A deep upper level low pressure system was pinwheeling across Tennessee, while high pressure was wedged against the eastern face of the Appalachians. Breaks in the cloud cover across northern North Carolina added to the surface-based instability, which allowed thunderstorms across the area to intensify to severe levels during the evening.

The episode as NWS RNK wrote it up.
A deep upper level low pressure system was pinwheeling across Tennessee, while high pressure was wedged against the eastern face of the Appalachians. Breaks in the cloud cover across northern North Carolina added to the surface-based instability, which allowed thunderstorms across the area to intensify to severe levels during the evening.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
151 AM EDT MON MAY 6 2013
.SYNOPSIS...
UPPER LOW IN THE NORTHERN SECTIONS OF ALABAMA/GEORGIA EARLY THIS
MORNING WILL SLOWLY SHIFT EAST INTO NORTH CAROLINA BY TUESDAY BEFORE
SHIFTING TOWARD THE ATLANTIC COAST ON TUESDAY NIGHT. THE PASSAGE
OF THIS SYSTEM WILL RESULT IN AN EXTENDED PERIOD OF MODERATE TO
OCCASIONALLY HEAVY RAIN...ALONG WITH A CONTINUATION OF COOL
TEMPERATURES ACROSS THE REGION.
&&
.NEAR TERM /THROUGH TODAY/...
AS OF 120 AM EDT MONDAY...
KEPT FORECAST GENERALLY THE SAME ALTHOUGH REDUCED POPS FURTHER
NORTH AND OUTSIDE THE UPSLOPE AREAS ACROSS SE WV. NOT OUT OF THE
QUESTION THAT THE NC MTNS/SW VA BLUE RIDGE GET ANOTHER 0.50 TO 1
INCH OF RAIN BETWEEN NOW AND 900 AM MONDAY.
PREVIOUS FORECAST DISCUSSION...
RAINFALL HAD SPREAD NORTH AND HAD NEARLY REACHED THE NORTHEAST
COUNTIES OF THE FORECAST AREA. RAINFALL RATES OF 0.2 TO 0.3
INCHES PER HOUR WERE COMMON WITH HEAVIER RAIN PRODUCING CLOSER TO
0.5 INCHES PER HOUR. SO FAR THE HEAVIEST RAINFALL AMOUNTS SINCE
MIDNIGHT HAVE BEEN IN NORTHWEST NORTH CAROLINA. THIS HAS CAUSED
FLOODING OF SEVERAL SMALL STREAMS IN WATAUGA COUNTY.
THE UPPER LOW WAS OVER NORTHEAST ALABAMA WITH THE ASSOCIATED
SURFACE LOW OVER NORTHERN GEORGIA. VERY SLOW MOVEMENT OF THESE
FEATURES IS EXPECTED OVERNIGHT. HAVE ADJUSTED PROBABILITY OF RAIN
TO REFLECT CURRENT RADAR TRENDS. EVENING SOUNDINGS SHOWED A LAYER
OF STRONG SOUTHEAST WINDS AND DEEP MOISTURE. LITTLE CHANGE NEEDED
TO MINIMUM TEMPERATURES.
HIGH PRESSURE WHICH HAS BEEN WEDGED AGAINST THE EASTERN FACE OF
THE APPALACHIANS FOR THE LAST WEEK WILL MAINTAIN AN EAST ONSHORE
WINDFLOW...WHICH WILL BE GUSTY AT TIMES AS THE PRESSURE GRADIENT
ACROSS OUR REGION TIGHTENS. WIND SPEED AND DIRECTION IS NOT IDEAL
TO REACH ADVISORY LEVEL GUSTS IN THIS AREA...BUT GUSTS WILL STILL
BE STRONG ENOUGH...WHEN CONSIDERING WET SOIL CONDITIONS...TO TAKE
DOWN SOME TREES.
WITH RAINFALL WIDESPREAD FROM LATE TONIGHT THROUGH MONDAY
EVENING...DO NOT SEE THE POTENTIAL FOR MUCH CHANGE BETWEEN
OVERNIGHT LOWS AND HIGHS FOR TOMORROW. UNDERCUT FORECAST GUIDANCE
BY SEVERAL DEGREES FOR MONDAY HIGHS BASED ON TEMPERATURE TRENDS OF
TODAY...AND BECAUSE OF THE WIDESPREAD RAIN FOR TOMORROW.
&&
.SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/...
AS OF 400 PM EDT SUNDAY...
MODELS CONTINUE TO SHOW REASONABLY GOOD CONTINUITY AND RUN TO RUN
CONSISTENCY WITH HANDLING OF SLOW EWD MOVING UPR LOW WHICH IS
FORECAST TO MOVE FROM THE SOUTHERN APPALACHIANS MONDAY TO THE MID
ATLANTIC COAST BY WEDNESDAY. AT THIS SNAILS SORT OF PACE...LOOK FOR
A S STEADY MDT TO OCCASIONALLY HEAVY AREA OF RAIN TO TRACK JUST
AHEAD OF THE ADVANCING UPR LOW. THIS WILL LIKELY IMPACT THE ENTIRE
CWA DURING THE CYCLONES JOURNEY TO THE MID ATLANTIC COAST...WITH AN
AREA OF ENHANCED RAINFALL ALONG THE EASTERN SLOPES OF THE BLUE RIDGE
WHERE UPSLOPE FLOW WILL ADD TO THE RAIN EFFICIENCY. THE FAVORABLE
FLOW PATTERN SUPPORTS HEAVY PCPN AMOUNTS...WITH MODELS SUGGESTING 2
TO AS MUCH AS 5 INCHES ALONG THE BLUE RIDGE PARKWAY. WHILE THIS
WILL BE MORE OF LONG DURATION TYPE RAINFALL EVENT...RUNOFF ISSUES
WITH THIS SORT OF RAINFALL ARE STILL LIKELY...IMPACTING POOR
DRAINAGE AREAS...LOW WATER CROSSINGS...AND SMALL STREAMS. AT SOME
POINT...RIVERS...ESPECIALLY THOSE NEAR THE BLUE RIDGE...MAY
EXPERIENCE HIGH WATER ISSUES.
AS WE PROGRESS INTO WEDNESDAY...THE CENTER OF THE UPPER LOW IS
PROGGED TO PROGRESS FAR ENOUGH EAST THAT UPSLOPE FLOW WILL CEASE. AT
THAT POINT WE WILL STILL BE SUBJECT TO WRAP AROUND MOISTURE WITHIN
THE DEFORMATION ZONE. RAIN SHOULD TAPER TO SCATTERED SHOWERS BY
THURSDAY ONCE THE SYSTEM PASSES OFF THE COAST.
ABUNDANT CLOUD COVER AND PRECIP WILL KEEP TEMPERATURES COOLER THAN
NORMAL THROUGH MID WEEK...TEMPERATURES REMAINING WITHIN ABOUT A 10
DEGREE SPREAD BETWEEN THE HIGHS AND THE LOWS.
&&
.LONG TERM /THURSDAY THROUGH SUNDAY/...
AS OF 400 PM EDT SUNDAY...
THE CLOSED UPPER LOW FINALLY EXITS THE PICTURE FOR THE END OF THE
WEEK. BEHIND THIS SYSTEM THICKNESSES INCREASE YIELDING WARMER
TEMPERATURES GOING INTO NEXT WEEKEND. THE MODELS DO HINT AT A
FAIRLY STRONG UPPER LEVEL TROUGH TO MOVE THROUGH THE NORTHERN PLAINS
AND UPPER MID WEST BY THE WEEKEND. THIS SHOULD SEND A COLD FRONT
OUR WAY OVER THE WEEKEND. WARMER TEMPERATURES AND MOIST SOUTHWEST
FLOW AHEAD OF THIS SYSTEM SUGGESTS THERE WILL BE A THREAT FOR
SHOWERS...AND THUNDERSTORMS...SOMETHING MORE TYPICAL OF SPRING
WEATHER AS OPPOSED TO THE COOL BLOCKY FLOW OF THE LAST 7 DAYS.
&&
.AVIATION /06Z MONDAY THROUGH FRIDAY/...
AS OF 140 AM EDT MONDAY...
KEEPING CIGS DOWN TO MVFR OR IFR THROUGH THE PERIOD. RAINFALL
WORKS NORTH AND ENCOMPASSES ALL TAF SITES BY 12Z MONDAY. RAIN WILL
BE MODERATE TO HEAVY AT TIMES WHERE VSBYS COULD DROP TO IFR...BUT
OVERALL MOST VSBYS SHOULD STAY IN THE 4-6SM RANGE. WHEN INTENSITY
OF RAIN PICKS UP SOME CIGS COULD ACTUALLY RISE TO MVFR BUT THEN
DROP BACK TO SUB 1KFT WHEN IT LIGHTENS UP...SO OVERALL KEEPING IT
PESSIMISTIC AND USING THE LOCAL WRF DEPICITION OF HEAVIER BANDS TO
WORK IN MVFR.
WINDS WILL BE GUSTY OUT OF THE EAST THRU AT LEAST THE
MORNING...THEN SUBSIDE AT TIMES AROUND 10 KNOTS. COULD SEE GUSTS
TO 30 KNOTS AT BLF/BCB EARLY BEFORE TAPERING OFF.
THE STORM SYSTEM WILL BE KEEPING US IN THE RAIN/SUB VFR WX THROUGH
TUESDAY WITH IT FINALLY TRACKING EAST BY WED. WEDNESDAY SHOWERY ON
THE BACKSIDE OF THE CIGS MAY RISE TO VFR EAST OF THE MTNS BUT
HAVE A FEELING ROA/BCB AND WEST CONTINUE SOMEWHERE IN THE MVFR
RANGE.
TAF LOCATIONS SHOULD RETURN TO VFR ON THURSDAY AS THE LOW BEGINS
TO PULL AWAY FROM THE MID ATLANTIC REGION. THE IMPROVEMENT WILL BE
SHORT LIVED AS ANOTHER DISTURBANCE WILL WILL BRING A CHANCE OF
IFR/MVFR CEILINGS AND VSBYS THIS WEEKEND.
&&
.HYDROLOGY...
AS OF 955 PM EDT SUNDAY...
A FLOOD WATCH CONTINUES FOR THE BLUE RIDGE FROM BOTETOURT COUNTY
SOUTH...AND AS FAR WEST AS THE MOUNTAIN EMPIRE AND NORTHWEST
NORTH CAROLINA. OROGRAPHIC LIFT ALONG THE BLUE RIDGE IN NORTHERN
NORTH CAROLINA HAS RESULTED IN VERY EFFICIENT RAINFALL
RATES...WITH 0.25 TO 0.4 INCHES FALLING PER HOUR.
THE MAIN FLOODING THREAT WILL OCCUR IN THE FORM OF AREAL FLOODING
RATHER THAN FLASH FLOODING...WHERE FLOODING WILL OCCUR MAINLY IN
RIVERS AND STREAMS OVER A LONGER TIME FRAME. ULTIMATELY...WILL BE
LOOKING FOR A STORM TOTAL OF 4 TO LOCALLY 6 INCHES ALONG THE BLUE
RIDGE SOUTH OF ROANOKE...WITH AROUND 2 TO 4 INCHES FALLING WITHIN
THE REMAINDER OF THE WATCH AREA.
