Areas affected...portions of coastal North Carolina

Concerning...Severe potential...Watch unlikely 

Valid 071520Z - 071745Z

Probability of Watch Issuance...20 percent

SUMMARY...A brief tornado cannot be ruled out through early
afternoon. A WW issuance is not currently expected.

DISCUSSION...Tropical Storm Debby continues to meander off of the
coastline of the Carolinas as widespread rain/clouds from outer rain
bands continue to overspread inland areas. Regional VADs
(particularly LTX) depict sizable low-level hodographs and nearly
300 m2/s2 0-1 km SRH. However, despite mid to upper 70s F
contributing to over 1000 J/kg SB/MLCAPE, boundary-layer lapse rates
remains quite poor (both the 12Z MHX observed sounding and 15Z
mesoanalysis show 5 C/km in the 0-3 km layer). Given the favorable
low-level shear, a brief tornado cannot be completely ruled out,
especially over far southern NC, where some breaks in the clouds
were noted. Nonetheless, overall tornado coverage is expected to be
sparse, and a WW issuance is not currently anticipated.
