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 moved from west to east across southern Stoddard County, passing across the town of Bernie. Peak winds were estimated near 95 mph. Numerous farm machine sheds of varying sizes were leveled. Several homes in Bernie received minor to moderate damage, ranging from loss of shingles to blown out windows and wall sections. A small camper unit was overturned. Several grain bins were damaged on the west side of Bernie. Numerous trees were uprooted or snapped. Very strong straight-line winds up to 95 mph just south of the tornado track produced equally intense damage, including a couple leveled barns. This tornado was one 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 Powe (36.6614, -90.0897).
