CONCERNING...SEVERE THUNDERSTORM WATCH 792...

VALID 021830Z - 022000Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 792
CONTINUES.

AND...A SMALL EXPANSION OF THE WW MAY BE NEEDED EWD INTO THE COASTAL
PLAINS OF ERN NC/NE SC.

DEEP WNWLY UNIDIRECTIONAL FLOW REGIME HAS BEEN FAVORABLE FOR TSTMS
TO DEVELOP ALONG BOTH THE CREST OF THE HIGHER APLCN TERRAIN AND THE
PRE-FRONTAL TROUGH ACROSS SW VA/NW NC THIS AFTN.  RECENTLY... OTHER
TSTMS HAVE INITIATED ALONG A WEAK LEE-TROUGH OVER THE NC SANDHILLS.
VSBL SATL SHOWS ADDITIONAL TCU STREETS SPROUTING OVER NRN SC.

KINEMATIC SET-UP WILL BE FAVORABLE FOR DIURNALLY ENHANCED TSTMS TO
FORM UPSTREAM OVER THE MOUNTAINS AND MOVE ESE INTO THE LWR
ELEVATIONS OF CNTRL NC THROUGH LATE AFTN.  NUMBER OF STORMS HAS
INCREASED SINCE 17Z...AND STRENGTHENING COLD POOLS WILL ELONGATE
ESEWD...ALIGNING WITH THE MEAN WIND WITH SUBSEQUENT SMALL SCALE
BOWS.  GIVEN STEEP LOW-LVL LAPSE RATES IN PLACE...THESE BOWS WILL BE
CAPABLE OF DMGG WIND GUSTS.

MEANWHILE...TSTMS DEVELOPING FARTHER SE COULD ALSO BECOME
SVR...ESPECIALLY AS THE SEABREEZE MOVES NWWD AND COMBINES WITH
OUTFLOW BOUNDARIES.  THESE STORMS WILL BE EMBEDDED IN A
COMPARATIVELY SIMILAR WIND REGIME AS THE STORMS FARTHER NW...THUS
EXPECT AT LEAST ISOLD DMGG WIND GUSTS/HAIL TO RESULT WITH STORM
MOVEMENT INTO NERN SC/ERN NC BY LATE THIS AFTN.
