Day 2 Convective Outlook 
NWS Storm Prediction Center Norman OK
1220 PM CDT Sat Sep 07 2024

Valid 081200Z - 091200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The organized severe-thunderstorm threat is expected to be low on
Sunday.

...Synopsis...
A deep trough is forecast to move eastward across eastern Canada and
the northeast CONUS on Sunday, as an embedded mid/upper-level
cyclone moves across parts of Quebec, New Brunswick, and northern
New England. To the west, a midlevel shortwave trough will move
across the interior Northwest, to the north of a mid/upper-level
ridge. A surface ridge covering much of the eastern CONUS will
prevent return of richer low-level moisture from near the Gulf
Coast. This will limit destabilization and organized severe
potential across most of the CONUS.

Thunderstorms will be possible from the Carolinas/Georgia to the
immediate Gulf Coast, where richer moisture will persist near and
north of a surface front. A few strong storms may develop across the
central/northern FL Peninsula, where the relative best overlap of
instability and modest flow aloft is currently forecast. Weak
convection with sporadic lightning flashes could move across parts
of the Great Lakes, in conjunction with a pocket of cold
temperatures aloft. Isolated to scattered high-based convection will
be possible from the central High Plains into parts of the
central/southern Rockies, Great Basin, and Southwest, which may
produce locally strong gusts. Some strong-gust potential could also
acco*pany isolated storm development across the interior Northwest,
in association with the shortwave trough moving across the region.
