What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 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.

What the National Weather Service wrote

A brief EF3 tornado developed along the apex of a bow echo, and touched down northwest of Liberty at 12:56 am CST. The tornado tracked east-northeast for nearly one mile before dissipating at 1:00 am. Four homes were destroyed and 117 suffered damage.

The wider storm

An early morning line of storms developed across south central Kansas. This line of storms, developed into a Bow Echo, which raced northeast at speeds in excess of 50 mph, into the greater Kansas City metropolitan area and surrounding communities, early on the morning of May 2, 2008. The Bow Echo generated hurricane force winds, which brought widespread wind damage, to areas from Olathe Kansas, northeast through Kansas City, to Brookfield in north central Missouri. As the Bow Echo moved through Kansas City, it spun up a couple of tornadoes along the apex, or nose, of its leading edge. One EF3 tornado moved across the north side of Gladstone, while the other EF2 tornado moved through an area just northwest of Liberty. However, most of the damage was due to the strong straight line winds, that were also occurring along the apex of the Bow Echo. Gladstone reported 20 homes destroyed, 280 homes with damage, and 19 businesses damaged. North Kansas City had 4 homes destroyed, and 117 damaged. Independence had 13 homes and two businesses badly damaged. Six people were injured and damage was in the millions of dollars.

Began near Liberty Mitchell Arp (39.2929, -94.4903).
