AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
201 AM EST FRI NOV 11 2011
.SYNOPSIS...
COOL AND BREEZY CONDITIONS CAN BE EXPECTED TODAY AS HIGH PRESSURE
BUILDS INTO THE REGION. THE HIGH WILL SETTLE OVERHEAD LATE TONIGHT
UNDER CLEAR SKIES...ALLOWING TEMPERATURES BY DAYBREAK SATURDAY TO
DIP INTO THE UPPER 20S TO LOWER 30S ACROSS MOST INLAND LOCATIONS.
TEMPERATURES WILL WARM THROUGH EARLY NEXT WEEK AS THE HIGH MOVES
OFFSHORE. ANOTHER COLD FRONT WILL SWEEP ACROSS THE AREA THURSDAY.
&&
.NEAR TERM /THROUGH TONIGHT/...
AS OF 200 AM SATURDAY...BRISK CONDITIONS ACCOMPANIED BY SUNSHINE
ON TAP TODAY AS COLD AIR ADVECTION SWEEPS ACROSS THE REGION. AN
UPPER TROUGH AXIS IS PRESENTLY CROSSING OUR FORECAST AREA BOUND
FOR MID-ATLANTIC WATERS BY AFTERNOON. CLEARING ALREADY UNDERWAY
AND WE WILL WITNESS PLUMMETING DEWPOINTS TODAY AS VERY DRY MOVES
THROUGH. WE COULD SEE INTERIOR LOCATIONS OF SC FLIRT WITH THE 60
DEGREE MARK BY MID AFTERNOON...BUT MOST LOCATIONS WILL TOP-OUT
ONLY IN THE MID TO UPPER 50S TODAY.
NEAR PERFECT LONG-WAVE RADIATION ESCAPE TONIGHT AS HIGH PRESSURE
SETTLES OVERHEAD AMID A CLEAR DOME. THIS WILL RESULT IN WIDE
SPREAD FREEZING TEMPERATURES INLAND. FOR THIS REASON THE FREEZE
WATCH HAS BEEN UPGRADED TO A WARNING FOR INLAND AREAS THAT ARE
AGRICULTURALLY SUSCEPTIBLE TO A FREEZE RIGHT NOW. ALSO INCLUDED
COASTAL PENDER DUE TO COLD AIR DRAINAGE FROM THE HOLLY SHELTER
GAME-LAND. THE REMAINDER OF OUR COASTAL STRIP A FROST ADVISORY
HAS BEEN INTRODUCED FOR LOW/MID 30S EARLY SATURDAY MORNING.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 2 AM FRIDAY...SURFACE HIGH PRESSURE RIGHT OVER THE
REGION ON SATURDAY WHILE MID LEVEL FLOW IS ZONAL/WESTERLY. EXPECT
FULL SUNSHINE BUT THE PROXIMITY OF THE HIGH WILL MEAN SHALLOW MIXING
AND TEMPERATURES WILL BE A FEW DEGREES BELOW NORMAL. AS THE SURFACE
RIDGE SHIFTS OFFSHORE SATURDAY NIGHT JUST ENOUGH RETURN FLOW WILL BE
JUST ENOUGH TO KEEP TEMPERATURES FROM GETTING AS COLD AS FRIDAY
NIGHT BY PREVENTING RADIATIONAL COOLING CONDITIONS FROM BEING
OPTIMIZED AS SKY OTHERWISE STAYS CLEAR. RETURN FLOW CONTINUES ON
SUNDAY BUT REMAINS VERY LIGHT AS RIDGE AXIS REMAINS ALONG THE SE
COAST INTO FLORIDA WHILE MID LVL HIGH DEVELOPS OVER GOMEX. ALTHOUGH
BOTH WILL HAVE ONLY A PERIPHERAL EFFECT ON THE REGION WE WILL STILL
WARM UP TO 70 IN MOST PLACES SUNDAY PM. MOISTURE ADVECTION JOINS IN
WITH THE WARM ADVECTION SUNDAY NIGHT. THIS SHOULD BRING MILD
CONDITIONS WITH LOWS IN THE 50S.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
AS OF 2 AM FRIDAY...VERY LOW AMPLITUDE MID LEVEL RIDGING WILL
PERSIST MONDAY AND TUESDAY OVER THE GOMEX INTO THE BAHAMAS.
MEANWHILE BROAD TROUGHINESS WILL COVER MUCH OF THE NORTHERN HALF OF
THE NATION. THE LEADING EDGE OF THE CYCLONIC CURVATURE MAY PRESS A
COLD FRONT INTO THE CAROLINAS SOME TIME TUESDAY AS THE AFOREMENTIONED
UPPER RIDGE INCREASES SHARPLY IN AMPLITUDE OFF THE EAST COAST. THE
LONGITUDE AT WHICH THIS OCCURS IS A LITTLE UNCERTAIN AND IT MAY HAVE
LARGE RAMIFICATIONS FOR THE LATTER PART OF THE PERIOD. INITIALLY
SOME VERY WARM READINGS ARE EXPECTED AND SOME INLAND LOCALES COULD
FLIRT WITH 80 DEGREES. IF THE RIDGE AXIS IS FAR ENOUGH EAST THEN WE
MAY BE LOOKING AT A FROPA AROUND TUESDAY AS PREVIOUSLY THOUGHT. 00Z
GFS RUN HAS THE RIDGE BUILD A LITTLE FURTHER WEST CLOSER TO THE US
SLOWING THE PROGRESS OF THE FRONT. GIVEN THE WARMTH THAT WILL BE IN
PLACE THIS IDEA SEEMS PLAUSIBLE AND THIS SLOWING TREND MAY EVEN
CONTINUE IN FUTURE GUIDANCE RUNS.
&&
.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
AS OF 06Z...HIGH CONFIDENCE IN VFR THROUGH THE VALID PERIOD WITH
IMPROVING CIGS. GUSTY NW WINDS LIKELY MUCH OF FRIDAY.
COLD FRONT HAS MOVED WELL OFFSHORE...AND STRONG DRY AIR ADVECTION
ONGOING ATTM. SKY CONDITIONS HAVE IMPROVED TO SKC INLAND...WITH JUST
A FEW/SCT REMNANT STRATOCU LEFT ACROSS THE COAST. THIS WILL BE THE
CASE THROUGH THE NIGHT AS NW WINDS CONTINUALLY DRY THE
COLUMN...IMPROVING ALL SKY CONDITIONS TO SKC BY MORNING.
NW WINDS WILL RAPIDLY BECOME GUSTY AFTER SUNRISE. EXPECT WIND SPEEDS
OF 10-15 KTS...GUSTING UP TO 25 KTS AT TIMES...ESPECIALLY EARLY IN
THE DAY. WINDS WILL SLOWLY EASE THROUGH THE EVE AS HIGH PRESSURE
MOVES TOWARDS THE AREA REDUCING THE PG. WINDS WILL THEN BECOME
NEARLY CALM AFTER SUNSET BENEATH THE NOCTURNAL INVERSION...BUT NO
FOG WILL DEVELOP DUE TO THE DRYNESS OF THE AIR MASS.
EXTENDED OUTLOOK...VFR THROUGH THE EXTENDED OTHER THAN POSSIBLE FOG
MONDAY AND TUESDAY MORNINGS.
&&
.MARINE...
NEAR TERM/THOUGH TONIGHT/...
AS OF 200 AM SATURDAY...SMALL CRAFT ADVISORY REMAINS HOISTED
THROUGH MORNING BECAUSE OF 25 KNOT NW WIND GUSTS. WINDS WILL EASE
IN THE AFTERNOON...BECOMING NEARLY CALM LATE TONIGHT AS SURFACE
HIGH PRESSURE MOVES OVERHEAD. THUS IT APPEARS ADVISORIES WILL
EXPIRE LATER TODAY AS THE SEA SETTLES DOWN A BIT. IMPROVEMENT WILL
BE FASTEST NEAR SHORE TODAY...AREA-WIDE TONIGHT. THE OCEAN WILL BE
MARKED BY NW WIND WAVES INTERACTING WITH RESIDUAL BUT DAMPENING
EASTERLY WAVES TODAY...BUMPIEST THIS MORNING DUE TO WINDS. HUGE
IMPROVEMENT OVERNIGHT...AS WINDS DIE...LEAVING GLASSY SEAS AND
RESIDUAL E WAVES OF 2-3 FEET IN 11 SECOND INTERVALS.
SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 2 AM FRIDAY...SOME QUIET WEATHER ON TAP FOR THE SHORT TERM
PERIOD. HIGH PRESSURE CENTERED JUST OFF THE COAST SATURDAY MORNING
WITH JUST A SLOW EASTWARD DRIFT AS THE AFTERNOON WEARS ON. AS THIS
TREND CONTINUES A WEAK SOUTHERLY COMPONENT WILL BECOME ESTABLISHED
DURING THE OVERNIGHT HOURS. THE CENTER OF THE HIGH WILL BE LOCATED
EVEN FURTHER TO THE EAST BY SUNDAY BUT A RIDGE AXIS WILL STILL
EXTEND BACK INTO THE SOUTHEASTERN U.S. AND NORTHERN FLORIDA.
SOUTHERLY WINDS WILL THUS REMAIN VERY LIGHT...10 KT OR LESS FOR THE
MOST PART. THE END OF THE PERIOD MAY BRING AN INCREASE IN GRADIENT
AS THIS RIDGE AXIS WEAKENS AND RETREATS. IF SO THEN SEAS WILL BEGIN
TO BUILD...OTHERWISE THEY WILL REMAIN IN THE 2 TO 3 FT RANGE FOR THE
REMAINDER OF THE PERIOD. A SMALL SWELL COMPONENT WILL START TO BE
INTRODUCE LATE IN THE PERIOD ALONG WITH THE WIND WAVES.
LONG TERM /MONDAY THROUGH TUESDAY/...
AS OF 2 AM FRIDAY...A RETURN FLOW OF SOUTH TO SOUTHWESTERLY WINDS
IS EXPECTED FOR THE DURATION OF THE LONG TERM AS HIGH PRESSURE
REMAINS ANCHORED ACROSS THE WEST ATLANTIC. SEAS WILL BE 2 TO 4 FT
FOR THE MOST PART WITH BOTH A WIND WAVE COMPONENT AND SOME SWELL
ENERGY FROM THE ESE DUE TO A LONG FETCH INTO THE BAHAMAS.
&&
.FIRE WEATHER...
AS OF 200 AM FRIDAY...MIN RH VALUES TO BOTTOM OUT BTWN 23-29
PERCENT THIS AFTERNOON. GUSTY NW WINDS OF 15-25 MPH THIS MORNING
WILL EASE TO 10 TO 20 MPH THIS AFTERNOON. THIS WILL FALL SHORT OF
RED FLAG CRITERIA...BUT WILL STILL RESULT IN AN ELEVATED FIRE
DANGER TODAY...PRIMARILY OF FINE AND LEAF-TYPE FUELS. WITH THIS IN
MIND WILL INSERT ELEVATED FIRE DANGER HEADLINE INTO THE FIRE
WEATHER FORECAST THIS MORNING. IDEAL RADIATIONAL COOLING TONIGHT
WILL FOSTER GOOD RH RECOVERIES...70-80 PERCENT DAYBREAK SATURDAY.
