Cooler temperatures have replaced the warm temperatures that dominated the southeast over the past several days. These cooler temperatures will help set the stage for the potential for a few areas to see frozen precipitation late this weekend. A potent disturbance will traverse towards southeast into the region due to the favorable upper-level flow. This clipper-like disturbance will generate enough lift for light precipitation to develop during the day on Sunday and into Sunday night.
Looking at modeled soundings for this timeframe, it is possible the precipitation may be a rain/snow mixture before changing over to all snow later in the day on Sunday. It should be noted, while this clipper will have strong lift associated with it, the moisture at the low-levels will be significantly lacking. This will keep precipitation light in nature. The lack of low-level moisture and marginal surface temperatures should keep accumulations light.
The best chance for snow will occur across Tennessee, northern Alabama, and northern Georgia on Sunday into Sunday night. I will keep a close eye on this system, and have an accumulations map (even though any accumulations should be minimal) by Saturday.
