SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS POPPING THIS AFTERNOON ALONG A REMNANT WARM FRONTAL BOUNDARY AND WEAK UPPER SHORTWAVE ENERGY. CU FIELD WAS RATHER LIMITED ACROSS SOUTHEAST GA THIS MORNING COMPARED TO SC...AND THIS HAS BEEN THE RULE FOR CONVECTIVE COVERAGE AS WELL. ACTIVITY SHOULD WANE WITH THE LOSS OF DAYTIME HEATING...THUS HAVE TAPERED POPS BACK THROUGH THE EVE FROM THE COAST INLAND. LACK OF FORCING OVERNIGHT SHOULD KEEP SHOWERS OFFSHORE...SO HAVE REMOVED OVERNIGHT POPS OVER LAND. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...

MORE POTENT SHORTWAVE WILL DROP SE THROUGH THE LONG WAVE TROUGH DURING THE AFTERNOON...WITH STEEPER MID-LEVEL LAPSE RATES. NAM SHOWED VALUES ABOVE 6 DEG/KM ALONG THE COAST...WITH CAPE ABOVE 1800 J/KG.

HIGH TEMPS AGAIN CREEPING INTO THE LOWER 90S FAR INLAND WITH MID TO UPPER 80S CLOSE TO THE COAST SEEM REASONABLE. && .LONG TERM /SATURDAY THROUGH THURSDAY/... LEE-SIDE TROFG IS PROGGED FOR SAT-MON AHEAD OF A CDFNT. THE TROF AND SEA BREEZE WL BE THE PRIMARY FOCI FOR SHOWERS AND TSTMS THROUGH THIS PERIOD. THE NAM-WRF SUGGESTS A LARGE CLUSTER OF TSTMS MAY ORGANIZE INTO AN MCS SAT AFTN ACROSS WRN NC AND THE NRN MIDLANDS. WITH A NW STEERING FLOW ALOFT THE TAIL END OF THIS MCS MAY MOVE THROUGH OR BRUSH THE NRN PORTIONS OF THE FCST AREA SAT EVNG AS A SHORTWAVE PASSES OFF THE N. WL MAINTAIN CHANCE POPS FOR SAT-MON. STRONG TO SVR TSTMS WL BE A POSSIBILITY EACH DAY WITH DAMAGING WINDS...LCLLY HEAVY RAINS AND CLOUD TO GROUND LIGHTNING BEING THE PRIMARY HAZARDS.

WINDS HAVE GENERALLY SHIFTED SE TODAY EXCEPT FOR FAR NORTHERN PORTIONS WHERE A MORE E-NE TRAJECTORY REMAINS. EXPECT WINDS TO BECOME SW AND W TONIGHT BEFORE SHIFTING BACK S ON FRI DUE TO ATLANTIC HIGH PRESSURE BUILDING WEST AND LEE TROUGHING TO THE WEST. WEAK DIURNAL SURGES WILL CONTINUE...ALTHOUGH WINDS AND SEAS WELL BELOW HEADLINE CRITERIA ARE EXPECTED. A SLY FLOW WL PERSIST ACROSS THE MARINE AREA THROUGH MON WITH ATLC HIGH PRES REMAINING WELL OFFSHORE. A CDFNT WL APRCH THE WTRS TUE AND LIKELY BECOME STNRY TUE NGT.
