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.

What the National Weather Service wrote

This tornado touched down in the heavily forested county of Wayne, just a few miles north of the community of Shook. Numerous trees were uprooted and snapped. The tornado passed mainly through wooded country during the Wayne County portion of its path. The tornado then crossed into Bollinger County.

The wider storm

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.

Began near Shook (37.0968, -90.3200).
