A thunderstorm did produce nickel size hail just northwest of Florence.
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 Sep 12, 6:52 PM EST, 1 hour 13 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON NC 752 PM EDT MON SEP 12 2011 .SYNOPSIS... AN UPPER TROUGH WILL PASS ACROSS THE CAROLINAS OVERNIGHT. A WEAK PRESSURE PATTERN WILL EXIST AT THE SURFACE THROUGH MID WEEK. AN INCREASED RIP CURRENT THREAT CAN BE EXPECTED THIS WEEK AS TROPICAL CYCLONE MARIA PASSES WELL OFFSHORE OF THE EAST COAST. A STRONG COLD FRONT IS EXPECTED TO BRING COOLER TEMPERATURES LATE IN THE WEEK. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... AS OF 8:00 PM MONDAY...ISOLATED BUT STRONG CONVECTION HAS FINALLY FADED DOWN TO A FEW SPOTTY SHOWERS. IT WAS A VERY BOUNDARY RICH ENVIRONMENT THIS AFTERNOON AND EVENING WITH MULTIPLE OUTFLOWS INTERACTING WITH EACH OTHER AND THE SEA BREEZE FRONT. ALSO...COLD POOL ALOFT ALLOWED SOME HAILERS TO DEVELOP AS WELL AS SOME STRONG TO SEVERE LEVEL DOWNDRAFTS. ISSUED ONE SVR IN HORRY COUNTY WHICH SEEMS TO HAVE VERIFIED. REST OF NIGHT SHOULD BE RELATIVELY QUIET...WITH ISOLATED SHOWERS REMAINING A POSSIBILITY THROUGH THE EVENING HOURS. DO NOT EXPECT ANY MORE STRONG CONVECTION. HAVE UPDATED FORECAST AND GRIDDED DATABASE TO FINE TUNE PRECIP COVERAGE AND CHANCES. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/... AS OF 3 PM MONDAY...MID TO UPPER TROUGH WILL BE MOVING FURTHER EAST THROUGH THE PERIOD AS A WEAK PRESSURE PATTERN PERSISTS AT THE SURFACE. LOCAL AREA WILL REMAIN ON BACK END OF THIS TROUGH WITH INCREASED SUBSIDENCE THROUGH THE PERIOD...ALTHOUGH NAM DOES SHOW A LITTLE RIPPLE IN THE H5 NW FLOW COMING THROUGH TUES AFTERNOON. MOISTURE WILL BE VERY LIMITED ONCE AGAIN BUT AS THIS FINE FEATURE MOVES THROUGH DURING PEAK HEATING...WILL INCLUDE JUST MENTIONABLE POPS IN FORECAST FOR A FEW HOURS MAINLY ALONG SEA BREEZE BOUNDARY TUES AFTN. 12Z SOUNDINGS SHOWING A LITTLE GREATER DEPTH OF SATURATED LAYER RUNNING BETWEEN 5-7 K FT. OVERALL WILL SEE MORE IN THE WAY OF AFTN CU DEVELOPMENT CLUSTERED ALONG SEA BREEZE BOUNDARY PRODUCING MOSTLY SUNNY TO PARTLY CLOUDY SKIES. OTHERWISE WARM AND DRY WEATHER EXPECTED THROUGH MID WEEK. TEMPS WILL CONTINUE TO RUN ABOVE NORMAL...WITH READINGS IN THE MID TO UPPER 80S AND OVERNIGHT LOWS IN THE LOW TO MID 60S. && .LONG TERM /THURSDAY THROUGH MONDAY/... AS OF 3 PM MONDAY...BIGGEST QUESTION IS THE LONGEVITY AND SENSIBLE WEATHER IMPACT OF THE COLD AIR DAMMING EPISODE THAT WILL BEGIN ON FRIDAY AND CONTINUE INTO THE WEEKEND. LOW-LEVEL WEDGE SIGNATURE IS QUITE STRONG...BUT UPPER PATTERN IS FLAT AND ANY DISTURBANCES WILL BE QUITE DIFFICULT TO TIME. AM MOST CONFIDENT IN THE EXTENSIVE CLOUD COVER AND RESULTING BELOW NORMAL DAYTIME TEMPERATURES...ESPECIALLY ON SATURDAY WHEN NEGATIVE DEPARTURES COULD BE IN THE DOUBLE DIGITS. BELIEVE THAT THE EXTENDED GFS MOS IS CATCHING UP WITH THE ANOMALOUSLY COOL DAYTIME TEMPS...AND EVEN THOUGH WE MAY NEED TO HEDGE DOWN FARTHER...10 DEGREES BELOW NORMAL SHOULD CONVEY THE TREND 5 DAYS OUT. MIN TEMPS ALSO A FEW DEGREES BELOW NORMAL...BUT CURRENT FORECAST IS ON THE WARM SIDE OF GUIDANCE DUE TO EXTENSIVE CLOUD COVER. HAVE OPTED TO TAPER POPS DOWN TO SLIGHT CHANCE OR SILENT RANGES BY SATURDAY NIGHT...BUT CLOUD COVER WILL LINGER FOR MOST OF THE WEEKEND. && .AVIATION /00Z TUESDAY THROUGH SATURDAY/... AS OF 00Z...POTENTIAL MVFR/IFR RESTRICTIONS DUE TO FOG OVERNIGHT INTO EARLY TUESDAY MORNING...OTHERWISE EXPECT VFR THROUGH VALID PERIOD. MOST TERMINALS EXPERIENCED RAINFALL AFTER ISOLATED CONVECTION STRETCHED ACROSS THE AREA THIS EVENING. WITH NEARLY CALM WINDS...RADIATIONAL COOLING WILL BE IDEAL OVERNIGHT. FOR NOW...HAVE INCLUDED MVFR FOG AT ALL TERMINALS...WITH WINDOW OF IFR/LIFR POSSIBLE AT THE INLAND TERMINALS. ONLY POTENTIAL INHIBITING FACTOR IS THE INFLUENCE OF LEFTOVER HIGH-CLOUD CLOUDS. EXPECT ANY DEVELOPED FOG TO DISSIPATE AFTER DAYBREAK...GIVING WAY TO VFR THROUGH VALID PERIOD. WINDS TUESDAY MORNING THROUGH MIDDAY WILL BE GENERALLY NORTH AROUND 5KTS...SHIFTING MORE SOUTHERLY WITH AFTERNOON SEABREEZE. WINDS WILL DECREASE BECOMING NEARLY CALM BY LATE EVENING. EXTENDED OUTLOOK...EXPECT MORNING FOG AND ISOLATED AFTERNOON CONVECTION WEDNESDAY AND THURSDAY. EXPECT A FAIRLY UNSEASONABLY STRONG COLD FRONT TO BRING UNSETTLED WEATHER FRIDAY INTO SATURDAY. && .MARINE... NEAR TERM /THROUGH TONIGHT/... AS OF 8:00 PM MONDAY...LATEST COASTAL AND BUOY OBS SHOW 2 TO 3 FT SEAS AND GENERALLY LIGHT WINDS. WIND DIRECTIONS STILL ALL OVER THE COMPASS DUE TO EARLIER CONVECTION MOVING ACROSS THE WATERS...BUT WILL SETTLE ON A SOUTHERLY DIRECTION WHILE REMAINING LIGHT LATER THIS EVENING. PREVIOUS DISCUSSION FOLLOWS: MARIA WAVE ENERGY HAS ARRIVED ON THE NC/SC BEACHES...BETWEEN 1-2 FEET AND RUNNING IN 13 SECOND INTERVALS. THE REMAINDER OF SE WAVE ENERGY WAS SPREAD OUT OVER A WIDE RANGE OF PERIODS LESS THAN 13 SECONDS. A RELATIVELY NON-DESCRIPT PRES PATTERN WILL PROMOTE LIGHT WINDS THROUGH THE NEAR TERM PERIOD ASIDE FROM AFTN SEA-BREEZE GUSTINESS OF 15 KNOTS. OVERNIGHT THE SEA-SPECTRUM WILL BECOME MOSTLY LONG PERIOD SE SWELL. MARINERS SHOULD EXPECT ENHANCED SHOALING AND PERHAPS BREAKING WAVES IN AREAS THAT ARE NORMALLY CALMER FOR A 2-3 FOOT SEA STATE. MARIA SWELL WILL NOT INCREASE MUCH OVERNIGHT SINCE SHE STRUGGLED WITH INTENSITY HISTORICALLY...THUS 2-4 FT SEAS OVERNIGHT AND HIGHEST VERY OUTER PORTION. A FEW TSTMS OUGHT TO BE EXPECTED BY LATE TONIGHT AS AN UPPER TROUGH MOVES OVER THE MILD OCEAN WATERS. EXPECT THE WESTERN EDGE OF THE GULF STREAM TO LIGHT UP LATE TONIGHT BENEATH A LINE OF TSTMS. SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... AS OF 3 PM MONDAY...MID TO UPPER TROUGH WILL BE MOVING FURTHER EAST THROUGH THE PERIOD AS A WEAK PRESSURE PATTERN PERSISTS AT THE SURFACE. THEREFORE LAND/SEA BREEZE INTERACTIONS WILL BE THE RULE THROUGH MID WEEK. OVERALL WINDS WILL 10 KTS OR LESS WITH SLIGHT INCREASE IN ONSHORE SEA BREEZE IN THE AFTERNOON. SEAS WILL CONTINUE TO BE DOMINATED BY LONGER PERIOD SWELLS UP AROUND 11 TO 13 SECONDS FROM MARIA THROUGH MID WEEK. WNA SHOWS A SLOW DECREASE IN SWELLS THROUGH TUES AFTN BUT ANOTHER SPIKE UP TUES EVENING NEAR 12 SECONDS. EXPECT SEAS TO RUN IN THE 2 TO 4 FT RANGE. LONG TERM /THURSDAY THROUGH SATURDAY/... AS OF 3 PM MONDAY...MAIN ISSUE ON THURSDAY IS STILL THE QUESTION OF SWELL FROM MARIA...BUT THAT FORECAST IS TONED DOWN THANKS TO A WEAKER AND EVEN MORE DISTANT STORM. WILL STICK WITH 3-4 FT THROUGH THURSDAY NIGHT...BUT THEN THINGS DETERIORATE FRIDAY BEHIND A STRONG COLD FRONT AND WILL REMAIN RATHER FRISKY THROUGH THE WEEKEND. WILL BE ENOUGH OF A NE SURGE TO SUPPORT 15-20 KT WINDS FOR A FAIRLY LONG DURATION. COULD BE EVEN STRONGER IF THE GRADIENT IS PINCHED FURTHER. THIS WILL BUILD SEAS INTO A MARGINAL SMALL CRAFT ADVISORY ON SATURDAY...AT LEAST IN THE NC WATERS AND PROBABLY NEAR CAPE ROMAIN AS WELL. THE MORE BLOCKED NEARSHORE WATERS OF LONG BAY WILL BE LIMITED TO 2-4 FT. && .ILM WATCHES/WARNINGS/ADVISORIES... SC...NONE. NC...NONE.
