AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
811 PM EDT THU AUG 19 2010

.SYNOPSIS...
A COLD FRONT WILL DRIFT SLOWLY SOUTHWARD THROUGH NORTH CAROLINA
TODAY. HIGH PRESSURE WILL BUILD IN FROM THE NORTH LATE TONIGHT
THROUGH SATURDAY.

&&

.NEAR TERM /THROUGH FRIDAY/...
AS OF 250 PM THURSDAY...

     FLASH FLOOD WATCH REMAINS IN EFFECT TROUGH MIDNIGHT
TONIGHT...

LATEST SFC ANALYSIS CONTINUES TO INDICATE A QUASISTATIONARY FRONT
EXTENDING FROM EASTERN TENNESSEE EAST NORTHEAST TO NEAR RICHMOND
VIRGINIA. THE FRONT HAS MADE VERY LITTLE SOUTHWARD PROGRESS IN
VIRGINIA AS SOUTHERLY WINDS ARE NOW REPORTED IN CHARLES CITY AND
WEST POINT. SLIGHTLY LOWER DEW POINTS HAVE MOVED INTO SOUTHERN
PENNSYLVANIA AND MARYLAND THIS AFTERNOON. SOUTH OF THE FRONT
SURFACE DEW POINTS ARE IN THE MID 70S ACROSS CENTRAL NORTH
CAROLINA.

A VERY MOIST AIR MASS REMAINS IN PLACE AS THE MORNING SOUNDING AT
KGSO REPORTED PRECIPITABLE WATER OF 2.24 WHICH IS IN THE 99TH
PERCENTILE AND 2 STANDARD DEVIATIONS OF NORMAL. KMHX HAD A
PRECIPITABLE WATER OF 2.45 INCHES. BLENDED TOTAL PRECIPITABLE
WATER PRODUCT NOW INDICATES A LARGE AREA OF PRECIPITABLE WATER
RANGING AROUND 2.5 INCHES ACROSS THE CENTRAL AND EASTERN
CAROLINAS.

VISIBLE SATELLITE SHOWS AN INCREASING NUMBER OF BREAKS IN THE
OVERCAST ACROSS SOUTHERN NORTH CAROLINA WHERE TEMPERATURES ARE
NOW IN THE MID 80S WITH DEW POINTS IN THE MID 70S YIELDING MLCAPE
VALUES NOW NEAR 1500. EVEN IN CENTRAL NORTH CAROLINA WHERE THE LOW
CLOUDS HAVE BEEN MORE STUBBORN SOME THIN SPOTS/BREAKS ARE NOW
EVIDENT - EVEN OUTSIDE THE WINDOW HERE IN WEST RALEIGH. GIVEN THE
LOW CLOUDS AND RAIN THIS MORNING...INSTABILITY IN THE PIEDMONT OF
NORTH CAROLINA IS LIMITED BUT GIVEN THE HIGH DEW POINTS...THE
INSTABILITY HAS THE POTENTIAL TO JUMP UPWARD IF JUST A LITTLE
SUNSHINE IS REALIZED.

LATEST REGIONAL RADAR IMAGERY SHOWS CONVECTION FIRING IN VARIOUS
LOCATIONS ACROSS THE REGION FROM DIFFERENT MECHANISMS. THUNDERSTORMS
HAVE QUICKLY DEVELOPED NEAR KILM/KMYR DURING THE PAST HOUR IN A
AREA OF ENHANCED INSTABILITY AND CONVERGENCE NEAR A REGION OF
DIFFERENTIAL HEATING AND NEAR THE LAND/SEA INTERFACE. A LARGE AREA
OF SHOWERS WITH EMBEDDED THUNDERSTORMS IN FAR NORTHWEST NORTH
CAROLINA AND SOUTHWEST VIRGINIA IS ASSOCIATED WITH MID LEVEL
TROUGHINESS AND CONVERGENCE. MORE SCATTERED CONVECTION IS
DEVELOPING ACROSS THE HIGHER TERRAIN IN THE SOUTHERN APPALACHIANS
DOWNSTREAM OF A SHEAR AXIS VISIBLE ON WATER VAPOR IMAGERY. OTHER
ISOLATED CONVECTION IS NOW BEGINNING TO DEVELOP NEAR ROCK HILL
SOUTH CAROLINA AND JUST WEST OF THE CHARLOTTE REGION.

LATEST HIGH RESOLUTION NWP GUIDANCE SUGGESTS THAT THE SHOWERS AND
THUNDERSTORMS WILL MOVE INTO AND DEVELOP ACROSS THE WESTERN AND
NORTHERN PIEDMONT DURING THE NEXT FEW HOURS AND PUSH EASTWARD. OTHER
THUNDERSTORMS WILL DEVELOP ACROSS THE COASTAL PLAIN LATE THIS
AFTERNOON. THUNDERSTORMS SHOULD BE EFFICIENT RAIN PRODUCERS GIVEN
THE DEEP MOISTURE IN PLACE AS NOTED WITH THE HIGH PRECIPITABLE
WATERS. HEAVY RAINFALL WITH LOCALIZED FLOODING IS A REAL
POSSIBILITY THIS AFTERNOON AND EVENING. SOME LOCATIONS ACROSS
CENTRAL NORTH CAROLINA HAVE RECEIVED SEVERAL INCHES OF RAIN DURING
THE PAST FEW DAYS FURTHER ENHANCING THE RISK. SEVERE THREAT IS
MINIMAL AND SHOULD BE FOCUSED IN THE REGION OF GREATEST
INSTABILITY IN THE SOUTHERN PIEDMONT...SANDHILLS AND SOUTHERN
COASTAL PLAIN. GIVEN A SLIGHTLY STRONGER WIND FIELD WITH FAIRLY
UNIDIRECTIONAL WESTERLY DEEP LAYER SHEAR AROUND 20 KNOTS...EXPECT
CONVECTIVE ELEMENTS TO DEVELOP INTO LINE SEGMENTS AND CLUSTERS.

THE FRONT IS EXPECTED TO SLOWLY DROP SOUTH AND EAST OVERNIGHT
APPROACHING THE SOUTH CAROLINA BORDER BY DAYBREAK. A DRIER AND
LESS UNSTABLE AIR MASS WILL MOVE INTO AREA LATE TONIGHT ALLOWING
PRECIPITATION TO DIMINISH FROM NORTHWEST TO SOUTHEAST AND SKIES TO
PARTIALLY CLEAR. OVERNIGHT LOWS IN THE 68 TO 74 RANGE LOOK GOOD.
-BLAES

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
AS OF 230 PM THURSDAY...

SHORT TERM MODEL IN DECENT AGREEMENT IN THEIR DEPICTION OF A
SURFACE-850MB BOUNDARY EXITING THE SOUTHERN COUNTIES AROUND
DAYBREAK FRIDAY. N-NORTHEAST FLOW BEHIND THE LOW LEVEL BOUNDARY
WILL GRADUALLY USHER IN DRIER MORE STABLE AIR INTO THE REGION
FRIDAY INTO FRIDAY NIGHT. POSITION/ORIENTATION OF THE SURFACE TO
850 MILLIBAR HIGH SHOULD KEEP STABLE AIR MASS OVERHEAD...LIMITING
CONVECTIVE DEVELOPMENT. LOW LEVEL THICKNESSES IN THE 1425 TO 1430
METER RANGE UNDER FULL SUN TRANSLATE TO MAXIMUM TEMPERATURES IN
THE 90 TO 95 DEGREE RANGE. UNDER MOSTLY CLEAR SKIES FRIDAY
NIGHT....EXPECT MINIMUM TEMPERATURES IN THE UPPER 60S TO LOWER
70S.

SATURDAY AND SATURDAY NIGHT...GFS QUICKLY DIMINISHES/SCOOTS
EASTWARD THE MID/UPPER LEVEL RIDGE...ALLOWING MOISTURE TO
RAPIDLY RETURN INTO CENTRAL NORTH CAROLINA BY SATURDAY AFTERNOON.
MEANWHILE ...NAM-WRF/SREF/ECMWF/GEM HOLD ONTO THE MID/UPPER LEVEL
RIDGE THROUGH SATURDAY AFTERNOON THEN LOWER HEIGHTS ACROSS THE
REGION SATURDAY NIGHT IN ADVANCE OF A SHORT WAVE CROSSING THE
LOWER GREAT LAKES. SINCE GFS HAS A TENDENCY TO BREAKDOWN EAST
COAST RIDGES TOO QUICKLY...WILL FAVOR THE NAM/GEM/ECMWF SOLUTION
WITH A SLOWER MOISTURE RETURN. LINGERING RIDGE ALOFT SHOULD
MAINTAIN MOSTLY SUNNY TO PARTLY CLOUDY SKIES WITH CLOUD COVERAGE
(STILL LESS THAN 50 PERCENT) MORE PROMINENT WEST VERSUS EAST. LOW
LEVEL THICKNESSES CHANGE LITTLE FROM FRIDAY SO EXPECT COMPARABLE
MAXIMUM TEMPERATURES.

RETURN FLOW SATURDAY NIGHT WILL HAVE A UPSLOPE COMPONENT. THIS
SHOULD CAUSE LOW STRATUS TO DEVELOP LATE SATURDAY NIGHT ALONG THE
FOOTHILLS THEN SPREAD EAST INTO THE WESTERN PIEDMONT. MOISTURE
APPEARS TOO SHALLOW TO GENERATE PRECIPITATION. MINIMUM
TEMPERATURES IN THE SOUTH AND WEST SHOULD BE A TAD WARMER THAN
FRIDAY NIGHT DUE TO DEVELOPMENT OF LOW CLOUDS.

SUNDAY...APPROACH OF MID LEVEL TROUGH AND INCREASING MOISTURE
ADVECTION SHOULD RESULT IN MORE CLOUD COVERAGE AND AN INCREASING
THREAT FOR A FEW SHOWERS AND THUNDERSTORMS IN THE WEST SUNDAY
AFTERNOON. MORE CLOUDS IN THE WEST WILL LIMIT INSOLATION LEADING
TO MAXIMUM TEMPERATURES NOT AS HOT AS PREVIOUS DAYS. EXPECT SOME
PARTIAL SUN IN THE EAST TO WARM TEMPERATURES TO LEVELS AT OR ABOVE
90 DEGREES ONCE AGAIN. IF CLOUDS THICKER OR MORE WIDESPREAD THAN
FORECAST...MAXIMUM TEMPERATURES MAY END UP 2 TO 3 DEGREES COOLER.

OF NOTE...THE GFS MAINTAINS A MID LEVEL CIRCULATION THAT ONCE WAS
TROPICAL DEPRESSION FIVE (WHICH HAS BEEN HANGING AROUND THE DEEP
SOUTH FOR AT LEAST TWO WEEKS) AND TRAVERSES IT NORTHEAST INTO
CENTRAL NORTH CAROLINA SUNDAY. OTHER MODEL GUIDANCE WASHES OUT
THIS FEATURE OR HAS A SLOWER/WEAKER SOLUTION. THIS REMNANT
CIRCULATION WILL NEED TO BE MONITORED FRIDAY THROUGH SATURDAY AS
MOISTURE ASSOCIATED WITH THIS FEATURE MAY ENHANCE CONVECTIVE
COVERAGE SUNDAY INTO SUNDAY NIGHT. IF THE GFS IS ONTO
SOMETHING...THEN POPS WOULD NEED TO BE INCREASED DRAMATICALLY
SATURDAY NIGHT INTO SUNDAY.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AS OF 200 PM THURSDAY...

SOME DISAGREEMENT IN THE MODELS THIS PERIOD. FAIRLY STRONG UPPER
RIDGE WILL INITIALLY EXTEND SOUTHWEST TO NORTHEAST FROM THE DESERT
SOUTHWEST TO THE WESTERN GREAT LAKES. THIS FEATURE WILL AID TO
DIG A L/W TROUGH FROM NEW ENGLAND SOUTHWARD TO THE CAROLINAS. THE
ATTENDANT SURFACE BOUNDARY WILL AID TO FOCUS MOISTURE AND
LIFT...LEADING TO A CHANCE OF SHOWERS AND THUNDERSTORMS ACROSS THE
REGION SUNDAY NIGHT THROUGH MONDAY.

MODEL DISCREPANCIES MORE EVIDENT TUESDAY AS ECMWF DEVELOPS A
CLOSED UPPER LOW IN VICINITY OF THE DELMARVA WHILE THE GFS AND
CANADIAN REMAIN PROGRESSIVE WITH THE UPPER TROUGH. THE ECMWF
SOLUTION WOULD MAINTAIN A CONFLUENT CYCLONIC FLOW OVER THE
NORTHEAST SECTOR OF THE CWA RESULTING IN CHANCE POPS TUESDAY
THROUGH WEDNESDAY. THE GFS/CANADIAN SOLUTION WOULD RESULT IN DRIER
MORE STABLE AIR IN ANTICYCLONIC FLOW PATTERN...LIMITING POPS.
BASED ON RECENT HISTORY WITH THE ECMWF OUTPERFORMING THE
GFS...WILL LEAN TOWARD THE ECMWF SOLUTION FOR NOW.
STILL...GREATEST THREAT FOR CONVECTION WILL BE SUNDAY NIGHT
THROUGH MONDAY WITH THE PASSAGE OF THE LEAD SURFACE BOUNDARY AND
UPPER SUPPORT.

REGARDLESS OF WHICH MODEL SOLUTION VERIFIES...MAXIMUM TEMPERATURES
ACROSS THE REGION THROUGH THIS PERIOD WILL AVERAGE CLOSE TO
NORMAL. PER ECMWF...CLOUDS AND LIGHT NORTH TO NORTHEAST FLOW WOULD
MAINTAIN A WEAK 850 MILLIBAR THERMAL TROUGH OVER THE REGION
THROUGH MUCH OF THE PERIOD. THIS TYPE OF PATTERN USUALLY RESULTS
IN NEAR OR SLIGHTLY BELOW NORMAL TEMPERATURES. GFS/CANADIAN
SUPPORT A LOW LEVEL EASTERLY FLOW WHICH USUALLY RESULTS IN NEAR
NORMAL TEMPERATURES.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
AS OF 810 PM...

MODERATE TO HEAVY RAINS CLEARING THE AREAS NORTH OF HIGHWAY 64 AT
THIS TIME WITH A FEW WEAKENING SHOWERS LEFT OVER. TO THE SOUTH A
FEW THUNDERSTORMS WILL PRODUCE HEAVY RAINS WITH REDUCED
VISIBILITIES AND BRIEF IFR CEILINGS. THESE STORMS WILL CLEAR FROM
WEST TO EAST THIS EVENING... EXITING AREAS JUST EAST OF
FAYETTEVILLE NEAR MIDNIGHT.

SOME FOG EXPECTED LATER TONIGHT... WITH LOW STRATUS MOST LIKELY
EAST AND SOUTH OF THE TRIAD (NORTHWEST PIEDMONT). STRATUS IS NOT
FORECAST TO PERSIST MUCH PAST SUNRISE... THEN VFR CONDITIONS
EXPECTED FOR THE REMAINDER OF THE TAF PERIOD.

FAIR WEATHER WITH VFR CONDITIONS ON FRIDAY AFTERNOON WILL PERSIST
INTO SUNDAY AS HIGH PRESSURE DOMINATES THE WEATHER ACROSS THE
REGION. SOME MORNING FOG OR STRATUS IS POSSIBLE SUNDAY AND MONDAY.
ADVERSE AVIATION ARE POSSIBLE ON MONDAY AS THE NEXT APPROACHES
FROM THE NORTHWEST.
