CONCERNING...SEVERE THUNDERSTORM WATCH 193...

VALID 211924Z - 212100Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 193
CONTINUES.

SUMMARY...THREAT FOR DAMAGING WINDS AND HAIL REMAINS ACROSS ERN NC.

DISCUSSION...RECENT SURFACE ANALYSIS PLACES THE FRONTAL BOUNDARY
FROM ASJ SSWWD TO JUST NW OF FLO. ENVIRONMENT AHEAD OF THIS BOUNDARY
WILL REMAIN UNSTABLE AS LOW-LEVEL MOISTURE CONTINUES TO ADVECT NWWD
INTO THE REGION. DEWPOINT AT THE DPL HAS INCREASED FROM 68 TO 71 DEG
F WITH A SIMILAR TREND NOTED AT ISO. MID-LEVEL LAPSE RATES WILL
REMAIN RELATIVELY POOR BUT THE QUALITY OF THE LOW-LEVEL MOISTURE
STILL SUPPORTS MLCAPE NEAR 1000 J PER KG. AS SUCH...TSTM ACTIVITY IS
EXPECTED TO CONTINUE AHEAD OF THE FRONTAL BOUNDARY WITH SOME
INCREASE IN COVERAGE AND INTENSITY POSSIBLE. PRIMARY SEVERE THREAT
IS DAMAGING DOWNBURST WINDS WITH SOME ISOLATED SEVERE HAIL ALSO
POSSIBLE.
