Visit our Event Page for a more detailed look at the Severe Weather that occurred at the end of December/Beginning of January.

 

December 11th Tornado and Wind Damage in Central GA:

A line of showers and scattered thunderstorms spawned a brief tornado over rural Wilkinson County near KJGX radar (north of I-16). A tornado touched down over south-central Wilkinson County within a small area of showers and storms out ahead of a cold front. A brief, but discrete mini-supercell was imbedded in that line. This tornado was determined to be an EF-0 with estimated peak wind speeds of 70 mph. For more information on this storm visit our Public Information Statement.

Local Storm Reports

 

December 29-30th Central Georgia Severe Weather Outbreak:

A stationary front stalled out over northern Alabama and into NW Georgia. Unseasonably warm temperatures flooded into north and central Georgia. A strong low-level jet allowed a QLCS that formed later in the afternoon to intensify, creating a number of bowing segments that caused some extensive wind damage. Tornadoes were confirmed in Hall County and Pulaski County. Out in front of this line of storms across central Georgia, a few discrete storms aided by 30-40kts of bulk sheer and a low level jet took on supercell qualities. Numerous reports of quarter sized hail was received in and around the Columbus area.

December 31st Low Precipitation Supercell Tornadoes:

On New Years Eve, the Metro Atlanta area experienced a relatively rare phenomena for the east side of the Mississippi river. A favorable environment for Low Precipitation (LP) Supercells including low atmospheric moisture and strong mid-level winds came together resulting in two confirmed tornadoes. As the name entails, LP supercells are strong storms that produce much less precipitation then the standard Classic Supercell or High Precipitation Supercell that Georgia often sees during the spring severe weather season. For more information on these storms, please see out Public Information Statements for Carroll County and Newton County.
