Update: 3/25/23 @ 12:30 a.m.: A correction has been made to reflect that NWS on Friday afternoon issued a Winter Weather WARNING (more significant than the advisory originally stated in our headline). At this time the warning has been extended to Jefferson and Rock Counties. Additionally, the probability for over 8″ of snow in Whitewater was reduced from 38% to 26%.

According to the National Weather Service Milwaukee/Sullivan Office (NWS) at 3:30 p.m. on Friday, Walworth County is under a Winter Weather Warning effective from 4 a.m. to 1 p.m. on Saturday due to the anticipated heavy, wet snow from early Saturday morning into Saturday afternoon. The warning is also in effect for Waukesha, Milwaukee, Racine and Kenosha counties. NWS states that “the combination of the heavy, wet snow and stronger north to northwest winds will cause concerns for tree damage and power outages, especially across southeast Wisconsin. (NWS considers Whitewater to be in South Central Wisconsin.) The weather service acknowledges that, “There remains some uncertainty with the location of the higher-end snowfall amounts, as they may still shift a little to the north or south.”

Caution is advised for travel during the peak snowfall rates, mainly between 6 a.m. and 11 a.m. on Saturday, especially on secondary and untreated surfaces.

NWS estimates a 54% probability that the Whitewater area will receive 6-8″ of snow, and a 26% probability of over 8″ of snow.
