The northern Indiana National Weather Service office published the infographic above along with the information below:
Hot and muggy conditions will remain this evening ahead of an approaching cold front. This front is expected to spark the development of showers and thunderstorms that will move into the area later this evening, most likely after 8 pm EDT. There remains a slight risk for a few of these storms to be strong to severe with damaging winds and heavy rainfall as the main threat. This threat will be highly conditional depending on whether or not the storms can organize before instability is lost as the sun sets. Cooler, less humid air will move in behind the front with highs in the 80s for the weekend. For the latest advisory and forecast information see our website at www.weather.gov/iwx.
