12 damage points were recorded along this path by NWS EAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 80 mph.

• Clear path through two tree lines. 30 yards wide
• top of north facing garage door is bent in.
• Several large limbs and small trees down along Tontine Road. Most of the trees had been moved, suggesting several had blocked the road as they were initially damaged.
• Multiple trees down in this grove. Some appear to have been snapped.

In the late evening hours of May 6th and early morning hours of May 7th, several severe linear features moved through Missouri from west to east. These produced widespread 60 mph straight line wind damage with numerous embedded QLCS mesovortices and a few confirmed QLCS tornadoes.

NWS storm survey confirmed a 6 mile long EF-0 tornado that began near the community of Hoover in northeastern Platte County, moving to the northeast and ending on the Platte/Clay County line about two thirds of a mile south of the intersection of County Line Road and Ridgely Road. Peak wind gusts of 80 mph were estimated based upon damage indicators. Most damage was tree damage.

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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 00:50 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Pleasant Hill radar (KEAX), 74 km away, was scanning. The volume nearest the touchdown began at 03:59 UTC.

40 more were confirmed in the United States that day.

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.
