AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE UPTON NY
950 AM EDT FRI JUL 21 2006

.NEAR TERM (TODAY THROUGH TONIGHT)...
NO MAJOR CHANGES TO THE MORNING FORECAST AS TROPICAL STORM BERYL
CONTINUES MOVING AWAY FROM THE REGION ON A NE TRAJECTORY. IN ITS
WAKE...A DEEP S-SW FLOW WILL SET UP ACROSS THE EAST COAST. THIS WILL
PUSH SFC DEWPOINTS INTO THE LOWER 70S THROUGHOUT. ALTHOUGH MAX TEMPS
WILL BE IN THE LOWER TO MIDDLE 80S...IT WILL BE QUITE HUMID AND
UNCOMFORTABLE.

COLD FRONT OVER THE GREAT LAKES WILL BE PROPAGATING E THROUGHOUT THE
DAY. A SHORT WAVE OUT AHEAD OF THE COLD FRONT HAS SET OFF SHOWERS
AND THUNDERSTORMS ACROSS PORTIONS OF THE CWA THERFORE WILL CONTINUE
TO KEEP SLIGHT CHC TO CHC POPS THIS MORNING. WILL KEEP MORE LIKELY
POPS IN FOR THE AFTERNOON WHEN COLD FRONT NUDGES CLOSER AND IS ABLE
TO TRIGGER MORE WIDESPREAD SHOWERS/TSTMS ACROSS ENTIRE CWA STARTING
IN THE MID-AFTERNOON. FRONT BECOMES NEARLY STATIONARY BY THIS
EVENING AND WILL BE DRAPED OVER THE EASTERN SEABOARD. AS THIS
HAPPENS...A FAIRLY INTENSE WAVE OF LOW PRES WILL BE DEVELOPING ALONG
IT OVER E PA/W NJ. THIS LOW WILL THEN MOVE INTO THE AREA
TONIGHT...FOLLOWED BY YET ANOTHER WAVE DURING THE OVERNIGHT HOURS.

GIVEN ABUNDANT MOISTURE IN THE ATMOSPHERE...RAIN WILL BE HEAVY AT
TIMES...ESPECIALLY IN ANY TSTMS THAT DEVELOP. ALTHOUGH A FEW
ISOLATED SVR STORMS WILL BE POSSIBLE DURING THE LATE AFTERNOON
HOURS...NOT EXPECTING MUCH BEYOND THAT. GFS SOUNDING SHOWS WEAK
SHEAR ALONG WITH FAIRLY WEAK MID-LEVEL WINDS (GENERALLY 20-30 KTS).
THOUGH SOME GUSTY WINDS WILL BE POSSIBLE...WITH PWATS APPROACHING
2...MAIN CONCERN WILL BE POTENTIAL FOR FLOODING. EACH WAVE OF LOW
PRES WILL HAVE THE POTENTIAL FOR HEAVY RAIN. HAVE STAYED CLOSE TO
GFS GIVEN SUPERIOR PERFORMANCE OVER WRF OF LATE. BOTH MODELS SHOWING
DIFFERING SOLUTIONS IN TERMS OF WHERE COLD FRONT WILL BECOME NEARLY
STATIONARY. FOR THIS REASON...HAVE DECIDED TO HOLD OFF ON FLASH
FLOOD WATCH...BUT WILL ISSUE SPS INDICATING FLOODING POTENTIAL AND
WILL ALSO MENTION IN THE HWO.

MIN TEMPS TONIGHT WILL BE 70S WITH NEARLY IDENTICAL DEWPOINTS.
&&

.SHORT TERM (SATURDAY THROUGH SUNDAY)...
SEVERAL WAVES OF LOW PRES WILL DEVELOP ALONG THE NEARLY STATIONARY
COLD FRONT DRAPED ACROSS THE AREA. HOWEVER...PLACEMENT OF FRONT WILL
HAVE GREAT IMPACT ON THE TRACK OF EACH WAVE. ALTHOUGH THE GFS WAS
FAVORED DURING THIS TIME FRAME...HAVE SCALED BACK ON POPS/QPF IN
ATTEMPT TO INDICATE A BLEND WITH WRF. PWATS WILL RANGE FROM
2-2.5...AND HEAVY RAIN WILL BE POSSIBLE THROUGHOUT THE WEEKEND.
CURRENT THINKING HAS HEAVIEST RAIN OCCURRING FROM ABOUT MIDDAY SAT
THROUGH LATE SAT NIGHT AS STRONGEST OF THE WAVES MOVES ACROSS THE
AREA. CONFIDENCE LOW ON SUN...AS FRONT BEGINS TO SAG S. THIS COULD
BRING POPS DOWN...MAINLY N AND W OF NYC...WHILE ANOTHER WAVE SLIDES
THROUGH LONG ISLAND AND E CT. HAVE KEPT CHC POPS IN THE FCST THROUGH
SUN AFTERNOON. MAX TEMPS SAT WILL BE IN THE LOWER 80S...THEN COOLS
OFF TO THE UPPER 70S ON SUN. HUMIDITY LEVELS WILL BEGIN TO FALL ON
SUN AS DRYER AIR FILTERS INTO THE AREA BEHIND THE FRONT AS HIGH PRES
SLOWLY NUDGES E.
&&

.LONG TERM (SUNDAY NIGHT THROUGH THURSDAY)...
DRYER AIR WILL MOVE INTO THE AREA SUN NIGHT...AND SKIES WILL BEGIN
TO CLEAR OUT. HAVE GONE DRY AS HIGH PRES PASSES THROUGH THE EAST
COAST...MOVING OFFSHORE LATE MON. ANOTHER WAVE OF LOW PRES MAY SLIDE
N ON TUE...BRINGING ANOTHER CHC FOR SHOWERS/TSTMS. THE THREAT OF
SHOWERS AND TSTMS WILL CONTINUE ON WED AFTERNOON AND THU AS A COLD
FRONT APPROACHES THE REGION. TEMPERATURES THROUGH THE LONG TERM WILL
BE NEAR NORMAL AS DAYTIME HIGHS CLIMB INTO THE 80S AND OVERNIGHT
LOWS DROP INTO THE UPPER 60S AND LOWER 70S.
&&

.AVIATION...
MVFR CONDITIONS ASSOCIATED WITH A LINE OF T-STORM THAT MOVED ACROSS
THE AREA THIS MORNING ACROSS ALL TERMINALS...LIFTING TO VFR
SHORTLY. THEN MVFR CIGS/VSBY IN OR NEAR TSTMS THIS AFTN-EVE WITH
GUSTY W WIND 25-40KT POSSIBLE...AS A COLD FRONT MOVES IN FROM THE
NORTHWEST.
&&

.MARINE...
WINDS AND SEAS HAVE SUBSIDED TO BELOW SCA ON THE OCEAN WATERS THIS
MORNING AS T.S. BERYL MOVES AWAY FROM THE REGION. AS A RESULT...WILL
GO AHEAD AND DROP THE SCA FOR THE LATE MORNING AND EARLY AFTERNOON
HOURS. AT THE SAME TIME...AN APPROACHING COLD FRONT THIS EVENING
WILL BECOME NEARLY STATIONARY IN THE VICINITY OF THE WATERS THROUGH
THE UPCOMING WEEKEND. A WAVE OF LOW PRESSURE ALONG THE FRONT ON SAT
WILL TRACK NORTHEAST ACROSS THE MID ATLANTIC STATES AND INTO THE
NORTHEAST SAT NIGHT. THIS LOW WILL DEEPEN SOMEWHAT IN RESPONSE TO AN
AMPLIFYING UPPER TROUGH OVER THE GREAT LAKES AND OHIO VALLEY STATES.
AT THE SAME TIME...HIGH PRESSURE OVER THE WESTERN ATLANTIC WILL
ALLOW FOR A TIGHTENING PRESSURE GRADIENT ACROSS THE WATERS WITH
SMALL CRAFT CONDITIONS DEVELOPING SAT MORNING EAST OF FIRE ISLAND
INLET. THESE CONDITIONS ARE LIKELY TO PERSIST INTO SUN AFT. HIGH
PRESSURE WILL FOLLOW SUN EVENING INTO MON WITH DIMINISHING WINDS AND
SEAS.
&&

.HYDROLOGY...
COLD FRONT MOVING INTO THE AREA WILL BECOME NEARLY STATIONARY
TONIGHT...THEN SEVERAL WAVES OF LOW PRES WILL AFFECT THE AREA
THROUGH THE WEEKEND. BETWEEN 1.5 AND 3.0 INCHES OF RAIN WILL BE
POSSIBLE DURING THIS TIME. LOCALIZED FLOODING WILL BE OF CONCERN.
