Wet Snow Could Snarl Tuesday Morning Commute Across Wisconsin

WISCONSIN — A narrow band of rain and snow is expected to move across Wisconsin overnight, with parts of central Wisconsin likely seeing slushy accumulations and slick travel conditions during the Tuesday morning commute, according to the National Weather Service.

Forecasters say the system will track west-to-east late tonight, with rain holding on across southern and lakeshore counties but changing to all snow farther north. Areas along and north of a line from the Wisconsin Dells to Montello and Berlin have the best chance at seeing 1 to 2 inches, with isolated totals near 3 inches.

Most of that snow is expected to fall between 3 AM and 9 AM Tuesday, when snowfall rates could exceed a half-inch per hour.

Where Travel Impacts Are Most Likely

The NWS highlights a corridor of higher-impact travel risk across central Wisconsin, where colder road temperatures and short bursts of moderate snow could lead to slushy, slick spots.
The zone could shift slightly north or south by about half a county as the system unfolds.

Counties with the greatest chance for accumulating snow include:

• Adams
• Columbia
• Marquette
• Green Lake
• Sauk
• Dodge (north)
• Fond du Lac (north/west)

Areas south of I-94 and closer to Lake Michigan are forecast to remain mostly rain or a rain/snow mix, with little to no accumulation.

• Early Tuesday (3–9 AM): Main window for accumulating snow in central Wisconsin.
