AREAS AFFECTED...PORTIONS OF THE MID-ATLANTIC
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 101910Z - 102145Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...ISOLATED LOW-TOPPED CONVECTION MAY PRODUCE LOCALLY STRONG
WIND GUSTS, WITH AN ISOLATED DAMAGING WIND GUST OR TWO POSSIBLE.
DISCUSSION...LATEST REGIONAL RADAR IMAGERY DEPICTS ISOLATED,
LOW-TOPPED CONVECTION DEVELOPING ALONG PORTIONS OF THE
APPALACHIANS/BLUE RIDGE. WHILE LOW-LEVEL MOISTURE WILL LIMITED AHEAD
OF AN APPROACHING COLD FRONT (SURFACE DEWPOINTS IN THE 40S TO
LOW-50S F), LATEST MESOANALYSIS AND RECENT ACARS PROFILES FROM
DCA/BWI DEPICT WEAK BUOYANCY (100-300+ J/KG MLCAPE), STEEP LOW-LEVEL
LAPSE RATES (8.5-9.0 C/KM), AND DEEP, WELL-MIXED BOUNDARY LAYERS
ACROSS THE REGION. THIS WILL PROMOTE SOME POTENTIAL FOR ISOLATED
GUSTY WINDS, AND PERHAPS A DAMAGING WIND GUST OR TWO, WITH ANY
STRONGER DOWNDRAFTS AS CONVECTION SPREADS EASTWARD ACROSS THE AREA.
WITH THE SEVERE RISK FORECAST TO REMAIN LIMITED IN COVERAGE AND
