Main threats are strong and erratic winds, large hail, and heavy rain. Look for the chance of showers and wet thunderstorms to continue on Wednesday. Temperatures today and Wednesday will remain slightly below normal with seasonably high humidities. By Thursday into the weekend, warmer and drier conditions look to return, but cannot rule out isolated showers and thunderstorms each day. Arends/Palmquist.
