1,899 first-hand accounts of flood events in Ohio, ranked by impact. Each is a NOAA-written narrative of the moment.
A large area of high pressure centered over the southeast CONUS allowed for a warm, tropical airmass to advect northward into northern OH. Surface dewpoints in the low 70s and PWAT's near 2 provided a thermodynamically favorable environment for heavy rainfall.
