Widespread severe thunderstorms, organized along a passing cold front, impacted much of Oklahoma and western-north Texas on the afternoon and evening of the 3rd. In addition to reports and observations of thunderstorm wind damage and large hail, six tornadoes occurred across the WFO Norman Forecast Area. Flash flooding also occurred during the evening hours across southeastern Oklahoma due to repeated rounds of heavy thunderstorms.

A tornado developed near County Road 3210 about 4 miles east-southeast of Katie, and moved north-northeast. Near the beginning of the path, emergence management officials reported the east-facing garage door of a home was damaged and significant tree damage.

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 19:55 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 Norman radar (KTLX), 84 km away, was scanning. The volume nearest the touchdown began at 22:36 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.
