Day 2 Convective Outlook

1238 AM CDT Sat Oct 07 2023

Valid 081200Z - 091200Z

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

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

....Synopsis and Discussion...
A large, closed upper cyclone will encompass much of the eastern
CONUS and Canada on Sunday. Meanwhile, upper ridging will persist
over the Rockies and Southwest as another 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 Sunday, with a few
exceptions.

Beneath the cold-core upper low, low-topped convection could produce
occasional lightning flashes as it moves across Lake Erie/Ontario
into adjacent portions of western NY and vicinity. Isolated
thunderstorms may occur across parts of south FL and the Keys Sunday
afternoon/early evening along and south of the cold front. But, with
negligible large-scale ascent forecast, any convection which can
develop should be tied to either modest low-level convergence along
the front or mesoscale sea breeze boundaries. Finally, convection
may also develop across parts of AZ and western NM Sunday afternoon,
mainly along/near the Mogollon Rim.
