Mesoscale Discussion 1841 NWS Storm Prediction Center Norman OK 0757 AM CDT Tue Aug 06 2024 Areas affected...Parts of coastal SC/NC Concerning...Tornado Watch 603... Valid 061257Z - 061430Z The severe weather threat for Tornado Watch 603 continues. SUMMARY...Some tornado threat will persist through the morning. DISCUSSION...Early visible satellite imagery depicts widespread cloudiness across coastal SC/NC, which will tend to inhibit destabilization through the morning. However, dewpoints in the mid/upper 70s F across near-coastal areas will continue to support MLCAPE of around 500 J/kg (as noted on the 12Z MHX sounding). This will be sufficient for maintenance of at least transient small supercell structures, given the presence of 0-1 km SRH of 150-250 m2/s2 in the northeast quadrant of Tropical Storm Debby. The stronger wind field will gradually spread northeastward through the day, and some tornado threat may eventually spread out of WW 603 into a larger part of eastern NC, where somewhat stronger heating may occur through the morning. Eventual watch issuance north of WW 603 is possible if observational trends warrant. ..Dean/Edwards.. 08/06/2024 ...Please see www.spc.noaa.gov for graphic product...
