Mesoscale Discussion 0065
NWS Storm Prediction Center Norman OK
0347 PM CST Fri Jan 24 2020
Areas affected...central and eastern South Carolina
Concerning...Severe potential...Watch unlikely
Valid 242147Z - 242345Z
Probability of Watch Issuance...20 percent
SUMMARY...A gradual uptick in convection has been noted across
central South Carolina and eastern Georgia. The overall severe
threat, while not zero, should remain low over the next hour or two.
DISCUSSION...Radar mosaic and satellite imagery indicate gradually
developing convection resulting from convergence along a pre-frontal
wind shift located from near 30 W CLT southward to near CAE to 25 SE
AGS. This convection remains relatively shallow (evidenced by the
lack of lightning) and resides in a weakly buoyant airmass
characterized by 250-1000 J/kg MUCAPE. It is uncertain how quickly
this convection will intensify given negligible forcing aloft,
although point forecast soundings suggest that ongoing convection
will have the ability to ingest near-surface-based parcels over
time, and strong vertical shear may encourage updraft rotation with
a few cells. These trends suggest a low-end potential for isolated
damaging wind gusts and perhaps a brief tornado - especially with
cellular convection that can organize as convection shifts eastward
across the discussion area.
