next move.
