Madison, Wisconsin – A colder-than-normal weather pattern expected to settle across Wisconsin between Tuesday and Saturday is increasing concern for snow and travel disruptions, particularly across south-central and western parts of the state. The developing setup favors sustained cold air, increasing the likelihood that any systems moving through during this window could bring accumulating snow.
According to the National Weather Service Climate Prediction Center, Wisconsin 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, raising the potential for impactful winter weather across inland portions of the state.
In Madison and surrounding south-central Wisconsin, daytime temperatures are expected to remain suppressed, with overnight lows well below freezing. Cold ground and pavement temperatures may allow snow to accumulate efficiently and linger between events, increasing the risk of slick roads. Farther west, including communities such as La Crosse, Eau Claire, and Platteville, confidence is higher that any precipitation falls entirely as snow, with limited melting during the daytime.
Major transportation corridors including I-90, I-94, U.S. 12, and U.S. 14 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 active snowfall, as untreated surfaces remain frozen for extended periods. 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 stocked 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.
