   Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

6. EF5over 200 mph

   Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

7. Unrated

   The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

14 damage points were recorded along this path by NWS PAH, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 85 mph.

• Lots of gutter and soffit damage. Projectile holes from tree branches. Tin from nearby barn lifted 40ft into the tree.
• About a 7 ft piece of 2x4 impaled into the ground several inches in a field, across the street from demolished machine shed.
• 30 x 50 machine shed destroyed with boards wrapping around the house causing damage. Evidence of a projectile in the field across the street as well.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

A few supercell thunderstorms formed over southeast Missouri during the warmth of the afternoon. The storms gradually intensified immediately ahead of a cold front across southeast Missouri, where lower 60's dewpoints were in place. Pockets of diurnal heating resulted in moderate instability, with mixed layer cape values from 1500 to 2000. A moderately strong low level southerly wind flow was adequate for a brief tornado or two. With deep-layer winds oriented perpendicular to the initiating cold front boundary, conditions were favorable for supercells capable of locally damaging winds, isolated large hail, and a brief tornado.

A weak tornado briefly touched down on County Road 806 within a larger area of straight-line winds. The evidence of the weak tornado was based on the orientation of the damage. This included uprooted trees oriented to the southeast, along with lofted tin from a nearby damaged machine shed and a large two-by-four impaled into the ground. The tornado also destroyed a 30-by-50 foot machine shed near some other tree damage in the vicinity. The home next to this machine shed sustained damage to its soffit and gutters. The siding was damaged by debris. Power lines were down. A trained spotter reported seeing a funnel cloud. Peak winds were estimated near 85 mph.

4 minutes of warning. NWS PAH issued a tornado warning for this county at 21:58 UTC, 4 minutes before the tornado touched down, in force until 22:30 UTC.

The county was under a tornado watch, issued at 19:05 UTC and running to 03:00 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 20:10 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
