MD 1044 CONCERNING SEVERE POTENTIAL…WATCH POSSIBLE FOR PORTIONS OF SOUTHEASTERN/COASTAL GA AND FAR NORTH FL
Mesoscale Discussion 1044
NWS Storm Prediction Center Norman OK
0252 PM CDT Wed Jun 14 2023
Areas affected...Portions of southeastern/coastal GA and far north
FL
Concerning...Severe potential...Watch possible
Valid 141952Z - 142145Z
Probability of Watch Issuance...60 percent
SUMMARY...An increasing threat for large hail, damaging winds, and
perhaps a couple of tornadoes may prompt watch issuance this
afternoon.
DISCUSSION...In the wake of earlier convection this morning, some
airmass recovery has occurred across parts of southeastern/coastal
GA and north FL. Recent radar imagery shows an outflow boundary from
prior thunderstorms is still continuing southward along/near the
FL/GA line. But, filtered daytime heating to the north of this
boundary has allowed surface temperatures to generally increase into
the low to mid 80s downstream of multiple supercells ongoing across
southwestern into south-central GA. There are still some concerns
about instability due to a large area of remnant stratiform
precipitation, with MLCAPE quickly dropping off with northward
extent across coastal GA into southern SC. Regardless, deep-layer
shear still appears strong enough (35-45+ kt) to support supercells.
Current expectations are for the ongoing supercells to spread
eastward over the next few hours, while posing a threat for large
hail and damaging winds. Enough low-level shear is also present to
foster low-level updraft rotation and some risk for a couple of
tornadoes. Convective trends will be monitored for possible watch
issuance this afternoon.
