Flash Flood in North Carolina, August 28, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
839 PM EDT TUE AUG 28 2012

.SYNOPSIS...
A SLOW MOVING COLD FRONT WILL MOVE INTO THE AREA THIS EVENING AND
OVERNIGHT. THE COLD FRONT WILL PUSH SOUTH INTO SOUTH CAROLINA LATE
WEDNESDAY AND THURSDAY AS HIGH PRESSURE BUILDS IN FROM THE NORTH.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 755 PM TUESDAY...

THREAT OF LOCALLY HEAVY ACROSS THE NORTHERN AND CENTRAL COUNTIES
WILL BE THE MAIN WEATHER HAZARD THIS EVENING INTO THE OVERNIGHT.

A LINE OF SHOWERS AND THUNDERSTORMS HAS DEVELOPED ALONG ALONG A
PRE-FRONTAL TROUGH DIVING SSE THROUGH SOUTHERN VA INTO NORTHERN NC.
THIS LINE HAS BEEN PRODUCING LOCALLY HEAVY RAIN WITH DOPPLER RADAR
HOURLY RAINFALL RATES ESTIMATED TO BE BETWEEN 2 AND 2.5 INCHES. MOST
LOCATIONS WERE EXPERIENCING HEAVY RAIN FOR 30 TO 45 MINUTES.
HOWEVER...THERE HAVE BEEN SOME MERGING OF CELLS AND BACKBUILDING OF
THE CONVECTION TO THE WEST AS THE LINE HAS BEEN SAGGING SLOWLY SOUTH
THROUGH PERSON/CASWELL/ROCKINGHAM COUNTIES. THIS LEAD TO THE FLOOD
ADVISORY FOR PERSON COUNTY RECENTLY. ADDITIONAL ADVISORIES AND/OR
FLASH FLOOD WARNINGS WILL BE POSSIBLE IN THE COMING HOURS.

THE RAIN TO OUR SOUTH...OVER FROM NEAR CHARLOTTE TO FAYETTEVILLE HAS
BEEN DISSIPATING. HOWEVER...THIS REGION IS RELATIVELY STABLE PER THE
LATEST SEVERE WEATHER PARAMETERS. IT APPEARS THAT THE LINE COMING IN
FROM THE NORTH WILL NOW BE THE MAIN PLAYER AS IT INTERACTS WITH THE
CONVERGENT AND VERY MOIST LOW LEVEL INFLOW FROM THE SOUTH INTO THE
FRONT. WE WILL RAISE POP TO LIKELY TO CATEGORICAL NORTH AND REDUCE
POP SOUTH.

THE LINE SHOULD SLOWLY ENTER THE WINSTON-SALEM TO GREENSBORO TO
BURLINGTON TO DURHAM URBAN CORRIDOR THROUGH 1000 PM. LOCALLY 1-3
INCHES OF RAIN WILL CREATE SOME RUNOFF PROBLEMS... ESPECIALLY IN
THESE URBAN CENTERS. -BADGETT

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
AS OF 245 PM TUESDAY...

WEDNESDAY AND WEDNESDAY NIGHT...
THE COLD FRONT IS FORECAST TO SINK SOUTH TO NEAR THE NC/SC BORDER ON
WEDNESDAY....AS HIGH PRESSURE BEGINS TO BUILD ACROSS THE OHIO VALLEY
REGION.  MODEL CONSENSUS SUGGEST MOST OF THE AREA WILL BE DRY...WITH
THE FOCUS OF SHOWERS AND STORMS NEAR THE FRONT.  WE HAVE CONTINUED
TO TRIM POPS ACROSS THE CENTRAL PIEDMONT...WITH CHANCE POPS NOW
PRIMARILY FROM STANLY COUNTY TO WAYNE COUNTY AND SOUTHWARD.  GIVEN
THE DOWNWARD TREND IN POPS/QPF...HIGHS SHOULD BE A DEGREE OR TWO
WARMER THAN PREVIOUSLY FORECAST...A NORTHERLY WIND SHOULD KEEP
READINGS RIGHT AROUND NORMAL IN THE MID 80S.  PRECIP SHOULD SHIFT
FURTHER SOUTH WEDNESDAY NIGHT AS THE FRONT WASHES OUT TO OUR SOUTH
AND RETURN FLOW HOLDS OFF UNTIL THURSDAY.  THUS...NO POPS ARE NEEDED
OVERNIGHT.  LOWS A TOUCH COOLER ACROSS THE NORTH WITH CLEARING
SKIES...MID 60S NORTH TO UPPER 60S SOUTH.

THU: 1022 MB SURFACE HIGH PRESSURE OVER LAKE HURON THIS AFTERNOON
WILL DRIFT SOUTHEASTWARD AND OFFSHORE THE MIDDLE ATLANTIC COAST ON
THURSDAY. NWP GUIDANCE IS IN GOOD AGREEMENT THAT THE PRECEDING LOW
LEVEL FRONTAL ZONE FORECAST TO MOVE THROUGH CENTRAL NC TONIGHT WILL
SETTLE TO NEAR THE SC STATE LINE BY THU MORNING...THEN PERHAPS
RETREAT SLIGHTLY NORTHWARD TOWARD THE SOUTHERN NC PIEDMONT WHILE
UNDERGOING FRONTOLYSIS IN RETURN SOUTHEASTERLY FLOW AROUND THE
HIGH...LATE THU INTO THU NIGHT. THE LOW LEVEL FRONTAL ZONE WILL BE
PROPELLED BY A STRONGLY POSITIVELY-TILTED TROUGH AXIS COMPOSED
ALMOST ENTIRELY OF SHEAR VORTICITY AND IS ACCORDINGLY DIFFICULT TO
IDENTIFY ON WV VAPOR IMAGERY THIS AFTERNOON...AND MAY NOT YET BE
WELL REPRESENTED BY NWP GUIDANCE...SO CONFIDENCE ON THE LOCATION OF
THE FRONT ON THU IS ONLY AVERAGE TO SLIGHTLY ABOVE AT THIS TIME. AS
SUCH...WILL MAINTAIN AN AFTERNOON SLIGHT TO CHANCE POP OVER THE
SOUTHERN PIEDMONT AND SANDHILLS TO ACCOUNT FOR THIS UNCERTAINTY...
BUT BOTH DRIER BL AND DEEP LAYER MOISTURE...AND SUBSIDENCE/CAPPING
ALOFT IN THE WAKE OF THE TROUGH AXIS ALOFT...SUGGESTS THE REMAINDER
OF CENTRAL NC SHOULD BE DRY. PROJECTED LOW LEVEL THICKNESS VALUES
AROUND 1410 METERS...WITH PARTLY CLOUDY (TO PERHAPS A PERIOD OF
MOSTLY SO INVOF THE FRONT NEAR THE SC STATE LINE)...SUPPORT HIGH
TEMPERATURES RELATIVELY UNIFORMLY IN THE MIDDLE 80S.

THU NIGHT: THE SURFACE RIDGE AXIS IS FORECAST TO EXPAND FROM
OFFSHORE WESTWARD ACROSS NC AND THE SOUTHERN/CENTRAL APPALACHIANS
OVERNIGHT...AS A FAIRLY STOUT MID LEVEL RIDGE CHARACTERIZED BY H7
HEIGHTS OF AROUND 321-322 DM MIGRATES SOUTHEASTWARD TOWARD THE
MIDDLE ATLANTIC STATES. EXCELLENT RADIATIONAL COOLING CONDITIONS
SHOULD ACCOMPANY THE EXPANDING RIDGE AXIS...BENEATH A MOSTLY CLEAR
SKY...WITH WIDE RANGING LOWS FROM THE LOWER TO UPPER 60S BETWEEN
RURAL/TYPICALLY COOLER AND URBAN AREAS.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
AS OF 305 PM TUESDAY...

FRI-SAT NIGHT: WARMER AND MAINLY DRY. THE AFOREMENTIONED MID LEVEL
RIDGE AND ASSOCIATED LOW LEVEL THERMAL RIDGE WILL DRIFT FROM INTO
THE MIDDLE ATLANTIC STATES/CAROLINAS FRI-SAT. FORECAST H85
TEMPERATURES ACCORDINGLY CLIMB TO AROUND 20-21C CENTERED OVER VA/NC
DURING THIS TIME...WHICH SHOULD SUPPORT HIGH TEMPERATURES IN THE
UPPER 80S TO LOWER 90S -- WARMEST SAT -- BOTH DAYS. LOWS WITHIN A
COUPLE OF DEGREES OF 70. CONVECTIVE POTENTIAL WILL REMAIN QUITE
LOW...AND HAS BEEN LEFT OUT OF THE FORECAST GIVEN THE SUBSIDENT AND
CAPPING INFLUENCE OF THE RIDGE ALOFT...DESPITE SHALLOW LOW LEVEL
CONVERGENCE WITHIN THE PIEDMONT SURFACE TROUGH AXIS AND BL MOISTURE
GRADIENT.

SUN-TUE: BASED ON THE LATEST NHC FORECAST POSITION OF THE REMNANTS
OF ISAAC OVER NORTHERN IN AT 12Z SUN...AND THE CONSENSUS OF GUIDANCE
MOVING THE SHEARED REMNANTS GENERALLY EASTWARD AROUND THE NORTHERN
PERIPHERY OF THE MID LEVEL RIDGE...IT APPEARS THAT SENSIBLE WEATHER
IMPACTS FOR CENTRAL WILL BE RELATIVELY MINIMAL. AS ISAAC BECOMES
ABSORBED IN THE WESTERLIES...A NORTHERN STREAM FRONTAL SYSTEM WILL
OVERTAKE THE SYSTEM AND DRAG AN ASSOCIATED SURFACE FRONTAL ZONE --
AND A RELATIVE MAXIMUM OF CONVECTIVE CHANCES (IN THE 30-40 PERCENT
RANGE) -- THROUGH CENTRAL NC IN THE MON-TUE TIME FRAME. HOWEVER...
SINCE THE MAIN BELT OF THE WESTERLIES IN THE NORTHERN STREAM AND
ASSOCIATED STEERING INFLUENCES IS FORECAST TO REMAIN NEAR THE
CANADIAN BORDER THROUGH THE PERIOD...FORECAST UNCERTAINTY REGARDING
THE TIMING AND TRACK OF THE REMNANTS IS AVERAGE TO BELOW; AND THIS
IS APPARENT BY THE WIDE MEDIUM RANGE MODEL SOLUTION SPREAD.
TEMPERATURES SHOULD ALSO COOL BACK TO MORE SEASONABLE LEVELS IN THE
MIDDLE TO UPPER 80S AS THE PRECEDING RIDGE ALOFT IS SUPPRESSED BY
THE NORTHERN STREAM/ISAAC REMNANTS.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
AS OF 830 PM TUESDAY...

24-HR TAF PERIOD:
A LINE OF SHOWERS AND THUNDERSTORMS WILL AFFECT THE INT/GSO
TERMINALS BETWEEN 00-03Z...AND LIKELY THE RDU TERMINAL IN THE
01-04Z TIME FRAME. THOUGH LESS LIKELY THAN RDU...THE RWI TERMINAL
POTENTIALLY BE AFFECTED BETWEEN 02-04Z. ANTICIPATE THE CURRENT LINE
OF SHOWERS/STORMS TO GRADUALLY WEAKEN AND EVENTUALLY DISSIPATE
BETWEEN 03-06Z. SOUTHWESTERLY LOW-LEVEL FLOW WILL ADVECT AN
INCREASINGLY MOIST/STABLE AIRMASS NORTH OF THE HIGHWAY 64 CORRIDOR
OVERNIGHT...AND EXPECT MVFR CEILINGS TO DEVELOP BY 03-06Z...WITH
IFR/LIFR CEILINGS DEVELOPING BETWEEN 06-12Z. ANTICIPATE IFR/LIFR
CEILINGS TO LIFT AND SCATTER OUT TO VFR AT THE INT/GSO/RDU/RWI
TERMINALS BETWEEN 12-15Z. AT THE FAY TERMINAL...IFR/MVFR CEILINGS
MAY LINGER THROUGH 15-18Z BEFORE SCATTERING OUT TO VFR WED
AFTERNOON.

LOOKING AHEAD:
ASIDE FROM A POTENTIAL FOR MVFR/IFR CEILINGS AT THE FAY TERMINAL
BETWEEN 06-12Z THU MORNING...EXPECT VFR CONDITIONS TO PREDOMINATE
OVER CENTRAL NC THU-SAT AS AN UPPER LEVEL RIDGE BUILDS OVER THE
MID-ATLANTIC AND CAROLINAS. CONFIDENCE IN THE FORECAST DECREASES
SUNDAY INTO EARLY NEXT WEEK...PRIMARILY DUE TO UNCERTAINTY IN THE
EVOLUTION OF THE REMNANTS OF TROPICAL CYCLONE ISAAC. -VINCENT
