During the afternoon and early evening of May 26, 2024, ten tornadoes touched down in the St. Louis metropolitan area and southwest Illinois from a mix of supercells and QLCS modes. This occurred alongside numerous reports of large hail of up to 2.5 inches in diameter and damaging winds of up to 81 mph. Thankfully, there were no reported injuries or fatalities with these thunderstorms.

A tornado touched down at the intersection of Highway 141 and Fiedler Lane blowing down a traffic light. As it tracked to the northeast it caused some minor siding damage to one house, uprooted at tree and blew down several large tree limbs. Further northeast it uprooted a large tree that landed on a house causing some porch and moderate roof damage. The tornado then lifted and dissipated. Overall, the tornado was rated EF0 with a path length of 0.21 miles and a max path width of 100 yards. No deaths or injuries were reported.

35 minutes of warning. NWS LSX issued a tornado warning for this county at 22:09 UTC, 35 minutes before the tornado touched down, in force until 23:00 UTC.

The county was under a tornado watch, issued at 21:05 UTC and running to 00:24 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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 20:20 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 St Louis radar (KLSX), 33 km away, was scanning. The volume nearest the touchdown began at 22:46 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.
