Detroit, Michigan – Arctic air is expected to remain firmly entrenched across southern Michigan from Jan. 24 through Jan. 30, bringing a prolonged stretch of below-normal temperatures and reinforcing mid-winter conditions across the region.
According to the National Weather Service Climate Prediction Center, southern Michigan falls within a roughly 70 percent probability zone for below-normal temperatures during the Jan. 24–30 period. Confidence remains elevated that cold air will dominate with few opportunities for sustained warming before the end of the month.
Across southeast Michigan, including Detroit, Ann Arbor, and the I-94 corridor, daytime highs are expected to remain well below late-January averages, with overnight lows frequently dropping into the teens and single digits. Persistent cold will allow icy conditions to linger on bridges, overpasses, and untreated roads, particularly during morning and nighttime hours.
In south-central and southwestern Michigan, including Lansing, Jackson, and Kalamazoo, temperatures are also expected to stay below normal throughout the Jan. 24–30 window. Near Lake Michigan, colder northwest flow may occasionally support lake-enhanced snow, adding to travel concerns along Interstate 196 and U.S. Route 131.
The Michigan Department of Transportation urges drivers to remain cautious during early morning and overnight travel when refreezing is most likely. Residents are encouraged to protect exposed pipes, limit prolonged outdoor exposure, and check on vulnerable neighbors and pets.
The Arctic pattern shows little indication of breaking before the end of the month, and additional cold-related advisories may be issued as confidence remains high in sustained below-normal temperatures across southern Michigan through Jan. 30.
