A supercell thunderstorm that produced a tornado in Newton County, spawned a large tornado in Lawrence County approximately one mile north of Verona. The tornado damaged 46 structures and destroyed 21. One fatality occurred from flying debris striking an elderly man in his frame home north of Marionville. This tornado basically followed a similar path that another F-3 tornado tracked along during the 4 May 2003 tornado outbreak.

This tornado is a continuation of the Lawrence County tornado. Significant structural damage occurred across the Christian County panhandle in a rural area between Billings and Clever. This area was also heavily impacted by the 4 May 2003 tornado. A subdivision with solid well built homes northwest of Nixa was directly impacted by the tornadoes destruction. 138 structures were damaged while 127 structures were destroyed. The tornado weakened as it tracked into southern Greene County, impacting southern sections of the city of Springfield.

This tornado is a continuation of the Christian and Lawrence County tornado. The tornado tracked across extreme southern Springfield causing damage to approximately 27 homes. None of the homes or structures were completely destroyed. The tornado quickly became weaker and only produced intermittent tree damage from Highway 65 over to the Webster County line.

The county was under a tornado watch, issued at 02:43 UTC and running to 08:38 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 High 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.

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.
