CORRECTED FOR WORDING

The severe weather threat for Tornado Watch 603 continues.

SUMMARY...An isolated tornado threat continues across portions of
the coastal Carolinas in association with Tropical Storm Debby. A
few brief tornadoes may accompany the stronger storms through at
least early afternoon.

DISCUSSION...Multiple bands of stronger showers and thunderstorms
are impinging on the counties in northern SC into southern NC that
border the Atlantic in advance of the center of TS Debby, which
continues to gradually drift north-northeastward this morning. Given
poor tropospheric lapse rates and widespread, persistent cloud
cover, overall buoyancy should remain modest (i.e. 500-1000 J/kg
MLCAPE, supported mainly by mid to upper 70s F surface dewpoints).
Around 200-300 m2/s2 of effective SRH may overspread the 80+ F
surface temperatures along coastal NC later this afternoon, where a
slight uptick in tornado potential may be realized. Otherwise, a
persistent threat of a stray, brief tornado should persist while
gradually shifting northward along the NC Outer Banks through the
day.
