AREA FORECAST DISCUSSION...UPDATED MARINE
NATIONAL WEATHER SERVICE UPTON NY
509 AM EDT THU SEP 15 2005

...MUCH NEEDED RAINS ON THE WAY...

.NEAR TERM (TODAY AND TONIGHT)...
FORECAST AREA ALREADY SEEING THE IMPACTS OF HIGH PRECIPITABLE WATER
(AROUND 2 INCHES) IN A MARGINALLY UNSTABLE AIRMASS. DEEP-LAYERED
TROPICAL MOISTURE CONTINUES TO ADVECT NORTHWARD AHEAD OF HURRICANE
OPHELIA AND AROUND THE PERIPHERY OF THE WESTERN ATLANTIC RIDGE.
SHOWERS TRACKING NEWD ACROSS CT HAVE RESULTED IN LOCALIZED HEAVY
RAIN WITH OXC REPORTING 1.34 INCHES IN AN HOUR. CURRENT CONVECTION
ACROSS SOUTHERN CT REMAINS SCATTERED IN NATURE.

SEVERAL MODELS CONTINUE TO TREND TOWARD A MORE AMPLIFIED UPPER
TROUGH PUSHING INTO THE OHIO VALLEY THIS WEEKEND. THIS IN TURN IS
SLOWING THE UPPER PATTERN AND KEEPING RAIN THREATS IN THROUGH THE
UPCOMING WEEKEND. ADDITIONALLY...SHOULD THIS TREND HOLD TRUE...A
WESTWARD ADJUSTMENT TO OPHELIA IS POSSIBLE. PLEASE REFER TO THE
LATEST NATIONAL HURRICANE CENTER ADVISORIES FOR FURTHER INFORMATION
ON OPHELIA.

COLD FRONT OVER THE OHIO VALLEY PRESSES EASTWARD TODAY AND INTO THE
FORECAST AREA LATE THIS AFTERNOON/EARLY THIS EVENING. THE FRONTAL
FORCING IN CONJUNCTION WITH A TROPICAL AIRMASS IS LIKELY TO RESULT
IN HEAVY SHOWERS. IN ADDITION...INVERTED TROF ALONG COASTAL PLAIN
SHOULD PROVIDE ENOUGH FOCUS FOR SHOWERS PRIOR TO THE ARRIVAL OF THE
COLD FRONT.
&&

.SHORT TERM (FRIDAY THROUGH SATURDAY)...
AFOREMENTIONED COLD FRONT STALLS ACROSS SOUTHERN NEW ENGLAND ON FRI
AS HEIGHTS BUILD ONCE AGAIN ACROSS THE REGION. THIS IS IN RESPONSE
TO THE UPPER TROUGH MOVING INTO THE OHIO VALLEY. SHOWERS WILL STILL
BE A GOOD BET THOUGH AS THE TROPICAL MOISTURE LIFTS UP AND OVER THE
FRONTAL BOUNDARY. LOCALIZED HEAVY RAINFALL WILL LIKELY PRODUCE URBAN
AND POOR DRAINAGE FLOODING. ISOLATED THUNDERSTORMS WILL ALSO BE
POSSIBLE. LONG NARROW CAPES ON BUFKIT SOUNDINGS TYPICAL OF A
TROPICAL AIRMASS WITH HEAVY RAIN PRODUCING SHOWERS. RAINFALL COULD
BE ENHANCED ACROSS THE HIGHER TERRAIN OF THE LOWER HUDSON VALLEY AND
NORTHERN NJ IN A STRENGTHENING EASTERLY FLOW.

UPPER RIDGE BREAKS DOWN LATE FRI AS HURRICANE OPHELIA TRANSITIONS
INTO AN EXTRATROPICAL SYSTEM...TRACKING SOUTH AND EAST OF LONG
ISLAND. EASTERN SECTIONS OF THE ISLAND WILL LIKELY SEE BREEZY
CONDITIONS OUT OF THE ENE WITH THE POTENTIAL FOR SQUALLS IN THE
OUTER RAINBANDS.

FRONTAL BOUNDARY ASSOCIATED WITH THE UPPER TROUGH TO THE WEST WILL
MOVE THROUGH ON SAT WITH MORE SHOWERS ON TAP.

&&

.LONG TERM (SATURDAY NIGHT THROUGH WEDNESDAY)...
UPPER TROUGH MOVES ACROSS FORECAST AREA SAT NIGHT WITH CONDITIONS
IMPROVING DURING THE DAY SUN. A RIDGE BEGINS TO BUILD INTO THE LOCAL
AREA FROM THE WEST. THUS...IMPROVING CONDITIONS EXPECTED THROUGH THE
FIRST PART OF THE EXTENDED. THIS RIDGE DOMINATES THE LOCAL AREA INTO
EARLY NEXT WEEK BEFORE IT SHIFTS OFFSHORE MONDAY NIGHT. MOISTURE
LEVELS INCREASE FROM MONDAY NIGHT ONWARD AS SOUTHERLY FLOW SETS UP.
WARM FRONT APPROACHING TUESDAY...DRIFTS UP THROUGH THE TRI-STATE
REGION BY LATE IN THE DAY PRESENTING A MINIMAL CHANCE OF SHOWERS.
THE LOCAL AREA REMAINS IN THE WARM SECTOR TUESDAY NIGHT AND
WEDNESDAY WITH A CONTINUING CHANCE OF SHOWERS.

DAYTIMES HIGHS 70 TO 75 FOR THE WEEKEND...CLIMB A BIT EACH DAY
THEREAFTER WITH THE WARMEST READINGS OF 80 TO 85 ON WEDNESDAY.
OVERNIGHT LOWS IN THE 50S TO AROUND 60S THROUGH EARLY NEXT
WEEK...THEN ALSO A SLOW RISE EACH NIGHT THEREAFTER.
&&

.AVIATION...
LIGHT ONSHORE FLOW WILL CONTINUE TO IMPORT MOISTURE LADEN AIR INTO
THE REGION TODAY. SHOWERS WILL BE LIKELY TODAY ACROSS THE AREA AS AN
APPROACHING SHORTWAVE/WEAK FRONT INTERACTS WITH THIS AIRMASS.

PREDOMINANTLY HIGH END MVFR/VFR VSBYS THROUGH THE FORECAST
PERIOD...HOWEVER...KJFK AND KHPN COULD BE LIFR AT TIMES THRU
11-12Z...AND KISP POSSIBLY IFR. CIGS ARE MORE OF A CHALLENGE EARLY
THIS MORNING AS THEY HAVE BEEN VARYING ACROSS THE AREA IN THIS
TROPICAL AIRMASS. MOST SPOTS GENERALLY MVFR OR LOWER THROUGH ROUGHLY
14Z...THEN MAINLY MVFR THEREAFTER. THERE SHOULD BE ENOUGH MOISTURE
AROUND TO PREVENT DECKS FROM SCATTERING OUT FOR ANY SIGNIFICANT
LENGTH OF TIME DESPITE DAYTIME HEATING.

LOOKS LIKE VSBYS AND CEILINGS WILL COME DOWN A LITTLE THIS EVENING
WITH THE LOSS OF DAYTIME HEATING AND A MOIST AIRMASS STILL IN PLACE.
BACKING WINDS WILL REMAIN ON THE LIGHT SIDE.
&&

.MARINE...
CWF DELAYED FOR 5 AM TPC OPHELIA ADVISORY...WHOSE TRACK AND 34-KT
WIND RADII HAVE SHIFTED FAR ENOUGH LEFT (WITH CLOSEST APPROACH 100
NM SE MONTAUK POINT SOME TIME LATE FRI NIGHT OR EARLY SAT MORNING)
TO POSSIBLY GRAZE FAR EASTERN WATERS WITH SUSTAINED TROPICAL STORM
FORCE WINDS.

WINDS AND SEAS ARE CURRENTLY BELOW SCA CRITERIA ON ALL WATERS...BUT
THIS WILL CHANGE FAIRLY SOON AS OPHELIA HEADS IN A GENERAL N-NE
DIRECTION OVER THE NEXT COUPLE OF DAYS. SEAS ON THE OCEAN WILL
LIKELY INCREASE TO 4-6 FT TONIGHT...THEN TO 6-10 FT OR HIGHER
FRI NIGHT.

RIGHT NOW WILL JUST HEADLINE SCA FOR THE OCEAN...BUT BASED ON TPC
TRACK AND INTENSITY FORECAST...A TROPICAL STORM WATCH COULD BE
ISSUED LATER TODAY OR TONIGHT FOR A PORTION OF THE WATERS...MOST
LIKELY ON THE OCEAN FROM MORICHES-MONTAUK.

TIDES ARE ASTRONOMICALLY HIGH. THE THREAT FOR MINOR COASTAL FLOODING
WILL INCREASE...AND BECOME MOST LIKELY FRI AND FRI NIGHT...POSSIBLY
INTO SAT.
&&

.HYDROLOGY...
TROPICAL MOISTURE WILL CONTINUE TO STREAM NORTHWARD AND INTERACT
WITH AN APPROACHING COLD FRONT OVER THE GREAT LAKES. THIS FRONT WILL
PUSH INTO THE REGION THURSDAY NIGHT. THEREFORE...THERE IS THE
POTENTIAL FOR SOME MUCH NEEDED RAINFALL. AT THE PRESENT TIME...WE
ARE LOOKING AT A GENERAL ADDITIONAL RAINFALL TOTAL OF BETWEEN 1 AND
1 1/2 INCHES TODAY INTO SATURDAY. LOCALIZED HIGHER AMOUNTS POSSIBLE
DUE TO THE TROPICAL NATURE OF THE AIRMASS.

THE DRY SUMMER SEASON SHOULD HAVE THE LOCAL BASINS RATHER RECEPTIVE
FOR ANY RAINFALL. BUT LOCALLY 1 TO 3 INCHES OF RAIN HAS FALLEN OVER
NORTHEASTERN NEW JERSEY AND AROUND AN INCH OVER PORTIONS OF THE
LOWER HUDSON VALLEY AND SOUTHWEST CT WEDNESDAY EVENING. ADDITIONAL
RAINFALL IN THESE AREAS MAY PRESENT A GREATER LIKELIHOOD OF SOME
URBAN AND SMALL STREAM FLOODING ISSUES.
&&

.FIRE WEATHER...
THE THREAT FOR WILDFIRES WILL BE SEVERELY DIMINISHED OVER THE NEXT
SEVERAL DAYS DUE TO A PROLONGED PERIOD OF WETTING RAINS.
&&

.OKX WATCHES/WARNINGS/ADVISORIES...
CT...NONE.
NY...NONE.
NJ...NONE.
MARINE...SCA FOR HAZARDOUS SEAS TONIGHT-SUN MORNING...ANZ355-353-350.
