A dryline was the main focus for storm development during the afternoon of the 2nd as a compact upper wave crossed the area. Numerous storms led to reports of hail, high winds, and a few tornadoes through the afternoon and evening.

This tornado developed to the west of the Cimarron River near South Union Road and 104th Street. It moved to the east-northeast passing just south of the city limits of Ripley and dissipating about 3 miles east of Ripley. The tornado caused damage to trees, farm buildings and a few mobile homes.

6 minutes of warning. NWS OUN issued a tornado warning for this county at 23:20 UTC, 6 minutes before the tornado touched down, in force until 23:45 UTC.

The county was under a tornado watch, issued at 19:03 UTC and running to 00:26 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 Moderate Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:20 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), 82 km away, was scanning. The volume nearest the touchdown began at 23:26 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.
