A upper level low developed across the far NE Texas Panhandle with an associated dryline back to the south and southwest. A jet streak working into west Texas during the afternoon helped bring strong shear throughout the column into the Panhandles. In particular, noticeable surface based directional shear right along the dry line, west winds to the west and east winds east of the dryline helped storms develop rotation along the converging boundary. Storms that developed had broad rotation along a small line of individual couplets. Some deeper cores did produce some severe hail across the northeastern Panhandles. A landspout was confirmed by spotters in far southeast Ochiltree County along with an 6 mile weak EF-1 tornado track through parts of Hemphill and Lipscomb counties.

A tornado touched down in rural Hemphill County northwest of Glazier. The tornado caused damage to trees, power poles and out building equivalent to a lower end EF1.

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

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 Marginal Risk. The outlook in force was issued at 00:59 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.

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.
