A strong short wave and associated surface low swept through the southern and eastern U.S. and combined with moderate instability and strong shear resulted in widespread severe weather, including numerous tornadoes, across north and central Georgia from late morning through the afternoon.

A National Weather Service survey team found that an EF1 tornado with maximum wind speeds of 90 MPH and a maximum path width of 150 yards moved east from Twiggs County into Wilkinson County west of Tarpley Road. The Tornado weakened somewhat but still snapped or uprooted a few trees. After crossing Old Macon Road the tornado ended along Knightpond Road where it briefly intensified and uprooted a few large oak trees. No injuries were reported.

A National Weather Service survey team found that the thunderstorm responsible for the EF2 tornado around Gordon in northwest Wilkinson County produced an EF0 tornado in northern Wilkinson County. The tornado touched down near the intersection of Sheppard Bridge Road and DP Carr Road and travelled northeast crossing Mt. Carmel Road and US Highway 441 before ending around the intersection of Smith Startley Road and Wriley Road. Although most of the path consisted of snapped trees, the tornado caused roof damage to a residence at the intersection of Napier Pond-|Wriley Road and Parker Hill Road. No injuries were reported.

A National Weather Service survey team found that an EF1 tornado briefly touched down in east central Wilkinson County near the intersections of Poplar Springs Church Road, Highway 112 and Club Drive. A single-wide trailer was shifted off its foundation with two people at home at the time. No injuries were reported. Another trailer had some loss of shingles and a collapsed carport. There were also nearby trees snapped. [04/03/17: Tornado #24, County #1/1, EF-1, Wilkinson, 2017:056].

16 minutes of warning. NWS FFC issued a tornado warning for this county at 18:00 UTC, 16 minutes before the tornado touched down, in force until 18:45 UTC.

The county was under a tornado watch, issued at 18:07 UTC and running to 22:09 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 Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. 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.

39 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.
