3 damage points were recorded along this path by NWS AMA, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 70 mph.

• Brief tornado touchdown near Highway 54. Reported by Storm Spotter.
• Storm Chaser captured photographic evidence of tornado 2 miles south of Stratford.
• Brief tornado damaged outbuilding/fireworks stand and powerlines down on HWY 287.

Northwest flow aloft brought a round of severe convection during the evening hours of the 16th to the Texas Panhandle. As a shortwave trough moved out of Colorado, a warn front was situated across the northern and eastern Texas Panhandle. Convection developed along this front during the evening hours. The combination of marginal instability, moderate deep layer shear, and additional turning of low level winds in the vicinity of the front allowed for brief tornadoes to develop. As the evening progressed, the outflows from storms pushed the warm front southward across the Panhandle. Severe convection ended around 9 PM CST as storms transitioned to heavy rain production.

A discrete supercell developed over Sherman County during the evening hours of the 16th. As the storm moved near the town of Stratford (Sherman County), a trained storm spotter captured a brief tornado on video. The tornado lasted less than a minute and was estimated to have 70 mph wind speeds. The storm continued to move southward after producing this tornado. No damage was reported with this tornado.

A discrete supercell developed over Sherman County during the evening hours of the 16th. The storm produced a second brief tornado on the south side of Stratford (Sherman County). A storm chaser captured multiple images of the tornado, and it caused damage to an outbuilding and downed power lines along US Highway 287. The estimated max wind was 70 mph and the storm which produced the tornado continued to move south across the county.

4 minutes of warning. NWS AMA issued a tornado warning for this county at 00:04 UTC, 4 minutes before the tornado touched down, in force until 00:30 UTC.

The county was under a severe thunderstorm watch, issued at 20:36 UTC and running to 01:53 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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:49 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.
