Thunderstorms developed near a weak surface boundary over the southern and central South Plains during the afternoon hours of the 2nd. Steep low level lapse rates allowed for enhanced stretching beneath thunderstorm updrafts in vicinity of the boundary, and at least one landspout tornado developed. No damage was reported.

Numerous reports were received of a tornado in extreme northwestern Lynn County. The tornado was highly visible from Lubbock, Wolfforth, and even from portions of Terry County. ||A Texas Tech University West Texas Mesonet meteorologist initially witnessed a developing funnel cloud to the distant south from Reese Center at 12:49 CST. A ground circulation was first seen at 12:51 CST, and the tornado reportedly dissipated rapidly at 12:55 CST. ||The tornado remained over open fields southwest of the intersection of Farm to Market Roads 179 and 41 (intersection actually in extreme southwestern Lubbock County). A Wolfforth city employee observed the tornado from just south of Farm to Market Road 41 west of that intersection, and reported that it was south of his location, in extreme northwestern Lynn County. Radar additionally indicated a weak convective shower there. Initial reports indicated that debris was spotted in the tornadic circulation, but no damage was discovered by local authorities.

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

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 General Thunderstorms Risk. The outlook in force was issued at 16:21 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.

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.
