Milwaukee, Wisconsin – A developing winter storm could bring more than 8 inches of snow to parts of Wisconsin between Saturday night and Sunday night, creating the potential for widespread travel disruptions across central and northern parts of the state.

According to the National Weather Service in Milwaukee/Sullivan, accumulating snow is expected to spread across most of Wisconsin during the weekend, though the exact location of the heaviest snow band remains uncertain. Forecasters say the axis of the heaviest snowfall could exceed 8 inches, depending on how the low-pressure system tracks across the Midwest.

Current projections show the greatest snow potential stretching across central and northern Wisconsin, including areas near Wausau, Rhinelander, and Rice Lake, where prolonged snowfall could significantly impact travel. Farther south, including Madison, Janesville, and areas near the Illinois border, warmer air may lead to more rain than snow, reducing totals but still creating wet and potentially hazardous roads.

Major travel corridors including Interstate 39, Interstate 41, and Interstate 94 could see rapidly deteriorating conditions if heavier snow bands set up over central Wisconsin during the weekend.

State transportation officials warn that significant travel impacts are possible during the heaviest snow Sunday, especially where snowfall rates increase and visibility drops.

Residents are encouraged to monitor updated forecasts, prepare for possible changes to travel plans, and check road conditions before heading out as the storm track becomes clearer. Additional winter weather watches or warnings may be issued as the weekend system approaches.
