The episode as NWS PAH wrote it up.
Around 6 inches of rain in 24 hours caused extensive flooding of streams and roads. A state of emergency was declared by the Illinois governor, which was later upgraded to a federal disaster area. Two county roads were closed in Massac County. One was closed by a bridge washout, and water rushing across the other road created a 15-foot wide gap. So many roads were damaged that the county highway department ran out of barricades.
The Paducah radar (KPAH), 18 km away, was scanning. The volume nearest the first event began at 23:30 UTC.
1 flash flood. Local standard time, as filed.
