EF2 tornado in Perry County, Missouri

This long-track tornado crossed into southwest Perry County from Madison County. Along the Madison/Perry county line, the width was about half of a mile wide, with numerous trees snapped and uprooted. The tornado then moved nearly parallel to County Road 738. Here several houses and a hunting lodge sustained minor damage, mainly to roofs and posts of a porch. One barn and a small shed were destroyed, along with numerous uprooted and snapped trees. The tornado continued on to produce tree damage on Highway 730, where it was only a few hundred yards wide and dissipated shortly thereafter. Peak winds in the Perry County portion of the path were near 112 mph, putting it barely into the EF-2 category. However, the tornado peaked at EF-3 intensity earlier in its life cycle.

The severe weather episode began as a series of supercells and transitioned to a squall line. A supercell thunderstorm produced a strong long-track tornado across southeast Missouri that ended in southwest Perry County. A short EF-1 tornado associated with a squall line struck southern Perry County shortly thereafter. A longer track EF-1 tornado also impacted eastern Wayne County into southern Bollinger County. The storms preceded a strong cold front that trailed south-southwest from a low pressure center over west central Illinois. Dew points ahead of the front were in the lower to mid 60's. Instability was strong enough to support severe storms, given that wind shear was quite strong. Mixed-layer capes were around 1000 j/kg.
