Hazy conditions expected again today then a line of showers and thunderstorms are expected to move in late tonight from the north and push southward through the day tomorrow. Main threat will be damaging winds through the event but can't rule out all threats tomorrow afternoon.
Here is one of the computer models that the NWS uses, called the "HRRR" output for future radar prediction for tonight's storms and heavy rain threat. Activity will initially form north of Chicago later this evening before moving down into central Indiana mainly after 1 AM, reaching the I-70 corridor around 5 AM. In addition to isolated strong to severe winds gusts, locally heavy rain fall is also possible.
