The episode as NWS RAH wrote it up.
Band of strong to severe thunderstorms ahead of an upper level trough and trailing surface cold front, moved into central North Carolina during the early afternoon hours. |The storms produced scattered thunderstorm wind damage with the the greatest concentration of tree damage reported in the Triad. Localized heavy rainfall of 2 to 2.5 inches also resulted in flash flooding in Greensboro.

NWS Raleigh, NC wrote its last area forecast discussion before the first event at Jun 22, 12:45 PM EST, 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 145 PM EDT FRI JUN 22 2012 .SYNOPSIS... A COLD FRONT WILL MOVE INTO OUR REGION FROM THE NORTHWEST THIS EVENING AND TONIGHT... THEN STALL OVER SOUTHERN AND EASTERN NORTH CAROLINA ON SATURDAY. && .NEAR TERM /THROUGH TONIGHT/... AS OF 1015 AM FRIDAY... A COUPLE SHOWERS THAT DEVELOPED JUST AFTER SUNRISE THIS MORNING HAVE REMAINED TO THE SOUTH OF FAYETTEVILLE AND CLINTON AND ALL OF CENTRAL NC IS FREE OF CONVECTION. THE SHALLOW UPPER LEVEL DISTURBANCE NOTED IN THE PREVIOUS DISCUSSIONS SHOWS UP WELL IN THE LATEST WATER VAPOR IMAGES AND THE CENTER OF THE CIRCULATION IS CURRENTLY APPROACHING THE NC/SC BORDER OVER THE SOUTHERN PIEDMONT. THE WEAK COLD FRONT APPROACHING FROM THE WEST STRETCHED FROM CENTRAL WV TO JUST WEST OF KNOXVILLE AS OF 12Z. CHANGES TO THE POP FORECAST WILL BE MINOR THIS MORNING...MAINLY TO INCLUDE CHANCE WORDING EVERYWHERE BY 18Z AS THE AFOREMENTIONED UPPER WAVE DRIFTS NORTH ACROSS A MOSTLY UNINHIBITED AND INCREASINGLY UNSTABLE AIRMASS. MOST HI-RES GUIDANCE SUGGESTS STORMS WILL BE MOST LIKELY OVER THE NORTHERN COASTAL PLAIN LATE THIS AFTERNOON AND EVENING....ONCE STORMS DEVELOPING ALONG THE HIGHER TERRAIN AND PREFRONTAL TROUGH PROGRESS EASTWARD. THIS AREA ALSO CONTINUES TO BE MOST FAVORED FOR ANY WEAK ORGANIZATION OF STORM CLUSTERS WHERE DEEP LAYER SHEAR MAY APPROACH 25KT AND OVERLAP WITH 1000-1500 J/KG MLCAPE. THE MAIN THREAT FROM STORMS WILL BE DAMAGING MICROBURSTS WITH STEEPENING LOW LEVEL LAPSE RATES AND LCLS APPROACHING 5-6K FT. WEAK MID LEVEL FLOW WILL ALSO BRING A RISK OF SLOW MOVING STORMS AND LOCALIZED FLOODING. CONCERNING HIGHS TODAY....THE 1000-850MB THICKNESS ON THE 12Z RAOB AT KGSO WAS 1420M...IDENTICAL TO THURSDAY MORNING. WITH NO CHANGE IN AIRMASS AND AN 850MB TEMP OF 19C WHICH IS ALSO THE SAME AS THURSDAY...HAVE ELECTED TO NUDGE HIGHS UP A COUPLE DEGREES EAST OF THE TRIAD... CLOSER TO THURSDAYS VALUES. THIS IS MOSTLY INLINE WITH MAV MOS GUIDANCE AND YIELDS 92-96. -SMITH TONIGHT: FOCUS FOR SHOWERS AND THUNDERSTORMS WILL SHIFT MORE TO THE EAST/SOUTHEAST BY LATE EVENING/OVERNIGHT TONIGHT... AS THE PRE-FRONTAL TROUGH SLOWLY SHIFTS IN THAT DIRECTIONS... ALONG WITH THE MAIN MID LEVEL TROUGH AXIS BEGINNING TO SHIFT ACROSS THE REGION. THE ACTUAL FRONT AT THIS TIME BECOMES DIFFUSE AND HARD TO DEFINED... WITH THE DRIER AIR ALOFT BECOMING THE MORE SIGNIFICANT FEATURE TO ENDING PRECIP CHANCES ACROSS THE NORTHWESTERN HALF OF THE CWA OVERNIGHT... WITH THE PRE-FRONTAL TROUGH/NEW COLD FRONT (IF YOU WANT TO CALL IT THAT... NOT MUCH IF ANY LOW LEVEL AIRMASS CHANGE) BECOMING THE MAIN FOCUS FOR PRECIP. THUS... WILL GENERALLY END POPS ACROSS THE NORTHWESTERN HALF OF THE CWA AFTER MIDNIGHT AND REDUCE POPS TO SLIGHT CHANCE/ISOLATED FOR THE REST OF THE CWA. EXPECT WARM LOW TEMPS AGAIN... WITH LOW TEMPS SATURDAY MORNING GENERALLY IN THE LOWER 70S. && .SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/... AS OF 3 AM FRIDAY... LINGERING SURFACE BOUNDARY/TROUGH ACROSS THE AREA MAY AGAIN BE THE FOCUS FOR AFTERNOON SHOWERS AND THUNDERSTORMS ON SATURDAY AFTERNOON... ALONG WITH SOME HELP FROM AN UPPER LEVEL DISTURBANCE MOVING THROUGH THE SLOWLY DEPARTING MID/UPPER TROUGH ALOFT. HOWEVER... QUESTION REMAIN ON HOW QUICKLY THIS BOUNDARY WILL BEGIN TO PUSH TO THE SOUTH AND EAST OF THE AREA ALONG WITH HOW MUCH ADDED HELP THE UPPER LEVEL ENERGY WILL PROVIDE. THE GFS IS A MORE EXCITED ABOUT SHOWER AND THUNDERSTORM DEVELOPMENT ACROSS A LARGE PORTION OF OUR AREA. IT DEVELOPS SCATTERED SHOWERS AND STORMS ACROSS MOST OF THE AREA ON SATURDAY AFTERNOON... WITH THE NAM AND THE ECMWF SHOWING MOST OF THE SHOWERS/STORMS ACROSS SOUTHERN AND EASTERN PORTIONS OF THE AREA. FOR NOW WILL CONTINUE TO SHOW THE TREND OF NO POP/SLIGHT CHANCE POPS NW TO CHANCE SOUTH AND EAST. GIVEN EXPECTED INSTABILITY INVOF AND TO THE SOUTH OF THE SURFACE BOUNDARY IN THE 1500 TO 2500 J/G RANGE... WITH NORTHERLY DEEP LAYER SHEAR A BIT STRONGER THAN TODAY... EXPECT WE CLOUD SEE AT LEAST A FEW STRONG TO PERHAPS SEVERE STORMS... AND AGAIN MAINLY ACROSS THE SOUTH/SOUTHEAST... WITH DAMAGING DOWNBURST WINDS AND LOCALIZED FLOODING THE MAIN THREAT. WILL MAKE A BRIEF MENTION IN THE HWO ABOUT THE THIS THREAT. EXPECT HIGH TEMPS ON SATURDAY TO BE GENERALLY AROUND 90 DEGREES. ANY SHOWERS AND STORMS ARE EXPECTED TO DISSIPATE/DECREASE SIGNIFICANTLY IN COVERAGE BY MID TO LATE EVENING... WITH POSSIBLY SOME LINGERING CHANCES FOR SHOWERS ACROSS THE FAR SOUTH/SOUTHEASTERN PORTIONS OF THE AREA FOR THE ENTIRE NIGHT... NEAR THE SURFACE BOUNDARY. THUS... WILL END CHANCES FOR SHOWERS/STORMS BY MIDNIGHT... EXPECT ACROSS THE SOUTH/SOUTHEAST... WITH CONTINUING SLIGHT CHANCE OF SHOWERS THERE. EXPECT OVERNIGHT LOWS TO BE IN THE UPPER 60S NORTH TO LOWER 70S SOUTH. && .LONG TERM /SUNDAY THROUGH THURSDAY/... AS OF 250 AM FRIDAY... OVERALL...THIS PERIOD WILL BE DOMINATED BY A DEEPENING UPPER LEVEL TROUGH OVER THE EAST COAST...WHILE A STRONG UPPER LEVEL RIDGE DEVELOPS OVER THE CENTRAL PLAINS. AN UPPER LOW IS PROGGED TO DROP SOUTHEASTWARD INTO NEW ENGLAND LATE SUNDAY INTO MONDAY...ALTHOUGH AS CAN BE EXPECTED MODELS CONTINUE TO DIFFER WITH RESPECT TO THE STRENGTH AND EXACT POSITION OF ITS CENTER. NEVERTHELESS...AM EXPECTING MINIMAL PRECIP CHANCES ON SUNDAY (MAINLY DIURNAL CONVECTION) AS MOISTURE WILL BE LIMITED AND FORCING WILL MAINLY BE DEPENDENT ON ANY WEAK DISTURBANCES MOVING ACROSS THE AREA IN THE NORTHWESTERLY FLOW ALOFT. THE BEST SHOT FOR PRECIP STILL LOOKS TO BE MONDAY INTO TUESDAY AS A SHORTWAVE TROUGH PROPELS A STRONGER FRONT THROUGH THE REGION. HOWEVER...THERE IS QUITE A BIT OF UNCERTAINTY WITH HOW FAR SOUTH THIS FRONT WILL MAKE IT...AS IT HINGES ON WHERE THE LOW ACROSS THE GULF OF MEXICO ULTIMATELY TRACKS. MODELS HAVE BEEN ALL OF THE PLACE THE PAST SEVERAL RUNS WITH RESPECT TO THIS LOW...THEREFORE CONFIDENCE IS LOW. AS A RESULT...WILL MAINTAIN FORECAST CONTINUITY WHICH WOULD ALLOW THE FRONT TO PROGRESS THROUGH THE REGION...LEADING TO NO MORE THAN SLIGHT CHANCE (MAINLY AFTERNOON/EVENING AND ACROSS THE SOUTHEAST HALF OF THE FORECAST AREA) CONVECTION BEYOND TUESDAY. TEMPS ARE EXPECTED TO RUN NEAR TO SLIGHTLY ABOVE NORMAL THROUGH AT LEAST THE BEGINNING OF NEXT WEEK...WITH HIGHS GENERALLY IN THE LOW 90S. BY TUESDAY AND THEN FOR THE REMAINDER OF THE FORECAST PERIOD... HIGH TEMPS ARE EXPECTED TO FALL INTO THE MID/UPPER 80S (MAYBE EVEN SOME LOWER 80S) AS THE UPPER TROUGH DEEPENS OVER THE EASTERN SEABOARD. MUGGY NIGHTS WILL CONTINUE...WITH OVERNIGHT LOWS GENERALLY IN THE UPPER 60S TO NEAR 70 DEGREES...WITH MAYBE A SLIGHT BREAK TOWARDS THE MIDDLE OF NEXT WEEK WHEN SOME LOW TO MID 60S MAY FILTER INTO THE NORTH. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... AS OF 145 PM FRIDAY... SCATTERED STORMS ARE BEGINNING TO FORM OVER THE HIGHER TERRAIN OF NC AND SOUTHWEST VA AND WILL CONTINUE TO DRIFT EAST INTO THE PIEDMONT THIS AFTERNOON....AFFECTING KGSO/KINT BY 19Z AND KRDU BY 20-21Z. MORE ISOLATED SHOWERS AND STORMS ARE POSSIBLE FROM KFAY TO KRWI THIS AFTERNOON...AND IT IS POSSIBLE THAT THE STORMS OVER WESTERN NC MAY PUSH ALL THE WAY EAST INTO THE COASTAL PLAIN THIS EVENING. THUS...WHILE IMPACTS AT INDIVIDUAL TERMINALS ARE UNCERTAIN...MOST TERMINALS ACROSS CENTRAL NC RUN A 30-40 PERCENT CHANCE OF BEING IMPACTED BY A STORM. COVERAGE OF STORMS WILL DECREASE AFTER SUNSET THIS EVENING...BUT A COLD FRONT APPROACHING FROM THE WEST WILL SLOWLY SINK THROUGH CENTRAL NC OVERNIGHT...AND MAY BE THE CATALYST FOR A FEW SHOWERS OR STORMS OVERNIGHT. DEWPOINTS ARE NOT EXPECTED TO FALL DRAMATICALLY BEHIND THE FRONT...AND DEPENDING ON WHERE STORMS OCCUR THIS EVENING...ISOLATED POCKETS OF FOG MAY BE A PROBLEM. ISOLATED TO WIDELY SCATTERED SHOWERS AND STORMS WILL BE POSSIBLE ONCE AGAIN ON SATURDAY...MAINLY SOUTH AND EAST OF KRDU AND AFTER 18Z. OUTLOOK... VFR CONDITIONS ARE EXPECTED TO BE PREDOMINATE THROUGH EARLY NEXT WEEK...WITH ISOLATED AFTERNOON AND EVENING SHOWERS/STORMS AND EARLY MORNING SUB-VFR VSBYS POSSIBLE THROUGH MONDAY. && .RAH WATCHES/WARNINGS/ADVISORIES...
