EVENT...CONTINUED MOD/HVY RAINS WITH BAND AND HVY RAINS FROM CONVECTIVE
CELLS
.
SATELLITE ANALYSIS AND TRENDS...MOD/HVY RAIN CONTINUES TO FALL ACROSS
SE VA AND NE NC AND ARE EXPECTED TO CONTINUE OVER THE NEXT SEVERAL HRS.
IR AND VIS IMAGERY SHOWS A BAND ORIENTED SE-WNW..EXTENDING FROM DARE
COUNTY (NC) NWWD TO SURRY COUNTY (VA)..ROTATING COUNTERCLOCKWISE AROUND
THE UPPER LVL LOW CENTERED NEAR 35N/78W PER WV ANALYSIS.  HEAVIEST RAIN
RATES SHOULD BE ALONG THE NORTHERN FRINGE OF THE BAND WHERE VIS IMAGERY
HAS A MORE TEXTURED CLOUD PATTERN LOOK TO IT.  CLOUD TOP TEMPS FROM THIS
BAND HAS WARMED SLIGHTLY OVER THE PAST HR TO AROUND -39C..SO RAIN RATES
MAY LET UP A BIT BUT CONCERN IS FOR BAND TO POTENTIALLY INTENSIFY AGAIN
WITH ANOTHER LOBE OF VORTICITY SEEN ROTATING AROUND THE UPPER LOW..JUST TO
THE WEST OF THE LOWS CENTER.  THIS LOBE CAPABLE OF PROVIDING ADDITIONAL
MID-UPPER LVL LIFT ALREADY APPEARS TO BE HELPING TO PROVIDING ENHANCED
UVVS OVER CENTRAL NC WHERE CONVECTIVE CELLS HAVE DEVELOPED.

ADDITIONALLY..CONVECTION HAS BROKEN OUT ACROSS S/CENTRAL EASTERN NC INVOF
JONES..CRAVEN..BEAUFORT..PITT COUNTIES PRODUCING HVY RAINS BUT AT THE
MOMENT CELLS HAVE BEEN PROGRESSIVELY MOVING NWD.  WITHIN THIS CLUSTER
OF TSTMS CELL MERGERS HAVE BEEN NOTED FROM VIS IMAGERY AS OVERSHOOTING
TOPS HAVE COLLIDED WITH EACH OTHER OVER THE PAST ½ HR AND ARE LIKELY TO
CONTINUE TO OCCUR WHICH WILL BRIEFLY PROVIDE INCREASE RAIN RATES OVER
LOCALIZED AREAS.  RAINFALL RATES MAY BE REACHING 1.0-1.25" FROM THESE
CELLS PARTICULARLY INVOF CELL MERGERS.  WITH THE VORTICITY LOBE EXPECTED
TO ROUND THE BASE OF THE CENTER OF THE UPPER LOW THIS AFTERNOON AND WITH
MODEST SFC MOISTURE CONVERGENCE PER 19Z SFC ANALYSIS AND PW VALUES AROUND
1.0" FROM GOES SOUNDER DATA REMAIN OVER EASTERN NC..ADDITIONAL CONVECTION
MAY OCCUR OVER THESE SAME FOUR COUNTIES MENTIONED ABOVE RESULTING IN
MORE HVY RAINFALL THIS AFTERNOON AND INTO THE EVENING HOURS.
