A lone supercell thunderstorm moved from south central Kansas into central Kansas during the afternoon and evening of April 19th, 2023. The cyclic storm produced very large hail up to 4 inches in diameter and numerous tornadoes across Chase county, Kansas. Eight tornadoes formed from the supercell with the strongest producing EF2 damage.

This is the first tornado which a storm survey revealed that an outbuilding was thrown 250 yards. Additional outbuildings were collapsed on site. The roof of a silo was removed from the top, and walls at the base were pushed in. This was rated an EF1 tornado.

The second tornado of the event was found following assessment of drone footage courtesy of Chase County Sheriff. This brief tornado damaged two farm outbuildings with parts of the roof torn off and was rated an EF0.

This is the third tornado which initially caused the loss of roof material on an outbuilding. The tornado crossed U.S. Highway 50, and a semi was blown over resulting in one injury. Several small road signs were taken out. A one to two foot diameter tree was snapped before the tornado lifted. This tornado was rated an EF0.

The was the fifth tornado of the event. It tracked just north of Chase County Lake and damage was limited to trees and small outbuildings.

The sixth tornado produced by the supercell tracked across the town of Cottonwood Falls producing EF1 damage, mainly to trees and minor damage to roof structures.

This was the seventh tornado of the event. Damage was limited to trees and siding of homes.

This was the eighth tornado documented by the NWS Wichita damage Survey Team. This tornado mainly produced EF0 damage to mainly trees. There was one minor injury close to the initial touchdown along Highway 50, when a car was thrown 30 yards off the highway. The person was treated and released.

12 minutes of warning. NWS ICT issued a tornado warning for this county at 01:06 UTC, 12 minutes before the tornado touched down, in force until 01:45 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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 00:48 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.
