- Heat indices will top out around 100 degrees Wednesday afternoon south of I-72 due to high temperatures in the 90s and rising humidity levels.
- Scattered thunderstorms are forecast Wednesday afternoon, becoming more widespread Wednesday night along a stalled front; localized heavy rainfall of 1 to 3 inches could cause localized flooding, particularly south of I-70. There is a marginal risk (level 1 of 5) for severe thunderstorms for much of central and southeast Illinois.
