AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
459 PM EDT MON APR 5 2010

.SYNOPSIS...
HIGH PRESSURE WILL BE OFF THE MID ATLANTIC AND SOUTHEAST COAST
TONIGHT INTO EARLY THURSDAY...MAINTAINING DRY AND UNSEASONABLY
WARM WEATHER. A COLD FRONT APPROACHES FROM THE WEST THURSDAY THEN
PUSHES ACROSS THE AREA THURSDAY EVENING INTO FRIDAY MORNING. HIGH
PRESSURE BUILDS INTO THE REGION AGAIN LATE FRIDAY THROUGH NEXT
WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
ADDED CHCS OF SHRA/TSRA THIS AFTN/EARLY EVE TO SW THIRD OF THE
CWA WITH ASSOC VORT MAX AND FRONTAL BOUNDARY STARTING TO PUSH INTO
THE RGN. LATEST RUC ONLY ONE TO ADD PRECIP INTO THE RGN AND HAVE
FOLLOWED CLOSE TO SOLN WITH RESPECT TO POPS. POTENTIAL DOES EXIST
FOR A STORM TO REACH CLOSE TO SEVERE LIMITS (ESP FAR SW).

HIGH PRESSURE SFC AND ALOFT WILL PROVIDE A MOSTLY CLR AND MILD TO
WARM NIGHT ACROSS THE REGION. EXCEPTION WILL BE ALONG THE
DELMARVA...WHERE STLT IMAGERY INDICATES A NW/SE BAND OF LOW CLDS
HUGGING COAST. EXPECT THIS AREA OF CLDS TO SLOWLY LIFT NEWD NEXT
12 HOURS...AND GENERALLY REMAIN VERY CLOSE TO COAST. SSE LO LVL
FLOW COULD ALLOW STRATUS TO MOVE A FEW MILES INLAND ALG/N OF WAL.
HOWEVER...WILL STAY WITH STLT CURRENT TRENDS AND KEEP INLAND AREAS
GENLY CLR TNGT. HAVE ALSO ADDED PATCHY FOG TO DELMARVA AND AREAS E
OF I-95 IN VA/NE NC BASED UPON FOG DVLPMT LAST NIGHT...AND
CONTINUED MARITIME FLOW NEAR THE COAST.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
RIDGE SFC/ALOFT AMPLIFIES ACROSS THE REGION TUESDAY/WEDNESDAY WITH
VERY WARM TO HOT CONDITIONS PREVAILING. SUNNY SKIES AND GENERALLY
CLEAR NIGHTS EXPECTED THROUGH WEDNESDAY NIGHT. HAVE NOT STRAYED
FAR FROM MAX TEMPS IN EXISTING FORECAST. HOWEVER...HAVE MADE
DOWNWARD ADJUSTMENTS TO TEMPS AT WAL/OXB TOMORROW AND WEDNESDAY
DUE TO FLOW OFF OCEAN. BARELY GOT OUT OF THE 50S TODAY AT
OXB...AND ONLY MID/UPR 60S. WHILE FLOW BECOMES MORE SLY NEXT 2
DAYS...THINK TEMPS WILL REMAIN BLO GUIDANCE THROUGH WEDNESDAY.

SLY FLOW INCREASES WED AND WED NIGHT...KEEPING TEMPS QUITE WARM
FOR THIS TIME OF YEAR ALL AREAS. TEMPS WILL BE HARD PRESSED TO
DROP BELOW THE MID 60S MANY AREAS WEDNESDAY NIGHT. AMD CURRENTLY
NOT CONVINCED THAT THURSDAY WILL BE AS COOL...RELATIVELY
SPEAKING...AS GUIDANCE SUGGESTS. SO HAVE INCREASED MAX TEMPS A
COUPLE OF DEGREES ABOVE CURRENT FORECAST...WITH MOST AREAS AOA 80
DEGREES. SSW/SW LO LVL FLOW SHOULD ALLOW WARM AIR TO FINALLY GET
INTO WAL/OXB. EXPECT THERE TO BE QUITE A BIT OF SUNSHINE ON
THURSDAY...WITH ANY CHANCE FOR PRECIP WAITING UNTIL LATE IN THE
DAY...AND THEN REMAINING WEST OF I-95.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
THE MODELS ARE IN GOOD AGREEMENT OVERALL WITH THE SYNOPTIC PATTERN
SHOWING A STRONG FULL LATITUDE TROUGH SWINGING THROUGH THE
NORTHEAST FRIDAY INTO SUNDAY...BUT IT IS TRANSITORY WITH THE
RIDGING BUILDING BACK ACROSS THE SOUTHERN US AND UP INTO THE MID
ATLANTIC STATES SUNDAY INTO MONDAY. THE GFS IS STILL ABOUT 6 HOURS
FASTER THAN THE OTHER MODELS IN TIMING THE FRONT INTO THE REGION
THURSDAY NIGHT. HAVE MAINTAINED THE SLOWER TIMING BRINGING THE
FRONT ACROSS THE AREA THURSDAY NIGHT AND INCREASED POPS TO LIKELY
RANGE AND MOISTURE FEEDS NE IN ADVANCE OF THE FRONT. BUT HAVE ONLY
MENTIONED A CHANCE OF THUNDER WITH THE LATE NIGHT TIMING OF THE
FRONT AND LIMITED INSTABILITY...ACCORDING TO THE MODEL CAPE FCST.

BEHIND THE FRONT ON FRIDAY...THE COLD ADVECTION AND NORTHWEST FLOW
SHOULD LEAD TO IMPROVING CONDITIONS. THE MODELS SHOW LOTS OF MID
LEVEL DRYING...BUT WILL HAVE TO WATCH THE SHORTWAVE ENERGY
ROTATING THROUGH THE BOTTOM OF THE TROUGH...AS IT COULD INDUCE
SOME WAVE DEVELOPMENT ALONG THE FRONT WHICH COULD SLOW THE FRONTS
PROGRESSION OFF THE COAST. BY FRIDAY NIGHT...THE TROUGH AXIS IS
OFF THE COAST AND CONDITIONS WILL CONTINUE TO IMPROVE. THE DRIER
AND COOL AIR WILL MOVE IN AS HIGH PRESSURE OVER THE SOUTHERN US
SLIDES EAST. BY SUNDAY...THE HIGH MOVES OVERHEAD AND WITH THE
RIDGING ALOFT TEMPERATURES WILL REBOUND WITH LOTS OF SUNSHINE
THROUGH THE DAY MONDAY.

FOR TEMPERATURES...HAVE MAINTAINED THE MILDER CONDITIONS THURSDAY
NIGHT WITH THE FRONT CROSSING AS THE COLD AIR LAGS AND CLOUDS
LINGER. BUT FOR HIGHS ON FRIDAY AND SATURDAY...SHOULD SEE COOLER
READINGS SO HAVE LOWERED TEMPS EACH DAY A FEW DEGREES. SAT NIGHT
SHOULD BE THE COOLEST OF THE PERIOD WITH GOOD RADIATIONAL COOLING
CONDITIONS. TEMPERATURES BEGIN TO REBOUND SUNDAY INTO MONDAY SO
HAVE STARTED TO PUSH TEMPERATURES A LITTLE WARMER WITH THE
TEMPERATURES ALOFT CLIMBING BACK ABOVE 10C AT 850 MB.

&&

.AVIATION /21Z MONDAY THROUGH SATURDAY/...
ANOTHER DRY AND WARM DAY ACROSS THE MID ATLANTIC STATES WITH VFR
CONDITIONS AT ALL OF THE TAF SITES. A LEESIDE TROUGH WAS FORMING
OVER THE VA PIEDMONT RESULTING IN SW WINDS OVER INLAND AREAS. WINDS
ALONG THE COAST WERE INFLUENCED BY LAND/SEA INTERACTIONS. WINDS NEAR
THE BAY-BRIDGE TUNNEL HAD BACKED TO NE/E BY 17Z. THIS COULD AFFECT
ORF BUT LEFT OUT OF THE TAF FOR NOW. WINDS OVER THE MD/DE EASTERN
SHORE HAVE ALSO BACKED TO S/SE.

DEW POINTS WILL REMAIN IN THE 50S OVERNIGHT. THIS WILL RESULT IN A
MEDIUM CONFIDENCE OF IFR FOG AT SBY AND LOW CONFIDENCE AT RIC AND
PHF. ONLY MVFR INCLUDED IN THE TAFS FOR NOW. TEMPERATURES SHOULD
REMAIN HIGH TO PRECLUDE FOG AT ORF AND ECG.

OTHER THAN PATCHY ERLY AM FOG (GNLY BETWEEN 07-12Z) VFR CONDS CAN BE
EXPECTED THROUGH THU. THERE WILL BE A LIKELIHOOD FOR PCPN THU NIGHT
AND EARLY FRI. MVFR/BRIEF IFR CAN BE EXPECTED AT THAT TIME. THE
WEATHER IMPROVES AGAIN FRI NIGHT AND SAT.

&&

.MARINE...
VERY QUIET WEATHER TO BEGIN THE PERIOD AS HIGH PRESSURE OFF THE SE
US COAST...IN A MORE TYPICAL SUMMER TIME PATTERN...MAINTAINS
CONTROL OF THE WEATHER THROUGH WEDNESDAY. WITH THE COLD WATER
STILL IN PLACE...MIXING SHOULD BE SOMEWHAT LIMITED OVER THE WATERS
SO DO NOT ANTICIPATE ANY SMALL CRAFT CONDITIONS THROUGH WED.

BY WED NIGHT INTO THURSDAY...THE NEXT STRONG FULL LATITUDE TROUGH
WILL APPROACH AND AT THE SURFACE A COLD FRONT WILL HELP TIGHTEN
THE GRADIENT. EXPECT SW FLOW TO INCREASE WITH SMALL CRAFT
CONDITIONS POSSIBLE LATE WED NIGHT INTO THURSDAY EVENING AHEAD OF
THE FRONT. WINDS 15 TO 25 KTS ARE EXPECTED IN ADVANCE OF THE
FRONT....BUT WITH THE SHORT DURATION OF WIND AND SW FLOW...SEAS
ARE ONLY EXPECTED TO BUILD TO 5 TO 6 FEET WITH THE STRONGER WINDS
THURS NIGHT INTO FRIDAY.

THE FRONT SHOULD CLEAR THE REGION BY FRIDAY MORNING WITH THE FLOW
TURNING WEST TO NORTHWEST...BUT WITH THE COLD WATER...THE NW FLOW
WILL PROBABLY NOT BE ENHANCED BY THE MIXING SO EXPECT TO SEE THE
WINDS GRADUALLY RELAX BY FRIDAY NIGHT AS HIGH PRESSURE NOSES IN.
BY SATURDAY...EXPECT HIGH PRESSURE AND BENIGN CONDITIONS TO BE IN
PLACE AND REMAIN THAT WAY THROUGH THE WEEKEND.

&&

.CLIMATE...
MUCH ABOVE NRML TEMPS WILL CONTINUE THROUGH WED/THU.

AT RICHMOND/RIC...THERE HAVE NOW BEEN 5 CONSECUTIVE DAYS WITH A
HIGH TEMPERATURES >=80 F...AND CURRENT FCST IS FOR THIS STREAK TO
EXTEND TO AT LEAST 7 DAYS (THROUGH WED)...AND PROBABLY EVEN 8 DAYS.
IF THE STREAK REACHES 8 DAYS...IT WOULD BREAK THE RECORD FOR
CONSECUTIVE 80+ DEGREES SO EARLY IN THE SEASON (PRIOR TO APR 15TH).
THE CURRENT RECORD OF 7 DAYS IN ROW (80F OR HIGHER) WAS SET BACK
IN MID MARCH 1990.

AS FOR 90 DEGREE STREAKS...NO RECORDS ARE EXPECTED. THE RECORD OF
4 CONSECUTIVE 90+ DEGREE DAYS PRIOR TO APR 15TH IN RICHMOND WAS
SET IN 1977.

DAILY RECORD HIGH TEMPERATURES TUESDAY AND WEDNESDAY:

    TUE 4/6  WED 4/7

RIC 92/1942  94/1929
ORF 92/1929  92/1929
SBY 88/1929  92/1929
