Day 3 Convective Outlook 
NWS Storm Prediction Center Norman OK
0225 PM CDT Thu Sep 12 2024

Valid 141200Z - 151200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Saturday.

...Southeast...
The remnants of TD Francine will continue to weaken across the
Southeast on Saturday. A moist and unstable airmass should be
present across northern Florida and into southern Georgia and
southeast Alabama. This will likely result in scattered to
widespread thunderstorms, particularly during the afternoon.
However, the primary threat from these storms should be heavy rain
as very weak lapse rates and only marginal deep-layer shear will
likely result in mostly sub-severe convection. 

...Central to Northern Plains...
Widely scattered thunderstorms are possible along the dryline from
the central Plains to the northern Plains on Saturday. Initially,
low-level moisture will be limited, but better moisture will advect
ahead of the dryline by late afternoon to early evening. This may be
sufficient for a few thunderstorms to develop along the dryline as a
weak mid-level shortwave trough moves into the Plains. The
co*bination of isolated storm coverage and only marginal deep-layer
shear precludes the need for a Marginal Risk at this time.
