This storm is known to have initiated the unforgettable series of events of 4 May, 2003. This classic supercell rapidly developed over Montgomery County, Kansas, eventually moving into southwestern Crawford County, Kansas where it spawned a very large and destructive tornado. This tornado laid out a path of destruction for 27 miles of farm land and small communities through Crawford County. This event also claimed three lives and injured 20 in eastern sections of the county, where the tornado had strengthened to F-4 status. The tornado continued on the ground into Barton County, Missouri.Sharon Lasbrook age 48, was deceased from being thrown out of her mobile home and into a field. Her home was completely disintegrated by the twister.George Bolte age 68, was taking cover in his manufactured home and laying over his wife to protect her from flying debris. While saving her life, he was deceased from the debris.Josephine Maghe age 87, was taking cover within her frame home as the tornado arrived. She was deceased from being struck into the ground.

An F-4 tornado tracked over the Kansas-Missouri state line and into west central Barton County. The tornado destroyed several farm houses and outbuildings prior to dissipating one mile north of Liberal. Ten injuries and one fatality can be accounted for from this large tornado. Rex Smith age 88, was in his frame house two miles west of Liberal when the tornado approached. He was deceased from flying debris. While this tornado was dissipating, a second tornado had formed one mile east of Liberal. This feature then tracked 23 miles through mainly rural farm land of central and northeast Barton County, and eventually through Cedar, Polk, Hickory, and Dallas counties. Altogether there were approximately 50 homes and outbuildings that were destroyed from the twisters.

The deaths

4 direct deaths are recorded for this tornado, each with what Storm Data knows of it.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

23 minutes of warning. NWS ICT issued a tornado warning for this county at 21:12 UTC, 23 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 High Risk, with a 0.25 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 20:19 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.

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.
