Thunderstorms are expected to develop this afternoon, and possibly become severe. While severe thunderstorms are possible across the entire area during the late afternoon and evening, the best chance for severe storms will be across east central Missouri into southwest and south central Illinois. Damaging winds will be the primary threat, but large hail and a few brief tornadoes will also be possible.
Showers and a few thunderstorms are expected Thursday (60 to 80% chance), and a few are likely to linger into Friday as well. However, dry conditions are expected to return over the weekend.
A brief EF-1 tornado touched down west of Bates Creek Camp on April 29th and caused damage to some buildings and trees before moving northeast into southern Potosi. The tornado lifted near the Washington County Memorial Hospital.
