Highs will soar back into the mid 70s due to a strong southerly wind that gusts up to 45 mph at times. Hence, wind advisories will be in place from 8 a.m. Wednesday to 1 a.m. Thursday. Thursday: Rain turns more scattered for areas along and south of interstate 70. A front will begin to stall out south of Indianapolis, setting the stage for multiple waves of rain into the weekend.

The next areas of concern for heavy rain will be Friday night into Saturday morning and late Saturday.
