The wider storm

During the evening of July 20th, an MCS rode into south-central Illinois. Though the system as a whole kept pushing southeast during the evening, back-building and additional development along its northwestern edge caused it to rain constantly over Fayette County for hours. Between about 7:45 pm CDT and midnight, central Fayette County received 8.7 inches of rain of a total 13.5 inches. This resulted in flash flooding in the form of impassable roadways and stranded vehicles. A Flash Flood Emergency was issued for central Fayette County during this event.

Began near Reno (38.9599, -89.5088).
