Montana — Frost clings to grass and rooftops this morning across northeast Montana, while a fast warm-up is already underway.
According to the National Weather Service, temperatures started near 33 degrees early this morning in Glasgow and will rise sharply to around 70 degrees this afternoon.
This is part of a broader spring transition across the northern Plains, where clear skies overnight allow rapid cooling before strong daytime heating takes over.
The most immediate impact window continues through 9 a.m., when patchy frost and isolated slick spots may linger on bridges and untreated rural roads. Drivers along US-2 and MT-24 could encounter brief icy patches in shaded areas and low-lying river valleys near the Milk River.
Conditions improve quickly by late morning. Sunshine warms pavement and visibility remains excellent, supporting smooth travel through Glasgow, Fort Peck, Nashua, and Wolf Point.
The rapid temperature swing also brings agricultural concerns. Early-season crops and backyard gardens may see light frost damage this morning before recovering in warmer afternoon air.
By tonight, temperatures fall again into the upper 30s, bringing another localized frost risk in sheltered drainage areas and open fields.
The weekend delivers stable spring weather. Highs reach the upper 60s Saturday and low 70s Sunday, with increasing northwest winds that could gust near 25 mph, especially across open prairie and along exposed highways.
Meteorologists are now tracking a cooler shift early next week. Highs drop into the low 60s Monday, then mid-50s Tuesday as a weak system brings a slight chance of showers. No severe storms are expected, but brief wet roads and gusty winds could impact travel.
Five-Day Outlook for Glasgow:
Saturday: Partly sunny, high 68
Sunday: Mostly sunny, high 72
Monday: Partly sunny, high 61
Tuesday: Slight chance showers, high 56
Wednesday: Sunny, high 64
