A very moist and convergent zonal flow pattern set the stage for several rounds of severe weather across the southern portions of central Alabama on March 3rd/4th. A weak cold front pushed south of I-20 on March 3rd and triggered a cluster of strong to severe storms, including a few weak tornadoes. Another round of severe storms impacted areas south of I-85, producing high winds.

National Weather Service meteorologists surveyed damage in eastern Hale County and determined that it was consistent with an EF0 tornado, with maximum winds near 75 mph.||The tornado touched down near Royal Estates Drive, just southwest of the town of Greensboro. The tornado tracked east-northeast where it snapped and uprooted numerous trees near a ballpark on Highway 69. Nearby homes suffered structural damage due to fallen trees, as well as varying degrees of minor roof and siding damage. Farther downstream, tree damage was observed on Cherokee Terrace where numerous pines were uprooted. The tornado continued east-northeast where minor structural damage was observed near Centerville Street and Avery Drive. The tornado then turned to the east and east-southeast where it uprooted several trees on County Road 7 before dissipating near Whitsitt Creek.

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, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 05:56 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.
