DISCUSSION
KEY MESSAGE 1
HIGH PRESSURE OVER THE AREA WILL GRADUALLY MOVE OFFSHORE LATE TODAY
AND REMAIN IN CONTROL THROUGH WEDNESDAY, KEEPING US DRY THROUGH THE
PERIOD. A PROGRESSIVE UPPER TROUGH WILL THEN SEND A COLD FRONT
TOWARDS THE AREA WEDNESDAY NIGHT INTO THURSDAY. A PRE-FRONTAL TROUGH
MAY PROVIDE ENOUGH MOISTURE CONVERGENCE AND LIFT FOR A SHOWER MAINLY
NORTH AND WEST OF THE CITY LATE WEDNESDAY NIGHT INTO THURSDAY
MORNING. GUIDANCE IS IN GOOD AGREEMENT WITH THE TRAILING COLD FRONT
MOVING THROUGH THE AREA LATE THURSDAY OR THURSDAY NIGHT. THE MODELED
PATTERN FAVORS LIMITED FORCING AND ONLY A BRIEF WINDOW FOR DEEPER
MOISTURE. THE LATEST NBM INDICATES LESS THAN LIKELY POPS (30 TO 50
PERCENT) THURSDAY AFTERNOON AND EVENING, WHICH LOOKS REASONABLE.
SPEED SHEAR WOULD BE SUFFICIENT FOR SEVERE WEATHER, BUT INSTABILITY
LOOKS LIMITED. SO WHILE THERE IS A CHANCE OF A THUNDERSTORM, SEVERE
WEATHER STILL LOOKS UNLIKELY AT THIS POINT. BOTH SPC AND WPC DO NOT
HAVE ANY OF THE FORECAST AREA WITHIN AT LEAST A MARGINAL RISK OF
SEVERE WX/FLASH FLOODING.
HIGH PRESSURE AND DRY CONDITIONS WILL RETURN FRIDAY INTO NEXT
WEEKEND WITH THE WARMEST DAYS OF THE WEEK BEING WEDNESDAY AND
THURSDAY.

AFTERNOON AND THEN SPREAD TO THE REST OF THE WATERS WEDNESDAY
NIGHT. THERE IS A CHANCE OF GALE FORCE GUSTS ON THE OCEAN LATE
WEDNESDAY NIGHT INTO THURSDAY MORNING EAST OF FIRE ISLAND INLET.
WITH THE GALE POTENTIAL BEING ONLY MARGINAL LATE IN THE 4TH
PERIOD INTO 5TH PERIOD, WILL HOLD OFF ON ISSUING A GALE WATCH,
BUT WILL CONTINUE TO MENTION THIS POTENTIAL IN THE HWO. OCEAN
SEAS BUILD TO 5-8 FT WEDNESDAY NIGHT INTO THURSDAY, WITH WAVES
ON LI SOUND BUILDING 3-4 FT. WINDS AND SEAS GRADUALLY DIMINISH
DURING THURSDAY, PROBABLY FALLING BELOW SCA LEVELS ON THE NON-
OCEAN WATERS BY THE END OF THE MORNING, AND DURING THURSDAY
NIGHT ON THE OCEAN. CONDITIONS BELOW SCA LEVELS WILL THEN
CONTINUE INTO NEXT SATURDAY.
RIP CURRENTS:
THERE IS A LOW RIP CURRENT RISK FOR THE OCEAN BEACHES TODAY WITH THE
LACK OF SIGNIFICANT WINDS OR SWELL.
S-SW WINDS INCREASE WEDNESDAY, ESPECIALLY IN THE AFTERNOON AND
EVENING. WIND SPEEDS 15-20 KT WILL HELP BUILD SEAS AND SWELL, BUT
MORE LIKELY LATE IN THE DAY AND EVENING. HAVE GONE WITH A MODERATE
RIP CURRENT RISK FOR NOW, BUT THE RISK COULD BECOME HIGH LATE IN THE
