NWS Wilmington, NC wrote its last area forecast discussion before the first event at Jun 19, 9:58 AM EST, 2 hours 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON NC 1058 AM EDT SUN JUN 19 2011 .SYNOPSIS... SEVERAL WEAK DISTURBANCES ALOFT WILL BRING SCATTERED THUNDERSTORMS TO THE EASTERN CAROLINAS THROUGH TONIGHT...AND SOME OF THESE STORMS COULD PRODUCE DAMAGING WINDS. BUILDING HIGH PRESSURE IN THE UPPER ATMOSPHERE WILL PRODUCE HOT CONDITIONS ACROSS THE REGION EARLY TO MID WEEK. MUGGY WEATHER AND TROPICAL MOISTURE MAY BRING A BETTER CHANCE OF MORE SUBSTANTIAL RAIN LATE IN THE WEEK. && .NEAR TERM /THROUGH TONIGHT/... AS OF 1058 AM SUNDAY...AS ADVERTISED PREVIOUSLY...SCATTERED STRONG TSTMS CAPABLE OF INDUCING WIND DAMAGE LATE THIS AFTERNOON THROUGH EVENING APPEARS FEASIBLE. PATTERN SIMILAR TO YESTERDAY WHERE COMPLEX OF CONVECTION HOLDS INTACT OVER THE MOUNTAINS ENCOUNTER CENTRAL NC AND SC DURING PEAK DIURNAL HEATING. STORM MOTION FROM NW TO SE ABOUT 20 KNOTS EXPECTED LATE TODAY INTO TONIGHT. VERY GOOD SURFACE HEATING WILL BOOST CONVECTIVE POTENTIAL ENERGY...AND ALL OF OUR FORECAST AREA REMAINS IN A SLIGHT RISK OF SEVERE WEATHER TODAY. 12Z MODEL RUNS MOSTLY IN AGREEMENT THAT ANY STRONG CONVECTION WILL BE LATE AFTN AND OVERNIGHT. WATER VAPOR ANALYSIS SHOWS A SHORT-WAVE TRACKING ACROSS EASTERN VA AND CENTRAL NC...AND A FEW SHOWERS ARE DEVELOPING IN VAPOR GRADIENTS WHERE VERTICAL CIRCULATIONS RESIDE. SEA BREEZE WILL REMAIN NEAR THE COAST TODAY IN MOSTLY WESTERLY FLOW...WILL RETAIN SLIGHT CONVECTIVE CHANCES NEAR THE COAST AND WELL INLAND THROUGH AFTERNOON...THEN EXPANDING AREA-WIDE AND INCREASING THE POP THROUGH EVENING AS THE MAIN UPPER PERTURBATION CROSSES THE REGION. && .SHORT TERM /MONDAY THROUGH TUESDAY/... AS OF 3 AM SUNDAY...UPPER RIDGE AXIS ROUGHLY OVERHEAD BY TUESDAY...PROVIDING A CLASSIC SETUP FOR EXTREME HEAT WITH DEEP WNW FLOW. THE OFFSHORE LOW-LEVEL TRAJECTORY MEANS THAT THE HEAT WILL EXTEND ALL THE WAY DOWN TO THE COAST...WITH HIGHS IN THE MID 90S EVEN ALONG THE GRAND STRAND...AND UPPER 90S TO AROUND 100 WELL INLAND. BIGGEST QUESTION MARK IS WHETHER DEWPOINTS WILL MIX DOWN ENOUGH TO KEEP HEAT INDICES BELOW ADVISORY CRITERIA. BEST GUESS AT THIS POINT IS THAT DEWPOINTS WILL BE AROUND 70F AT MAX HEATING...SUPPORTING HEAT INDICES CLOSE TO THE 105 THRESHOLD ACROSS INLAND SC LOCATIONS...AND JUST ABOVE 100 ELSEWHERE. MID LEVELS ARE WARM AND DRY ENOUGH TO LIMIT CONVECTIVE POTENTIAL TO JUST SLIGHT CHANCE EACH AFTERNOON. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... AS OF 3 AM SUNDAY...LOOK FOR ONE MORE DAY OF TEMPS NEAR 100 INLAND ON WEDNESDAY BEFORE THE UPPER RIDGE STARTS TO BREAK DOWN. MODEST HEIGHT FALLS WILL TEMPER THE HEAT SLIGHTLY...WITH TEMPS A COUPLE DEGREES COOLER EACH DAY BUT STILL GETTING INTO THE 90S AWAY FROM THE COAST. WEAK TROFINESS ALOFT FRI-SAT AS A CLOSED LOW OPENS UP OVER THE GREAT LAKES...AND A FRONT MAKES ITS WAY INTO THE CAROLINAS. POPS WILL TREND UP FROM SLIGHT OR NO CHANCE WED- THU...TO THE LOW CHANCE CATEGORY IN THE AFTERNOONS ON FRI-SAT. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... AS OF 12Z...TERMINALS ARE VFR THIS MORNING AND VFR IS EXPECTED THROUGH 18Z. ISOLATED CONVECTIVE SHOWERS NEAR LBT ARE MOVING RAPIDLY EAST AND SEEM TO BE ASSOCIATED WITH NARROW BANDS OF LOW AND MID LEVEL MOISTURE...NOT HANDLED WELL BY THE MODELS. CONVECTIVE POTENTIAL WILL BE BEST EAST OF THE LBT TERMINALS...THEN ACTIVITY SHOULD MOVE WEST AND DISSIPATE BEFORE REACHING THE ILM/CRE TERMINALS. AT THE COASTAL TERMINALS DUE TO LOW AND MID LEVEL WESTERLY FLOW THIS MORNING DO NOT EXPECTED ANY SIGNIFICANT AREAS OF CONVERGENCE TO DEVELOP. THIS COMBINED WITH RELATIVELY LOW DEWPOINTS AND LITTLE OVERALL LOW LEVEL MOISTURE DO NOT EXPECT ANY CONVECTIVE ACTIVITY TO DEVELOP DESPITE UNSTABLE CONDITIONS. BUT THIS AFTERNOON AS THE SEA BREEZE DEVELOPS AND CONVECTIVE TEMPERATURES ARE REACHED CONVERGENCE ALONG THE BOUNDARY COULD LEAD TO ISOLATED CONVECTIVE DEVELOPMENT. DUE TO THE ISOLATED NATURE OF THE ACTIVITY WILL ONLY INDICATE CB IN COASTAL TAFS BY 18Z ATTM. THE BEST CHANCE OF THUNDERSTORMS SHOULD OCCUR NEAR THE FLO/LBT TERMINALS LATE THIS AFTERNOON. THE AREA OF ACTIVITY SHOULD MOVE SOUTHEAST TO THE COASTAL TERMINALS THIS EVENING AND MAY NOT DISSIPATE AS YESTERDAY EVENING DUE TO BETTER UPPER SUPPORT AND THE LACK OF A STABILIZING MARINE LAYER INLAND. EXTENDED OUTLOOK...ISOLATED THUNDERSTORMS POSSIBLE EACH AFTERNOON AND EVENING THROUGH THE PERIOD. && .MARINE... NEAR TERM /THROUGH TONIGHT/... AS OF 7 AM SUNDAY...AN EAST-TO-WEST ORIENTED RIDGE OF HIGH PRESSURE WILL EXTEND FROM THE FLORIDA KEYS ACROSS THE NORTHERN BAHAMAS AND OFF TO THE EAST THROUGH TONIGHT. THIS WILL KEEP A MAINLY WEST SYNOPTIC FLOW ACROSS THE CAROLINAS...WITH LOCAL SEABREEZE EFFECTS EXPECTED TO BACK THOSE WIND DIRECTIONS AROUND TO THE SOUTHWEST NEARSHORE THIS AFTERNOON AND EARLY THIS EVENING. A COLD FRONT WILL REMAIN JUST NORTH OF THE AREA THROUGH TONIGHT. LOWER PRESSURES ALONG THE FRONT WILL CREATE A TIGHTER PRESSURE GRADIENT AND WILL HELP PRODUCE WIND SPEEDS AS HIGH AS 15-20 KNOTS THIS AFTERNOON. GUSTS WITHIN THE SEABREEZE ZONE COULD REACH AS HIGH AS 25 KNOTS. A SECOND THREAT IS THE POTENTIAL FOR THUNDERSTORMS TONIGHT. MODELS ARE SHOWING A SIMILAR SITUATION TO SATURDAY NIGHT WHERE INLAND THUNDERSTORMS PRODUCE STRONG WINDS DOWN TO WITHIN ABOUT 20-30 MILES OF THE COAST. WEAKER STORMS THEN MAY PERSIST ACROSS THE COASTLINE AND OUT OVER THE OCEAN. LATER MODEL RUNS WILL HOPEFULLY PROVIDE ADDITIONAL CLARITY AS TO THE POTENTIAL FOR STORMS TONIGHT. HEALTHY WIND SPEEDS OVER THE PAST 24 HOURS HAVE PUSHED SEAS TO 5 FEET AT THE FRYING PAN SHOALS BUOY...AND TO 3-4 FT CLOSER TO SHORE. SMALL FLUCTUATIONS ARE EXPECTED IN SEA HEIGHTS TODAY...BUT AN AVERAGE OF 3-4 FT IS EXPECTED THROUGH TONIGHT. THE HIGHEST SEAS...NEAR 5 FEET AT TIMES...MAY OCCUR WITHIN 20 MILES OF SHORE SOUTHEAST OF CAPE FEAR. SHORT TERM /MONDAY THROUGH TUESDAY/... AS OF 3 AM SUNDAY...PROXIMITY OF A SURFACE TROUGH AXIS TO THE COAST WILL KEEP MORE OF A WESTERLY COMPONENT TO THE LOW-LEVEL FLOW... ESPECIALLY ON MONDAY. THE OFFSHORE TRAJECTORY MAY EVEN OVERWHELM THE SEABREEZE...SO EXPECT LIGHT WESTERLY WINDS TO PERSIST FOR MUCH OF MONDAY AND MONDAY NIGHT. BY TUESDAY THE WESTERLY COMPONENT WEAKENS ENOUGH TO ALLOW MORE TYPICAL SEABREEZE PROCESSES TO TAKE HOLD...WITH SW WINDS MAXIMIZED LATE AFTERNOON/EARLY EVENING. WIND SPEEDS SHOULD STILL BE LIMITED TO 10-15 KT...AND SEAS 2-3 FT IN A SHORT-PERIOD WIND WAVE. LONG TERM /TUESDAY NIGHT THROUGH THURSDAY... AS OF 3 AM SUNDAY...SW GRADIENT TIGHTENS UP A BIT AND WE SEE A RETURN OF THE SEABREEZE OSCILLATION...WITH LIGHT WESTERLY WINDS EACH MORNING...AND THEN BACKING AND INCREASING IN THE AFTERNOON AND EVENING. SOLID 15 KT EACH EVENING WILL BE ENOUGH TO BUMP SEAS UP TO 3-4 FT...MAINLY IN WIND WAVE BUT WITH A WEAK SE SWELL COMPONENT. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...NONE. NC...NONE.
