AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
238 PM EDT THU MAY 3 2007

.SYNOPSIS...
AN UPPER LEVEL SHEAR AXIS EXTENDED WEST TO EAST... FROM KANSAS
THROUGH MO... KY... AND INTO VA THURSDAY AFTERNOON. UPPER RIDGING
CONTINUED OVER THE SOUTHEASTERN U.S. INTO THE OHIO VALLEY WITH A CUT
OFF LOW AT H5 OVER N TEXAS. THE MAIN SURFACE FRONT HAD PUSHED SOUTH
OF CENTRAL NC... TO THE SE COASTAL AREA OF NC. A SECONDARY PUSH OF
COOLER STABLE AIR WAS ADVANCING S-SW THROUGH THE SANDHILLS AND
SOUTHERN COASTAL PLAIN AT EARLY AFTERNOON... DRIVEN BY A 1026 MB
HIGH CENTERED OVER THE EASTERN GREAT LAKES.
&&

.SHORT TERM /TONIGHT THROUGH SUNDAY/...
WIDESPREAD LOW CEILINGS HAVE BEEN SPREADING S-SW FROM NORTHERN
SECTIONS OF THE STATE INTO THE CENTRAL AND EASTERN SECTIONS BEHIND
THE SECONDARY COLD FRONT. THE TEMPERATURES FELL 4-5 DEGREES IN AN
HOUR ACROSS THE PIEDMONT (RDU AND GSO) AS THIS COLD FRONT PASSED
LATE MORNING INTO THE EARLY AFTERNOON. AS OF EARLY AFTERNOON... THE
TEMPERATURES TO THE NORTH HAVE BEEN HOLDING BETWEEN 60-63 WITH THE
LOW OVERCAST AND NE BREEZE... WHILE READINGS DOWN SOUTH AT
WADESBORO... ROCKINGHAM... AND LAURINBURG HAD REACHED 80-82 WITH
MOSTLY SUNNY SKIES. ORGANIZED SHOWERS REMAINED TO OUR
NORTHWEST-NORTH ALONG THE OLD H5 SHEAR AXIS EXTENDING FROM KY EAST
ACROSS SOUTHERN VA.

FOR THE REMAINDER OF THE AFTERNOON... THE SHEAR AXIS WILL REMAIN TO
OUR NORTH AND THIS IS WHERE THE BEST CHANCE OF SIGNIFICANT SHOWERS
AND ISOLATED ELEVATED THUNDERSTORMS WILL REMAIN. WE WILL MAINTAIN A
CHANCE POP FOR THE NORTHERN COUNTIES AS THERE COULD BE A FEW SHOWERS
THAT CLIP OUR BORDER COUNTIES. THE LOW LEVEL CLOUDINESS WILL
CONTINUE TO SPREAD SOUTH WITH THE COLD FRONT THAT SHOULD REACH THE
SOUTHERN BORDER COUNTIES DURING THE MID TO LATE AFTERNOON. THE TEMPS
WILL LIKELY FALL 5-7 DEGREES IN AN HOUR AS THE FRONT PASSES...
ESPECIALLY WHERE READINGS WERE IN THE 80S AT EARLY AFTERNOON.

WITH THE SURFACE WINDS ALREADY FROM THE NE... ADVECTING MORE STABLE
BOUNDARY LAYER INTO THE REGION... THE CHANCE OF SHOWERS OR
THUNDERSTORMS THIS AFTERNOON AHEAD OF THE BOUNDARY APPEARS RATHER
SMALL. THE LACK OF UPPER SUPPORT... INSTABILITY...AND SURFACE
CONVERGENCE SUPPORTS ONLY ABOUT A 10 POP.

FOR THE OVERNIGHT PERIOD... THE CHANCE OF MUCH NEEDED RAIN WILL BE
ON THE INCREASE ESPECIALLY IN THE NW EARLY... THEN ELSEWHERE DURING
THE LATE EVENING AND OVERNIGHT. THE H5 SHEAR AXIS TO OUR NORTH IS
EXPECTED TO SLOWLY DRIFT SOUTH TOWARD NORTHERN NC. THE REGION IS
FORECAST TO COME UNDER THE INFLUENCE OF THE LEFT EXIT REGION OF THE
H2 JET... WHICH SHOULD WORK IN CONJUNCTION WITH WAA AND ISENTROPIC
LIFT IN THE 925-850 MB LAYER... TO PRODUCE SIGNIFICANT LIFT. POP
WILL BE RAISED CATEGORICAL NORTH... WITH LIKELY SE-S.

THE BOUNDARY LAYER WILL BE INCREASINGLY STABLE AS THE UPPER 40S AND
LOWER 50S DEW POINTS CONTINUE TO ADVECT IN FROM THE NE. THEREFORE...
THE 12Z GFS QPF CONVECTIVE LOOKING BULLS EYE OVER NORTHERN AND
EASTERN NC OVERNIGHT INTO FRIDAY APPEARS WAY OVERDONE. THE 12Z NAM
QPF IS MUCH LIGHTER 0.10 TO 0.25 OF AN INCH... AND APPEARS VERY
REASONABLE GIVEN THE AFOREMENTIONED PATTERN. THE MAXIMUM QPF MAY
VERY WELL BE IN THE NW... WHERE THE WAA PATTERN AND LIFT OF THE
DEEPEST MOISTURE IS ENHANCED BY THE INCREASINGLY UPSLOPE FLOW.
TOTALS SHOULD BE LESS ACROSS THE SOUTHERN PIEDMONT. LOWS TONIGHT
WILL DIP INTO THE 50S (NEAR 50 NE TO MID 50S SW).

RAIN CHANCES WILL LINGER INTO EARLY FRIDAY DUE TO THE AFOREMENTIONED
UPPER LEVEL ENERGY. WILL CONTINUE TO LEAVE OUT POP FRIDAY NIGHT AND
EARLY SATURDAY DUE TO THE BUILDING UPPER RIDGE AND LACK OF UPGLIDE
ABOVE THE LOW LEVEL COOL STABLE DOME. IT WILL REMAIN CLOUDY AND COOL
FRIDAY WITH SOME HIGHS EXPECTED TO REMAIN IN THE UPPER 50S NORTH.
MOST AREAS WILL SEE ONLY 60S. THERE MAY BE SOME BREAKS IN THE CLOUDS
SATURDAY... BUT POP SHOULD INCREASE AGAIN DURING THE DAY. THE
CURRENT UPPER LOW OVER TEXAS IS FORECAST TO MOVE NE TOWARD KY BY
EARLY SATURDAY... THE SHEAR OUT OVER VA/NC LATER SATURDAY AND
SATURDAY NIGHT. SINCE CENTRAL NC WILL STILL BE UNDER THE INFLUENCE
OF THE COOL STABLE DOME... WE WILL LEAVE OUT THUNDER CHANCE FOR NOW.
WE WILL INSERT CHANCE (30-50 POP FOR SATURDAY AFTERNOON THROUGH
SATURDAY NIGHT). LOWS SATURDAY GENERALLY 50-55... HIGHS SATURDAY
SHOULD REMAIN IN THE 60S NW-N RANGING TO THE MID 70S SE.

DEFINITIVE DRYING IS FORECAST TO ARRIVE FROM THE NORTH SUNDAY. THE
UPPER LEVEL SHEAR AXIS SHOULD GET PUSHED SOUTH QUICKLY AS A H5
TROUGH DEVELOPS IN THE WESTERN ATLANTIC. EXPECT CLEARING SKIES AND
WARMER TEMPS... EVEN THROUGH A 1030+ MB SURFACE HIGH SHOULD BEGIN TO
EXTEND DOWN INTO NC FROM EASTERN CANADA. HIGHS SHOULD REBOUND INTO
THE LOWER TO MID 70S.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
STRONG MID/UPPER LEVEL RIDGING OVER THE MISSISSIPPI VALLEY AND
SUBSEQUENT SURFACE RIDGING ALONG THE EAST COAST WILL DOMINATE THE
EXTENDED PERIOD. HIGH TEMPERATURES WILL WARM FROM THE MID TO UPPER
70S ON MONDAY TO THE MID 80S ON WEDNESDAY... UNDER MOSTLY
SUNNY/CLEAR SKIES.  DIURNAL CUMULUS AND PERIODS OF MID/ HIGH CLOUDS
WILL BECOME MORE PREVALENT WEDNESDAY AND ESPECIALLY THURSDAY... AS
BOTH NEAR SURFACE AND ALOFT MOISTURE INCREASES AHEAD OF A MID LEVEL
TROUGH APPROACHING FROM THE CENTRAL UNITED STATES. HIGHS THURSDAY A
TOUCH COOLER AS HEIGHTS ALOFT DECREASE... HIGHS AROUND 80 DEGREES.
LOWS THROUGH THE PERIOD INCREASING A FEW DEGREES EACH MORNING FROM
AROUND 50 DEGREES MONDAY MORNING TO THE LOWER 60S BY THURSDAY
MORNING. -MWS
&&

.AVIATION /19Z-18Z/...
MOISTURE IS TRAPPED AND WILL CONTINUE TO POOL IN NORTHEAST FLOW
BENEATH A COLD AIR DAMMING WEDGE INVERSION THROUGH FRIDAY... WHICH
WILL RESULT IN MVFR TO IFR CEILINGS AND VISIBILITIES AT THE
TERMINALS THROUGHOUT THE TAF PERIOD. CEILINGS WILL BRIEFLY INCREASE
INTO MVFR RANGE THIS AFTERNOON... AS SLIGHTLY DRIER NEAR SURFACE AIR
ADVECTS INTO SOUTHWESTWARD FROM VIRGINIA AND NORTHEASTERN NORTH
CAROLINA. A COMBINATION OF LOW LEVEL WARM ADVECTION/ISENTROPIC LIFT
IN THE 290-300 K LAYER... AND A DECREASE IN SURFACE TEMPERATURES AND
RESULTANT DECREASE IN NEAR SURFACE DEWPOINT DEPRESSIONS... WILL
RESULT IN CEILINGS LOWERING INTO IFR RANGE AFTER SUNSET. THE CHANCE
OF LIGHT RAIN WILL INCREASE OVERNIGHT FROM WEST TO EAST AS SLOPED
ASCENT INTO THE LEFT EXIT REGION OF A 200 MILLIBAR NORTHWESTERLY
UPPER LEVEL JET STREAK... RESULTING IN THE AFOREMENTIONED ISENTROPIC
LIFT... INCREASES. THE LIGHT RAIN SHOULD TAPER OFF TOWARD SUNRISE...
WITH CEILINGS GRADUALLY LIFTING BACK INTO MVFR RANGE THEREAFTER. AS
AN ASIDE... SMOKE FROM THE FIRES IN SOUTHERN GEORGIA HAS CONVERGED
AND BECOME TRAPPED IN THE LOW LEVEL FRONTAL ZONE LOCATED OVER
CENTRAL SOUTH CAROLINA AND EXTREME SOUTHEASTERN NORTH CAROLINA. THIS
SMOKE LAYER WILL LIKELY CONTINUE TO REDUCE VISIBILITIES AT KFAY
THROUGH MOST OF THE TAF PERIOD... AS IT WILL REMAIN TRAPPED BENEATH
THE WEDGE INVERSION IN CONTINUED EASTERLY LOW LEVEL FLOW.  -MWS
