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.=20

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.
