The episode as NWS RAH wrote it up.
Scattered showers and thunderstorms developed across the region as an upper level trough and associated surface cold front approached the area from the northwest. Strong heating and high moisture content resulted in a moderately unstable air mass and with the increased low level forcing, as well as increasing upper level dynamics, several of the storms became strong to severe, producing some isolated wind damage. Also, frequent lightning also resulted in a couple of fires, one which completely destroyed a home.
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 Jul 20, 2:02 PM EST, 2 hours 23 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 302 PM EDT FRI JUL 20 2012 .SYNOPSIS... A COLD FRONT APPROACHING FROM THE NORTH WILL STALL OVER THE AREA THROUGH THE WEEKEND...PROVIDING FOR UNSETTLED WEATHER. AS THE FRONT BASICALLY DISSIPATES BY EARLY NEXT WEEK...HIGH TEMPERATURES ONCE AGAIN WILL WARM TO LEVELS ABOVE NORMAL. && .NEAR TERM /THROUGH TONIGHT/... AS OF 300 PM FRIDAY... SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS DEVELOPED EARLY THIS AFTERNOON IN A REGIME WHERE THE MLCAPE WAS APPROACHING 2000J/KG ON THE LATEST SPC MESOANALYSIS...AND APPARENTLY NEAR A SHEAR AXIS ALOFT ON WATER VAPOR IMAGERY. THIS SHEAR AXIS WAS NOTED WEAKLY ON THE 700MB 12Z UPPER-AIR ANALYSIS...THOUGH ORIENTED AT THAT TIME WEAKLY WEST TO EAST. EVENING CHALLENGE IS HOW THIS DEEP CONVECTION WILL INFLUENCE...IF ANY...AN UPSTREAM SHORTWAVE MOVING EAST. LATER HRRR WRF GUIDANCE SUGGESTS A REMNANT MCV MOVING FROM UPSTREAM ACROSS AREAS FARTHER SOUTH THAN EARLIER RUNS...CLOSER TO THE SOUTH CAROLINA BORDER AS OPPOSED TO NEARER THE VIRGINIA BORDER AND THE NORTHWEST PIEDMONT. THE LATEST SPC MESOANALYSIS WOULD PLACE THE WAVE FARTHER NORTH...ALBEIT WEAK. 0-6KM SHEAR HAS STARTED TO INCREASE...AS EARLIER ANTICIPATED...FROM THE NORTHWEST MOUNTAINS INTO THE NORTHWEST PIEDMONT...AND IT IS EXPECTED THAT INCREASING CONVERGENCE WITH THE SHEAR NOTED ON MSAS WILL HELP TO GRADUALLY INCREASE COVERAGE OF SHOWERS AND THUNDERSTORMS FARTHER NORTH AND NORTHWEST OF MID-AFTERNOON DEEP CONVECTION. HAVE NOT GONE AS HIGH AS CATEGORICAL FOR THE EVENING WITH THIS ISSUANCE DUE TO SOME UNCERTAINTIES IN LOCATION. SEVERE POTENTIAL CONTINUES...MOSTLY PULSE OR MULTICELLULAR IN NATURE WITH ISOLATED DAMAGING WIND THE PRIMARY THREAT. BUFR SOUNDINGS WOULD INDICATE THAT 0-3KM HELICITY SHOULD REMAIN MOSTLY BELOW 100M2/S2...ALTHOUGH THIS EVENING MAINLY TOWARD KFAY AS THE WINDS ALOFT INCREASE SLIGHTLY...SUCH VALUES RISE JUST ABOVE 100M2/S2. BY THAT TIME...ANY STORMS SHOULD START TO BECOME MORE ELEVATED. OVERNIGHT...THE WEAK SHEAR AXIS ALOFT SHOULD REMAIN NEAR OR CLOSER TO THE SOUTHEAST COUNTIES. AS A WEAK 700MB SHORTWAVE FORECAST BY THE NAM MOVES IN FROM THE SOUTHWEST...AND WITH THE MCV EXITING BETWEEN 03Z AND 06Z...CHANCES FOR SHOWERS WILL CONTINUE MAINLY OVER THE COASTAL PLAIN AND PARTS OF THE SANDHILLS. OVERNIGHT LOW TEMPERATURES SHOULD RANGE FROM 70 TO 75 DEGREES...WARMEST TOWARD KFAY. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... AS OF 300 PM FRIDAY... WEAK DIFFLUENCE ALOFT CONTINUES SATURDAY...ENHANCED SLIGHTLY BY THE APPROACH OF TROUGHINESS ALOFT AND THE FAR SOUTHERN END OF A 60KT UPPER JET MOVING TOWARD THE MID-ATLANTIC. PRECIPITABLE WATER VALUES CONTINUE AROUND TWO INCHES...AND AS ANOTHER MID-LEVEL SHORTWAVE IS FORECAST TO MOVE ACROSS CENTRAL NORTH CAROLINA DURING THE DAY AS THE WEAKENING SURFACE FRONT SHOULD EDGE CLOSER TO THE VIRGINIA BORDER... THE LIKELIHOOD FOR SHOWERS AND THUNDERSTORMS IS GOOD ONCE AGAIN OVER CENTRAL NORTH CAROLINA BY AFTERNOON. THERE IS ALSO DECENT ADVECTION OF POTENTIAL VORTICITY ON THE 1.5PVU SURFACE FORECAST BY AFTERNOON. 1000-500MB LAPSE RATES ARE WEAKER THAN WHAT SHOULD RESULT TODAY... LESS THAN 6C/KM EXPECTED...WITH MINIMAL DCAPE AND LESSER MLCAPE AS WELL. WHILE AN ISOLATED SEVERE STORM CANNOT BE COMPLETED RULED OUT WITH...AGAIN...THE PRIMARY THREAT OF WIND...PRIMARY THREAT FOR SATURDAY SHOULD BE LOCALLY HEAVY RAIN...MAINLY IN THE TYPICAL URBAN OR POOR DRAINAGE AREAS. BIAS-CORRECTED MOS GUIDANCE TEMPERATURES ARE ACTUALLY A BLEND OF THE MAV AND MET GUIDANCE AND MOSTLY MID 80S NEAR THE VIRGINIA BORDER TO AROUND 90 TOWARD THE SOUTH CAROLINA BORDER. OVERNIGHT SATURDAY...THE NAM BUFR SOUNDINGS DRY THE MID- AND UPPER-LEVEL AIR MASS SOME...WITH A SLIGHT DECREASE IN OVERALL MOISTURE. THE GFS IS MORE MOIST OVERALL...AND WHILE LEANING TOWARD THE GFS...WOULD ANTICIPATE OVERALL COVERAGE OF SHOWERS AND ANY THUNDERSTORMS TO DIMINISH DIURNALLY. WILL STILL CONTINUE A CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH THE LATE EVENING AND EARLY OVERNIGHT HOURS...AND A SLIGHT CHANCE OVERNIGHT...BASED ON THE PROXIMITY OF THE FRONT...MOISTURE...AND ANY MID-LEVEL WAVE. OVERNIGHT LOWS ONCE AGAIN 70 TO 75 DEGREES. - DJF BY SUNDAY...MID LEVEL HIGH PRESSURE CENTERED OVER THE CENTRAL PLAINS WILL BUILD EASTWARD...WHILE THE BERMUDA HIGH WILL BUILD WESTWARD... RESULTING IN RISING HEIGHTS OVER THE REGION. THIS WILL RESULT IN BOTH THE MID LEVEL TROUGH AND THE SURFACE TROUGH WEAKENING ACROSS THE REGION. HOWEVER...AMPLE MOISTURE WILL PERSIST ACROSS THE FORECAST AREA...WITH PWAT VALUES PROGGED TO REMAIN ABOVE 2 INCHES. THUS...AM STILL EXPECTING SCATTERED SHOWERS AND STORMS...MAINLY DURING THE AFTERNOON/EVENING HOURS...HOWEVER GIVEN THE DIMINISHING DYNAMIC SUPPORT...CONVECTIVE COVERAGE SHOULD BE LESS THAN PREVIOUS DAYS. TEMPS WILL ALSO BEGIN TO WARM SLIGHTLY...BUT STILL SHOULD REMAIN NEAR TO SIGHTLY BELOW AVERAGE...GENERALLY IN THE UPPER 80S TO NEAR 90 DEGREES. OVERNIGHT LOWS ONCE AGAIN EXPECTED TO BE IN THE LOW TO MID 70S. - KRR && .LONG TERM /MONDAY THROUGH FRIDAY/... AS OF 300 PM FRIDAY... OVERALL...THE REGION IS EXPECTED TO BE INFLUENCED BY BROAD MID LEVEL RIDGING THAT WILL EXTEND FROM THE CENTRAL PLAINS INTO THE SOUTHEAST...WITH CENTRAL NC ON THE NORTHERN PERIPHERY OF THIS RIDGE. THEREFORE...WE WILL BE UNDER NORTHWESTERLY FLOW ALOFT FOR MUCH OF THE PERIOD AND HENCE THE POTENTIAL FOR WEAK DISTURBANCES TO IMPACT THE AREA WILL LIKELY BE OUR MAIN CHANCES FOR ANY PRECIP BEYOND TYPICAL SUMMERTIME CONVECTION. MODELS ALSO INDICATE (TO VARYING DEGREES) A BACK DOOR FRONT APPROACHING THE AREA MIDWEEK...BUT GIVEN THE TIME OF YEAR...WILL KEEP THE FRONT NORTH OF REGION FOR NOW. AS A RESULT...SINCE IT IS IMPOSSIBLE TO TIME ANY WEAK UPPER LEVEL DISTURBANCES THIS FAR OUT...AM EXPECTING MOSTLY ISOLATED TO SCATTERED DIURNAL TYPE PRECIP EACH DAY. THE HEAT WILL ALSO BEGIN TO RETURN TO THE REGION...WITH GENERALLY LOW 90S ON MONDAY TRENDING TO THE MID (MAYBE UPPER) 90S TOWARDS THE END OF THE WORK WEEK. OVERNIGHT LOW WILL REMAIN IN THE LOW TO MID 70S. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... AS OF 145 PM FRIDAY... VFR CONDITIONS WILL BE THE RULE OUTSIDE OF SHOWERS AND THUNDERSTORMS THROUGH THIS EVENING. SHOWERS AND THUNDERSTORMS WILL PRODUCE LOCALLY GUSTY WINDS...NOTE THE GUST TO 36KT AT KPOB AT 1718Z. OVERNIGHT... IT IS DIFFICULT TO ASSESS THE POTENTIAL FOR LOW CLOUDS. THE HIGHER WINDS JUST OFF OF THE SURFACE WILL BE TOWARD KFAY AND KRWI LATE TONIGHT...WHILE THE SREF MODEL HAS ITS HIGHEST PROBABILITIES MOSTLY FROM KGSO AND KRDU SOUTHWEST...AND HIGHER THAN IT INITIALIZED THIS MORNING WHEN MVFR AND LOCALLY IFR CEILINGS OCCURRED ACROSS CENTRAL NORTH CAROLINA. CONFIDENCE IS FAIRLY HIGH THAT THERE WILL BE AREAS OF MVFR CEILINGS IN CENTRAL NORTH CAROLINA...BUT THE LOCATION OF THE LOWER CEILINGS IS MORE UNCERTAIN. FOR THE 18Z VALID TAF...LEANED TOWARD THE SREF OUTPUT WITH THE TEMPORARY CONDITIONS OF IFR CLOUDS TOWARD KGSO AND KRDU...AND ONLY LOW MVFR CEILINGS AT KFAY AND KRWI LATE TONIGHT AND EARLY SATURDAY AFTER SUNRISE. BEYOND THE 18Z VALID TAF PERIOD...ANTICIPATE SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS DEVELOPING IN A MOIST AIR MASS AGAIN BY LATE SATURDAY MORNING...BECOMING MORE NUMEROUS DURING THE AFTERNOON AND CONTINUING INTO SATURDAY EVENING. REMAINING SHOWERS SHOULD BECOME MUCH MORE ISOLATED OR DIMINISH LATE SATURDAY NIGHT. SCATTERED SHOWERS AND THUNDERSTORMS OCCUR AGAIN SUNDAY...THEN ANY SHOWERS AND THUNDERSTORMS SHOULD TEND TO BECOME MORE ISOLATED EARLY NEXT WEEK AS THE COLD FRONT MOVING SOUTH CURRENTLY FROM VIRGINIA STALLS AND DISSIPATES. LATE NIGHT AND EARLY MORNING LOW CLOUDS ARE ALSO POSSIBLE...WITH THE LATEST GUIDANCE SUGGESTING A BETTER POTENTIAL LATE SATURDAY NIGHT INTO EARLY SUNDAY MORNING. && .RAH WATCHES/WARNINGS/ADVISORIES...
