Detroit, Michigan – A colder-than-normal weather pattern expected to settle across southern Michigan between Tuesday and Saturday is increasing concern for snow and potential travel disruptions across the region. The developing setup favors sustained cold air, raising the likelihood that any systems moving through during this window could produce accumulating snow.
According to the National Weather Service Climate Prediction Center, southern Michigan is favored for below-normal temperatures during the January 20–24 period, while precipitation probabilities trend above normal at 40–50%. With cold air firmly established, precipitation is more likely to fall as snow, including across metro Detroit where marginal winter events can often bring mixed conditions.
In Detroit and surrounding communities, daytime temperatures are expected to remain suppressed, with overnight lows falling well below freezing. Cold pavement temperatures may allow snow to accumulate quickly and linger, increasing the risk for slick roads and slow travel. Farther west and north, including areas toward Lansing, Jackson, and Flint, confidence is higher that precipitation falls entirely as snow, with limited melting between events.
Major transportation corridors such as I-75, I-94, I-96, and U.S. 23 could become hazardous during snow periods, particularly overnight and during the morning commute. Prolonged cold may also increase the risk of icy conditions even outside of snowfall, as untreated surfaces remain frozen. Utilities and emergency managers are monitoring the potential for increased energy demand as temperatures run well below seasonal norms.
Residents are encouraged to prepare ahead of the Jan 20–24 period by checking heating systems, insulating exposed pipes, and ensuring vehicles are equipped with winter emergency supplies. While significant snow is not guaranteed, the evolving pattern supports the potential for at least one impactful winter weather event.
This cold-driven setup is expected to persist through late week, and confidence may increase as individual systems come into clearer focus. Additional winter weather advisories or alerts could be issued as conditions warrant.
