The National Weather Service Office in Green Bay has issued a winter weather advisory for 5 to 7 inches of snow from 6 p.m. Friday through 6 p.m. Saturday (Jan. 17-18).
In addition, a lakeshore flood advisory will be in effect from 6 p.m. Friday to 6 a.m. Saturday.
“A strengthening area of low pressure is forecast to move from the central Plains into the Great Lakes Friday night into Saturday,” the advisory said. “Snow is expected to reach central Wisconsin late Friday afternoon, become locally heavy at times Friday night and gradually diminish Saturday afternoon. A little freezing rain or sleet may also mix in at times Friday night over parts of central and east-central Wisconsin. Total snow amounts of 5 to 7 inches are expected with locally higher amounts possible. Increasing west winds on Saturday could also produce blowing and drifting of the snow.”
Meanwhile, strong southeast winds may cause water to back up on rivers that flow into the lake, leading to lakeshore flooding. High waves on Lake Michigan may cause shoreline erosion and localized flooding.
Wind chills are expected to fall into the 10- to 20-below-zero range across central Wisconsin Saturday night and Sunday night.
