The National Weather Service has issued a severe weather warning for southeast Wisconsin, with thunderstorms expected to arrive in western counties like Jefferson, Dodge, and Walworth near or after 5 p.m. on Friday. The storms could bring a range of severe weather, including hail, damaging winds, and even the potential for tornadoes, especially in central and western parts of the state before the system moves eastward.

Why it matters

Severe storms can cause significant property damage, power outages, and pose a threat to public safety. This system follows a month of heavy rainfall that has already broken records in the Milwaukee area, raising concerns about additional flooding.

The details

According to forecasts, the storms are expected to develop along a cold front moving across the upper Midwest. The storms will likely start in the western counties and then move eastward, with the potential for isolated tornadoes, large hail, and damaging straight-line winds. Heavy rainfall could also lead to further flooding concerns in an area that has already seen over 8 inches of rain this month, breaking a local record.

  • Thunderstorms are expected to begin arriving in western counties near or after 5 p.m. on Friday, April 17, 2026.
  • The severe weather threat is expected to continue into the late evening hours, potentially lasting until around midnight.
