The episode as NWS RAH wrote it up.
Severe thunderstorms developed across the Northwest Piedmont during the evening hours as a strong mid-level shortwave trough moved across the Appalachians and across the area. The severe thunderstorm wind damage was confined to the Triad.|Lightning associated with the convection was excessive with over 600 cloud-to-ground lightning strikes per hour. Two structures were hit by lightning, with one of the structures being completely destroyed as fire consumed the mobile home.

NWS Raleigh, NC wrote its last area forecast discussion before the first event at Jun 10, 2:00 PM EST, 4 hours 51 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 300 PM EDT WED JUN 10 2009 .SYNOPSIS... A VERY MOIST AND UNSTABLE AIR MASS WILL REMAIN IN PLACE THROUGH LATE IN THE WEEK. AHEAD OF A WEAKENING COLD FRONT MOVING INTO THE REGION TOWARD THE WEEKEND...PASSING DISTURBANCES IN A PROGRESSIVE... WESTERLY FLOW ALOFT WILL BRING UNSETTLED WEATHER. TEMPERATURES WILL REMAIN AT OR ABOVE NORMAL. && .NEAR TERM /THROUGH TONIGHT/... AS OF 340 PM WEDNESDAY... MSAS SHOWS AMPLE SURFACE DIVERGENCE ACROSS CENTRAL NORTH CAROLINA... BUT INSTABILITY WAS INCREASING TOWARD THE MOUNTAINS WITH VALUES APPROACHING -6C. MSAS WAS ALSO SHOWING DEW POINT ADVECTION ACROSS SOUTH CAROLINA TOWARD THE SOUTHWEST PIEDMONT...WHICH SHOULD HELP TO INCREASE INSTABILITY FURTHER. WHILE IT IS ALWAYS DIFFICULT TO DETERMINE THE EXACT EVOLUTION OF CONVECTIVE SYSTEMS...PARTICULARLY CONSIDERING HOW UPSTREAM ACTIVITY WILL INFLUENCE DEVELOPMENT ALONG AND EAST OF THE MOUNTAINS...THE PREPONDERANCE OF THE EVIDENCE SUGGESTS THAT SCATTERED-TO-NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP ALONG AND EAST OF THE MOUNTAINS LATE THIS AFTERNOON AHEAD OF A SHORTWAVE MOVING EAST ACROSS KENTUCKY AND TENNESSEE...AND IN WEAKLY DIVERGENT UPPER FLOW ACROSS NORTH CAROLINA. SPC AND LOCAL WRF BOTH SUGGEST LATE AFTERNOON AND EVENING ACTIVITY MAKING IT TO AT LEAST AROUND U.S. 1 BEFORE LESSER INSTABILITY AND MOISTURE MAY CAUSE SOME WANING OF ANY SHOWERS AND THUNDERSTORMS AS THEY APPROACH THE COASTAL PLAIN. BOTH THE GFS AND THE NAM...WHILE INCREASING PRECIPITABLE WATER VALUES TO NEAR TWO INCHES...HAVE ON THEIR BUFR SOUNDINGS A DECENT INCREASE IN MOISTURE AND INSTABILITY BETWEEN 21Z AND 03Z ESPECIALLY WEST OF KRWI. BOTH THE GFS AND THE NAM PROVIDE FOR AMPLE MID-LEVEL MOISTURE THROUGHOUT THE NIGHT...WHICH SHOULD RESULT IN MOSTLY CLOUDY SKIES. OVERNIGHT LOWS ARE EXPECTED TO BE WITHIN A DEGREE OR THREE OF 70. BASED ON THE EXPECTED AMOUNT OF CLOUD COVER...WILL KEEP THE MENTION OF FOG OUT OF THIS FORECAST. && .SHORT TERM /THURSDAY THROUGH SATURDAY NIGHT/... AS OF 240 PM WEDNESDAY... INSTABILITY IS FORECAST TO BE GREATER ACROSS CENTRAL NORTH CAROLINA THURSDAY...WITH MUCAPE AOA 2000J/KG DURING THE MID AFTERNOON. MODEL SOUNDINGS ARE UNSTABLE AS WELL...AND WITH ANOTHER MID-LEVEL WAVE MOVING ACROSS CENTRAL NORTH CAROLINA THURSDAY AFTERNOON...ANTICIPATE SCATTERED-TO-NUMEROUS SHOWERS AND THUNDERSTORMS ONCE AGAIN WITH INITIATION ALMOST CERTAINLY EARLIER THAN TODAY. WILL CONTINUE WITH THE LIKELY CHANCES THROUGHOUT CENTRAL NORTH CAROLINA FOCUSED ON THE AFTERNOON...AND WHILE WILL NOT TRY TO FINE TUNE POPS FOR THIS FORECAST IN THE CURRENT WEATHER REGIME...THE BETTER CHANCES MAY END UP JUST EAST OF THE FAR WESTERN PIEDMONT TOWARD U.S. 1 AND EAST...WHERE GUIDANCE SUPPORTS THE AXIS OF BROAD LIFT AND MID-LEVEL PVA. DESPITE AT LEAST A FEW PEEKS OF SUN...GIVEN THE OVERALL EXPECTED CLOUD COVER AND MOISTURE HIGHS SHOULD BE FROM 85 TO AROUND 90 DEGREES. SOUTH OF THE RIGHT ENTRANCE REGION OF A 65KT 250MB JET THAT IS LOCATED JUST NORTH OF CENTRAL NORTH CAROLINA THURSDAY EVENING... AND ASSOCIATED WITH ANOTHER MID-LEVEL WAVE IN THE PERSISTENT WESTERLY FLOW...CHANCES FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE THURSDAY NIGHT INTO THE OVERNIGHT HOURS. MODEL SOUNDINGS BECOME MORE STABLE OVERNIGHT IN CONJUNCTION WITH A PERIOD OF UPPER-LEVEL CONVERGENCE AND WITH THE PASSAGE OF THE JET TO THE NORTHEAST...SO CHANCES FOR SHOWERS WILL ONCE AGAIN BE LOWERED FOR THE LATE NIGHT HOURS. OVERNIGHT LOWS WILL AGAIN BE FORECAST AROUND 70. A VERY BROAD/NEARLY FLAT UPPER LEVEL TROUGH ACROSS THE EASTERN US WILL ALLOW A COLD FRONT TO SLIP SOUTH ACROSS THE VIRGINIAS ON FRIDAY AND FRIDAY NIGHT. NWP GUIDANCE DIFFERS IN THE HANDLING OF THIS FEATURE...NO SURPRISE GIVEN THE ABSENCE OF LARGE SCALE FORCING. A WEAK SFC LOW MAY DEVELOP ALONG THE FRONT WHICH CLOUD LEAD TO ENHANCED PRECIP. GREATEST THREAT OF ORGANIZED SVR WILL BE NEAR THE VA BORDER WHERE SHEAR IS THE STRONGEST PROVIDED ENOUGH INSTABILITY IS PRESENT. EVEN WITH DECENT CLOUD COVER...SW FLOW WILL ALLOW HIGH TEMPS ON FRIDAY TO REACH THE MID 80S TO NEAR 90. THE FRONT STALLS ACROSS THE COASTAL PLAIN AND COASTAL REGION ON SATURDAY BEFORE SLIPPING FURTHER SOUTH SATURDAY NIGHT. WEAK PERTURBATIONS IN THE W FLOW WILL ENHANCE OR INITIATE CONVECTION. THIS WILL FOCUS CONVECTION ACROSS THE E PARTS OF CWA AND WE HAVE ADJUSTED POPS ACCORDINGLY. LOW TEMPS SAT MORNING WILL RANGE IN THE MID 60S TO NEAR 70. HIGHS ON SAT WILL RANGE IN THE MID TO UPPER 80S. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... AS OF 240 PM WEDNESDAY... UPPER LEVEL PATTERN FOR THE BEGINNING OF THE EXTENDED RANGE FEATURES A FAIRLY DEEP TROUGH OVER THE WEST COAST...A MODEST RIDGE AXIS EXTENDING NORTH OVER THE CENTRAL PLAINS AND A GENERALLY FLAT W FLOW ACROSS THE MID ATLANTIC. THE RIDGE OVER THE CENTRAL US AMPLIFIES DURING THE EXTENDED RANGE BUILDING TO A 592M HIGH CENTER OVER E TX/LA WITH A RIDGE EXTENDING INTO THE CENTRAL GREAT LAKES. THIS ALLOWS AN EASTERN CONUS TROUGH TO AMPLIFY AND THE UPPER FLOW OVER THE MID ATLANTIC TO BECOME NW LEADING TO DRIER CONDITIONS AND BELOW NORMAL TEMPS. SHORT WAVE ENERGY OVER E CANADA DRIVES SOUTH ACROSS THE GREAT LAKES LATE ON SUN. THE FRONT ACROSS SC/GA SHOULD LIFT NORTH SUN AND SUN NIGHT AS A DEVELOPING AREA OF LOW PRESSURE MOVES ACROSS THE OH VALLEY AND THE MID ATLANTIC. THIS WILL RESULT IN CONSIDERABLE CLOUDINESS WITH SCT CONVECTION. THE GREATEST CHC OF CONVECTION WILL BE ON SUN AFTN AND EVE WITH POPS CONFINED IN THE LOW CHC RANGE UNTIL THE TIMING BECOMES MORE DEFINITIVE. AS THE SHORTWAVE TROUGH SWEEPS ACROSS THE OH VALLEY...AN ASSOCIATED COLD FRONT WILL MOVE ACROSS THE CAROLINAS AND VIRGINIA ON MONDAY BRINGING ANOTHER FOCUS FOR THUNDERSTORMS. THERE COULD BE ENOUGH SHEAR TO SUPPORT SOME ORGANIZED SEVERE WEATHER AS BULK SHEAR VALUES FROM THE GFS RANGE AROUND 30 KTS NEAR THE VA BORDER AND UP TO 50 KTS OR MORE ACROSS CENTRAL OR NORTHERN VA. EXPECT A PERIOD OF MORE SETTLED WEATHER WITH COOLER TEMPS AND DRIER CONDITIONS ON TUESDAY AND WEDNESDAY AS THE COLD FRONT DEPARTS AND A NW FLOW DOMINATES. NO REAL CONFIDENCE IN THE 10/00Z ECMWF DEPICTION OF A DEEP CUTOFF LOW OFF THE NJ COAST BUT A NW FLOW SEEMS A GOOD BET. TEMPS WILL LIKELY BE NEAR NORMAL TO A FEW DEGREES BELOW NORMAL WITH A PRETTY GOOD DIURNAL RANGE IN TEMPS WITH A DRIER AIRMASS. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... AS OF 145 PM WEDNESDAY... IN A CONTINUED MOIST AND UNSTABLE AIR MASS...WITH WEAK MID-LEVEL DISTURBANCES AND A SURFACE TROUGH NEARBY OR OVERHEAD...CONTINUED SCATTERED-TO-NUMEROUS SHOWERS AND THUNDERSTORMS WILL REMAIN... WITH THE MOST COVERAGE DURING THE AFTERNOON AND EVENING HOURS. TONIGHT...EXPECT A GRADUAL INCREASE IN THUNDERSTORMS OVER AND EAST OF THE MOUNTAINS WITH NUMEROUS SHOWERS AND THUNDERSTORMS ESPECIALLY WEST OF KRWI. OUTSIDE OF THUNDERSTORMS...CONDITIONS WILL MAINLY BE VFR WITH ISOLATED AREAS OF LOW MVFR OR HIGH IFR IN LOW CLOUDS. WITH THE AIR BEING MORE UNSTABLE THURSDAY...INITIATION OF SCATTERED- TO-NUMEROUS SHOWERS AND THUNDERSTORMS SHOULD BE EARLIER. THE DEEPER CONVECTION SHOULD AGAIN LAST INTO THE EVENING BEFORE BECOMING MORE ISOLATED OR DISSIPATING LATE. A WEAKENING FRONT MOVES INTO CENTRAL NORTH CAROLINA LATE IN THE WEEK...BUT EXPECT DIURNAL...AT LEAST SCATTERED SHOWERS AND THUNDERSTORMS FRIDAY BEFORE SUCH CONDITIONS ARE EXPECTED TO BECOME SOMEWHAT MORE ISOLATED WITH A BETTER CHANCE FOR SCATTERED...DEEP CONVECTION FARTHER SOUTH AND EAST INTO THE WEEKEND. ANOTHER FRONT MAY APPROACH FROM THE NORTH MONDAY. IN THE MOIST AIR MASS...LATE NIGHT AND EARLY MORNING LOW CLOUDS CERTAINLY REMAIN A FACTOR. && .RAH WATCHES/WARNINGS/ADVISORIES...
