Severe thunderstorms developed along a dryline and moved slowly eastward during the late afternoon and early evening hours of Sunday, May 16th. Three weak tornadoes were reported resulting in no damage. One tornado appeared to form on the dryline boundary with a sharply tilted condensation funnel stretching to an updraft base approximately 3-4 miles to the east. This landspout tornado lasted about 2 minutes and crossed Highway 27 south of Sharon Springs, but it did not hit any structures. Numerous reports of golfball to baseball size hail were received from the stronger and more organized supercell storms. Thunderstorm movement slowed during the evening as some storms backbuilt to the west. Roads in Gove and extreme southeast Logan counties were reported water covered, with a few section roads still covered with water at noon on the 17th.

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, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 20:00 UTC.

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 Goodland radar (KGLD), 119 km away, was scanning. The volume nearest the touchdown began at 23:52 UTC.

15 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.
