Madison, Wisconsin – Drivers across south-central Wisconsin could see visibility suddenly drop to around 1 mile or less through late Sunday morning as narrow bands of snow showers sweep across the region, though roads are expected to remain mainly wet with no accumulation.
According to the National Weather Service in Milwaukee/Sullivan, these scattered snow showers will track east through late morning, with the most concentrated band stretching from Iowa County through Dane and into Rock County. Visibility may briefly dip below 1 mile in heavier bursts, especially along U.S. 18/151 near Dodgeville and I-39/90/94 corridors around Madison.
In Dane County, Madison commuters may notice quick changes in visibility between 9 a.m. and noon, particularly on open stretches and elevated roadways. Rock County, including Janesville, could see similar brief reductions, though pavement temperatures should prevent any snow from sticking. Farther south in Green County, Monroe remains near the southern edge of the band, where light snow may mix with rain at times.
Elsewhere, including Columbia County and Portage, only spotty flurries or sprinkles are expected as drier air limits how much reaches the ground.
Drivers should use headlights during reduced visibility and allow extra following distance, even if roads appear clear. Sudden bursts of snow can catch motorists off guard, especially on rural highways.
Conditions are expected to improve by early afternoon Sunday as the snow showers exit east, with no winter advisories currently in effect.
