Another strong short wave, the second in three days, rotated through a large and deep upper-level trough over the eastern U.S. A deep surface low and strong cold front moved through the state combining with moderate instability and strong low-level shear to produce another round of widespread severe weather across north and central Georgia, including several tornadoes.

A National Weather Service survey team found that an EF0 tornado with maximum wind speeds of 70 MPH and a maximum path width of 150 yards briefly touched down southwest of Plains along Highway 45 snapping a few trees. The tornado moved northeast crossing N. Carter Fishpond Road and Chavers Drive uprooting a few trees. The tornado continued northeast crossing Highway 308 south of Plains, uprooting a few more trees and causing minor roof damage to a few homes before ending shortly after crossing Wise Road. No injuries were reported. [04/05/17: Tornado #4, County #1/1, EF-0, Sumter, 2017:063].

46 minutes of warning. NWS FFC issued a tornado warning for this county at 16:54 UTC, 46 minutes before the tornado touched down, in force until 17:45 UTC.

The county was under a tornado watch, issued at 16:54 UTC and running to 00:00 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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 16:29 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.

23 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.
