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

Peak winds were estimated near 100 mph. This tornado passed across Highway 51 about a mile south of Broseley. A farm machine shed was leveled. Numerous other sheds or small structures were damaged or destroyed. Large irrigation piping was blown hundreds of feet in varying directions. Farm implements were blown over, and two camper units were rolled over. At least four houses received minor to moderate damage to roofs, siding, and windows. Numerous trees were uprooted. There was also some spotty straight-line wind damage to outbuildings and trees just north and east of the tornado track. This tornado was the first of several that were spawned by the same eastward moving supercell.

The wider storm

A cluster of severe thunderstorms over south central Missouri organized into a bowing line of storms as it tracked eastward during the evening. An embedded supercell within the line spawned several tornadoes along an east-west corridor from Ripley County eastward to New Madrid County. A couple of significant tornadoes and damaging wind events accompanied this line, along with large hail. The storms developed along and just ahead of a cold front as it pressed southward into the Lower Ohio Valley and extreme southeast Missouri.

Began near Broseley (36.6611, -90.2736).
