The National Weather Service office in Peachtree City has put out a preliminary frost/freeze warning for Monday morning. You can follow more information at http://www.weather.gov/ffc/.
If you are in far northeastern Georgia, then you are actually in the Greenville-Spartanburg NWS office’s region and you can get information from them at http://www.weather.gov/gsp/. If you are farther south towards Augusta, then you are in the zone for Columbia SC and can get information at http://www.weather.gov/cae/. They both have their own criteria for frost warnings, so you may see slightly different information coming from them. Confusing, isn’t it?
