Snow possible for parts of the South

Monitoring the potential for a light rain/snow mixture across parts of Tennessee, Mississippi, Alabama & Georgia late-Thursday into early-Friday. An upper-level trough, which helped spark severe thunderstorm on Wednesday, will move across the mid-South on Thursday.

On the backside of this trough, atmospheric temperatures (from the surface to where the jets fly) will plummet throughout Thursday. This will help set the stage for temperatures supportive of wintry precipitation. While the colder air will also be drier, a secondary area of enhanced-lift will dive southeast, placing the region in a favorable region for light precipitation to develop. While moisture is limited, guidance indicates some mid-level moisture moving in with this area of lift, which should be enough to allow a rain/snow mixture to reach the surface.

Marginal surface temperatures & meager moisture will prevent major accumulations. However, light accumulations (generally under 1/2″) are possible but a few areas may see up to 1″. Higher amounts possible on the west-facing slopes of the higher terrain in Tennessee & North Carolina. This is an evolving forecast so keep checking back for updates!
