A surface warm front resided over central Ohio around daybreak on March 28th. This front drifted northward to near Lake Erie by the end of the day as the parent low moved from western Kansas to north-central Iowa. A southerly return flow of warm, humid, and weakly to moderately unstable air from the Gulf of Mexico underwent isentropic lift along the warm front, generating numerous showers and thunderstorms over northern Ohio during the late morning through early afternoon. Strong vertical wind shear allowed some of the thunderstorms to become supercells. These thunderstorms were elevated north of the surface warm front, where the boundary layer remained cool and stable amidst a northerly low-level flow off Lake Erie. Steep mid-level lapse rates and large amounts of most-unstable CAPE in the hail growth zone allowed multiple storms to produce severe hail, while the cool boundary layer allowed hail to easily survive its fall to the surface. Several reports of large hail as big as hen eggs to tennis balls were received.
