valid 211200z - 221200z
...no severe thunderstorm areas forecast...
...summary...
isolated general thunderstorms are possible saturday over the
tennessee valley to southern appalachians.
...synopsis...
a shortwave trough will exit the northeast on saturday, with a lobe
of cool air aloft extending southwestward from the tn valley into
the southeast. meanwhile, an upper high will remain situated over
az/nm and into the southern plains.
at the surface, a weak trough is forecast from the mid atlantic into
the tn valley, with surface dewpoints in the 50s to lower 60s f.
while lift will be minimal, daytime heating and sufficient
instability may support isolated thunderstorms in association with
the subtle southern wave. severe weather appears unlikely given weak
lift and marginal shear/instability.
