Area forecast discussion, Aug 11, 3:05 PM EDT, 10 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
305 PM EDT SAT AUG 11 2012

.SYNOPSIS...
AN APPROACHING AND SLOW MOVING COLD FRONT WILL BRING A GOOD CHANCE
OF SHOWERS AND THUNDERSTORMS THROUGH EARLY SUNDAY...BEFORE TAPERING
OFF LATE IN THE WEEKEND AS DRIER AIR MOVES IN FROM THE WEST. FAIR
CONDITIONS ARE EXPECTED MONDAY AND TUESDAY...FOLLOWED BY A CHANCE
OF SHOWERS LATE TUESDAY AFTERNOON THROUGH EARLY WEDNESDAY...AS A
WEAK COLD FRONT SWEEPS ACROSS THE AREA. DRY WEATHER IS EXPECTED
LATE IN THE WEEK...BUT A COLD FRONT IS MAY APPROACH NEXT WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 3 PM SATURDAY...MAIN FORECAST DILEMMA WILL BE POPS MAINLY
FOR THE OVERNIGHT HOURS AS THE GFS AND TO SOME EXTENT THE NAM ARE
BULLISH ON THE SYNOPTIC SCENARIO. IT APPEARS THE MAIN 200MB JET
ROTATES PERFECTLY ACROSS THE REGION FOR RIGHT ENTRANCE REGION
DYNAMICS AND WITH WATER VAPOR IMAGERY SHOWING A MOISTURE LADEN
ATMOSPHERIC RIVER...CATEGORICAL POPS SEEM LIKE A LOGICAL CHOICE.
THIS FEATURE APPEARS TO BE THE CATALYST FOR THE CONVECTION
CURRENTLY ALONG THE GULF COAST. WILL NOWCAST THE NEXT FEW
HOURS...THEN A MORE GENERALLY 80-90 POP FOR THE OVERNIGHT EARLY
MORNING HOURS. MAINTAINED A STRATEGY OF GOING SLIGHTLY WARMER THAN
GUIDANCE FOR LOW TEMPERATURES.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
AS OF 3 PM SATURDAY...SUNDAY WE WILL STILL BE DEALING WITH A
SLUGGISH MOVING COLD FRONT CHUGGING LAZILY WEST TO EAST ACROSS
OUR FORECAST AREA...WHICH WEAKENS AND LIFTS NORTH OF OUR ZONES
BY SUNDAY NIGHT. BEFORE THIS OCCURS HOWEVER...IT APPEARS THAT
A SHARP DRYING TREND ALOFT WILL COMMENCE SUNDAY AFTERNOON AS
THE UPPER TROUGH OVER THE REGION LIFTS NORTH AND DE-AMPLIFIES.
AS A RESULT...POP VALUES WILL CURTAIL TO ISOLATED THROUGH SUNDAY
AFTERNOON...DRYING FROM WEST TO EAST WITH LINGERING ISOLATED
CONVECTION ALONG THE COAST TOWARD EVENING...PULLING OFFSHORE
OVERNIGHT.

MONDAY FAIR CONDITIONS ARE ANTICIPATED AS SFC DEWPOINTS LOWER
AND DRY AIR PERCHED ABOVE 6000 FEET HOLDS INTACT...VIA DRY
WESTERLY WIND-FLOW ALOFT. MONDAY LOOKS TO BE THE WARMER DAY BY
VIRTUE OF CLOUDS AND LOCALIZED RAIN-COOLED AIR STREWN ABOUT THE
WARNING AREA SUNDAY.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
AS OF 3 PM SATURDAY...LONG TERM PERIOD WILL BE CHARACTERIZED BY A
PERSISTENT EAST COAST TROUGH AND RIDGING ACROSS THE FOUR CORNERS
REGION. AT THE SURFACE...A COLD FRONT WILL MOVE ACROSS THE AREA
WEDNESDAY AND DISSIPATE FOLLOWED BY WHAT APPEARS TO BE A STRONGER
FRONT FOR THE WEEKEND. HIGHEST POPS FOR THE PERIOD ARE ASSOCIATED
WITH THE AFOREMENTIONED SURFACE FEATURES...EARLY WEDNESDAY AND
SATURDAY. REGARDING TEMPERATURES...FRIDAY...WITH THE WESTERLY
DOWNSLOPE FLOW LOOKS LIKE THE WARMEST DAY SOMEWHAT ABOVE CLIMATOLOGY
WITH THE REMAINDER OF THE PERIOD NEAR SEASONAL NORMALS.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
AS OF 19Z...SCATTERED SHOWERS AND THUNDERSTORMS ARE AFFECTING THE
AREA AT THE TIME AND STAND A REASONABLE CHANCE OF AFFECTING ALL
TERMINALS IN SOME FASHION DURING THE FIRST 6 HOURS OF THE PERIOD.
THE STORMS WILL BE ACCOMPANIED BY MFR OR SHORT DURATION IFR
CONDITIONS. OUTSIDE STORMS...S TO SW WINDS OF 10 TO 15 KT WILL
DIMINISH TO 5 TO 10 KT LATE THIS AFTERNOON AND BECOME SW TONIGHT.
COULD SEE LINGERING SHOWERS AND STORMS AFTER 03Z...MAINLY OVER THE
COASTAL TERMINALS.

EXTENDED OUTLOOK...VFR MONDAY THROUGH THU...OUTSIDE POSSIBLE SHOWERS
AND STORMS TUESDAY NIGHT INTO WED.

&&

.MARINE...

NEAR TERM /THROUGH TONIGHT/...
AS OF 3 PM SATURDAY...LOW LEVEL WIND FIELDS HAVE COME IN A TAD
STRONGER WITH THE 1200 UTC GUIDANCE. EXPECT A SOUTHERLY FLOW OF
10-15 KNOTS TO INCREASE TO 15-20 KNOTS BY LATE TONIGHT AND VEER TO
THE SOUTHWEST AS SEA BREEZE INFLUENCES ARE LOST. DO NOT EXPECT A
SIGNIFICANT WIND SHIFT AS THE FRONT REMAINS WELL OFF TO THE WEST.
SEAS STILL HOVERING AROUND FIVE FEET AT 41013 AND 41110. WILL
RAISE A SCEC FOR THE NORTHERN WATERS.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
AS OF 3 PM SATURDAY...NO SIGNIFICANT HAZARDS EXPECTED SUNDAY AND
MONDAY ALTHOUGH A FEW TSTMS MAY IMPACT THE 0-20NM WATERS SUNDAY
AS A WEAKENING COLD INLAND OVER THE COASTAL INTERIOR PROVIDES A
FOCUS FOR SHOWERS OR A FEW STORMS. SINCE THE FRONT IS WEAK AND
DISSIPATES NORTH OF THE WATERS...S-SW WIND FLOW WILL REMAIN OVER
THE WATERS...BUT WELL BELOW ADVISORY CRITERIA. SEA SPECTRUM SUNDAY
MAINLY S WAVES 3-4 FEET AT 6 SECONDS...AND SE WAVES 1-2 FEET AT
8-9 SECONDS. MONDAY  SIMILAR BUT IMPROVED AS THE S WAVES SUBSIDE
TO AROUND 2 FEET.

LONG TERM /TUESDAY THROUGH THURSDAY/...
AS OF 3 PM SATURDAY...SOUTHWEST FLOW THROUGH THE PERIOD.
STRONGEST WINDS OCCUR LATER TUESDAY AHEAD OF THE NEXT SYSTEM.
EXPECT 15-20 KNOTS BRIEFLY AT THIS TIME. OTHERWISE 10-15 KNOTS AND
PROBABLY CLOSER TO TEN WILL SUFFICE. RELATIVELY BENIGN WINDS AND
SEAS FOR WEDNESDAY AND THURSDAY. SEAS REMAIN VOID OF ANY
SIGNIFICANT SWELL AS THE RECENTLY OBSERVED INCREASE IN TROPICAL
ACTIVITY IN THE ATLANTIC BASIN HAS ALL BUT DISSIPATED.
