6 damage points were recorded along this path by NWS OUN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 78 mph.

• Barn damage (approx location). Barn damage and scattered metal. Debris scattered 1/4 mile or more down the highway. (per Ravia EM on Slack)
• Section of the metal roof of a mobile home removed, camper blown over and tree branches blown down. Shared images in Slack from Carter County EM.
• Pictures in slack from City of Ardmore EM.
• Windows frames removed from building.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

An intense upper-level trough impacted the WFO Norman Forecast Area during the late evening of the 3rd through the 4th. Initial thunderstorm development occurred along an attendant cold front, moving west to east across the area early in the period. These initial thunderstorms produced reports of large hail and wind damage across western Oklahoma. A few hours later, during the predawn hours of the 4th, a maturing mesoscale convective system (MCS) swept across portions of south-central into southeastern Oklahoma, producing several tornadoes and widespread damaging winds. ||Finally, during daytime hours on the 4th, a strong pressure gradient and low-level jet axis promoted a widespread synoptic high wind episode across the forecast area. As a note, the first, last and highest magnitude wind gusts are those included in this episode for a particular zone (county).

A tornado developed east of Newport Road and Cardinal Road and moved north-northeast. At least three small homes were severely damaged. Three injuries were reported from one of these homes.

This tornado developed on the northern edge of the community of Gene Autry where a mobile home suffered roof damage and a camper was blown over. The tornado moved east-northeast crossing State Highway 53 and moving into the southern portion of Ardmore Municipal Airport. A barn was damaged along Highway 53, and windows were damaged in on outbuilding on the airport grounds.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

The county was under a tornado watch, issued at 10:18 UTC and running to 11:37 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 Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 06:00 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 Norman radar (KTLX), 118 km away, was scanning. The volume nearest the touchdown began at 10:43 UTC.

36 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.
