Southern Wisconsin Weather Alert: First Snowfall of the Season Expected Saturday Evening

Milwaukee, WI – Southern Wisconsin is preparing for its first measurable snowfall of the season this weekend, as a cold front brings a mix of rain and snow across the region on Saturday afternoon and evening, according to the National Weather Service in Milwaukee/Sullivan.

Forecast Overview

Forecasters say rain will begin Saturday afternoon, gradually changing to all snow shortly after sunset as temperatures fall below freezing. Light accumulations are expected, mainly on grassy and elevated surfaces, with totals ranging from a dusting to around one inch in some areas.

The greatest potential for measurable snow will occur across south-central to southeastern Wisconsin, including communities north of Madison and through the Kettle Moraine region.

Regional Impacts

Lakeshore areas such as Milwaukee and Racine will likely see mostly rain with limited accumulation, while inland areas could experience brief but steady bursts of snow as colder air deepens overnight.

By late Saturday night, snow is expected to taper off from west to east, leaving behind patchy slick spots where temperatures drop into the upper 20s.

“Widespread travel issues aren’t expected, but untreated and elevated roads may become slippery as temperatures fall,” forecasters advised.

Travel and Safety Guidance

Drivers are urged to exercise caution during the evening commute, especially in rural and open areas where temperatures will drop fastest. Any leftover moisture on roadways could freeze by early Sunday morning, leading to isolated icy conditions on bridges, overpasses, and ramps.

Residents should also prepare for rapidly changing conditions — rain, snow, and freezing temperatures could occur within just a few hours as the system passes.

Outlook

This early-season snowfall signals the beginning of Wisconsin’s winter transition, with below-average temperatures expected to persist through the week ahead. Meteorologists say additional snow chances could return later next week as the cold air mass settles in.
