A mid/upper level through axis was located across western North Carolina. As a disturbance aloft rotated through the base of the trough and eventually over our region in the southwesterly flow aloft, scattered showers and thunderstorms developed during the heating of the day, with a couple of the storms becoming severe in the moderately unstable air mass.

The episode as NWS RAH wrote it up.

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 Aug 1, 2:27 PM EST, 1 hour 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 327 PM EDT WED AUG 1 2012 .SYNOPSIS... A SERIES OF UPPER LEVEL DISTURBANCES WILL MOVE SOUTHEAST INTO THE CAROLINAS THROUGH THURSDAY. UPPER LEVEL HIGH PRESSURE WILL THEN BUILD INTO THE REGION THROUGH THE WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... AS OF 325 PM... IN BROAD LARGE SCALE ASCENT AHEAD OF A MID-UPPER TROUGH AXIS OVER EAST-CENTRAL NC...INITIAL STORMS OVER THE COASTAL PLAIN SEEMED TO HAVE BEEN FOCUSED ALONG A DIFFERENTIAL HEATING BOUNDARY AT THE EDGE OF MVFR RANGE CLOUD COVER OVER THE COASTAL PLAIN EARLIER THIS MORNING...WHICH WAS FURTHER ENHANCED BY A SMALL AREA OF MID LEVEL CLOUDS THAT HAVE SINCE DISSIPATED. THIS RELATIVELY SLOW MOVING ACTIVITY SHOULD CONTINUE TO PERCOLATE ALONG OUTFLOW OVER THE COASTAL PLAIN DURING THE NEXT COUPLE OF HOURS. MEANWHILE...ADDITIONAL MORE WIDELY SCATTERED STORMS HAVE DEVELOPED WITHIN AN INSTABILITY AXIS CHARACTERIZED BY AROUND 2500 J/KG OF MLCAPE OVER THE PIEDMONT... WHERE TEMPERATURES WARMED MORE READILY THAN AREAS AFFECTED BY THE AFOREMENTIONED CLOUDS IN THE EAST. THESE STORMS...HOWEVER...HAVE STRUGGLED TO ATTAIN MUCH DEPTH LIKELY DUE TO BOTH DRY AIR ENTRAINMENT AND DNVA TO THE WEST OF THE MID-UPPER TROUGH AXIS. THESE STORMS...AND MORE LIKELY ONES SPREADING SOUTHEASTWARD FROM WESTERN NC...MAY GROW IN COVERAGE AND INTENSITY DURING THE LATE AFTERNOON AND EVENING HOURS OWING TO THE APPROACH OF AN UPSTREAM MID-UPPER IMPULSE OVER NE KENTUCKY. IF STORMS INDEED ARE ABLE TO OVERCOME THE DRY AIR ALOFT...THE DRY AIR AND ASSOCIATED DCAPE WOULD ENHANCE THE LIKELIHOOD OF DOWNDRAFT ACCELERATIONS AND RESULTANT THREAT OF ISOLATED DAMAGING WINDS. THE PRESENCE OF THE TROUGH ALOFT AND ASSOCIATED UNSEASONABLY LOW FREEZING LEVELS BETWEEN 12 AND 14 THOUSAND FEET FROM WEST TO EAST ALSO SUGGESTS SOME SMALL TO MARGINALLY SEVERE HAIL WILL BE A THREAT. WHILE Q-G FORCING FOR ASCENT AHEAD OF THIS FEATURE SHOULD IMPROVE STEADILY AS THE IMPULSE AMPLIFIES ACROSS THE CENTRAL APPALACHIANS THROUGH EARLY THU...PRESENT INDICATIONS ARE THAT NOCTURNAL COOLING AND ASSOCIATED CINH WILL LIKELY PROVE TOO GREAT TO OVERCOME TO SUSTAIN CONVECTION PAST MIDNIGHT...UNLESS STORM COVERAGE TO THE NORTHWEST BECOMES GREAT ENOUGH FOR STRONGER AGGREGATE OUTFLOW AND ASSOCIATED LOW LEVEL FORCING. LOWS WITHIN A COUPLE OF DEGREES OF 70. && .SHORT TERM /THURSDAY THROUGH SATURDAY NIGHT/... AS OF 150 PM... SHORT WAVE NORTH OF THE OHIO VALLEY THIS AFTERNOON WILL DROP INTO THE NORTH CAROLINA MOUNTAINS TONIGHT AND CROSS CENTRAL NORTH CAROLINA DURING THE MORNING HOURS. NO SIGNIFICANT LOW LEVEL FORCING AND PRECIPITABLE WATERS PERHAPS AS LOW AS 1.25 INCHES. THE SHORT WAVE IS FORECAST TO BE STRONG ENOUGH TO WARRANT A RISK FOR ISOLATED THUNDERSTORMS DURING THE MORNING... WITH NORTHEAST PARTS LEAST LIKELY TO SEE RAIN. SOME SUBTLE MODEL DIFFERENCES IN PLACEMENT OF A WEAK SURFACE TROUGH FOR THE AFTERNOON. SOMEWHAT HIGH...DRY INVERTED VEE... MIXING HEIGHTS ACROSS THE NORTHWEST WILL LIMIT OR ELIMINATE CONVECTION THERE. WITH LITTLE WEAK WINDS AND ONLY HEATING AS A SIGNIFICANT CONVECTIVE TRIGGER... SEE NO MORE THAN SLIGHT RAIN CHANCES... MAINLY NEAR AND EAST OF HIGHWAY ONE. SEE LITTLE REASON FOR CONVECTION TO PERSIST PAST THE EARLY EVENING AND THE MAJORITY OF THE NIGHT TIME HOURS THROUGH THIS ENTIRE FORECAST PERIOD SHOULD BE DRY. MID LEVEL WINDS INCREASE SUBTLY FRIDAY BUT STILL UNDER FIFTEEN KNOTS. RAIN CHANCES CONTINUE TO LOOK SMALLEST NORTHWEST WHERE DRYNESS ABOVE 12000 FEET IS GREATEST. RAIN CHANCES MINIMALLY HIGHER THAN THURSDAY... BUT STILL NO MORE THAN ONE IN FIVE. THE PRESSURE GRADIENT ALOFT INCREASES OVER NORTH CAROLINA AS HIGH PRESSURE OFFSHORE BUILDS AS A LOW NORTH OF THE GREAT LAKES DEEPENS AND MOVES EAST. PRECIPITABLE WATERS PERHAPS EXCEEDING 1.75 INCHES WITH AVERAGE INSTABILITY AND POTENTIAL ENERGY AVAILABLE. RAIN CHANCES SATURDAY AFTERNOON NOT FAR FROM CLIMATOLOGY... AT ABOUT ONE IN FIVE NORTHWEST TO ONE IN THREE SOUTHEAST. 1000 TO 850 MILLIBAR THICKNESSES FOR THIS PERIOD NEAR CLIMATOLOGY AND TEMPERATURES WILL FOLLOW SUIT. MODELS INDICATE A SLIGHT DIP SATURDAY AFTERNOON... LIKELY IN RESPONSE TO MORE CLOUDINESS THAN THURSDAY OR FRIDAY. OVERNIGHT LOW TEMPERATURES UPPER 60S TO LOWER 70S. AFTERNOON HIGH TEMPERATURES MOSTLY LOWER 90S... EXCEPT UPPER 80S TO LOWER 90S SATURDAY. && .LONG TERM /SUNDAY THROUGH TUESDAY/... AS OF 1055 AM WEDNESDAY... FOLLOWING THE ECMWF ENSEMBLE MEAN AND GEFS MEAN AS PREFERRED BY HPC... EXPECT THIS TO BE A VARIABLE CLOUDY AND HUMID PERIOD WITH HIGH AND LOW TEMPERATURES RUNNING WITHIN A DEGREE OR TWO OF SEASONAL NORMALS. A NORTHERN STREAM MID LEVEL TROUGH OVER EASTERN ONTARIO AND THE GREAT LAKES EARLY SUNDAY SLIDES EASTWARD ACROSS SE CANADA AND THE SAINT LAWRENCE VALLEY AND NORTHEAST STATES THROUGH MONDAY...BRINGING ITS ASSOCIATED COLD FRONT EAST TOWARD THE APPALACHIANS ON SUNDAY... THEN ALLOWING IT TO STALL ON MONDAY AS THE WAVELENGTH TO OUR NORTH BROADENS AND DEAMPLIFIES A BIT. ATLANTIC RIDGING PRECEDING THIS TROUGH SHOULD HELP SUPPRESS MOST DEEP CONVECTION OVER CENTRAL NORTH CAROLINA SUNDAY (AND PERHAPS INTO MONDAY IF THE SLOWER ECMWF IS CORRECT)... ALTHOUGH THE LOW LEVEL ONSHORE DIRECTED FLOW SOUTHEASTERLY AND SOUTHERLY FLOW AND ABOVE NORMAL PRECIPITABLE WATER IN PLACE MAY PROMOTE PATCHY SHOWERS OVER THE AREA ON SUNDAY. THE CHANCE OF SHOWERS AND STORMS IS LIKELY TO INCREASE ON MONDAY AS THE SURFACE FRONT HOLDS UP JUST TO OUR NORTHWEST WITH THE SOUTHERN REACHES OF THE DAMPENING AND DEPARTING TROUGH SHIFTING OVERHEAD... YIELDING A SUBTLE WEAKNESS IN MID LEVEL HEIGHTS OVER THE AREA... EXTENDING FROM OFF THE MID ATLANTIC COAST THROUGH THE CAROLINAS AND INTERIOR SOUTHEAST. AS THE MODELS DEPICT THE MID LEVEL TROUGH RELOADING WITH FALLING HEIGHTS OVER MANITOBA/ONTARIO/HUDSON BAY TUESDAY INTO WEDNESDAY... THIS MID LEVEL WEAKNESS ALOFT IS LIKELY TO HOLD IN OUR VICINITY THROUGH AT LEAST WEDNESDAY. THE COMPARATIVELY COOL SURFACE HIGH THAT BECOMES CENTERED OVER THE LOWER GREAT LAKES BY LATE MONDAY APPEARS UNLIKELY TO POSSESS ENOUGH DENSE AIR TO PUSH THE SURFACE FRONT FULLY THROUGH OUR AREA... AND THIS SHOULD RESULT IN A SLOW WEAKENING AND DISSIPATION OF THE BROAD DIFFUSE SURFACE FRONT THROUGH MIDWEEK... VERY TYPICAL OF SUMMERTIME FRONTAL BEHAVIOR IN THIS REGION. WITH PRECIPITABLE WATER EXPECTED TO HOLD ABOVE NORMAL... IN THE 1.6 TO 2.0 INCH RANGE... WE SHOULD SEE MORE CLOUDS THAN SUN AND DAILY SCATTERED AFTERNOON THROUGH EVENING THUNDERSTORMS... WITH LITTLE OPPORTUNITY TO PROVIDE SPECIFICITY REGARDING TIMING AND LOCATION GIVEN THE DAMP AND LOW SHEAR PATTERN AND THE ABSENCE OF STRONG LARGE SCALE FORCING FOR ASCENT. STATISTICAL GUIDANCE AND MODEL-PROJECTED THICKNESSES SUPPORT TEMPERATURES CLOSE TO NORMAL... WITH LOWS IN THE UPPER 60S TO LOWER 70S... AND HIGHS IN THE UPPER 80S TO LOWER 90S EACH DAY. -GIH && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... AS OF 210 PM... SCATTERED SHOWERS AND A THUNDERSTORM OR TWO WEST OF INTERSTATE 95 AT THIS TIME... WITH ISOLATED SHOWERS NEAR AND EAST OF HIGHWAY 501. THE WESTERN PIEDMONT REMAINS LEAST LIKELY TO SEE RAIN THIS AFTERNOON. SHOWERS MAY PERSIST OR DEVELOP LATE TONIGHT WITH THE ARRIVAL OF AN UPPER LEVEL DISTURBANCE FROM THE NORTHWEST. MOSTLY MVFR FOG TONIGHT... PERHAPS BEFORE MIDNIGHT EAST AND VICINITY OF INTERSTATE 95... WHERE SCATTERED LOW STRATUS CLOUDS POSSIBLE. CONVECTION AGAIN POSSIBLE WEDNESDAY AFTERNOON. AFTERNOON STORMS AND EARLY MORNING STRATUS OR FOG WILL BE POSSIBLE EACH DAY THROUGH THE WEEKEND...WITH A BETTER CHANCE OF STORMS EARLY NEXT WEEK. && .RAH WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS... NEAR TERM...MWS SHORT TERM... LONG TERM...HARTFIELD AVIATION...
