AREA FORECAST DISCUSSION...CORRECTED MEDIUM RANGE PORTION NATIONAL WEATHER SERVICE CHARLESTON SC 200 PM EDT MON APR 7 2003 CONVECTIVE...COASTAL SOUTH CAROLINA REMAINS IN JUICY AIR MASS THIS AFTERNOON...WITH NEARLY MOIST ADIABATIC LAPSE RATES PREVENTING THUNDERSTORMS FROM ORGANIZING MUCH SO FAR TODAY. THE BROAD LINE OF STORMS...HOWEVER...WHICH CURRENTLY EXTEND FROM KCRE-KOGB-KAGS-KWRB ARE SLOWLY PRESSING SOUTHEASTWARD TOWARD THE COASTAL PLAIN. THESE STORMS ARE BECOMING MORE LINEARLY ORGANIZED ACROSS CENTRAL GEORGIA. RUC40 FORECASTS THE LOW-LEVEL FORCING TO WEAKEN THIS AFTERNOON...BUT COLLIDING BOUNDARIES AND SEA-BREEZE CONVERGENCE MAY YET ALLOW FOR SOME ORGANIZATION THROUGH THIS EVENING. OVERNIGHT THE UPPER SUPPORT STRENGTHENS...AND WITH UNSTABLE AIR MASS IN PLACE...THE POTENTIAL FOR STRONG THUNDERSTORMS EXISTS ONCE AGAIN INTO TUESDAY. HYDRO...ANOTHER CONCERN IS FLASH FLOODING TONIGHT...BUT MOST LOCATIONS HAVE SEEN LITTLE OR NO RAINFALL THUS FAR. AT THIS TIME WE WILL CONTINUE TO MONITOR THE SITUATION...BUT WE ARENT PLANNING ON ISSUING ANY HEADLINES WITH THE AFTERNOON PACKAGE. PUBLIC... DAYS 1 TO 3...AS COLD UPPER VORTEX SLOWLY DIVES TOWARD THE SOUTHEASTERN U.S...A SERIES OF SHORTWAVES WILL TRACK FROM THE EASTERN GULF OF MEXICO INTO THE FORECAST AREA TONIGHT THROUGH THURSDAY. COLD AIR DAM HOLDS IN PLACE ALONG THE APPALACHIANS THROUGH WEDNESDAY...WITH SOUTHERLY WINDS OVER OUR FORECAST AREA. GFS SOLUTION RACES A WEAK SURFACE LOW THROUGH THE REGION TUESDAY AFTERNOON AND SWIFTLY DRAGS THE BOUNDARY THROUGH TUESDAY EVENING. WE PREFER THE MORE DELIBERATE ETA SOLUTION...WHICH HOLDS OUR REGION IN THE WARM SECTOR THROUGH WEDNESDAY AS THE SURFACE WAVE CLOSES OFF MORE FULLY TUESDAY NIGHT ALONG THE SOUTH CAROLINA COAST. THIS WILL LEAVE OPEN THE POTENTIAL FOR THUNDERSTORMS THROUGH WEDNESDAY AFTERNOON. THEN THE BOUNDARY SHIFTS OFFSHORE AS THE SURFACE CYCLONE ASSOCIATED WITH THE UPPER LOW TRACKS ACROSS THE FLORIDA PENINSULA AND INTO OUR COASTAL WATERS. SYSTEM SHOULD BE WELL OCCLUDED BY THIS TIME...AND THERE IS LIKELY TO BE SIGNIFICANTLY DRIER AIR WRAPPING NORTHWARD TOWARD OUR REGION ON THURSDAY. HAVE THUS MAINTAINED CHANCE POPS FOR THURSDAY BASED ON UNCERTAINTY OF THE SYSTEMS DEVELOPMENT. DAYS 4 TO 7...AS PER HPC MEDIUM RANGE DISCUSSION...WILL GENERALLY FOLLOW GFS SOLUTION FOR THE FRIDAY-MONDAY PERIODS. BIGGEST CHANGE FROM OPERATIONAL GFS WILL BE TO HASTEN THE CLEARING THURSDAY NIGHT INTO FRIDAY. DRY FROM THE WEEKEND INTO EARLY NEXT WEEK AS MODELS ANCHOR A LARGE UPPER RIDGE OVER THE SOUTHEASTERN STATES. TEMPERATURES OUGHT TO WARM TO NEAR NORMAL READINGS BY SATURDAY. MARINE...ALTHOUGH SHORT TERM AGREEMENT BETWEEN ETA AND GFS WITH INLAND WEDGING AND LIFTING INITIAL LOW OFF THE NC COAST...GFS IS MUCH QUICKER LIFTING NEXT LOW THROUGH GA AND THE CAROLINAS ON TUE. ETA IS DIGGING MORE AND HANGS SFC REFLECTION WELL BEHIND...WHICH ATTIM SEEMS TO HAVE BETTER TIMING. MARINE ZONES WILL LEAN MORE TOWARD THE SLOWER SOLUTION. STILL AN UNSETTLED SCENARIO ALONG THE SE COAST OVER THE NEXT FEW DAYS WITH A GENERALLY S FLOW FOR SRN WATERS THROUGH TOMORROW AND MUCH OF WED...AN EAST COMPONENT POSSIBLE ON TUE NRN WATERS. WED WILL START OFF INIT S/SW BUT LINGERING BOUNDARY WILL MAKE A MESS OF WIND DIR NEAR SHORE DURING THE DAY. BY THU UPR LOW IS SWINGING TOWARDS THE COAST AND BEGINS TO FINALLY CLEAR THIS REGIME TO THE E AND NE. SHORT TERM SCA HEADLINES WILL REMAIN FOR NRN WATERS MAINLY FOR SEAS.
