MARINE WEATHER DISCUSSION FOR N ATLANTIC OCEAN
NWS OCEAN PREDICTION CENTER WASHINGTON DC
810 AM EDT TUE MAY 26 2015

.FORECAST DISCUSSION: MAJOR FEATURES/WINDS/SEAS/SIGNIFICANT
.WEATHER FOR THE NORTH ATLANTIC OCEAN W OF 50W FROM 30N TO 50N.

SUMMARY...THE QUIET WX PATTERN IS EXPECTED TO CONTINUE THRU THE
ENTIRE FCST PRD ACROSS THE OFSHR ZONES...WITH MAINLY LIGHT WINDS
AND SEAS 8 FT OR LESS. A HI PRES RIDGE WILL PERSIST OVER THE NT2
WTRS FOR TODAY THRU SAT NITE. AREAS OF LOW PRES WILL PASS N OF THE
NT1 AREA TODAY THRU WED NITE. A WEAK COLD FNT WILL MOVE SE AND
APRCH THE NEW ENG COAST THU...THEN DSIPT OVER THE GULF OF MAINE
THU NITE. A HI PRES RIDGE WILL BUILD SE OVER THE NT1 WTRS
FRI...THEN PASS SE ACROSS THE NT1 AREA FRI NITE INTO SAT. A STGR
COLD FNT WILL MOVE SE AND APRCH THE NEW ENG COAST LATE SAT...THEN
MOVE OFSHR INTO THE GULF OF MAINE SAT NITE.

MODELS...UKMET IS FASTEST MDL SOLN WITH THE COLD FNT FOR FRI NITE
THRU SAT NITE...WHILE NOGAPS IS THE SLOWEST MDL. ECMWF/GFS LOOK
LIKE BEST MEDIAN SOLNS FOR TIMING OF THE COLD FNT. GFS 30M SOLN IS
JUST A BIT OVERDONE WITH STRENGTH OF THE SW FLOW OVER THE NRN NT1
WTRS ON WED...THEN AGAIN LATE SAT AND SAT NITE. GFS 10M APRS TO BE
THE MOST REPRESENTATIVE MDL SOLN...AND WILL BE USED TO POPULATE
THE WIND GRIDS FOR THE ENTIRE FCST PRD. AM NOT PLANNING TO MAKE
ANY SIGNIF CHANGES TO THE CURRENT FCST TREND.

.SEAS...THE MULTIGRID WAVEWATCH III MDL AND ECMWF WAM BOTH INITIALIZED
WELL ACROSS THE CSTL/OFSHR WTRS. THESE MDLS ARE IN EXTREMELY GUD
AGREEMNT OVER THE OFSHR WTRS THRU THE ENTIRE FCST PRD...SO JUST
WENT WITH THE MWW3 MDL GUIDANCE FOR THE SEA HT GRIDS.

.EXTRATROPICAL STORM SURGE GUIDANCE...N/A.

.WARNINGS...PRELIMINARY.

.NT1 NEW ENGLAND WATERS...
     NONE.
