.SYNOPSIS...
HIGH PRESSURE WILL STRENGTHEN OVER NORTHERN NEW ENGLAND AND THE
CANADIAN MARITIMES TONIGHT...WHILE LOW PRESSURE WILL TRACK
FROM THE GULF COAST NORTHEAST TO JUST OFF THE SOUTHEAST COAST.
THE LOW WILL MOVE UP THE EASTERN SEABOARD MONDAY THROUGH TUESDAY.
A WEAK COLD FRONT WILL APPROACH FROM THE WEST LATE WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
CLDS WILL INCRS AND THICKEN FM SW TO NE TNGT IN ADVANCE OF LO PRES
MOVNG FM THE FL PANHANDLE NE TO JUST OFF THE SE CST. IT WILL TAKE
SOME TIME TO SATURATE MID/LO LVLS OF THE AIRMASS (SW-NE) OVR THE
REGION...WITH MEASURABLE RAINFALL NOT MOVNG INTO THE SRN/SW CNTIES
UNTIL LATER THIS EVENG. RAIN WILL THEN SPREAD ACRS THE REGION FM
SW TO NE OVRNGT INTO MON MORNG. MIN TEMPS IN THE MID 40S TO LWR
50S.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
LO PRES MOVES UP THE ERN SEABOARD MON THRU TUE. MOIST NE ONSHR FLO
AHEAD OF THE LO WILL HELP TO PROVIDE A DECENT RAINFALL ACRS THE
AREA DURING MON INTO ERLY MON EVENG (ESPLY LWR MD). QPF AMTS SHUD
BE BETWEEN .25 INCH TO .50 INCH MOST AREAS...WITH HIER TOTALS
POSSIBLE OVR THE SE. MAX TEMPS ON MON RANGING THRU THE 50S TO LWR
60S.
LO PRES WILL MOVE FARTHER AWAY UP THE CST LATER MON NGT THRU TUE
WITH WEAK SFC HI PRES OVR THE REGON TUE AND TUE NGT. HOWEVER...STILL
EXPECT A MSTLY CLDY OR CLDY SKY TO DOMINATE OUR WX DURING THIS
PERIOD...AS FCST AREA REMAINS IN AN IN-SITU WEDGE SCENARIO WITH LO
LVLS MOIST ARND 850-900MB AND BELOW. VRY LGT RAIN OR PATCHY DRIZZLE
STILL POSSIBLE ESPLY TUE MORNG...AND PATCHY DRIZZLE POSSIBLE AGAIN
ALL AREAS TUE NGT. LOWS MON NGT IN THE MID 40S TO LWR 50S. HIGHS
ON TUE IN THE MID TO UPR 50S.
GENERALLY MSTLY CLDY STILL ON WED WITH A SLGT CHC OF SHRAS IN THE
AFTN/EVENG...AS A WEAK COLD FRNT APPROACHES FM THE W. MAX TEMPS IN
THE UPR 50S TO LWR 60S.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
BY WED NGT/THANKSGIVING DAY...GFS/ECMWF NOW BOTH SHOW A FAIRLY WEAK
SFC PRESSURE PATTERN ACRS THE MID ATLC...WITH A DEVELOPING SFC LOW
MOVING UP THE SE COAST. THE LOW STRENGTHENS AS IT TRACKS NNE AND OFF
THE VA CAPES/MID ATLC COAST THU NGT/FRI. CARRIED 20-40% CHANCES FOR
SHWRS THANKSGIVING DAY AND NIGHT (HIGHEST POPS ALONG THE COAST).
AFTER THAT...GFS/ECMWF HAVE TRENDED FARTHER SOUTH WITH THE UPR
LOW...NOW CLOSING IT OFF IN THE VICINITY OF THE REGION FRI/FRI NGT.
STILL SOME DISCREPANCIES...WITH A CONSENSUS OF THE GFS/ECMWF STILL
KEEPING THE MAIN SHORTWAVE ENERGY OVER VA (RATHER THAN THE
CAROLINAS). GIVEN THIS TRACK...HAVE TRENDED THE FCST A BIT CLOUDIER
AND ADDED 20-30% CHANCES FOR PRECIP FRI AFTN/EVENING FOR CNTRL AND
NRN ZONES...BUT WILL KEEP THE SOUTH DRY. ADDED A BIT MORE IN THE WAY
OF CLOUD CVR SAT (PTLY SUNNY) BUT OVERALL A COOL DRY PATTERN SHOULD
PREVAIL W/ WESTERLY LOW LVL FLOW. HIGHS FRI/SAT...ARND 50 FAR NORTH
TO MID 50S SOUTH. DRY W/ A SLIGHT WARMING TREND SUNDAY AS RIDGING
SLOWLY BUILDS BACK INTO THE E COAST FROM THE SW...HIGHS MID/UPR 50S.
&&
.AVIATION /00Z MONDAY THROUGH FRIDAY/...
LATEST RADAR IMAGERY SHOWS A LINE OF SCTD SHWRS CURRENTLY MVG NE
ACRS SOUTH CENTRAL VA. ADDED TEMPO GROUP AT RIC FOR THIS REASON.
OTHERWISE...THE BULK OF RAIN HAS MVD INTO THE CAROLINAS AHEAD OF
AN UPR LOW CURRENTLY IN TN. THIS LOW WL REACH THE MID ATLANTIC
STATES DURING THE EARLY MORNING HOURS WITH RAIN MVG INTO ALL TAF
SITES EXCEPT SBY BY 09Z. PREDOMINANTLY MVFR CONDITIONS WL
CONTINUE THROUGH MON WITH PERIODS OF IFR POSSIBLE EARLY MON MRNG
ASSOCIATED WITH PATCHY FOG AND AREAS OF HEAVIER PCPN.
THE MAIN AREA OF RAIN MOVES OUT MON EVNG BUT MOIST NRLY FLOW WL
LIKELY KEEP IFR CIGS IN THE AREA INTO TUE. CONDS WL IMPROVE BY
WED AS HI PRES SETTLES OVER THE AREA.
THE NEXT CHC FOR PCPN AND LWR CIGS LOOKS TO BE THU AS A FNTL
SYSTEM MVS ACRS THE AREA. DOWNSLOPING NW FLOW SHOULD BRING VFR
CONDITIONS BACK ON FRI.
&&
.MARINE...
SEAS OVER THE CSTL WATERS ARE RISING FAST THIS EVENING AND HAVE
BUMPED SEAS UP A FEW FEET...TO 5-7 FT S AND 6-8 FT NORTH. SCA HEADLINES
ARE NOW IN EFFECT FOR ALL ZONES. MAIN STORY OVER THE NEXT 24-36
HRS WILL BE THE INCREASING PRESSURE GRADIENT BETWEEN A DEVELOPING
LOW PRESSURE SYSTEM OFF THE SE US COAST...AND A 1035+ MB HIGH OVER
NEW ENGLAND. MODELS HAVE TRENDED FARTHER EAST/OFF THE CANADIAN
MARITIMES W/ THE POSITION OF THE SFC HIGH MONDAY AND MONDAY
NIGHT...WHICH WOULD LEAD TO A SOMEWHAT WEAKER PRESSURE GRADIENT
THAN THEY HAD SHOWN YSDY. WILL KEEP SCA HEADLINES FOR MON (NO
GALES)...BUT IT MAY BE CLOSE AND ANTICIPATE A PERIOD OF AT LEAST 25
KT SUSTAINED WINDS ON THE COAST ALONG WITH GUSTS TO AROUND 30 KT.
WILL ALSO CONTINUE TO FCST SEAS ABOUT 1-2 FT HIGHER THAN WAVEWATCH
(UP TO 8-9 FT OFFSHORE NRN CSTL WATERS). WINDS TURN TO THE NNW AND
SLOWLY DIMINISH LATER MON NGT AS THE LOW PUSHES OFF THE MID ATLC
COAST...BUT SCA HEADLINES STAY UP THROUGH THE 4TH PERIOD/TUE AFTN
FOR THE CSTL WATERS DUE TO RESIDUAL SWELL/SEAS 5 FT+. ANOTHER SFC
LOW WILL DEVELOP AND STRENGTHEN OFF THE COAST FRI INTO THE
WEEKEND...WITH A STRG WNW FLOW EXPECTED OVER THE WATERS.
