Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1200 AM CST Sat Jan 07 2023

Valid 081200Z - 091200Z

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

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

....Synopsis and Discussion...
An upper trough will move eastward from the lower/mid MS Valley
across the eastern CONUS on Sunday. A weak surface low centered over
the TN Valley Sunday morning should develop towards the Mid-Atlantic
through the period. Low-level moisture return ahead of a
southeastward-moving cold front will likely remain limited across
coastal TX into the lower MS Valley and Southeast. Related
instability is also forecast to be quite weak, with low potential
for robust convection over land. Still, general thunderstorms should
be ongoing Sunday morning in a modest low-level warm advection
regime from parts of coastal/southeast TX into the lower MS and TN
Valleys along/near the cold front. This activity should generally
move offshore and/or weaken with eastward extent through the day. A
low chance for thunderstorms appears possible over the Outer Banks
of NC Sunday night into early Monday morning.

Isolated thunderstorms may also occur over portions of CA and
coastal OR, mainly Sunday morning. This low-topped convection will
largely be aided by strong ascent and cool mid-level temperatures
associated with another shortwave trough moving quickly
east-northeastward over the western CONUS.
