SHEAR AXIS CONTINUES TO PRESS SOUTHEAST THIS AFTERNOON WITH MOST ROBUST DEEP CONVECTION ALONG THE LEADING EDGE OF THIS FEATURE AND GETTING READY TO EXIT FLOOD WATCH AREA. WEAK INSTABILITY AT BEST IS IN IT/S WAKE AND DOUBTFUL MORE THAN SCATTERED TSTMS WILL REDEVELOP ACROSS THE WATCH AREA...SO WILL PLAN ON LETTING FLOOD WATCH EXPIRE ON SCHEDULE. PREFER THE NAM HANDLING OF SYNOPTIC FEATURES THROUGH SATURDAY...LINGERING SHEAR AXIS ACRS SE FRINGES OF THE CWFA AND AFTER THIS EVENING...KEEPING 85H FLOW NORTHEAST VERSUS UPSLOPE GFS SOLUTION...WHICH LOOKS TO HAVE FEEDBACK PROBLEMS ANYWAY. HPC PCPN PROGS SEEM TO AGREE WITH THIS AS WELL WITH HIGHER QPF ACRS THE CENTRAL AND EASTERN CAROLINAS THROUGH 00Z SUNDAY. && .LONG TERM (SATURDAY NIGHT THROUGH FRIDAY)... BOTH THE ETA AND GFS INDICATE A BROAD 500HPA TROUGH OVER THE EAST AT THE END OF THE WEEKEND WITH THE AXIS SLOWLY MOVING TOWARD THE EASTERN SEABOARD. BOTH INDICATE A VERY MOIST ATMOSPHERE TO THE EAST OF THIS AXIS WITH PRECIPITABLE WATER VALUES OVER TWO INCHES. THE GFS INDICATES A WEDGE-LIKE SIGNATURE IN THE INSTABILITY INDICES FOR SUNDAY AFTERNOON AND WITH A HIGH OVER THE NORTHEAST...THIS MAY SEEM REASONABLE. WITH THIS HIGH OVER THE NORTHEAST AND WEAK LOW PRESSURE TO THE SOUTH...AN EASTERLY FLOW WILL PREVAIL AT THE END OF THE WEEKEND AND START OF THE WEEK. THE ETA PROGRESSES THE UPPER TROUGH AXIS FASTER TO THE EAST WITH THE OFFSHORE HIGH WEAKENING. AS HAS BEEN COMMON...THE GFS HAS BEEN MORE DEPENDABLE SO WE EXPECT THIS PROGRESSION TO THE BE SLOWER RATHER THAN FASTER. THE WEAK SURFACE FRONT NEAR THE COAST WILL GRADUALLY DISSOLVE IN THE FIRST HALF OF THE WEEK. WEAK HIGH PRESSURE OVER THE MID ATLANTIC REGION WILL EXERT MORE OF AN INFLUENCE INTO MID WEEK AS POPS DECREASE OVERALL. WE HAVE MAINTAINED SOME DIURNAL POPS WITH EITHER SLIGHT OR LOW CHANCE POPS MAINLY IN THE SOUTH BUT MORE PRONOUNCED WITH THE HIGHER TERRAIN IN THE MID WEEK. WE WILL HAVE TO WATCH THE PROGRESS OF THE STRONG TROPICAL WAVE LOCATED NEAR AND TO THE EAST OF THE VIRGIN ISLANDS. THIS IS EXPECTED TO MOVE TO NEAR THE BAHAMAS BY MID WEEK AND BY LATE WEEK MAY BRING TROPICAL RAIN TO THE SOUTHEAST AGAIN. && .AVIATION... IMMEDIATE SHORT TERM CONCERN LIES WITH THE KCLT TAF AS A BROKEN LINE OF TSTMS WILL LIKELY REDUCE CIGS/VSBYS INTO IFR RANGE FOR A FEW HOURS THIS AFTERNOON. ELSEWHERE...AS SHEAR AXIS DRIFTS INTO THE PIEDMONT...A LULL IN SHOWERS/TSTMS EXPECTED FOR THE AFTERNOON AS CLDS/PCPN HAS SIGNIFICANTLY RETARDED DESTABILIZATION. LIFT LINGERS INTO THE EVENING...BUT DEBATABLE HOW MUCH CVRG OF SHOWERS WE WILL SEE AS THE ATMOSPHERE STABILIZES. HIGH THREAT FOR AT LEAST MVFR CIGS/VSBYS AT ALL SITES AS THE NIGHT WEARS ON AND HAVE CONTINUED THREAT FOR IFR CONDITIONS AS WELL FOR AROUND DAYBREAK. && .GSP WATCHES/WARNINGS/ADVISORIES...
