Flash Flood — Montgomery, Illinois

2022-09-04 · near Butler, Montgomery, Illinois

Event narrative

Up to five inches of rain fell in a short amount of time, especially in the Lake Glenn Shoals and Irving areas. Several roads were flooded including Illinois Route 16 just northeast of Irving. A vehicle was driven into the flood waters and stalled in this area. The driver was rescued and no injuries were reported.

Wider weather episode

An upper level system stalled out over the region with plenty of low level moisture convergence on the nose of a modest low level jet. The forcing was focused over south central Illinois, so this is the area that got the most rainfall. A couple of isolated areas had over 4 inches of rain in a short amount of time, causing flash flooding.
