The National Weather Service has issued winter storm warnings and winter weather advisories for parts of southeast Wisconsin, including Washington, Ozaukee, Dodge, Fond du Lac, Sheboygan, Jefferson, Rock, Walworth, Racine, Kenosha, and Milwaukee counties. The storm system is expected to bring a mix of precipitation types, including snow, sleet, freezing rain, and thunderstorms, leading to hazardous travel conditions with icy roads, heavy snow, strong winds, and low visibility.

Why it matters

This winter storm has the potential to cause significant disruptions across the region, with the possibility of power outages, school and business closures, and dangerous travel conditions. The combination of ice, snow, and high winds could lead to downed trees and power lines, making it crucial for residents to monitor the weather and heed any safety warnings.

The details

The winter weather advisories and warnings are in effect from Sunday evening through Monday afternoon. Areas near Lake Michigan are forecast to see lower snow totals of 2-5 inches, but still hazardous travel due to light icing and strong winds. Inland areas are expected to see higher snow accumulations of 4-8 inches, with the potential for locally higher amounts. The icing potential is also higher in northern locations, which could lead to more dangerous travel conditions and power outages. South of I-94, the focus will be on the risk of a flash freeze as wet surfaces transition to freezing rain and sleet overnight, creating black ice.

  • Winter weather advisories are in effect for Washington County until 7 p.m. Sunday and Ozaukee County until 4 p.m. Monday.
  • A winter storm watch is in effect for Dodge, Fond du Lac, and Sheboygan counties through 4 p.m. Monday.
  • A winter storm warning has been issued for Jefferson and Rock counties starting at 7 p.m. Sunday through 4 p.m. Monday.
  • A winter weather advisory has been added for Walworth, Racine, Kenosha, Waukesha, and Milwaukee counties from 10 p.m. Sunday to 4 p.m. Monday.

What they’re saying

“While temperatures remain above freezing during the day on Sunday, rain and storms will favor most of southeast Wisconsin. The bad news about this, any areas that are wet won't have much time to be treated prior to precipitation transitioning over into freezing rain and sleet again tonight. This will cause a flash freeze on most surfaces, creating black ice.”

“Winds strengthen out of the northwest around the back side of the low pressure, bringing in cold air which will change precipitation over to snow from late Sunday night into Monday morning. Unfortunately, heavy snow and strong winds blowing snow on Monday can cause whiteout conditions, which is not good for the morning commute hours. It is advised to stay off of roads if possible until visibility improves tomorrow and crews can get out to clear the roads.”
