965 ACUS11 KWNS 302224 SWOMCD SPC MCD 302224 SCZ000-302330- Mesoscale Discussion 1499 NWS Storm Prediction Center Norman OK 0524 PM CDT Sun Jun 30 2024 Areas affected...portions of central into southern South Carolina Concerning...Severe potential...Watch unlikely Valid 302224Z - 302330Z Probability of Watch Issuance...5 percent SUMMARY...A couple of strong/damaging gusts (45-55 mph) may occur in wet downbursts with the stronger storms. A 60+ mph gust cannot be ruled out, but the severe threat should be too isolated to warrant a Severe Thunderstorm Watch issuance. DISCUSSION...Cold pool mergers are occurring with congealing multicellular storms over central SC, and these storms are progressing southward amid a highly buoyant airmass. Over 2500 J/kg MLCAPE precedes the storms, which should foster continued propagation of strong updrafts on the leading edge of the southern moving cold pool. Wet downbursts may accompany the stronger storm cores, with damaging gusts possible. Nonetheless, vertical wind shear is weak, so the overall severe threat should be sparse, precluding a Severe Thunderstorm Watch issuance. ..Squitieri.. 06/30/2024 ...Please see www.spc.noaa.gov for graphic product...
