.
SATELLITE ANALYSIS AND TRENDS...UPPER LOW IS SLOWLY ROTATING OVER THE
APPALACHIANS STAYING NEARLY STNRY THOUGH AND IS SEEN BECOMING MORE
ELONGATED IN RECENT WV IMAGES. GOES STLT WINDS INDICATE MOD TO STRONG
UPPER LVL DVG OVER NE NC/E VA/CENTRAL MD DUE TO THE POSITIONING OF THE
UPPER CIRCULATION. UNTIL NEXT SYSTEM COMING ALONG THROUGH THE CENTRAL
US ARRIVES TO KICK THE UPPER LOW OUT OF THE APPALACHIANS..EXPECT
BANDED STORM STRUCTURES TO CONTINUE TO BE A DOMINANT FEATURE OVER
THE MID-ATLANTIC REGION. TRAINING/SLOW MOVING WARM TOP CELLS OVER N
NC INTO SRN VA HAVE PROVEN TO BE VERY PROBLEMATIC PRODUCING SEVERAL
INCHES OF RAINFALL IN A SHORT PERIOD OF TIME. TRAINING CELLS ARE
ANCHORED OVER N EDGECOMBE/E HALIFAX COUNTIES IN NC AND STRETCH NWD
INTO E CENTRAL VA THOUGH ANOTHER BAND ROTATING ENE APPROACHING THE
LINE OF CELLS IS ALSO ENHANCING. MERGERS HAVE ALREADY STARTED TO
OCCUR PER VIS IMAGERY INVOF BRUNSWICK/MECKLENBURG/WARREN COUNTIES NR
THE NC/VA BORDER AND CAN EXPECT ADDTL CELLS TO CONTINUE TO FORM S OF
THESE STORMS TWDS NASH/WILSON/EDGECOMBE COUNTIES. MANUAL ESTIMATES
OF CURRENT RAINFALL AMOUNTS ARE FROM 1745Z-1945Z ARE BETWEEN 2-2.8"
FROM HALIFAX COUNTY/NC TO PRINCE GEOGES COUNTY/VA WITH UP TO 3.3" OVER
NORTHAMPTON/SOUTHAMPTON/GREENSVILLE COUNTIES DUE TO A MERGER.
.
ADDTL CELLS OVER CENTRAL NC ARE ALSO SLOW MOVING AND HAVE RECENTLY SHOWN
TRENDS OF BUILDING TO THE NNW INTO SW VA CURVING BACK TWDS SE WV. GOES
SOUNDER/GPS VALUES INDICATE LI'S OF -5 TO -7 TO THE N/NNW SO SHOULD SEE
SOME NWD GROWTH AS WELL AS THE POSSIBILITY OF CELL GROWTH SSEWD FROM THIS
COMPLEX. AT LEAST CELLS ARE STARTING TO MOVE THOUGH BUT WILL STILL NEED TO
BE WATCHED CLOSELY. SEE WEB ADDRESS IN ABOUT 10 MIN FOR GRAPHIC ANALYSIS.
