La Crosse, Wisconsin – A fast-moving winter system is expected to sweep across western Wisconsin Sunday afternoon and evening, bringing a brief but potentially hazardous mix of snow, sleet, and freezing rain that could quickly make roads slick.
According to the National Weather Service in La Crosse, the system will move west to east between midday and early evening, with most locations seeing only a one- to three-hour window of impacts. Accumulating snow is favored along and north of Interstate 94, where the probability of at least 1 inch of snow rises into the moderate to high range. Areas south toward Interstate 90 are more likely to see a wintry mix, increasing the risk for a light glaze of ice.
Travel impacts could be highest during the late afternoon and early evening hours, especially on bridges, overpasses, and untreated secondary roads. The probability of a glaze of ice increases between I-90 and I-94, including areas near Rochester, Winona, Black River Falls, and Tomah, where even minor icing could create hazardous driving conditions.
Because the system is expected to move quickly, snowfall and icing amounts should remain limited, but the short duration may still catch drivers off guard. Motorists are urged to monitor updated statements, adjust travel plans if possible, and slow down if encountering slick conditions.
Conditions should improve later Sunday evening as the system exits, though lingering slick spots may persist overnight. Additional advisories could be issued as timing and precipitation types are refined.
