This relatively weak, short-lived tornado was spawned by the same supercell thunderstorm that produced longer and more destructive tornadoes over Livingston County and eastern Crittenden and Webster Counties. Many trees were down, and a couple of trailers were destroyed or heavily damaged.

This short-lived tornado crossed U.S. Highway 60 northeast of Marion, downing numerous trees. This tornado was one in a series of tornadoes spawned by a supercell thunderstorm that tracked eastward across Livingston, Crittenden, and Webster Counties.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

21 minutes of warning. NWS PAH issued a tornado warning for this county at 07:14 UTC, 21 minutes before the tornado touched down, in force until 08:00 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 General Thunderstorms Risk. The outlook in force was issued at 05:23 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 Paducah radar (KPAH), 61 km away, was scanning. The volume nearest the touchdown began at 07:34 UTC.

37 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.
