GLASGOW, Mont. – A frigid Halloween morning greets the Hi-Line under a blanket of quiet stars, the air sharp enough to see each breath rise. Frost clings to pickup roofs and fence lines, but the chill will lift soon — a brief calm before a dramatic shift in the wind.
According to the National Weather Service in Glasgow, Friday will bring gradual clearing and sunshine as temperatures climb into the low 40s. Saturday turns noticeably milder, with highs near 68°F and light southeast breezes. However, this calm stretch will end quickly as a powerful system sweeps into the northern Plains late Saturday night into Sunday.
Winds will strengthen sharply Sunday morning, gusting 40 to 45 mph at times across Valley, Phillips, and McCone counties. Blowing dust and reduced visibility could affect travel along U.S. 2 and Highway 24. Outdoor decorations and loose items should be secured before the front arrives. While skies stay mostly sunny, cooler air and wind chills will make Sunday feel far less comfortable than Saturday’s warmth.
By Monday, conditions settle again with mostly sunny skies and highs near 54°F — a temporary reprieve before another potential cool front arrives midweek.
No snow is expected this weekend, but colder air over the northern Rockies early next week could signal the season’s next transition. Models hint at increasing moisture chances for mid-November, suggesting the region’s first widespread snow event may not be far behind.
Daylight Saving Time ends at 2 a.m. Sunday, giving residents one extra hour to brace for the gusty shift.
