    Similar to the threat of significant severe weather trending south, the potential for flash flooding is also focusing south of I-80. Farther north the flash flooding threat may end up more localized compared to earlier concerns but still worth monitoring. #ILwx #INwx
    Headline: Update on Flash Flooding Threat Today.  Sub Headline: Greatest flash flooding threat also focusing south of I-80.  What To Expect.  Areas near and north of I-80: Periods of Heavy Rainfall through this evening.  May cause ponding on roads and parking lots.  Localized flash flooding possible. Areas well south of I-80: Multiple Rounds of Torrential Rainfall through early evening.  May flood roads, low-lying areas, fields, and basements, and cause rapid stream/creek rises.  What To Do.  Prepare now for potential flooding if you live in a flood prone area, especially south of I-80. Know alternate routes for traveling. Graphic Created: Wednesday, June 17, 2026 2:36 PM CDT.
