Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1109 AM CST Sat Dec 02 2023

Valid 031200Z - 041200Z

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

....SUMMARY...
Severe-thunderstorm potential appears low on Sunday.

....Synopsis...
A deep upper-level trough will cover much of the central/eastern
CONUS on Sunday. A strong embedded shortwave trough will move from
the mid MS Valley toward the lower Great Lakes region through the
day. A surface low will deepen and move northeastward over the lower
Great Lakes in conjunction with this shortwave, with secondary
cyclogenesis expected off of the Mid Atlantic coast. A cold front
will move through parts of the Northeast, OH Valley, Mid Atlantic,
and Southeast.

Convection may persist through the day across parts of the Southeast
and FL Peninsula, in advance of the cold front. With the primary
shortwave trough and related ascent ejecting well north of the
region, storms are expected to remain rather isolated, weak, and
disorganized, despite the presence of favorable deep-layer shear.

Farther north, low-topped convection may develop during the
afternoon from eastern OH into western PA/NY, in association with
the shortwave trough and related surface low and cold front.
Buoyancy is expected to remain quite weak, but cold temperatures
aloft and relatively strong low/midlevel flow could support small
hail and gusty winds with the strongest convection.
