Mesoscale Discussion 2326

1205 PM CST Sun Dec 10 2023
Areas affected...Portions of eastern NC...northeastern SC...and
southeast VA
Concerning...Severe potential...Watch possible
Valid 101805Z - 102030Z
Probability of Watch Issuance...60 percent
SUMMARY...Monitoring portions of eastern NC, northeastern SC, and
southeastern VA for a gradual increase in severe-storm potential
this afternoon.
DISCUSSION...Latest radar data across portions of eastern NC,
northeastern SC, and the coastal waters indicates northward-moving
clusters of mainly disorganized storms. This activity is likely
being driven by low/midlevel warm advection and coastal convergence
amid strong low-level south-southwesterly flow (per MHX/LTX VWP
data). Through the afternoon, continued boundary-layer positive
theta-e advection should destabilize the coastal air mass amid
filtered diurnal heating in cloud breaks. The increasing
surface-based instability (albeit weak), coupled with strengthening
low/deep-layer shear -- characterized by increasingly large
clockwise-turning low-level hodographs -- will favor a gradual
increase in severe-storm potential through the afternoon. A couple
tornadoes and damaging winds will be the main concerns.
