AREAS AFFECTED...PORTIONS OF THE SOUTHEAST
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 131907Z - 132130Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...WIDELY SCATTERED THUNDERSTORMS WILL BRING A LOCALIZED RISK
FOR DAMAGING DOWNBURST WINDS. WATCH ISSUANCE IS NOT ANTICIPATED.
DISCUSSION...LATEST SURFACE OBSERVATIONS DEPICT A HOT, HUMID AIR
MASS IN PLACE ACROSS THE SOUTHEASTERN U.S., WITH TEMPERATURES IN THE
MID-TO-UPPER 90S F AND DEWPOINTS IN THE UPPER 60S NOTED ALONG THE
ATLANTIC COAST. SURFACE CONVERGENCE ALONG THE SEA BREEZE AND A OF A
ROUGHLY WEST-EAST ORIENTED STATIONARY BOUNDARY IS SUPPORTING
ISOLATED THUNDERSTORM DEVELOPMENT AS OF 19 UTC, WITH ADDITIONAL
AGITATED CUMULUS NOTED ON VISIBLE SATELLITE IMAGERY. AS THUNDERSTORM
COVERAGE EXPANDS THROUGH THE AFTERNOON (PARTICULARLY WHERE LOW-LEVEL
CONVERGENCE MAXIMIZES OVER NORTHEASTERN SC AND SOUTHEASTERN NC),
STEEP LOW-LEVEL LAPSE RATES AND HIGH PWAT CONTENTS (1.75-2.0") WILL
FAVOR THE POTENTIAL FOR ISOLATED STRONG TO LOCALLY DAMAGING
DOWNBURST WINDS. AN INSTANCE OR TWO OF SMALL HAIL MAY ALSO ACCOMPANY
THE MOST ROBUST CORES THAT DEVELOP ALONG THE SEA BREEZE. A LACK OF
GREATER EFFECTIVE SHEAR WILL LIMIT OVERALL STORM ORGANIZATION AND
LONGEVITY, THUS PRECLUDING A GREATER SEVERE RISK. GIVEN THIS, WATCH
ISSUANCE IS NOT ANTICIPATED.
