Say it ain’t (Southeast) SNOW!
Light snow is possible for parts of the Southeast on Saturday. A rather potent upper-level trough will dig southeast into the Tennessee Valley on Saturday. A piece of energy (lift) will rotate into the Southeast on Saturday via this trough, which will provide the lift needed for precipitation to develop on Saturday in the colder airmass. Precipitation will fall in the form of rain early Saturday before colder temperatures aloft and at the surface filter in.
These colder temperatures will allow rain showers to transition to snow showers across eastern Tennessee, far northeastern Alabama, northern Georgia and western North Carolina. There may even be a flake or two across far western parts of upstate South Carolina. The best window for snow showers will be Saturday afternoon into Saturday evening. The snow chances will hang on just a touch longer for the highest terrain of far eastern Tennessee & western North Carolina thanks to a touch of upslope.
Light snow accumulations are possible in northern Georgia with the best chance for accumulations above 2,000′. Up to 1″ possible above 2,000′ while 2″ possible above 3,500′. The higher snow totals will occur in the mountains of eastern Tennessee and western North Carolina where 4-8″ will fall above 5,000′. Lower elevations will see lesser amounts in Tennessee; 1″ above 2,000′ with 2-3″ above 3,000′.
No winter weather products are in place at this time but a Winter Weather Advisory may be needed for the higher elevations of eastern Tennessee and western North Carolina by Saturday.
