Wind over Lake Michigan makes for dangerous swim conditions and storms return by Monday.
3 Things To Know:
- Moderate Swim Risk for Sheboygan and Ozaukee counties Friday afternoon and evening.
- Warm and humid conditions will pave the way for thunderstorms over the weekend.
- Possible severe storms Sunday through Monday affecting southern Wisconsin.
Swim Risk Advisory
On Friday afternoon and evening, a Moderate Swim Risk is expected for Sheboygan and Ozaukee counties. Waves between 2 to 4 feet will create hazardous conditions in the water. It’s best to avoid piers, breakwalls, and river outlets during this time.
Weekend Forecast
Temperatures will rise into the mid to upper 80s on Saturday, accompanied by increasing humidity with dewpoints approaching 70°F. While there is potential for showers Saturday afternoon due to a weak surface trough, current confidence in precipitation is low, keeping the forecast mostly dry for now.
Potential Of Storms
Looking ahead to Sunday, we can expect thunderstorms to develop, particularly as a stalled frontal boundary will influence the region. The exact location remains uncertain, but models indicate a substantial severe risk. “SPC introduced a 15% risk for severe storms Sunday and Monday for southern WI.”
Storm initiation may vary, with some models suggesting storms could form in central Wisconsin, moving southeast. Should conditions align, additional severe potential could arise with significant winds and other dangers. A secondary storm risk may follow into Monday as another shortwave moves across the area.
Stay Informed
As we transition into next week, the weather will remain warm and humid, with varying chances for thunderstorms. Keep an eye on the changing conditions as the week progresses.
