1,899 first-hand accounts of flood events in Ohio, ranked by impact. Each is a NOAA-written narrative of the moment.
A broad ridge of high pressure was present over the eastern CONUS, with a warm, humid airmass in place over northern OH. PWAT values were near 1.9 and MLCAPE values ranged from 1000-2000 j/kg. Steering flow was minimal, which allowed for slow moving thunderstorms.

Read the full account →An intense low pressure system developed over the Southern Plains, in conjunction with an upper-level trough. This low pressure system developed much like a winter weather system, as the storm deepened as it progressed eastward.
Read the full account →A warm, moist airmass remained in place through the latter half of the month which allowed for daily shower and thunderstorm chances. Training storms was the primary factor to the resultant flash flooding as cells developed upshear of the initial updrafts in West Virginia, Ohio,…
