An anonymously strong upper level system allowed everything to come together at the surface to produced what is perhaps the biggest tornado outbreak to ever occur in the Dodge City CWA! Fifty-five tornadoes were documented during that afternoon and evening! Some of the tornadoes were very large and damaging. The character of the supercell thunderstorms that day had similarities to the storms that produced the Greensburg tornado a little over a year after. In fact there was one tornado that was just as large and perhaps could have been just as damaging that was headed towards the small Kiowa county town but fortunately turned and dissipated.

This was a large tornado that produced EF2 damage. It turned northwest towards the end of its life cycle but dissipated before reaching Arnold. Damage was done to trees, large power poles, a large tank, a barn and hay bales.

This was a satellite tornado that moved south on the west side of its large parent tornado. EF2 damage was done to trees (uprooted).

This tornado caused EF3 damage to trees and an old stone home. A farm implement was carried 1/2 mile south of it's original starting point. EF3 damage was also done to trees. Another home sustained EF1 damage. There were numerous power poles taken down and at least 5 head of cattle perished in the tornado. The tornado moved into Trego county at 19:42 CDT.

24 minutes of warning. NWS DDC issued a tornado warning for this county at 23:43 UTC, 24 minutes before the tornado touched down, in force until 00:30 UTC.

The county was under a tornado watch, issued at 19:16 UTC and running to 01:52 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 20:01 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 Dodge City radar (KDDC), 89 km away, was scanning. The volume nearest the touchdown began at 00:07 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.
