A multi-faceted storm system that began dropping snow on Wisconsin Wednesday night is far from over, with several more inches to fall by the time the storm exits Saturday, according to forecasters.
As of 6 a.m. Thursday, 1.2 inches of snow had fallen in Madison, 0.9 inches in Racine, and more to the north and west, the National Weather Service said.
Light snow will continue Thursday morning, additional periods of light snow are expected Thursday afternoon and overnight, and periods of light to occasionally moderate snow are expected Friday through Saturday, the Weather Service said.
The Weather Service’s predicted snow totals for the rest of the storm have increased from Wednesday for Madison with less than an inch today, 1 to 2 inches overnight, and 3 to 5 inches Friday into Saturday.
Elsewhere across the state, maximum possible additional totals through Saturday include 2 ½ inches for La Crosse, 1 ½ inches for Eau Claire, 6 inches for Green Bay, and 3 ½ inches for Racine.
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, AccuWeather said.
The entire Midwest and western Great Lakes region will finally say goodbye to the system by Sunday, with slightly above-average temperatures expected in its wake.
