Glasgow, Mont. – Frost glitters across the high plains this morning as the sun rises into a clear, icy-blue sky. The stillness won’t last — by midweek, winds will begin to stir again across Valley County, adding a sharp edge to otherwise sunny afternoons. The region remains locked in a classic late-October pattern: brisk mornings, bright skies, and wide temperature swings from dawn to dusk.
According to the National Weather Service in Glasgow, highs today will reach the lower 50s before dropping back into the 20s tonight. Winds will strengthen on Wednesday, gusting 25 to 30 mph out of the southeast, particularly across open stretches of U.S. Highway 2 and near Fort Peck Lake. Drivers hauling trailers or working in exposed areas should prepare for crosswinds and blowing dust during the afternoon.
The midweek chill holds through Thursday before a warming trend begins into Halloween weekend. Friday looks dry and mostly sunny, with highs near 47°F and calm evening conditions — ideal for trick-or-treating or local fall events. By Saturday, temperatures will rebound into the low 60s under partly sunny skies, offering a pleasant window for outdoor cleanup or final harvest work before November’s next cooldown.
No snow is on the immediate horizon, but models hint at a cooler, unsettled stretch returning early next week — typical for eastern Montana’s swift shift into winter. For now, the clear skies and crisp air mark a brief calm before that next seasonal turn. After all, November’s chill never stays far from the Hi-Line.
