The episode as NWS RAH wrote it up.
Weak upper level disturbances moving within the weak cyclonic flow over the area combined with moist and unstable conditions to produce scattered afternoon/evening showers and thunderstorms. A couple of these storms resulted in some minor wind damage.

NWS Raleigh, NC wrote its last area forecast discussion before the first event at Jul 9, 1:57 PM EST, 37 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 257 PM EDT TUE JUL 9 2013 .SYNOPSIS... A WEAK UPPER LEVEL LOW PRESSURE TROUGH WILL HOLD OVER THE EASTERN U.S. THROUGH WEDNESDAY. A STRONGER UPPER LEVEL TROUGH AND ASSOCIATED SURFACE COLD FRONT WILL APPROACH THE AREA FROM THE NORTHEAST LATE WEDNESDAY... AND SWING THROUGH THE REGION THURSDAY THROUGH FRIDAY. && .NEAR TERM /THROUGH TONIGHT/... AS OF 230 PM TUESDAY... THROUGH TONIGHT: WATER VAPOR IMAGERY SHOWS A SUBTLE VORTICITY MAX DROPPING SOUTHEAST THROUGH CENTRAL... AND THIS FEATURE COMBINED WITH DAYTIME HEATING/DESTABILIZATION (MLCAPE OF 2000-2500 J/KG) AND ABUNDANT MOISTURE (PW VALUE HAVING REBOUNDED THIS AFTERNOON TO 1-8-2.0 IN.) HAVE LED TO SCATTERED STORMS... MORE NUMEROUS IN THE SOUTHEAST CWA AS DEPICTED WELL BY EARLIER FORECASTS AND RECENT HRRR MODEL RUNS. DEEP LAYER BULK SHEAR IS QUITE WEAK THOUGH WITH MARGINAL D-CAPE... SO ANY PARTICULARLY STRONG STORMS SHOULD REMAIN ISOLATED... BUT MIXED-PHASE CAPE AROUND 700 J/KG AND INCREASING MOISTURE IN THE -10C TO -30C LAYER ACCORDING TO RAP FORECAST SOUNDINGS SUGGESTS A THREAT OF SMALL HAIL WITH ANY STRONG CELL... AND CERTAINLY LOCALLY HEAVY DOWNPOURS REMAIN A CONCERN GIVEN THE SLOW MOVEMENT AND INCREASING PW. LOSS OF HEATING AS WELL AS THE PASSAGE OF THE WEAK WAVE EAST OF THE AREA SHOULD BRING A GRADUAL DISSIPATION OF CONVECTION BY CLOSE TO MIDNIGHT. FOLLOWING PERSISTENCE WITH NO SIGNIFICANT CHANGE IN AIR MASS... REDEVELOPMENT OF STRATUS IS ANTICIPATED ACROSS THE AREA LATE TONIGHT... WITH A LINGERING THREAT OF ISOLATED SHALLOW SHOWERS MAINLY IN THE SOUTH AND EAST WHERE ABUNDANT LOW LEVEL MOISTURE PERSISTS. LOWS CLOSE TO LAST NIGHT... 70-74. -GIH && .SHORT TERM /WEDNESDAY AND WEDNESDAY NIGHT/... AS OF 240 PM TUESDAY... FOR WEDNESDAY/WEDNESDAY NIGHT: LOOKS LIKE MORE OF THE SAME... WITH A CONTINUED HUMID AIR MASS AND MOIST COLUMN FEATURING PW VALUES OF 1.7-1.9 INCHES IN THE MORNING CLIMBING TO 1.9-2.1 INCHES IN THE AFTERNOON... HIGHEST EAST. WEAK LEE SURFACE TROUGHING HOLDS IN PLACE WITH A CONTINUATION OF LIGHT BREEZES FROM THE SW... WHILE IN THE MID LEVELS... VERY WEAK FLOW FROM THE WNW NEAR THE ILL-DEFINED SHEAR AXIS ALOFT WILL ALLOW FOR LITTLE TO NO DYNAMIC FORCING FOR ASCENT THROUGH THE AFTERNOON... ALTHOUGH THIS FLOW DOES INCREASE SLIGHTLY IN THE EVENING AND OVERNIGHT HOURS AS A STRONG WAVE DIGS INTO THE MEAN TROUGH OVER THE GREAT LAKES. MLCAPE ONCE AGAIN SHOULD TOP OUT AROUND 1500-2500 J/KG BUT WITH CONTINUED LOW DEEP-LAYER BULK SHEAR OF JUST 10-15 KTS... SO EXPECT ANOTHER ROUND OF SCATTERED STORMS WITH DESTABILIZATION... WITH HIGHEST POPS IN THE WRN CWA WHERE THE SREF INDICATES THE BEST CHANCE OF MEASURABLE RAIN... BUT ANY STORMS SHOULD HOLD BELOW SEVERE LIMITS. WILL RETAIN A MENTION OF ISOLATED SHOWERS OVERNIGHT WITH THE IMPROVING FLOW ALOFT AND LINGERING LOW LEVEL MOISTURE. HIGHS 86-90 AND LOWS AGAIN 70-74. -GIH && .LONG TERM /THURSDAY THROUGH TUESDAY/... AS OF 255 PM TUESDAY... THE OVERALL PATTERN FOR THE LONG TERM WILL BE DOMINATED BY A DEEPENING UPPER LEVEL TROUGH WITH ITS AXIS DIGGING TOWARDS THE EAST COAST. AT THE SURFACE COASTAL NORTH CAROLINA WILL BE SANDWICHED BETWEEN A STRENGTHENING SURFACE HIGH THAT WILL MOVE FROM THE GREAT PLAINS TO THE GREAT LAKES AND THE SLOWLY RETREATING BERMUDA HIGH IN THE SOUTHWESTERN ATLANTIC. IN BETWEEN A SURFACE LOW MOVING ACROSS CENTRAL ONTARIO AND QUEBEC WILL SET UP A FRONTAL ZONE THAT WILL EXTEND DOWN THE EASTERN SEABOARD...EVENTUALLY STALL OUT AND THEN POTENTIALLY RETROGRADE NEAR THE END OF THE PERIOD. TOWARDS THE END OF THE PERIOD THE X FACTOR WILL BE THE DEVELOPMENT AND TRACK OF TROPICAL STORM CHANTAL. THURSDAY AND FRIDAY: STARTING ON THURSDAY THE FRONTAL ZONE WILL BE DRAPED ACROSS THE WESTERN PIEDMONT WHICH IS WHERE THE HIGHEST PRECIPITATION CHANCES WILL BE. WITH PW VALUES IN EXCESS OF 2 INCHES. CONVECTION FEATURING HEAVY RAIN IS PROBABLE WITH THE LEE TROUGH AND DIFFERENTIAL HEATING BOUNDARIES THE MAIN FOCI FOR CONVECTION. WILL KEEP HIGHEST POPS IN THE NW THURSDAY AFTERNOON BUT OVERSPREADING THE ENTIRE CWA BY THURSDAY NIGHT. BY FRIDAY MORNING THE FOCUS FOR CONVECTION WILL SHIFT FURTHER EAST AS THE SURFACE HIGH OVER THE GREAT LAKES BUILDS INTO THE 1020S AND THE BERMUDA HIGH WEAKENS SLIGHTLY. ONCE REACHING THE COASTAL PLAIN THE FRONT WILL SLOW AND BECOME STAGNANT KEEPING THE BEST CHANCE FOR RAIN IN THE SOUTHEAST ON FRIDAY WHERE PW VALUES WILL REMAIN ABOVE 2 INCHES. BACK TOWARDS THE TRIANGLE PWS WILL DROP TO ABOUT 1.5 INCHES AND COVERAGE AND INTENSITY OF PRECIPITATION SHOULD WANE. QPF WILL BE TRICKY ONCE AGAIN AS CONVECTION WILL BE LOCALLY HEAVIER. FOR NOW WILL GO WITH ABOUT AN INCH FOR THESE TWO DAYS COMBINED WITH SOME LOCALES POTENTIALLY SEEING 2-3 INCHES IN HEAVIER AND TRAINING STORMS. STORM TOTAL QPF SHOULD BE GREATER IN THE SOUTHEAST AND DECREASING BACK TOWARDS THE TRIAD. MAX TEMPERATURES THESE TWO DAYS WILL BE IN THE MID TO UPPER 80S WITH LOWS IN THE LOWER 70S AND POTENTIALLY SOME UPPER 60S IN THE NORTHWEST ON FRIDAY NIGHT INTO SATURDAY MORNING AS THE FRONT PUSHES EASTWARD. DEWPOINTS WILL BE DEPENDENT UPON LOCATION WITH LOWER 70S COMMON AHEAD OF THE FRONT AND UPPER 60S BEHIND IT. SATURDAY AND SUNDAY: THE HIGH TO THE NORTH WILL CONTINUE TO STRENGTHEN KEEPING THE FRONTAL ZONE RESTRICTED TO THE COAST AS A CUT OFF MESO LOW OFF OF THE NEW ENGLAND COAST WILL TAKE OVER FOR THE PARENT LOW AND CONTINUE QUICKLY OFF TO THE NORTHEAST. THIS WILL BEGIN TO WASH OUT THE FRONT A LITTLE. IN ADDITION THE HIGH WILL BUILD DOWN FROM THE NORTH CAUSING THE FRONTAL ZONE TO TAKE A MORE WEST TO EAST ORIENTATION. BEST CHANCES FOR PRECIP WILL BE IN THE SOUTH AND EAST WITH DRIER CONDITIONS TO THE NW. ON SUNDAY WHATS LEFT OF THE FRONT WILL START TO RETROGRADE BACK OVER THE CWA WITH NEW MOISTURE TRANSPORT REINFORCEMENTS FROM TROPICAL STORM CHANTAL OR WHATEVER THE REMNANTS MAY BE AT THAT TIME. PW VALUES WILL ONCE AGAIN APPROACH 2 INCHES IN THE SOUTHERN HALF OF THE CWA. HIGHS ONCE AGAIN IN THE MID TO UPPER 80S WITH LOWS UPPER 60S TO LOW 70S. MONDAY AND TUESDAY: THIS PERIOD REMAINS LOW CONFIDENCE BECAUSE OF THE UNCERTAINTY IN THE LOCATION AND STRENGTH OF CHANTAL AT THIS TIME. THE BERMUDA HIGH WILL BEGIN TO MOVE BACK WESTWARD WHICH WILL HELP TO FUNNEL MOISTURE IN FROM THE ATLANTIC. WILL KEEP CHANCE POPS THROUGH THE PERIOD WITH HIGHEST CHANCES IN THE SOUTHEAST. TEMPS WILL REMAIN MID TO UPPER 80S AND LOWS UPPER 60S TO LOW 70S. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... AS OF 1245 PM TUESDAY... MVFR CIGS WILL CONTINUE TO COME AND GO AT CENTRAL NC TAF SITES THROUGH 20Z AS CLOUDS BASED AT 1-3 THOUSAND FT WILL VARY BETWEEN SCATTERED AND BROKEN. EXPECT VFR CIGS AFTER 20Z. NUMEROUS SHOWERS AND STORMS ARE EXPECTED BETWEEN 20Z AND 03Z WITH BEST COVERAGE NEAR FAY/RWI... FEWER SHOWERS/STORMS AT RDU AND EVEN FEWER (SCATTERED AT MOST) AT INT/GSO. IN/NEAR THESE STORMS... MVFR/IFR CIGS/VSBYS AND BRIEF WIND GUSTS OVER 30 MPH ARE POSSIBLE. OTHERWISE... VFR CONDITIONS AND LIGHT WINDS FROM THE SOUTH OR SW (UNDER 12 KTS) WILL DOMINATE UNTIL AROUND 07Z... WHEN IFR STRATUS IS EXPECTED TO DEVELOP ONCE AGAIN... AS HAS OCCURRED ON PREVIOUS MORNINGS. CIGS SHOULD LIFT SLOWLY TO MVFR BY 16Z-18Z. LOOKING BEYOND 18Z WEDNESDAY... CIGS ARE EXPECTED TO TREND TO VFR 18Z-20Z WEDNESDAY WITH SCATTERED STORMS DEVELOPING. IFR CONDITIONS ARE LIKELY TO RETURN AFTER 07Z THURSDAY THROUGH MID MORNING... LIFTING SLOWLY TO MVFR THEN VFR BY EARLY THURSDAY AFTERNOON. OCCASIONALLY MVFR CONDITIONS ARE LIKELY WITH NUMEROUS SHOWERS AND STORMS THURSDAY AFTERNOON THROUGH FRIDAY. MVFR CONDITIONS COULD LINGER AT FAY THROUGH SUNDAY... BUT OTHERWISE VFR CONDITIONS ARE EXPECTED TO DOMINATE FRIDAY NIGHT THROUGH SUNDAY... ALTHOUGH IFR STRATUS IS AGAIN LIKELY 07Z-14Z SUNDAY MORNING. -GIH && .RAH WATCHES/WARNINGS/ADVISORIES...
