A supercell thunderstorm tracked out of Ottawa County, Oklahoma and into Newton County, Missouri. The storm spawned a tornado approximately 8 miles SW of Neosho and damaged around 40 structures across rural sections of the county. The tornado also struck a turkey farm killing around 200 turkeys prior to lifting approximately one mile west of Neosho.

From the same supercell thunderstorm that produced the F-1 tornado across rural southwest Newton County, a weak tornado briefly touched down in a neighborhood on the western edge of Neosho. One house sustained significant roof damage.

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

24 minutes of warning. NWS SGF issued a tornado warning for this county at 03:01 UTC, 24 minutes before the tornado touched down, in force until 03:56 UTC.

The county was under a tornado watch, issued at 02:43 UTC and running to 07:07 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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 01:01 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 Springfield radar (KSGF), 102 km away, was scanning. The volume nearest the touchdown began at 03:26 UTC.

54 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.
