The episode as NWS ILM wrote it up.
Late night thunderstorms developed along a subtle surface boundary.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Wilmington, NC wrote its last area forecast discussion before the first event at Jun 19, 10:09 PM EST, 1 hour 38 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON NC 1045 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 1045 PM SUNDAY...HAVE LOWERED POPS FOR THE REMAINDER OF THE OVERNIGHT. THE UPPER LEVEL DISTURBANCE WITHIN THE NW FLOW ALOFT SHOULD STAY 1 TO POSSIBLY 2 CWAS AWAY FROM THE ILM CWA. WITH THIS TRACK...THE MAJORITY IR NOT LL OF THE NOCTURNAL CONVECTION ASSOCIATED WITH THIS FEATURE...SHOULD ALSO REMAIN AWAY FROM THE ILM CWA. AM DISCOUNTING THE HRRR FOR THE TIME BEING. ITS LATEST RUN DID NOT IDENTIFY THE CONVECTION THAT AFFECTED THE ILM CWA THIS AFTERNOON. AND NOW IT WANTS TO PAINT A CONVECTIVE BULLSEYE ACROSS THE ILM CWA DURING THE PRE-DAWN HOURS OF MONDAY. THE ONLY HINT AT THIS POINT THAT CONVECTION COULD MOVE ACROSS THE FA IS THE CURRENT THUNDERSTORM ACTIVITY BLOWING UP ACROSS EASTERN TENNESSEE AT THE MOMENT. ITS A BIT FURTHER SOUTH THEN EXPECTED BUT WILL CONTINUE TO ADVERTISE IT TO PASS JUST NORTH OF THE FA DURING THE PREDAWN HOURS. LOWS AROUND 70 WEST OF I-95...TO THE MID 70S AT THE BEACHES. W TO NW FLOW IN THE LOWER LEVELS IS PROGGED TO CLIMB TO 20-35 KT. THIS WILL KEEP THE ATM MIXED AT THE SFC WHICH SHOULD PREVENT ANY FOG DEVELOPMENT...EVEN THE LOCATIONS THAT EXPERIENCED RAINFALL. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... AS OF 2:00 PM SUNDAY...FORECAST REMAINS IN THE LOW CONFIDENCE CAMP AS THE SYNOPTIC SITUATION WILL SLOWLY EVOLVE FROM A NORTHWEST FLOW WITH THE RIDGE TO THE WEST WITH THE AXIS OF THE RIDGE BUILDING OVERHEAD BY WEDNESDAY. AS USUAL...THE MODELS HAVE SLOWED DOWN THIS PROGRESSION. ANY NUMBER OF SHORTWAVES/OUTFLOW BOUNDARIES COULD INITIATE CONVECTION DURING THE PERIOD. AS WE HAVE SEEN THE PAST FEW DAYS...TIMING AND PLACEMENT OF THESE FEATURES IS ALL BUT IMPOSSIBLE. BASICALLY I HAVE POPS FOR MONDAY WITH HIGHER VALUES HIGHER WEST AND NORTH. FOR TUESDAY...LOOKS LIKE MORE OF A SEA BREEZE SITUATION BUT IF THE MODEL TRENDS CONTINUE...A NORTHWEST FLOW COULD CONTINUE. AT THE SURFACE...A WEAK AREA OF HIGH PRESSURE BUILDS IN LATE MONDAY WHICH SHOULD DECREASE DEWPOINTS BY A COUPLE OF DEGREES MITIGATING HEAT ADVISORY CONCERNS. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... AS OF 2:00 PM SUNDAY...BLAZING HEAT PERSISTS INTO WEDNESDAY AS UPPER RIDGE REMAINS OVER THE SOUTHEAST. IT WILL BE PROGRESSING TO THE EAST HOWEVER IN RESPONSE TO A TROUGH BROADENING AND PROGRESSING INTO THE WRN GREAT LAKES AND UPPER MS VALLEY. AT THE SURFACE A WELL DEVELOPED PIEDMONT TROUGH WILL BE IN PLACE BUT THE SUPPRESSIVE EFFECTS FROM THE RIDGE ABOVE WILL PRECLUDE ANY RAINFALL. AS THE TROUGH/RIDGE PATTERN MOVES EAST ON THURSDAY SOME MEAGER HEIGHT FALLS WILL ADVECT EAST INTO THE CAROLINAS. THIS WILL TEMPER THE HEAT SLIGHTLY BUT STILL NOT PROVIDE ENOUGH CAP RELIEF TO LEAD TO ANY MEANINGFUL RAINFALL CHANCES. MID LEVEL CYCLONIC FLOW OVER THE CAROLINAS ON FRIDAY NOW APPEARS TO BE LESS INVASIVE THAN BEFORE. AS SUCH...THE COLD FRONT NOW MAKES LESS SOUTHWARD PROGRESS TOWARDS THE AREA AND NO LONGER APPEARS TO BE A SIGNIFICANT POP-ENHANCER LOCALLY. A FEW MORE DEGREES MAY BE SHAVED OFF OF HIGH TEMPERATURES HOWEVER THEY WILL STILL REMAIN ABOVE NORMAL ESP BY DAY. THERE IS MUCH UNCERTAINTY WITH THE WEEKEND FORECAST AS SOME GUIDANCE LIFTS OUT THE MID LEVEL TROUGH. OTHER GUIDANCE HALTS THE LONGITUDINAL PROGRESSION AND KEEPS THE TROUGH CLOSE TO THE APPALACHIANS WHILE THE BERMUDA HIGH STRENGTHENS. SOME EVEN GO SO FAR AS TO HINT THAT THIS BEGINS TO DRAW UP SOME TROPICAL MOISTURE. GIVEN THE DROUGHT WILL NOT SHOW ANYTHING OF THE SORT AND KEEP TEMPS AND POPS PRETTY CLOSE TO CLIMO. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... AS OF 00Z...CONVECTION HAS DIMINISHED...AND A SECONDARY BATCH WELL WEST OF THE REGION HAS ALSO WEAKENED. THE HRRR MODEL DOES BRING A SECOND BATCH OF CONVECTION TO THE COAST WELL AFTER MIDNIGHT...BUT FAIRLY LOW CONFIDENCE IN THIS SCENARIO. THE WINDS SHOULD STAY UP ENOUGH OVERNIGHT TO PRECLUDE ANY FOG...OTHER THAN POCKETS OF MVFR IN MIST AND HAZE. MONDAY...CONTINUED VFR WITH WESTERLY FLOW. ISOLATED CONVECTION IS EXPECTED TO REFIRE IN THE AFTERNOON. EXTENDED OUTLOOK...ISOLATED THUNDERSTORMS POSSIBLE EACH AFTERNOON AND EVENING THROUGH THE PERIOD. && .MARINE... NEAR TERM /THROUGH TONIGHT/... AS OF 1045 PM SUNDAY...SW-NW FLOW IN THE LOWER LEVELS OF THE ATMOSPHERE ARE PROGGED TO RANGE BETWEEN 25 TO 40 KT OVER THE WATERS. AT THE SFC...WILL BE LOOKING AT SW 15-20 KT WITH SOME HIGHER GUSTS MIXING DOWN. SEAS WILL BE MAINLY COMPRISED OF THE 4 TO 6 SECOND SHORT PERIOD WIND DRIVEN WAVES RUNNING AT HEIGHTS OF 3 TO 5 FT. A SMALL CRAFT EXERCISE CAUTION WILL CONTINUE. SHORT TERM /MONDAY THROUGH TUESDAY/... AS OF 2:00 PM SUNDAY...EXPECT A FRAILLY STRONG...FOR THIS TIME OF YEAR...WESTERLY FLOW INITIALLY. SPEEDS SHOULD BE HOVERING AROUND 20 KNOTS THANKS TO LOW LEVEL JETTING. EXPECT A WIND SHIFT TO THE NORTHEAST BY MONDAY EVENING AS A WEAK HIGH MOVES IN FROM THE NORTHEAST. FOR TUESDAY...A WEAK PRESSURE PATTERN WILL LEAD TO MESOSCALE FEATURES...THE SEA BREEZE AND POSSIBLY AN OUTFLOW BOUNDARY OR TWO DRIVING THE WINDS. AS FOR SEAS...EXPECT 2-4 FEET INITIALLY WITH THE STRONGER WINDS SUBSIDING SLIGHTLY TO 2-3 FEET TUESDAY. LONG TERM /WEDNESDAY THROUGH FRIDAY/... AS OF 2:00 PM SUNDAY...SOUTHWESTERLY WINDS WILL REMAIN RATHER UNFETTERED IN THE 10 TO 15 KT RANGE FOR MOST OF THE PERIOD AS BERMUDA HIGH AND PIEDMONT TROUGH REMAIN MORE OR LESS IN PLACE. SEAS WILL REMAIN IN THE 2 TO 3 OR OCCASIONALLY 4 FT RANGE BEING COMPRISED LARGELY OF A WIND WAVE BUT ALSO A SMALL SE SWELL COMPONENT. A SMALL CHANGE MAY BE IN STORE FOR FRIDAY AS A MID LEVEL TROUGH MOVES INTO THE CAROLINAS. THIS WILL HAVE THE EFFECT OF PUSHING THE PIEDMONT TOUGH EAST CLOSER TO THE COAST. THIS WILL CAUSE A SLIGHT DISRUPTION OF THE BERMUDA HIGH COMPONENT OF THE SOUTHWESTERLY FLOW AND LEAD TO A SLIGHT WEAKENING OF THE WINDS. ANY CHANGES TO SEAS WILL BE MINOR...PERHAPS THE OCCASIONAL 4 FT WAVES WELL OFFSHORE WILL GO AWAY. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...NONE. NC...NONE.
