Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1040 AM CST Wed Nov 30 2022

Valid 011200Z - 021200Z

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

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

....Synopsis...
One amplified mid/upper-level trough will move eastward from the Mid
Atlantic/New England to the Canadian Maritimes on Thursday, while
another mid/upper-level trough will move into and across the western
CONUS through the period. A large surface ridge will persist from
the south-central into the eastern CONUS, while a surface cyclone
will move from the interior Northwest into the northern High Plains.

Generally dry and stable conditions will dominate over most of the
CONUS through the period. Isolated thunderstorms will be possible
across parts of south FL, within a moist and moderately unstable
environment. Cold midlevel temperatures will support weak convection
capable of sporadic lightning flashes near the OR and northern CA
coasts. Some weak elevated convection will be possible across parts
of the southern Plains into the Ozarks within a warm advection
regime, but midlevel lapse rates and buoyancy appear too weak to
support thunderstorm development. Weak convection will also be
possible across parts of the Great Basin in association with the
mid/upper-level trough passing through the region, though lightning
potential appears limited at this time.
