The hottest day of the week will be Wednesday as temperatures climb into the low and mid 90s. These hot temperatures combined with high humidity will result in some peak heat indices in the triple digits, especially along and west of I-65.
Widespread showers and storms ahead of a slow moving cold front will be around late Wednesday night into Friday. The best chance for rainfall amounts over 1" will be along and north of I-64. A few strong storms with gusty winds will also be possible later Wednesday night.
