A closed upper low emerged out of the Rockies and into the Central Plains during the afternoon and evening hours of March 21st, with the attendant upper trough swinging east through Central Texas and Oklahoma. Strong southerly low level winds allowed for the rapid return of warm, moist, and unstable north behind a warm front which lifted north through East Texas and North Louisiana. Large scale forcing began to increase across Northern and Central Texas during the evening, with showers and thunderstorms becoming numerous across this area which spread into East Texas and North Louisiana during the late evening through the early morning hours of the 22nd. Given the extent of forcing within the unstable air mass in place, severe thunderstorms developed over North-central Texas and spread into East Texas, resulting in numerous reports of damaging winds, large hail, and even isolated tornadoes. Redevelopment of these storms continued overnight as well over the same areas of East Texas and Northwest Louisiana, which resulted in instances of flash flooding as well, as widespread rainfall amounts of 3-6 inches fell over these areas. These storms diminished during the early morning hours of the 22nd with the passage of a cold front through the region.

A weak EF-1 tornado with estimated maximum winds near 90 mph touched down on Blocker Road and snapped/uprooted several softwood trees. The tornado then crossed County Roads 1320, 1312, and 1202 (Old Town Road) before lifting. Multiple trees were snapped and uprooted in a convergent pattern along its path.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a tornado watch, issued at 01:10 UTC and running to 06:58 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 Enhanced 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 00:52 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 Shreveport radar (KSHV), 37 km away, was scanning. The volume nearest the touchdown began at 05:51 UTC.

35 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.
