SATELLITE ANALYSIS AND TRENDS...MID-LVL VORT CAN BE SEEN IN WV IMAGERY
PRESSING NEWD ACROSS THE MID-ATLANTIC REGION PROVIDING LIFT AS THE ENERGY
SWINGS N OVER ERN NC. GOES SATL WINDS DEPICT AN DIFFLUENCE ALOFT E OF
THE VORT OVER NE NC/SE VA AS WELL AS AN UPPER LVL JET STRETCHED NEWD
FROM SE GA/E SC TO JUST OFF THE COAST OF DE/E MD WITH RIGHT ENT REGION
DYNAMICS FOCUSED OVER COASTAL SC.  A STNRY BNDRY IS ANALYZED ALONG THE SC
COAST TO SE/E NC PROVIDING A FOCUS FOR NR SFC AND LOW LVL CNVGC. LOW LVL
FLOW IS GNRLY SRLY TO SWRLY ALONG THE CAROLINA COASTS FEEDING MOISTURE
AND OFFSHORE INSTABILITY NWD/NEWD. 12Z RAOB PW ANALYSIS AND BLENDED TPW
PRODUCTS SHOW 2" OR GREATER PW`S THAT STRETCH NE ACROSS FL AND EXTEND
ALONG THE SE U.S. COAST PUSHING SLIGHTLY INLAND. GIVEN RELATIVELY LITTLE
SHEAR THROUGHOUT THE LAYER PER MHX 12Z RAOB AND DEEP LAYERED POOL OF
MOISTURE SHOWN BY EXPERIMENTAL CIRA LAYERED PW PRODUCT...RAINFALL RATES
SHOULD CONTINUE TO BE QUITE EFFICIENT. LIMITING FACTOR WILL BE THAT NEEDED
INSTABILITY IS ISOLATED TO COASTAL AND OFFSHORE REGIONS CURRENTLY THOUGH
STRONG LOW LVL INFLOW SHOULD BE ABLE TO DRAW SOME OF THIS MORE UNSTABLE
AIR INLAND ACROSS E NC.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1345-1645Z...MEDIUM-HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...A WEAKER SECONDARY IMPULSE IS SEEN IN WV IMAGERY
LIFTING NEWD ACROSS COASTAL GA/SE SC  WHICH APPEARS TO BE PART OF THE
REASON FOR RENEWED CLOUD TOP COOLING CURRENTLY OCCURRING OFFSHORE
SC..IN ADDITION TO PREVIOUSLY MENTIONED JET DYNAMICS. BELIEVE MAIN
THREAT FOR MOD-HVY RAINFALL SHOULD SHIFT NWD WITH THIS S/WV IMPULSE
THROUGH THE MORNING HRS AND CANNOT RULE OUT THE STRENGTHENING OFFSHORE
CNVCTN REACHING THE ERN SC COAST AGAIN OVER THE NEXT  FEW HRS. ADDTL
CLOUD TOP COOLING AND OVERSHOOTING TOPS SEEN IN VIS ARE EVIDENT SE OF
ILM/MRH IN NC AND THESE SHOULD EVENTUALLY WRAP NWD ACROSS SERN PARTS
OF NC. HEAVIEST RAINS ARE EXPECTED NR THE COAST IN ERN SC BUT SHOULD BE
ABLE TO WORK FURTHER INLAND ACROSS E NC GIVEN STRONG INFLOW WHICH WILL
BE INTERSECTING/OVERRUNNING THE INLAND STNRY FRONT.
