6 Inches Of Snow Possible For Parts Of SE Wisconsin: Weather Forecast

MILWAUKEE, WI — The National Weather Service still says southeastern Wisconsin could see its first light snow of the season Saturday night, with minor accumulations expected as colder air moves in behind a passing low-pressure system.

Rain will arrive late Saturday morning or early afternoon, spreading from west to east. As temperatures drop below freezing after sunset, precipitation will transition to snow, with slushy accumulations of less than 1 inch possible on grassy or elevated surfaces. Roads could become slick in spots overnight, forecasters said.

The changeover to all snow is likely after 10 p.m., with flakes tapering off by early Sunday. A few lingering light snow showers (20–30 percent chance) may continue into Sunday morning, though additional accumulation isn’t expected.

Highs Sunday will only reach the mid-30s, with gusty northwest winds up to 30 mph making it feel even colder.

The NWS said this will be the coldest air mass of the season so far, lasting into early next week.

Another round of light snow or flurries is possible Sunday night into Monday, but any new accumulation should remain minimal. Temperatures will rebound slightly by midweek, with highs returning to the 40s.
