The episode as NWS RAH wrote it up.
Numerous thunderstorms developed ahead of an approaching cold front in a very moist and marginally unstable environment. A few of the storms became severe, with one storm blowing down several large trees.
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 Raleigh, NC wrote its last area forecast discussion before the first event at Sep 10, 2:00 PM EST, 2 hours 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 300 PM EDT THU SEP 10 2015 .SYNOPSIS... A COLD FRONT WILL MOVE EAST THROUGH THE AREA OVERNIGHT. A WEAK AREA OF LOW PRESSURE WILL DEVELOP OVER THE CAROLINAS FRI AND FRI NIGHT...WHERE IT WILL LINGER UNTIL A STRONGER COLD FRONT MOVES EAST ACROSS THE REGION SAT AND SAT NIGHT. && .NEAR TERM /THROUGH TONIGHT/... AS OF 300 PM THURSDAY... A VERY MOIST AND UNSTABLE ATMOSPHERE (18Z MESO ANALYSIS INDICATES MODERATE INSTABILITY (3000 J/KG)OVER THE SANDHILLS AND COASTAL PLAIN) COUPLED WITH THE APPROACH/PASSAGE OF A VORTICITY SHEAR AXIS WILL TRIGGER SCATTERED CONVECTION ACROSS CENTRAL NC LATE THIS AFTERNOON...PERSISTING THROUGH MOST OF THE EVENING HOURS. DUE TO THE HIGH MOISTURE CONTENT OF THE ATMOSPHERE...TORRENTIAL DOWNPOURS WILL OCCUR WITH THE STRONGER STORMS. BULK OF WIND GUSTS WILL BE BELOW 35KTS THOUGH AN ISOLATED DAMAGING WIND GUSTS CANNOT BE RULED OUT. ANY PARTIAL CLEARING THAT OCCURS LATE THIS EVENING OR OVERNIGHT WILL QUICKLY FILL IN WITH LOW CLOUDS AND PATCHY FOG. MIN TEMPS IN THE UPPER 60S-LOWER 70S. && .SHORT TERM /FRIDAY AND FRIDAY NIGHT/... AS OF 300 PM THURSDAY... FRIDAY...VORTICITY SHEAR AXIS LIFT E-NE AWAY FROM OUR REGION. THIS FEATURE WILL LEAVE BEHIND A SURFACE TROUGH THAT SHOULD LIE ACROSS SECTIONS OF OUR COASTAL PLAIN AND SANDHILLS. MOISTURE POOLING ALONG THIS FEATURE AND AVAILABLE INSTABILITY SHOULD TRIGGER SCATTERED CONVECTION BY MID-LATE AFTERNOON. BASED ON EXPECTED POSITION OF THE SURFACE TROUGH...EXPECT HIGHEST THREAT FOR SCATTERED CONVECTION TO OCCUR ROUGHLY ALONG AND EAST OF A WADESBORO-SANFORD-TARBORO LINE. OVER MOST OF THE PIEDMONT...HARD TO DISCERN ANY FEATURE TO INITIATE CONVECTION ASIDE FROM STRONG DIURNAL HEATING. THUS WILL MAINTAIN SLIGHT CHANCE POPS OVER THIS REGION MAX TEMPS FRIDAY DEPENDENT UPON WHEN LOW STRATUS LIFTS/DISSIPATE OVER THE REGION. LATEST SREF GUIDANCE SUGGEST THAT LOW CLOUDS MAY LINGER OVER THE EASTERN COUNTIES THROUGH MOST OF THE MORNING WHILE PARTIAL SUN PROBABLE/LIKELY IN THE WEST PRIOR TO 15Z. CAVEAT...IF WESTERN PIEDMONT RECEIVES WIDESPREAD RAINFALL LATE THIS AFTERNOON/EVENING...THEN A SATURATED TOP SOIL MAY CAUSE LOW CLOUDS TO PERSIST LONGER HERE AS WELL. BASED ON THE SOLUTION OF PARTIAL SUNSHINE DELAYED IN THE EAST...EXPECT A FAIRLY UNIFORM TEMP FIELD IN THE MID-UPPER 80S. FRIDAY NIGHT...ISOLATED-SCATTERED CONVECTION SHOULD DIMINISH WITH LOSS OF HEATING THOUGH A STRAY SHOWER POSSIBLE ALMOST ANYWHERE OVERNIGHT. MIN TEMPS IN THE 65-70 DEGREE RANGE. && .LONG TERM /SATURDAY THROUGH THURSDAY/... AS OF 215 PM THURSDAY... SAT/SAT NIGHT: STILL LOOKS LIKE THE BEST CHANCE FOR NUMEROUS SHOWERS AND STORMS... PROMPTED BY THE PRESENCE OF THE OLD FRONTAL ZONE/TROUGH THROUGH CENTRAL NC... AND THE APPROACHING SYNOPTIC COLD FRONT EXPECTED TO MOVE THROUGH CENTRAL NC TO THE COASTAL PLAIN BY SUN MORNING. A BAND OF MID LEVEL SHEARED VORTICITY WILL STREAM NORTHEASTWARD FROM THE WRN GULF ACROSS THE FL PANHANDLE AND THROUGH ERN NC SAT... PROVIDING DYNAMIC FORCING FOR ASCENT ABOVE THE BEST LOW LEVEL MOISTURE... WHILE TO OUR WEST THE APPROACHING LONGWAVE TROUGH WILL GENERATE 60-80 M HEIGHT FALLS AND MID LEVEL LAPSE RATES APPROACHING 6.5 C/KM OVER THE REGION. WE SHOULD ALSO SEE STRONG UPPER DIVERGENCE IN THE RIGHT ENTRANCE REGION OF THE SHARPENING UPPER JET CORE... ADDING TO OVERALL ASCENT. THE 0-6 KM BULK SHEAR WILL BE STRENGTHENING TO 40-50 KTS... WITH MARGINAL TO MODERATE MUCAPE VALUES... AS MUCH AS 1000-1500 J/KG IN THE EASTERN CWA. HOWEVER... MODELS SUGGEST A LACK OF GOOD LOW LEVEL MOISTURE TRANSPORT OVER MUCH OF WRN/CENTRAL NC (CONFINED MOSTLY TO ERN NC)... DUE IN LARGE PART TO A NOTABLE WESTERLY COMPONENT TO THE LOW LEVEL WINDS AT 925/850 MB... AND MODELS SHOW JUST A NARROW BAND OF MODEST 700 MB MOISTURE MOVING THROUGH THE AREA LATE SAT AND PW VALUES BARELY AT OR JUST ABOVE NORMAL IN THE EAST ONLY. SO THIS ALL MAY SERVE TO LIMIT COVERAGE A BIT PARTICULARLY IN THE WEST... BUT A WELL- MIXED BOUNDARY LAYER COULD AUGMENT THE RISK OF DAMAGING DOWNBURST WINDS... AND THE INCREASED MID LEVEL FLOW ITSELF ORIENTED ROUGHLY PARALLEL TO THE SURFACE FRONT SHOULD HEIGHTEN THE THREAT OF ORGANIZED LINES AND BOWING SEGMENTS PROGRESSING QUICKLY ACROSS THE CWA DURING THE AFTERNOON INTO EVENING. WILL ADJUST POPS TO HAVE SLIGHT CHANCES IN THE MORNING... INCREASING IN COVERAGE TO NUMEROUS NW TO SE THROUGH THE AFTERNOON INTO EARLY EVENING... BEFORE TRENDING BACK DOWNWARD FROM WEST TO EAST OVERNIGHT AS THE FRONT AND DRIER AIR GRADUALLY SWEEP THROUGH. WILL KEEP A SLIGHT CHANCE IN THROUGH THE NIGHT HOWEVER WITH MODELS SHOWING LINGERING MOISTURE BELOW 8K FT AND A BRIEF RESURGENCE OF UPPER DIVERGENCE AS SPEED MAXIMA ROTATE INTO THE BASE OF THE UPPER TROUGH. THICKNESSES SUPPORT HIGHS FROM THE LOW 80S NW TO THE UPPER 80S SE. THICKNESSES DROP TO AROUND 15 M BELOW NORMAL BY SUN MORNING... SUGGESTING LOWS FROM THE UPPER 50S NW TO THE UPPER 60S SE... WHERE ANY BREAKS IN THE CLOUD COVER MAY NOT BE SEEN UNTIL AFTER SUNRISE. SUN/SUN NIGHT: A FEW SHOWERS MAY LINGER INTO THE MORNING HOURS SUN ACROSS THE SE CWA... BUT AS THE SURFACE FRONT CONTINUES ITS EASTWARD PROGRESSION... ALLOWING COOL SURFACE HIGH PRESSURE CENTERED OVER MO TO BEGIN TO BUILD IN FROM THE WEST... RAIN CHANCES WILL BE ON THE DECLINE AND SHOULD BE COMPLETELY GONE BEFORE NOON WITH THE ONSET OF STRONG SUBSIDENCE AND THE ARRIVAL OF SUB-1.0 INCH PW. EXPECT FLAT CU TO FILL IN BY AFTERNOON AS THE LONGWAVE TROUGH AXIS AND VORTICITY MAX SWING THROUGH... BUT OTHERWISE CLOUD COVER SHOULD BE DECREASING. EXPECT A SOMEWHAT BREEZY AND SEASONABLY COOL DAY... WITH THICKNESSES SUPPORTING HIGHS OF 72-79. LOWS IN THE 50S WITH WINDS DYING OFF AFTER SUNSET. MON-THU: HIGH CONFIDENCE IN DRY WEATHER AND PLENTY OF SUNSHINE DURING THIS PERIOD. THE SURFACE HIGH WILL SHIFT OVERHEAD THEN TO OUR NORTHEAST THROUGH THE WEEK... SETTLING OVER NEW ENGLAND BY THU WHILE EXTENDING DOWN THE EASTERN SEABOARD THROUGH CENTRAL NC. WE MAY SEE A AN INCREASE IN CLOUDS AREAWIDE THU AFTERNOON ALONG WITH A FEW SHALLOW SHOWERS IN THE EAST (ALONG/E OF I-95) WITH INCREASING ATLANTIC-SOURCE NE FLOW. THE MID LEVEL TROUGH AXIS LIFTS ENE AWAY FROM OUR AREA MON/TUE... WITH HEIGHTS CONTINUING TO RISE THROUGH MID- LATE WEEK AS ATLANTIC RIDGING SLIDES WESTWARD BENEATH THE EXITING TROUGH AND BUILDS OVER THE MIDATLANTIC AND SOUTHEAST... ENSURING CONTINUED DEEP LAYER SUBSIDENCE. THICKNESSES START OUT AT THEIR LOWEST MON MORNING (ABOUT 20 M BELOW NORMAL) THEN RISE INCREMENTALLY EACH DAY... BACK TOWARD NEAR-NORMAL VALUES BY THU... SO EXPECT HIGHS IN THE 70S TO NEAR 80 MON/TUE... INCHING UP TO 80-85 RANGE BY THU. MON AND TUE WILL BE OUR COOLEST MORNINGS WITH LOWS WELL DOWN INTO THE 50S... WITH SOME UPPER 40S IN OUTLYING AREAS IN THE PIEDMONT. LOWS WILL RECOVER BACK TO THE MID 50S TO AROUND 60 WED/THU MORNINGS. -GIH && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... AS OF 115 PM THURSDAY... A MOIST AND UNSTABLE AIR MASS ALONG WITH THE APPROACH AND PASSAGE OF A COUPLE OF SURFACE COLD FRONTS WILL RESULT IN PERIODS OF MVFR/IFR CEILINGS AND VISIBILITY DUE TO CONVECTION. THE CONVECTIVE THREAT APPEARS HIGHEST ACROSS CENTRAL NC BETWEEN 19Z-03Z...AND AGAIN FRIDAY AFTERNOON-EVENING THOUGH MAINLY ALONG AND EAST OF HIGHWAY 1. IN VICINITY OF THE STORMS...EXPECT WIND GUSTS 25-33KTS AND VISIBILITY AOB 1SM. LATER TONIGHT....AFTER 06Z...A LAYER OF LOW CLOUDS WILL DEVELOP RESULT IN CEILINGS AOB 1000FT. THESE LOW CEILINGS WILL LIKELY PERSIST WELL INTO FRIDAY MORNING...ESPECIALLY IN VICINITY OF KFAY AND KRWI. THE UNSETTLED WEATHER PATTERN WILL PERSIST INTO SATURDAY AS A WELL DEFINED COLD FRONT APPROACHES FROM THE NW...CROSSING CENTRAL NC SATURDAY NIGHT. A DRIER MORE STABLE AIR MASS AND ASSOCIATED VFR CONDITIONS WILL OVERSPREAD CENTRAL NC SUNDAY...LINGERING INTO EARLY NEXT WEEK. && .RAH WATCHES/WARNINGS/ADVISORIES...
