Hardest punch of days-long snowstorm still to come for southern Wisconsin. See how much will fall and when

{{featured_button_text}}

The worst of a days-long snowstorm still is to come for southern Wisconsin, with the most snow expected south and east of Madison, and less to the north and west, according to forecasters.

A winter weather advisory is in effect from 9 p.m. Friday to 6 a.m. Saturday for the counties of Jefferson, Rock, Waukesha, Walworth, Racine and Kenosha, where up to 3 to 5 inches still could fall after a break Friday afternoon, the National Weather Service said.

Madison is predicted to see 2 to 4 inches Friday night and Saturday, with the storm expected to hit hardest across southern Wisconsin later Friday night into early Saturday.

Officially, the storm dropped 0.2 inches on Wednesday and 1.3 inches on Thursday at the Dane County Regional Airport, with no totals yet available for Friday, when moderate snow fell before daybreak across the area, the Weather Service said.

Periods of light to occasionally moderate snow are expected to continue Friday morning, with some rain at times especially over southeast Wisconsin. After a break, moderate to at times heavy snow is expected Friday night through Saturday morning before the snow, possibly with some rain mixed in, tapers off during the afternoon.

In total Friday, overnight and Saturday if maximum possible totals fall, Madison could see 4 ½ inches, La Crosse 2 inches, Eau Claire 1 ½ inches, Green Bay 3 inches, and Racine 3 inches.

The system is getting a boost from a disturbance in the upper atmosphere that also will bring the threat for heavy rain and thunderstorms farther south, AccuWeather said.

A focal point for some of the steadiest and heaviest snowfall is likely from northern Missouri to southeastern Iowa, northwestern and northeastern Illinois and southeastern Wisconsin, with 3 to 6 inches expected and up to 8 inches possible in some locations.

The city of Madison Streets Division said it continues to plow and salt the main thoroughfares as needed, and apply sand in residential areas.

In Madison on Friday, look for rain and snow before 2 p.m., then snow likely from 2 p.m. to 3 p.m., then a chance for rain and snow after 3 p.m., with a high near 34 and northeast winds around 10 miles per hour, and possible accumulation of less than a half-inch, the Weather Service said.

Overnight, there’s a chance for rain and snow before 7 p.m., then snow, with possible accumulation of 1 to 3 inches as the low edges down to around 32.

Skies over Madison should be mostly cloudy Sunday and Monday, cloudy Tuesday and Wednesday, and mostly cloudy Thursday, with highs near 35, 35, 35, 37 and 36, and lows Saturday night through Wednesday night 31, 26, 27, 27 and 26.
