Mesoscale Discussion 1533
NWS Storm Prediction Center Norman OK
1104 AM CDT Thu Jul 21 2022

Areas affected...portions of Georgia into eastern South
Carolina/southeastern North Carolina

Concerning...Severe potential...Watch unlikely

Valid 211604Z - 211800Z

Probability of Watch Issuance...20 percent

SUMMARY...Storm development will continue across portions of Georgia
and into the eastern South Carolina vicinity.  Gusty/locally
damaging winds will be possible with the strongest storms, but WW
issuance is not anticipated in the short term.

DISCUSSION...Latest visible satellite loop shows an outflow
extending from northwestern Georgia east-southeastward across
central Georgia, and then eastward/northeastward across eastern
South Carolina.

Substantial cloud cover north of the outflow is maintaining a more
stable environment, but heating of the moist boundary layer near and
south of the boundary is contributing to 2000 to 2500 J/kg
mixed-layer CAPE.  This is supporting renewed convection along the
outflow, the strongest of which are indicated over northwestern
Georgia, where low-level southeasterly flow impinging on the
boundary is focusing ascent.

Despite ample instability and the slowly advancing outflow providing
a focus for convective redevelopment, flow aloft remains modest,
with westerlies generally at or below 15 to 20 kt through the lowest
3 to 4km.  As such, while a local risk for gusty winds/tree damage
will exist with a few stronger cells, overall risk does not appear
to warrant WW consideration at this time.
