Snow has diminished over central Wisconsin and will gradually
diminish through 10 pm over eastern Wisconsin, including the Fox
Valley. Expect additional fluffy snowfall less than 1 inch, mainly
for southern portions of the Fox Valley, including Oshkosh, to the
lakeshore. The snow has made roads slippery this evening, so if

roads, sidewalks, and other surfaces. Use caution if traveling this
evening by increasing your following distance and allowing extra time
to reach your destination.
Expect the snow and freezing drizzle to gradually diminish after 7
pm over central Wisconsin.
