The Montana plains lie frozen this morning, wrapped in bitter Arctic air that cuts sharper than the wind itself. Across Glasgow and the Hi-Line, headlights glint off snow crusts as steam rises from chimneys into a pale, frigid dawn. It’s a dangerous cold — the kind that bites through gloves and burns exposed skin within minutes.
The National Weather Service in Glasgow has issued a Cold Weather Advisory for much of northeastern Montana, including Phillips, Valley, Roosevelt, Daniels, and Sheridan counties. The advisory remains in effect until 10 a.m. Monday, with wind chills as low as -31°F expected through the period.
At these temperatures, frostbite can occur in less than 20 minutes on exposed skin. Residents are urged to limit outdoor activity, wear multiple layers, and ensure pets and livestock have shelter, food, and access to unfrozen water. Even light winds — 5 to 10 mph — will push apparent temperatures to dangerous levels across the Missouri River Basin and northern prairies.
While skies will turn partly sunny Sunday afternoon, the cold holds firm through midweek. Highs may briefly reach the teens Monday, but another push of Arctic air will return by Tuesday night. A 30% chance of snow Tuesday could add slickness to already frozen roads, followed by continued subzero wind chills.
By late week, highs slowly climb near 30°F, though conditions will remain well below normal for early December. Long-range models suggest the cold may linger into the second week of the month — the strongest signal yet that winter has locked in across the Northern Plains.
Five-Day Outlook (Glasgow, MT):
- Monday: Mostly cloudy, high 16°F, low 4°F.
- Tuesday: 30% snow chance, high 33°F, low 7°F.
- Wednesday: 10% snow chance, high 31°F, low 13°F.
- Thursday: Mostly cloudy, high 35°F, low 20°F.
- Friday: 40% snow/freeze mix, high 35°F.
