AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE UPTON NY
633 PM EDT MON AUG 30 2004

.SHORT TERM (TONIGHT)...
WITH WITH BAND OF SHOWERS AND THUNDERSTORMS HAVING MOVED THROUGH
MUCH OF THE AREA AND WITH THE LOSS OF DAYTIME HEATING HAVE LOWERED
THE CHANCES...BUT KEPT LIKELY POPS ACROSS THE EXTREME INTERIOR
NORTHWEST PORTIONS. HEAVY RAINS POSSIBLE WITH THE SLOW MOVING STORMS
COULD PRODUCING SOME LOCALIZED FLOODING.
&&

.PREVIOUS DISSCUSSION (410 PM EDT MON)...

SHORT TERM (TUE AND NIGHT)...

THE REMNANTS OF GASTON CONTINUE TO SPIN SLOWLY NORTHEAST NEAR THE
EASTERN HALF OF THE NORTH CAROLINA/VIRGINIA BORDER. THIS WILL
CONTINUE TO TRACK NORTHEAST...AND IS EXPECTED TO TRACK JUST SOUTH
AND EAST OF LONG ISLAND TUESDAY MORNING. MEANWHILE...A NEARLY
STATIONARY FRONTAL BOUNDARY EXTENDS FROM SOUTHERN ONTARIO...THROUGH
WESTERN NEW YORK AND PENNSYLVANIA. REGIONAL RADAR MOSAICS CLEARLY
INDICATE LINES OF CONVECTION WITHIN ABOUT A 100 MILE BAND JUST TO
THE EAST OF THE ACTUAL FRONT. THIS WILL MOVE VERY SLOWLY THROUGH THE
REMAINDER OF TODAY...AND WONT START TO PROGRESS EASTWARD UNTIL IT
IS PROMPTED BY THE COMBINATION OF A SHORTWAVE KICKER IN THE
MIDWEST...AND THE EVENTUAL LIFTING OUT OF THE REMNANTS OF GASTON.
DUE TO THE SLOW EASTWARD SHIFT OF THIS BAND OF ENHANCED
PRECIPITATION UNTIL THE ENTIRE PATTERN BECOMES MORE
PROGRESSIVE...WILL FORECAST THIS BAND TO REMAIN NORTH AND WEST OF
OUR LOWER HUDSON VALLEY ZONES. WE WILL RECEIVE VERY HEAVY RAIN WHEN
THIS BOUNDARY DOES TRAVERSE THE TRI-STATE REGION...HOWEVER FLOODING
CONCERNS ARE DECREASED BY THE FACT THAT THE BAND WILL MOVE AS IT
CROSSES THE LOCAL AREA.

THE THIRD CONCERN IS TROPICAL STORM HERMINE...WHICH IS EXPECTED TO
TRACK NEAR NANTUCKET LATE TONIGHT. ALL OF THE WINDS ASSOCIATED WITH
THIS STORM ARE LOCATED TO THE EAST OF THE CENTER SO THIS SHOULD NOT
DIRECTLY IMPACT OUR AREA. TWO INDIRECT IMPACTS WILL BE THE
GENERATION OF ROUGH SEAS AND SWELLS WHICH WILL AFFECT THE WATERS
TONIGHT AND TUE...AND THE ADVECTION OF MORE TROPICAL MOISTURE INTO
THE REGION.

EXPECT THAT THERE WILL BE TWO BANDS OF HIGHER QPF OVER THE 24 HOURS.
ONE...ASSOCIATED WITH THE FRONTAL BOUNDARY...SHOULD STAY JUST TO OUR
NORTH AND WEST...WHILE THE OTHER...ASSOCIATED WITH THE REMNANTS OF
GASTON PASSES JUST SOUTH AND EAST...OR CLIPS LONG ISLAND. IN
BETWEEN...FOR MOST...IF NOT ALL... OF THE CWA...WILL BE A LULL
BETWEEN THE TWO SYSTEMS. I STILL THINK THAT WE WILL SEE THE FRONTAL
BOUNDARY AND ITS BANDING TRAVERSE THE REGION LATE TONIGHT INTO EARLY
TUESDAY. HOWEVER...THE FORWARD MOTION OF THE BANDS SHOULD BE
SUFFICIENT ENOUGH TO KEEP QPF AMOUNTS TO AROUND 1 INCH IN MANY
LOCATIONS.

THE COLD FRONT SHOULD MOVE ACROSS THE REGION ON TUESDAY...CLEARING
EASTERN LOCALES BY MID-LATE AFTERNOON. THEN...HIGH PRESSURE WILL
START TO BUILD IN FROM THE NORTHWEST.

LONG TERM (WED THRU MON)...HIGH PRESSURE BUILDS IN AND WE WILL
REMAIN UNDER THE INFLUENCE OF A LARGE MID AND UPPER LEVEL RIDGE.
THIS WILL KEEP US DRY THROUGH THIS PERIOD...HOWEVER...WE WILL HAVE
TO MONITOR THE PROGRESS OF FRANCES BY DAY 7.

HYDROLOGY...THE BAND OF HEAVIEST QPF WITH THE REMNANTS OF GASTON IS
FORECAST TO TRACK EITHER ACROSS EASTERN PORTIONS OF THE CWA...WHICH
WILL BE ABLE TO TOLERATE A FAIR AMOUNT OF RAIN...OR JUST SOUTH AND
EAST OF LONG ISLAND. BASIN AVERAGE RAINFALL OF 1 TO 2 INCHES IS
EXPECTED TONIGHT INTO EARLY TUESDAY. THIS IS WELL BELOW FLASH FLOOD
GUIDANCE...HOWEVER...THERE WILL BE LOCALLY HEAVIER AMOUNTS THAT
WELL HAVE TO KEEP AN EYE OUT FOR...MAINLY FOR URBAN AND POOR
DRAINAGE AREA FLOODING. MEANWHILE...BANDS OF HEAVY RAIN ASSOCIATED
WITH AN APPROACHING COLD FRONT WILL CROSS THE REGION LATE TONIGHT
INTO TUESDAY MORNING. HOWEVER...PROGRESSION OF THIS CONVECTION
SHOULD BE ENOUGH TO AVOID FLOODING PROBLEMS. ONE CAVEAT...BANDS OF
2-4 INCHES OF FORECAST QPF WILL BE LOCATED BOTH TO OUT NORTHWEST AND
SOUTHEAST. ANY SHIFT IN THE TRACK OF EITHER THE REMNANTS OF GASTON
OR THE FRONTAL CONVERGENCE ZONE WILL BRING THE HEAVIER QPF CLOSER OR
POSSIBLY OVER THE REGION.

AVIATION...CIGS HAVE LIFTED THE LAST SEVERAL HOURS WITH ONLY SOME
ISOLATED AREAS OF MVFR OR LOWER STILL HANGING ON. HOWEVER...DO NOT
EXPECT TO SEE ANY FURTHER IMPROVEMENT WITH REGARD TO THIS...INDEED
MVFR OR LOWER CIGS SHOULD BECOME INCREASINGLY WIDESPREAD...
ESPECIALLY FROM THIS EVENING ON. IFR OR LOWER EXPECTED AGAIN TOWARD
DAYBREAK AND THEN GRADUAL IMPROVEMENT FROM MID TO LATE MORNING ON.
VSBY AT ALL TERMINALS ARE CURRENTLY UNRESTRICTED AND EXPECTED TO
REMAIN SO OUTSIDE OF ANY CONVECTION THROUGH THE REMAINDER OF TODAY.
HOWEVER ANY SHOWERS/THUNDERSTORMS WILL LOWER VSBY. WITH REGARD TO
PRECIPITATION...BELIEVE ACTIVITY WILL BECOME INCREASINGLY
WIDESPREAD. THREAT SHOULD REMAIN HIGH THROUGH THE NIGHT THEN TAPER
OFF FROM WEST TO EAST FROM AROUND MIDDAY ON TUESDAY. HOWEVER UNTIL
THAT HAPPENS...WITH PRECIPITABLE WATER LEVELS RUNNING QUITE
HIGH...TORRENTIAL DOWNPOURS A THREAT. WINDS BACK AROUND DURING THE
TAF PERIOD WITH NOTHING OF CONSEQUENCE EXPECTED.

MARINE...HAVE PUT UP SCA FOR ROUGH SEAS ON THE OCEAN WITH SEAS
COMING UP LATE. MAIN FORECAST CONCERN IN THE NEXT 18 HOURS ARE THE
REMNANTS OF GASTON WHICH WILL TRACK JUST SOUTH AND EAST OF THE
AREA...SKIRTING THE COASTAL WATERS LATE TONIGHT AND EARLY TOMORROW
WITH HEAVY RAIN. T.S. HERMINE...WHICH CAN BE NICELY SEEN ON VISIBLE
SATELLITE JUST WEST OF BUOY 44004...WILL RACE UP TOWARD CAPE COD BY
AROUND 06Z TONIGHT. CIRCULATION WITH HERMINE IS VERY SMALL WITH THE
STRONGEST WINDS TO THE EAST OF THE CENTER...SO ONLY EXPECTING A
QUICK SHOT OF SUB SCA CRITERIA WINDS FROM AROUND 00Z TO 04Z. SEAS
WILL COME UP TO SCA LATE TONIGHT...PRIMARILY ON SE SWELL AHEAD OF
THESE TROPICAL SYSTEMS. FURTHERMORE...HIGH ASTRONOMICAL TIDES ALONG
THE OCEAN WILL CONTINUE TO BE CLOSELY WATCHED WITH TIDAL DEPARTURES
AROUND 1/2 FT FORECAST AT TIME OF HIGH TIDE TUESDAY MORNING.
EXPECTED HIGH TIDES STILL LOOK TO BE GENERALLY 1/2 FT TO 1 FT BELOW
MINIMAL FLOODING LEVELS THOUGH...SO WILL NOT PUT IN FORECAST. COLD
FRONT WORKS THROUGH THE REGION BY TOMORROW AFTERNOON BEHIND REMNANTS
OF GASTON...WITH WINDS BECOMING NW. SEAS AND WINDS GRADUALLY SUBSIDE
TUESDAY NIGHT BELOW SCA AS HIGH PRESSURE BUILDS OVER THE WATERS.
CONTINUED RATHER TRANQUIL THROUGH THE REMAINDER OF THE FORECAST
PERIOD WITH HIGH PRESSURE REMAINING.

INCREASINGLY DEEP TROPICAL MOISTURE WILL MOVE UP ALONG THIS BOUNDARY

BASIN AVERAGE RAINFALL OF ONE TO TWO INCHES ACROSS THE LOCAL
AREA IS FORECAST...WITH THE HIGHEST AMOUNTS EXPECTED ACROSS EASTERN
PORTIONS. HOWEVER...THERE WILL BE LOCALLY HIGHER AMOUNTS THAT WE/LL

HIGH PRESSURE IS THEN FORECAST TO BUILD INTO THE REGION FROM THE
