Snow will be flying in the air this afternoon as a very cold upper level disturbance passes across Middle Tennessee.
There could be occasional "bursts" of moderate to heavy snow that could easily put a dusting on the ground in most areas. There could be isolated areas with higher amounts.
In our eastern counties on and adjacent to the Plateau there could be an inch, maybe two.
This upper level disturbance will have temperatures as low as -13° at 18,000 ft. while temps at the surface will be in the mid 30s.
This will produce "convective" type snow showers. That word is usually used for summer thundershowers, but it all has to do with the difference in temperature from the surface to aloft.
DRIVING: Temperatures should stay a few degrees above freezing until right around sunset. After that there could be some slick spots developing, especially on bridges and overpasses, though the snow will taper off this evening.
