The storms are expected to lose some steam before reaching central Indiana early Thursday as they move away from upper jet stream air support.  A cold front will be slowly sagging south into the state late Thursday and will likely aid in new scattered showers and storm development Thursday afternoon.

The added cloud cover will prevent temperature from reach 90 degrees Thursday but the humidity will still be felt.  The high levels of humidity will help feed locally heavy downpours under some of the storms Thursday afternoon and evening.
