Wider weather episode

A surface Low over Missouri early in the afternoon of March 2nd strengthened to below 990mb as it moved north into Michigan by the evening hours. Around dawn, a warm front moved north of the Ohio River. Scattered strong storms developed along this front across northern Kentucky, bringing several reports of dime sized hail. By mid afternoon, the combination of strong wind shear, temperatures rising to the upper 70s and over 2000 Joules/kg of CAPE led to the development of numerous supercells. Several of these storms produced tornadoes not only in north central Kentucky, but later in the evening across eastern Kentucky. Large hail was common, with several reports of baseball sized hail that damaged automobiles and roofs.
