3 Things To Know:
- Thunderstorms this afternoon may produce winds of 30 to 50 mph, with isolated gusts up to 60 mph.
- A Flood Watch is in effect until 10 PM, with localized flooding likely, especially in urban areas.
- Hazardous boating conditions are expected on Lake Michigan tonight into early Friday morning.
Weather Now:
Northeast Wisconsin is in for a challenging weather afternoon as a potent low-pressure system moves northeast from Iowa. Thunderstorms are expected to develop between 3 PM and 8 PM, bringing potential hazards like strong winds and heavy rainfall.
Thunderstorm Timing and Impacts
Thunderstorms could produce wind gusts of 30 to 50 mph, with the possibility of isolated gusts reaching as high as 60 mph. Although the primary risk for severe weather appears to be heading south of our area, gusty winds can still occur with any storm that forms.
Significant rainfall is another major concern this afternoon. Many areas in central Wisconsin remain saturated from previous rainfall, and a Flood Watch is in effect until 10 PM. Expect rapid rainfall rates that could lead to urban and localized flooding, especially in areas with poor drainage.
As the National Weather Service notes, “Flash flood guidance is notably low across areas that received 2 to 4 inches of rain yesterday…” This underscores the potential for quick flooding in susceptible areas.
Boating Conditions and Upcoming Weather
Boaters should also be cautious, as hazardous conditions with high waves and dangerous currents are expected on Lake Michigan beaches from tonight into early Friday morning.
Looking ahead, conditions will clear overnight, but the chance for additional thunderstorms returns Friday night into Saturday as another cold front moves through.
Extended Forecast
Following the weekend, temperatures are expected to drop, settling into the mid-60s to mid-70s by the following week. Continued chances for precipitation are possible starting on Tuesday.
