Significant damage at Great Bend Airport. Hangars were unroofed and an unspecified number of aircraft were overturned. This proved to be an anxious moment for Great Bend! After causing extensive damage to the airport, the tornado was moving toward the city when it lifted. The funnel passed directly over the city at tree-top level. The funnel subsequently touched down east of Great Bend, striking two farmsteads five miles east of Barton County Community College. (See 1544 CST entry for details.) (Narrative courtesy Great Bend Tribune.)

Extensive damage to two farmsteads. The damage survey revealed the tornado achieved a strong F-1 rating, meaning it's rotational velocities were around 110 mph. (Narrative courtesy of Wichita Eagle and Hutchinson News.)

Remained in the country.

7 minutes of warning. NWS ICT issued a tornado warning for this county at 20:57 UTC, 7 minutes before the tornado touched down, in force until 21:45 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 Slight Risk. The outlook in force was issued at 19:45 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.

5 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.
