A stalled frontal boundary was draped across portions of Kansas during the day on May 7th, 2019 ahead of an approaching storm system. Widespread showers and thunderstorms with very heavy rainfall developed across the area. These storms inundated areas that were already saturated from recent rainfall resulting in widespread flooding across south central Kansas. ||Significant flash flooding occurred during the evening and overnight of May 7th, 2019 into the early morning hours of May 8th. The most significant flash flooding occurred during the early morning hours of May 8th, when areas southeast of Wichita picked up between seven and ten inches of rainfall in a 24 hour period. Numerous water rescues took place across Mulvane, Augusta, Wellington and Rose Hill. In addition, several miles of the Kansas Turnpike was closed south of Mulvane due to the Slate Creek reaching record levels. Closing this much of the Kansas Turnpike due to flooding hasn't happened in over 30 years.

Damage to trees were noted along the path.

1 minute of warning. NWS ICT issued a tornado warning for this county at 04:18 UTC, 1 minute before the tornado touched down, in force until 04:48 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, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 01:03 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 Wichita radar (KICT), 47 km away, was scanning. The volume nearest the touchdown began at 04:21 UTC.

22 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.
