NWS Wilmington, NC wrote its last area forecast discussion before the first event at Aug 11, 2:07 PM EST, 13 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON NC 307 PM EDT SUN AUG 11 2013 .SYNOPSIS... WARM AND MOIST HIGH PRESSURE WILL CONTINUE ITS GRIP ON THE REGION THROUGH EARLY TUESDAY. A COLD FRONT WILL MOVE INTO THE AREA LATE TUESDAY AND WILL BECOME STATIONARY ALONG THE CAROLINA COAST THURSDAY THROUGH NEXT SUNDAY. BEGINNING TUESDAY NIGHT THE REGION CAN EXPECTED A 5 DAY PERIOD OF ABOVE AVERAGE RAINFALL AND COOLER THAN NORMAL HIGHS. && .NEAR TERM /THROUGH TONIGHT/... AS OF 3 PM SUNDAY...ISOLATED TO SCATTERED TSTMS WILL CONTINUE TO MARCH EAST ACROSS MAINLY OUR NC ZONES THROUGH AFTERNOON INTO EARLY EVENING. DRY AND WARM AIR ALOFT APPEARS TO BE TAKING ITS TOLL ON CONVECTION OVER OUR SC ZONES THIS AFTERNOON AND DO NOT EXPECT THIS TREND TO CHANGE VERY MUCH. SEA BREEZE ACTIVITY CANNOT BE RULED OUT EXPANDING SW INTO THE COASTAL INTERIOR OF HORRY COUNTY. SHOWERS AND TSTMS MOVING EAST COLLIDING WITH THE SEA BREEZE FRONT MAY PULSE UPWARD TO PRODUCE STRONG GUSTY WINDS THROUGH THE AFTERNOON HOURS. OTHERWISE EXPECT REDUCTION OF SURFACE HEATING INTO EARLY EVENING WILL SAP CONVECTIVE STRENGTH AND COVERAGE WITH LITTLE UPPER SUPPORT READILY AVAILABLE ACROSS THE AREA. A WEAK SURFACE TROUGH OVER OUR NORTHERN ZONES COULD SUSTAIN ISOLATED ACTIVITY THROUGH PORTIONS OF THE EVENING AND WILL RETAIN LOW-END POP VALUES THERE. MIN TEMPS OVERNIGHT SIMILAR TO LAST NIGHT AND RELATIVELY MILD...UPPER 70S ALONG AND NEAR THE COAST AND MIDDLE 70S OVER MOST OF THE INTERIOR. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... AS OF 3 PM SUNDAY...THIS SHORT HOT SPELL FOR OUR AREA APPEARS TO BECOMING TO A QUICK END AS A COLD FRONT WILL MOVE ACROSS THE REGION LAST TUESDAY NIGHT AND MOVE TO THE COAST. BUT FOR THIS PERIOD IT WILL CONTINUE TO HOT AND HUMID WITH THE 850 MB TEMPERATURE REMAINS AT 19 DEGREES CELSIUS. MAXIMUM TEMPERATURES ARE EXPECTED TO REACH THE MID 90S INLAND AND NEAR 90 AT THE BEACHES. HEAT INDICES AGAIN WILL APPROACH 103 TO 104 DEGREES MAINLY FOR AREA NEAR AND WEST OF INTERSTATE 95. CONVECTION IS EXPECTED TO BE SCATTERED AGAIN WITH THE BEST CHANCES OVER THE NORTHERN TIER OF COUNTIES IN NORTH CAROLINA. CHANCES WILL INCREASE ON TUESDAY NIGHT AS FRONTAL BOUNDARY APPROACHES REGION FROM THE NORTH. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... AS OF 3 PM SUNDAY...AN UNUSUALLY PERSISTENT UPPER TROUGH WILL DEVELOP ACROSS THE EASTERN HALF OF THE NATION WEDNESDAY. A SURFACE COLD FRONT WILL DROP SOUTHWARD INTO THE EASTERN CAROLINAS... INTERCEPTING A DEEP FLOW OF TROPICAL MOISTURE WITH PRECIPITABLE WATER VALUES REMAINING IN THE 2.0 TO 2.4 INCH RANGE THROUGH THE ENTIRE EXTENDED FORECAST PERIOD. THE JET STREAM WILL BECOME ENHANCED JUST EAST OF THE UPPER TROUGH WITH A JET MAX DEVELOPING FROM SOUTHERN VIRGINIA INTO THE CANADIAN MARITIMES. THE EASTERN CAROLINAS WILL REMAIN WITHIN THE RIGHT-ENTRANCE REGION OF THIS JET MAX THROUGH VIRTUALLY ALL FIVE DAYS WED-SUN...WITH ENHANCED SYNOPTIC LIFT HELPING OUR CHANCES FOR RAIN. THE SURFACE COLD FRONT SHOULD ARRIVE IN THE EASTERN CAROLINAS WEDNESDAY AFTERNOON...STALLING ACROSS EASTERN SOUTH CAROLINA WEDNESDAY NIGHT. BOTH THE 12Z GFS AND 00Z ECMWF SHOW A WAVE OF LOW PRESSURE DEVELOPING ACROSS THE INTERIOR SOUTHEAST WEDNESDAY NIGHT...LIFTING THE FRONT BACK TO THE NORTH THURSDAY. AS THIS WAVE PUSHES EAST THROUGH NORTH CAROLINA THURSDAY NIGHT THE SURFACE FRONT WILL AGAIN SAG SOUTHWARD TO THE COAST. WITH AN ALMOST SATURATED TROPOSPHERE...THE SURFACE FRONT NEARBY...AND UPPER LEVEL DIVERGENCE PROVIDED BY THE FAVORABLY POSITIONED 250 MB JET...I HAVE BUMPED POPS INTO THE LIKELY (60-70 PERCENT) RANGE FOR EACH 12-HOUR PERIOD WEDNESDAY THROUGH THURSDAY NIGHT. A THREAT OF FLOODING SHOULD DEVELOP DURING THIS PERIOD GIVEN THE SUPERPOSITION OF ALL THESE VERY FAVORABLE PRECIPITATION PARAMETERS. THE SURFACE WAVE WILL RIPPLE EAST OF THE CAROLINAS BY FRIDAY MORNING POTENTIALLY PLACING THE CAROLINAS WITHIN A RAINFALL LULL...AT LEAST IN A RELATIVE SENSE. THE ATMOSPHERE SHOULD OTHERWISE REMAIN FAVORABLE FOR CONVECTION ALOFT. ANY SUPPRESSION BEHIND THE SURFACE WAVE SHOULD DIMINISH BY SATURDAY AND SHOWERS AND THUNDERSTORMS MAY BECOME A LITTLE MORE WIDESPREAD DIURNALLY INTO SUNDAY. WITH ALL THE CLOUDS AND PRECIPITATION AROUND...DIURNAL TEMPERATURE RANGES WILL REMAIN CONSTRICTED THROUGH THE PERIOD. ASIDE FROM WEDNESDAY WHEN HIGHS WILL REACH THE UPPER 80S THE REMAINDER OF THE PERIOD SHOULD SEE HIGHS MAINLY IN THE MID 80S WITH OVERNIGHT LOWS 68-72. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... AS OF 18Z...LFC'S STILL QUITE HIGH...ALONG WITH FAIRLY WARM 500 MB TEMPS. SHOULD SEE ISOLATED TO SCATTERED CONVECTION FIRING THIS AFTERNOON. CONVECTION MAY LINGER INTO THE EVENING AS THE FRONT STALLS JUST TO OUR NORTHWEST. WINDS AT THE BOUNDARY LAYER AND AT THE SURFACE WILL BE TOO STRONG TO SUPPORT ANYTHING OTHER THAN LIGHT FOG OVERNIGHT. MONDAY...CONTINUED WEST SOUTHWEST FLOW WITH POSSIBLE CONVECTION AT THE END OF THE FORECAST PERIOD. EXTENDED OUTLOOK...SCATTERED SHOWERS/T-STORMS MONDAY AND TUESDAY... BECOMING MORE WIDESPREAD ON WEDNESDAY AND THURSDAY. && .MARINE... NEAR TERM /THROUGH TONIGHT/... AS OF 3 PM SUNDAY...MODERATE BERMUDA HIGH PRESSURE PREVAILS OVER THE WATERS WITH SW WINDS 10-15 KT AND 2-3 FOOT SEAS MOST LOCALS. SEAS WILL BE A PATCHWORK OF SW WAVES 1-2 FEET AT 4-5 SECONDS AND SE WAVES 1-2 FEET AT 8-9 SECONDS...AND THIS REGIME SHOULD PREVAIL THROUGH THE OVERNIGHT PERIOD. STEERING WINDS COULD GUIDE SHOWERS AND ISOLATED STORMS EASTWARD OVER THE NEAR SHORE WATERS THROUGH THE EARLY EVENING...MAINLY FROM CAPE FEAR NORTHWARD. SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... AS OF 3 PM SUNDAY...HIGH PRESSURE WILL SLOWLY GIVE WAY TO A COLD FRONT THAT WILL MOVE TO THE COASTAL WATERS LATE TUESDAY NIGHT AND STALL. THIS MEANS THE WATERS WILL SEE A SOUTHWEST FLOW OF 10 TO 15 KNOTS AND AS THE BOUNDARY MOVES TO THE COAST THE WINDS WILL DECREASE TO 5 TO 10 KNOTS. SEAS WILL CONTINUE TO RANGE BETWEEN 2 AND 3 FEET WITH THE SOUTHWEST FLOW. LONG TERM /WEDNESDAY THROUGH FRIDAY/... AS OF 3 PM SUNDAY...1023 MB CANADIAN HIGH PRESSURE OVER THE WESTERN GREAT LAKES WILL PUSH A COLD FRONT SOUTHWARD AND INTO THE CAROLINA COASTAL WATERS LATE WEDNESDAY AFTERNOON. THIS FRONT WILL LIKELY BE ACCOMPANIED BY SHOWERS AND THUNDERSTORMS BOTH ALONG AND BEHIND THE SHALLOW FRONT...LASTING INTO WEDNESDAY NIGHT. SOUTHWEST WINDS DURING THE DAY WILL SHIFT MORE NORTHERLY...ESPECIALLY NORTH OF GEORGETOWN. LOW PRESSURE DEVELOPING ALONG THE FRONT OVER THE INTERIOR SOUTHEAST STATES WILL PREVENT THE FRONT FROM SAGGING TOO FAR SOUTH...AND IN FACT MODELS ARE INDICATING THE FRONT WILL RETURN NORTH AGAIN DURING THE DAY THURSDAY WITH SOUTH WINDS REDEVELOPING ALONG MOST OF THE COASTLINE. SHOWERS AND THUNDERSTORMS WILL LIKELY ACCOMPANY THIS REGION OF UNSETTLED WEATHER. AS THE LOW MOVES EAST ALONG THE INLAND FRONT THURSDAY AND ACROSS THE EASTERN CAROLINAS THURSDAY NIGHT...LOOK FOR SHOWERS AND THUNDERSTORMS TO CONTINUE. OBVIOUSLY WITH SO MUCH THUNDERSTORM ACTIVITY FORECAST LOCAL WINDS AND SEAS WILL VARY TREMENDOUSLY. AS AN AVERAGE...SEA HEIGHTS SHOULD AVERAGE 2-4 FT...HIGHEST DURING THE DAY WEDNESDAY WITH THE SOUTHWEST WINDS AHEAD OF THE FRONT...AND AGAIN THURSDAY NIGHT DURING A PERIOD OF STRONGER SOUTH WINDS AHEAD OF THE INLAND SURFACE LOW. && .ILM WATCHES/WARNINGS/ADVISORIES...
