Pretty clever writing from KATL

Locally, the strong southerly jet ahead of the dominant low-pressure
system should provide enough lift to form some scattered light
showers ahead of the main storm system from late afternoon through
midnight. Just after midnight, an unorganized wave (or possibly
multiple waves) of storms is expected to push into the forecast area
out of Alabama. There will be enough lift from the low- and mid-
level jet for some isolated to scattered thunderstorms to form, and
while storms are expected to generally be weak with minimal upper-
level instability available, momentum transfer from a 40-50kt jet at
850hPa is a concern. The airmass in the lower kilometer will be
stable, but not by much, and therefore any water-loaded downdrafts
will have potential for strong winds gusts to occur. Even outside of
the storms, wind gusts could be up to 20-30 mph given the strong low-
level jet near the ground so be sure to secure any holiday
decorations that may be out, as inflatable Santas may take flight

tonight, which would be about a month earlier than expected.
