0806 PM CDT Thu Jun 23 2022
Areas affected...portions of central South Carolina
Concerning...Severe potential...Watch unlikely
Valid 240106Z - 240230Z
Probability of Watch Issuance...5 percent
SUMMARY...A damaging gust may accompany the leading line of a storm
cluster in central South Carolina as it interacts with a sea-breeze
boundary. A WW issuance is not expected.
DISCUSSION...A multicellular storm cluster has recently grown
upscale into a small, loosely organized MCS given recent cold-pool
mergers. A few damaging gusts have been reported in the past couple
of hours and KCAE velocity data has shown 40+ kt flow near the
gust-front leading edge about 500 ft above the ground. Surface
temperatures remain near 90 F out ahead of the cold pool, with a sea
breeze also approaching the gust front area. The remaining buoyancy
and potential cold-pool/sea-breeze merger may briefly enhance
gust-front intensity and support a damaging gust or two before
storms weaken with the onset of nocturnal cooling. The severe threat
is expected to remain brief and localized enough to preclude a
severe thunderstorm watch issuance.
