MARINE WEATHER DISCUSSION FOR N ATLANTIC OCEAN
NWS OCEAN PREDICTION CENTER WASHINGTON DC
813 AM EDT MON MAY 25 2015

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

SUMMARY...A QUIET WX PATTERN IS FCST TO PREVAIL OVER THE OFSHR
WTRS THRU THE FCST PRD. LATEST AVAIL ASCAT PASSES SHOW LIGHT WINDS
ACROSS THE CSTL/OFSHR WTRS. HI PRES RIDGING WILL PERSIST OVER THE
NT2 AREA THRU THE ENTIRE FCST PRD. A WARM FNT WILL PASS NW OF THE
NT1 WTRS LATER TODAY AND TONITE. A SERIES OF LOW WILL PASS N OF
THE NT1 AREA TUE AND WED. A WEAKENING COLD FNT WILL MOVE SE AND
APRCH THE NT1 AREA THU...THEN DSIPT NEAR THE MAINE COAST THU NITE.

MODELS...THE MED RNG MDLS ARE IN GUD OVERALL AGREEMNT THRU THE
FCST PRD...EXCEPT THE NOGAPS BECOMES AN OUTLYER SOLN WITH THE
POSITION OF THE RIDGE ON FRI AND FRI NITE. ALSO THE GFS 30M LOOKS
OVERDONE WITH THE SW FLOW IN THE GULF OF MAINE ON WED...THEN AGAIN
ON FRI AND FRI NITE. WILL USE THE REPRESENTATIVE GFS 10M SOLN TO
POPULATE THE WIND GRIDS THRU THE FCST PRD. AM NOT PLANNING TO MAKE
ANY SIGNIF CHANGES TO THE CURRENT FCST TREND.

.SEAS...THE MULTIGRID WAVEWATCH III MDL INITIALIZED WELL OVER THE
OFSHR ZONES...EXCEPT ITS SEA HTS LOOK OVERDONE BY A FT OR TWO IN
THE GULF OF MAINE. THE ECMWF WAM IS VRY SIMILAR TO THE MWW3
MDL...EXCEPT WITH SLIGHTLY HIGHER SEAS. SO WILL BE USING THE MWW3
GUIDANCE THRU THE FCST PRD...BUT TAKING THE SEA HTS DOWN A NOTCH
IN THE GULF OF MAINE.
