1217 PM CDT Sat Oct 07 2023

Valid 081200Z - 091200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

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

....Synopsis...
A large upper low will encompass much of the eastern
CONUS and Canada on Sunday. Meanwhile, upper ridging will persist
over the Rockies and Southwest as an upstream upper trough
approaches the Pacific Coast. At the surface, appreciable low-level
moisture will remain confined along/south of a cold front forecast
to be located over the Gulf of Mexico and south FL. Thunderstorm
potential appears limited for a large majority of the CONUS on
Sunday.

Exceptions will be in the vicinity of the upper low over the lower
Great Lakes/northeast, where very modest destabilization to east of
Lakes Erie and Ontario could produce isolated lightning flashes with
deeper updrafts.  Widely scattered thunderstorms will also be
possible over South Florida and the Keys in the vicinity of a
slow-moving front, where diurnal heating of a moist low-level air
mass (lower 70s dew points) should contribute to sufficient
destabilization.  Isolated storms may also form over portions of
AZ/southwest NM along the Mogollon Rim.
