Overview

An unusually warm and humid airmass for mid-April was in place across the local area, well ahead of a cold front that stretched from the central Plains into the northern Great Lakes. Thunderstorms the prior night across the mid-Mississippi Valley evolved into a mesoscale convective vortex, which is essentially a small area of low pressure caused by complexes of thunderstorms. Mesoscale convective vortices, or MCVs, are known to locally enhanced wind shear and add lift to the atmosphere that can encourage renewed thunderstorm development. This feature moved east across northern Ohio during the afternoon and early evening hours on April 15th, interacting with the unseasonable warmth and humidity to cause a round of scattered severe thunderstorms across the area. Many thunderstorms were supercells (i.e. rotating) and produced large hail, up to nearly tennis ball-sized in the southeastern Cleveland suburbs. Some thunderstorms also produced damaging winds, with a microburst producing 90 MPH winds in southeastern Trumbull County.
