What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

The wider storm

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.

Began near Chambers (37.8345, -86.7814).
