NWS Wilmington, NC wrote its last area forecast discussion before the first event at Aug 17, 9:59 AM EST, 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON NC 1059 AM EDT SAT AUG 17 2013 .SYNOPSIS... COOL AND WET WEATHER WILL CONTINUE FOR MUCH OF THE WEEKEND AS DEEP TROPICAL MOISTURE STREAMS NORTHWARD ALONG A FRONTAL BOUNDARY. CONDITIONS MORE TYPICAL OF LATE AUGUST WILL DEVELOP NEXT WEEK AS THE FRONT SLOWLY DISSIPATES AND BERMUDA HIGH PRESSURE BECOMES THE MAIN INFLUENCE ON OUR WEATHER. && .NEAR TERM /THROUGH TONIGHT/... AS OF 10 AM SATURDAY...A FRONT REMAINS POSITIONED OFFSHORE. UNSEASONABLY COOL TEMPERATURES ARE EXPECTED AGAIN TODAY AS CLOUDS BLANKET THE FORECAST AREA FOR MOST OF THE DAY. HIGHS ARE ONLY EXPECTED TO REACH THE MID AND UPPER 70S. A LARGE AREA OF SHOWERS AND A FEW THUNDERSTORMS...COINCIDENT WITH A WAVE OF LOW PRESSURE MOVING UP A STALLED OFFSHORE FRONT...WAS PROGRESSING TO THE NORTHEAST LATE THIS MORNING. THE BRUNT OF THIS CONVECTION WILL MOVE ACROSS THE WATERS AND OFFSHORE THROUGH THE AFTERNOON. HOWEVER...THE WESTERN FRINGES OF THIS ACTIVITY WILL SKIRT THE COAST AS THE AREA EXPANDS...ESPECIALLY THE CAPE FEAR AREA. THUS...FOR THE NEXT SEVERAL HOURS...EXPECT THE COVERAGE OF SHOWERS TO INCREASE...ESPECIALLY ALONG AND EAST OF A LINE FROM CRE TO CPC AND EYF. A THUNDERSTORM CAN NOT BE RULED OUT ALTHOUGH MOST OF THE THUNDERSTORM ACTIVITY IS EXPECTED TO REMAIN ON THE WARM SIDE OF THE OFFSHORE FRONT. DEVELOPING SUBSIDENCE DOWNSTREAM OF THIS ACTIVITY IS EXPECTED TO HELP SQUELCH CONVECTION WEST OF THE AFOREMENTIONED LINE FOR THE NEXT SEVERAL HOURS. WILL SHOW POPS EVENTUALLY TRENDING HIGHER IN THESE AREAS DURING THE AFTERNOON. A SERIES OF WAVES MOVING ALONG THE FRONT AND INDUCED BY UPPER LEVEL DISTURBANCES RIDING UP THE LEADING EDGE OF AN UNSEASONABLY DEEP H/5 EAST COAST TROUGH WILL KEEP THE WEATHER UNSETTLED. OVERRUNNING PATTERN IN PLACE FOR THE PAST FEW DAYS STILL VERY EVIDENT...WITH A DEEP TROPICALLY-SOURCED AIRMASS OVERRIDING A RELATIVELY COOL AND MOIST EASTERLY FLOW CLOSER TO THE SURFACE. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... AS OF 315 AM SATURDAY...THE FA WILL LIE IN BETWEEN THE WESTERN ATLANTIC RIDGE AND THE CUTOFF LOW ACROSS THE CENTRAL MISSISSIPPI VALLEY. AMPLE SUPPLY OF MOISTURE ACROSS THE FA...AS FEEDS FROM BOTH THE ATLANTIC AT THE LOW LEVELS...AND THE GULF OF MEXICO MID AND UPPER LEVELS...ADVECT ACROSS THE FA. WEAK AREA OF LOW PRESSURE IS PROGGED BY THE MODELS TO TRAVEL ALONG A COASTAL TROF/FRONT ORIENTED NE-SW OVER THE ATLANTIC WATERS..AND PARALLEL TO THE CAROLINA COASTS. THE LOW DEPARTS TO THE NE OFF THE DELMARVA COAST BY DAYBREAK MONDAY. UPSTAIRS...THE CUTOFF LOW ACROSS THE CENTRAL PART OF THE U.S. OPENS UP INTO A PROGRESSIVE POSITIVELY TILTED S/W TROF WHICH REACHES THE NE AND MID-ATLANTIC STATES LATE MONDAY NIGHT. AT THE SFC ON SUNDAY...WEAK HIGH PRESSURE IS PROGGED TO AFFECT THE FA. ONE WOULD THINK THAT WE ARE SAFE FROM ANY PCPN OCCURRENCE ON MONDAY. HOWEVER...MOISTURE REMAINS IN ABUNDANCE ACROSS THE FA. WEAK 5H VORTICIES ARE PROGGED TO PUSH ACROSS THE FA MONDAY INTO MONDAY NIGHT. IN ADDITION...ANY AMOUNT OF INSOLATION EITHER DAY WILL RESULT IN FURTHER DESTABILIZATION OF THE ATM LOCALLY. AS A RESULT OF ALL THIS SAID...POPS SUNDAY AND MONDAY WILL BE IN THE MODERATE TO HIGH CHANCE CATEGORY. THIS IS IN GOOD AGREEMENT WITH BOTH THE NAM AND GFS MOS GUIDANCE. FOR MAX TEMPS...LEANED TOWARD THE SLIGHTLY HIGHER NAM MOS GUIDANCE WHEN COMPARED TO THE GFS. AS FOR LOWS...BOTH MODEL MOS GUIDANCE QUITE SIMILAR AND SEE NO REASON TO DETOUR FROM THEIR OUTPUT. THE LATEST HPC 48 HR GUIDANCE FOR RAINFALL ACROSS THE ILM CWA...INDICATES BETWEEN 1 TO 2 INCHES POSSIBLE. AT THIS POINT A FLOOD WATCH IS NOT RECOMMENDED...BUT AS GROUNDS FURTHER BECOME SATURATED...WILL HAVE TO RE-VISIT THIS ISSUE ONCE AGAIN IF HPC FUTURE PCPN FORECASTS COME IN AT MODEST TO HIGH LEVELS. && .LONG TERM /TUESDAY THROUGH FRIDAY/... AS OF 315 AM SATURDAY...THE OPENED UP UPPER TROF WILL JUST BECOME A MEMORY AS ITS IS ABSORBED WITHIN THE MAIN BELT OF THE UPPER WESTERLIES. WITH NW FLOW ALOFT...THIN BAND OF MOISTURE...HAVING BEEN STRETCHED APART WILL DROP SE-WARD...AND CROSS THE FA DURING WEDNESDAY. BEWARE THE NW FLOW...AN ADAGE THAT HAS COME TO LIGHT WHEN DEALING WITH CONVECTION DROPPING SE-WARD FROM UPSTREAM. A MCC OR MCS USUALLY IS THE CULPRIT WITH THIS TYPE MID/UPPER LEVEL FLOW. CHANCE POPS WILL CONTINUE FOR TUE AND WED. BY THU AND FRI...MODELS DIVERGE FROM ONE ANOTHER WITH THEIR OWN RESPECTIVE SOLUTIONS DEALING WITH THE RE-TURN OF MOISTURE AND INCREASING POPS. REMAINED RATHER SOMEWHAT LOW-KEY WITH POPS THIS LATE IN THE TIME PERIOD DUE TO THE UNCERTAINTY. && .AVIATION /12Z SATURDAY THROUGH WEDNESDAY/... AS OF 12Z...CEILINGS THIS MORNING WILL BE PREDOMINATELY IFR... HOWEVER THEY WILL PROBABLY BOUNCE IN AND OUT OF MVFR...PARTICULARLY AFTER 15Z. THE HRRR MODEL HAS A SURFACE LOW OFFSHORE THAT WILL MOVE SLOWLY NORTHEAST THROUGH THE DAY. THE MODEL IS NOT ALL THAT ENTHUSED WITH THE PRECIP TODAY...WITH MAINLY ONLY SCATTERED ACTIVITY. BASED ON THE CURRENT RADAR...THIS SCENARIO SEEMS REASONABLE. VISIBILITIES IN THE RAIN COULD LOWER TO IFR...BUT PREDOMINATELY MVFR. WINDS ARE A BIT MORE NORTHERLY THAN PREVIOUSLY THOUGHT...PARTICULARLY INLAND ON THE BACK SIDE OF THE SURFACE LOW. LOOK FOR THE WINDS TO SHIFT MORE NORTHWESTERLY AS THE LOW EXITS THE REGION THIS AFTERNOON. EXTENDED OUTLOOK...ISOLATED TO SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS THROUGH THE EXTENDED PERIOD. && .MARINE... NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... AS OF 10 AM SATURDAY...A FRONT REMAINS STALLED OFFSHORE LATE THIS MORNING. THIS FRONT IS EXPECTED TO MOVE BACK ACROSS THE WATERS AS WAVES OF LOW PRESSURE MOVE UP ALONG THE BOUNDARY. THUS EASTERLY WINDS ARE EXPECTED TO VEER TO A MORE SOUTHERLY DIRECTION THROUGH THE AFTERNOON AND THEN TO SOUTHWEST FOR A TIME. WINDS WILL VEER TO W OR NW TONIGHT AS A WAVE OF LOW PRESSURE CLOSES OFF AND MOVES TO OUR N. WIND SPEEDS WILL GENERALLY BE AROUND 10 KT OR LESS. SEAS OF 2 TO 3 FT WILL PERSIST. NUMEROUS TO WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS WILL RESULT IN POOR VISIBILITIES INTO TONIGHT. SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... AS OF 330 AM SATURDAY...THE WESTERN ATLANTIC UPPER RIDGE AXIS IS PROGGED TO EXTEND FURTHER WESTWARD...PUSHING THE MAIN MOISTURE PLUME ORIENTED NE-SW FURTHER INLAND. THIS WILL POSSIBLY PROVIDE SOME DRYING CONDITIONS FOR MARINERS TRAVERSING THE LOCAL AND OFFSHORE WATERS LATER SUNDAY INTO MONDAY. AN EXITING SFC LOW TO THE NE ALONG A COASTAL FRONT WILL HIGHLIGHT SUNDAY...FOLLOWED BY WEAK HIGH PRESSURE ACROSS THE AREA FOR MONDAY. THE SFC PRESSURE GRADIENT WILL TIGHTEST AT THE BEGINNING OF THE SHORT TERM RELATIVELY SPEAKING...THEN RELAX THROUGH MONDAY AS HIGH PRESSURE BECOMES DOMINATE WX FEATURE. FOR SIGNIFICANT SEAS...AN ESE GROUND SWELL AT 9 SECOND PERIODS TO APPROACH THE LOCAL WATERS SUNDAY...AND AFFECT THE WATERS LATE SUNDAY NIGHT THROUGH MONDAY. EXPECT WIND DRIVEN WAVES AT 4 TO 6 SECOND PERIODS WILL DOMINATE AT THE START...BUT EVEN OUT ONCE THE SWELL TRAVERSES THE WATERS. 2 TO 3 FT...LIKELY HIGHER ONCE THE SWELL PUSHES ACROSS THE WATERS. LATEST WAVEWATCH3 ILLUSTRATES THIS OCCURRENCE. LONG TERM /TUESDAY THROUGH WEDNESDAY/... AS OF 330 AM SATURDAY...THIS PERIOD WILL BE HIGHLIGHTED BY SUPPRESSED UPPER RIDGING TO THE SOUTH WITH WEAK HIGH PRESSURE SPORADICALLY COVERING THE SE STATES. OVERALL WINDS WILL BE LIGHT...LESS THAN 10 KT. PREVAILING WIND DIRECTION WILL BE SOMEWHAT DIFFICULT TO FORECAST...COULD ALMOST GO WITH A VARIABLE DIRECTION AT TIMES. SIGNIFICANT SEAS WILL DROP TO AROUND 2 FT BY WED AS THE DECAYING ESE SWELL GIVES WAY TO LOCALLY PRODUCED WIND DRIVEN WAVES. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...NONE. NC...NONE. MARINE...NONE. && NEAR TERM...RJD SHORT TERM...DCH LONG TERM...DCH AVIATION...43
