NWS Wilmington, NC wrote its last area forecast discussion before the first event at Aug 21, 8:06 PM EST, 26 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE WILMINGTON NC 906 PM EDT SUN AUG 21 2011 .SYNOPSIS... A COLD FRONT WILL ENTER THE WESTERN CAROLINAS TONIGHT AND TRACK ACROSS THE AREA LATE MONDAY INTO TUESDAY...ACCOMPANIED BY A CONTINUING CHANCE OF THUNDERSTORMS. HIGH PRESSURE WILL FOLLOW AND BUILD INTO THE CAROLINAS WEDNESDAY THROUGH THURSDAY. TROPICAL STORM IRENE COULD POTENTIALLY IMPACT THE SOUTHEAST STATES AS A HURRICANE AS NEXT WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... AS OF 900 PM SUNDAY...WE JUST SENT AN INTERMEDIATE UPDATE TO THE GRIDS AND TEXT FORECAST PRODUCTS TO ACCOUNT FOR RATHER WIDESPREAD CONVECTION DEVELOPING ACROSS THE EASTERN PIEDMONT/SANDHILLS REGION. THIS APPEARS TO BE JUST EAST OF THE PIEDMONT SURFACE TROUGH AND ALSO VERY NEAR THE AXIS OF THE UPPER LEVEL TROUGH THAT IS EXPECTED TO SWEEP EAST AND OFFSHORE VERY LATE TONIGHT. GIVEN ENOUGH ELEVATED INSTABILITY TO SUSTAIN THESE STORMS FOR THE NEXT SEVERAL HOURS WE HAVE INCREASED POPS INTO THE 60-70 PERCENT RANGE FOR MUCH OF THE SOUTH CAROLINA PEE DEE REGION NORTH OF FLORENCE...AND INTO ROBESON COUNTY NC. ONCE THE STORMS MOVE EAST INTO AREAS ALREADY WORKED OVER BY CONVECTION THEY MAY WANE IN INTENSITY...BUT LIKELY WILL NOT COMPLETELY FALL APART GIVEN THE UPPER LEVEL FORCING PERSISTING DOWN TO THE COAST. WE HAVE RAISED POPS TO 40-50 PERCENT AFTER MIDNIGHT FOR THE CAPE FEAR REGION. A CONVECTIVE OUTFLOW BOUNDARY PUSHED THROUGH THE CAPE FEAR REGION EARLIER...DROPPING TEMPS AND DEWPOINTS LOWER THAN EXPECTED. WE HAVE ADJUSTED THESE TRENDS IN THE FORECAST GRIDS...AND INDICATE THE ATMOSPHERE SLOWLY "RESETTING" BACK TO A SYNOPTIC SOUTHWEST WIND OVER THE NEXT 3-4 HOURS...WITH STEADY OR EVEN SLOWLY RISING TEMPERATURES EXPECTED. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... AS OF 3 PM SUNDAY...COLD FRONT WILL PASS THROUGH THE AREA ON MONDAY. BEST UPPER LIFT AND DEEPEST MOISTURE WILL BE SOUTH AND EAST OF THE AREA FOR THE MOST PART SO ONLY EXPECT ISOLATED TO SCATTERED STORMS WITH MAXIMUMS IN THE UPPER 80S TO LOWER 90S. AFTER STORMS WIND DOWN DURING THE LATE AFTERNOON OR EARLY EVENING...FAIR WEATHER IS EXPECTED FOR THE REMAINDER OF THE FORECAST PERIOD WITH COOLER TEMPERATURES. MIN TEMPERATURES BOTH NIGHTS WILL BE IN THE MID 60S TO AROUND 70. MAXIMUMS TUESDAY WILL BE IN THE MID 80S TO AROUND 90. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... AS OF 3 PM SUNDAY...MAIN STORY FOR THE PERIOD IS IRENE AND WHAT/IF ANY IMPACT IT WILL HAVE ON THE ILM AREA. WEAKNESS IN THE UPPER RIDGE WILL DEVELOP AS SERIES OF WEAK UPPER TROUGHS DIG OVER THE EASTERN US...ALLOWING THE STORM TO TURN NORTH. SOME OF THE MEDIUM RANGE GUIDANCE HAS CONTINUED SHIFTING THE TRACK OF IRENE EAST...BUT THERE HAS NOT BEEN A LOT OF RUN TO RUN CONSISTENCY SHOWN IN THE GUIDANCE AND CONFIDENCE THROUGH THE PERIOD IS LOW. IN FACT THE RANGE OF SOLUTIONS HAS THE STORM MAKING LANDFALL ANYWHERE FROM THE EASTERN GULF COAST TO MISSING THE EAST COAST AND RECURVING INTO THE WESTERN ATLANTIC. THE NEXT 24 TO 28 HOURS SHOULD PROVIDE A MUCH CLEARER PICTURE. AHEAD OF IRENES POTENTIAL ARRIVAL A DISSIPATING FRONT SOUTH OF THE AREA AT THE START OF THE PERIOD WILL RETURN NORTH WED AFTERNOON AS BERMUDA HIGH STARTS TO BUILD BACK IN. HAVE CARRIED CHC POP EACH DAY WITH HIGHEST LATE IN THE PERIOD...ASSUMING IRENE HAS SOME IMPACT ON THE REGION. 30S SHOULD COVER WED/THU WITH LOW LEVEL CONVERGENCE FROM ONSHORE FLOW BEING ENHANCED BY DIURNAL INSTABILITY. TEMPERATURES WILL BE NEAR TO ABOVE CLIMO...WITH LOWS POTENTIALLY WELL ABOVE CLIMO LATE IN THE PERIOD. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... AS OF 00Z...MODERATE CONFIDENCE OVERNIGHT DUE TO DISSIPATING CONVECTION TONIGHT AND STRATUS/FOG THREAT. VFR WILL REDEVELOP ON MONDAY BUT MORE TSTMS ARE POSSIBLE IN THE AFTN. PRIMARY CONCERN NOW IS ONGOING CONVECTION WHICH MAY IMPACT THE COASTAL TERMINALS DURING THE NEXT FEW HOURS. HAVE CARRIED TEMPO MVFR HERE TO ACCOUNT FOR THIS...IFR VSBYS ARE POSSIBLE BUT WILL HANDLE WITH AMD/S IF NECESSARY SINCE HEAVIEST RAINFALL MAY MISS THE TERMINALS. OTHER CONCERN TONIGHT IS STRATUS/FOG POTENTIAL. LBT RECEIVED QUITE A BIT OF RAIN...AND THE COASTAL TERMINALS MAY SEE SOME AS WELL. DEWPOINT DEPRESSIONS ARE RELATIVELY LOW ACROSS THE AREA...BUT A LLJ TONIGHT WILL BE TOO STRONG TO SUPPORT DENSE FOG. ATTM HAVE CARRIED SCT AT MVFR LEVEL AT THE COAST...WITH SCT IFR LEVEL CLOUDINESS INLAND. CONFIDENCE IS PRETTY LOW HOWEVER...AND HOPE TO SEE SOME STRATUS DEVELOPMENT BEFORE 06Z ISSUANCE. SOME MVFR VSBYS AT LBT APPEAR LIKELY...BUT OTRW MIXING SHOULD KEEP VSBYS UNRESTRICTED. WINDS WILL PERSIST FROM THE W/SW AT 5 TO 10 KTS OVERNIGHT...WITH SOME GUSTS AT THE COAST TO 15 KTS THROUGH THE FIRST FEW HOURS. COLD FRONT APPROACHING THE AREA WILL MOVE THROUGH DURING MONDAY TURNING WINDS TO THE W/NW DURING THE EVE...THE EXCEPTION BEING AT THE MYRTLES WHERE A SEA BREEZE WILL KEEP A SW FLOW THROUGH THE DAY. MORE SHOWERS AND TSTMS ARE POSSIBLE DURING THE AFTN...BUT FOR NOW HAVE CARRIED BKN CB AND WILL UPDATE WITH LATER ISSUANCES. EXTENDED OUTLOOK...SCATTERED AFTN SHRA/TSRA THROUGH THE EXTENDED. && .MARINE... NEAR TERM /THROUGH TONIGHT/... AS OF 730 PM SUNDAY...A COLD FRONT WILL MOVE INTO THE INTERIOR CAROLINAS AFTER MIDNIGHT TONIGHT. OUT AHEAD OF THE FEATURE THE PRESSURE GRADIENT WILL TIGHTEN AS THE BERMUDA HIGH TRIES TO CONTINUES TO POKE IN FROM THE EAST. ALL 12Z AND 18Z MODELS SHOW A RATHER HEALTHY LOW LEVEL JET TONIGHT...1000 FT WINDS OVER 20 KNOTS...PERSISTING ALMOST UNTIL DAYBREAK MONDAY. WITH SUCH A WARM OCEAN SURFACE THIS TIME OF YEAR WE EXPECT VERY GOOD VERTICAL MIXING TO TAP INTO THESE STRONGER WINDS ALOFT AND CONTINUE TO BRING 20-25 KT WINDS THROUGH MOST OF THE NIGHT. LATEST WIND OBSERVATIONS ALONG THE COAST SHOW THIS IS ALREADY THE CASE. SEAS ARE NOT QUITE AS HIGH AS EARLIER FORECASTS INDICATES. BUOYS ARE SHOWING 3 FT SEAS THROUGHOUT THE AREA...BUT WITH THE BULK OF THE ENERGY AT VERY SHORT PERIODS MAKING FOR A VERY BUMPY RIDE FOR SMALL CRAFT. AN EXERCISE CAUTION HEADLINE WILL REMAIN ON THE FORECAST THROUGH THE NIGHT. SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... AS OF 3 PM SUNDAY...SW WINDS MONDAY MORNING WILL SHIFT TO THE NW MONDAY NIGHT AND VEER TO THE EAST BY TUESDAY NIGHT. SPEEDS WILL RUN 15 KT OR LESS THROUGH MOST OF THE PERIOD EXCEPT MONDAY MORNING WHEN 20 KT WINDS ARE POSSIBLE. SEA HEIGHTS OF 3 TO 5 FEET MONDAY WILL DIMINISH TO 4 FT OR LESS MONDAY AFTERNOON AND REMAIN SO FOR THE REST OF THE PERIOD. LONG TERM /WEDNESDAY THROUGH FRIDAY/... AS OF 3 PM SUNDAY...SOUTHEAST FLOW AROUND 10 KT ACROSS THE WATERS WED INTO THU AS BERMUDA HIGH STARTS TO BUILD BACK IN FROM THE EAST. THU AND BEYOND BECOMES TROUBLESOME. ALL OF THE FORECAST PARAMETERS WILL DEPEND UPON THE TRACK...STRENGTH...AND SIZE OF IRENE. CURRENT FORECAST TRACK WOULD KEEP WINDS WITH AN EASTERLY COMPONENT OVER THE WATERS THROUGH THE END OF THE PERIOD WITH BUILDING SOUTHEAST SWELL. HOWEVER...THERE REMAINS PLENTY OF UNCERTAINTY AND THE 12Z GUIDANCE HAS NOT HELPED CLEAR UP THE PICTURE ANY. FOR NOW HAVE MADE LIMITED CHANGES TO LATER PERIODS...BUT SIGNIFICANT CHANGES COULD BE AFOOT. CURRENTLY HAVE SEAS CAPPED AT 6 FT LATE...BUT CANNOT RULE OUT 3 TIMES THIS VALUE IF IRENE PASSES MUCH CLOSER TO THE WATERS. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...NONE. NC...NONE. MARINE...NONE. && NEAR TERM...TRA SHORT TERM...31 LONG TERM...III AVIATION...JDW
