Marine Weather Discussion for N Atlantic Ocean
NWS Ocean Prediction Center Washington DC
959 AM EST Mon Nov 19 2018

.FORECAST DISCUSSION...Major features/winds/seas/significant 
.weather for the North Atlantic Ocean W of 50W from 30N to 50N.

Developing inland low pressure will pass over the northern 
waters and allow winds to be elevated over the northern waters in
the short term. Another low pressure will pass over the northern
waters and elevate winds again in the extended period. NCEP 
weather map has low pressure over the mid Atlantic states while 
high pressure 1026 MB lies just east of the Baltimore Canyon. 
Pressure gradient is fairly relaxed but low pressure will develop
over the southeastern states and track northeast and that will 
tighten the pressure gradient over the waters and winds will be 
elevated especially over the central waters.

Seas are are quite small ranging between 2 and 5 ft across the 
forecast waters. Both NWW3 and ECMWFWAVE models fit well the 
observations and have been quite consistent. Models agree on 
building seas over the central waters but have small differences
on the areal coverage in areas with higher winds. Will not 
deviate much from the previous forecast solution and will 
therefore retain a 50-50 blend.

Global models GFS/CMC/ECMWFHR/UKMETHR have initialized well the 
surface observations with just minor differences on the position 
of the low pressure over the mid Atlantic states. In the short 
term, models differ slightly again on the strength of the winds 
over the central waters. Models also have slight variation on the
next round of gales over the northern waters. Will keep 
consistency and retain most of the forecast winds.

-----------------------------------------------------------------
PREVIOUS DISCUSSION...

Over the short term, ASCAT overpasses between 0040Z and 0220Z
last evening indicated winds up to 20 kt over the waters with a
well-defined trough just off the SE U.S. coast near the west
wall of the gulf stream. High pressure is currently passing E of
the area. Low pressure will form around Long Island by 12Z or so
this morning, and then track NE over the New England waters 
during the day today with winds increasing up to 20 to even 25
kt near this system. Another low will form E of the Delmarva by
this evening, and track E and NE near the north wall of the gulf
stream tonight into early Tue. Most of the 00Z guidance now 
brings winds to marginal gale force near the low tonight and
early Tue, and we will go ahead and add gales to offshore zones
ANZ920 and 910 for tonight. This low and associated winds will
then move E of the waters during Tue as another low forms near
Cape Cod along a cold front. This low will track toward the E
and NE, and pass just E of the Gulf of Maine later Tue, with an
associated cold front pushing SE over the remaining New England
offshore waters as well as further S off the Mid-Atlantic coast.
Gales will likely develop near the low and then in the cold air
advection behind the front Tue night from the Gulf of Maine S to
Georges Bank and then NE NT2 waters, or similar to the past few 
OPC forecasts. Over the short term, we will use a 50/50 blend of
the previous grids and the 00Z first sigma level GFS winds today
into Tue, and boost winds 10-15 percent near the north wall of 
the gulf stream later tonight into Tue. As the low intensifies 
as it moves away from the Gulf of Maine later Tue into Tue night
we will adjust winds upward to gale force over the Gulf of 
Maine, with these gales expanding S to Georges Bank and the NE 
NT2 waters during Tue night or similar to the past few OPC 
forecasts. For Tue night we will blend in some of the stronger 
winds from the 00Z high resolution Warw model, with the previous
grids. Gales should move E of the waters later Tue night as the 
pressure gradient begins to weaken over the waters. Forecast 
confidence is near average over the short term.

Over the medium range, Wed through Fri night, we will remain
closest to the 00Z ECMWF as it has remained the most consistent 
of the available model guidance over this time frame. This will 
also keep hazards consistent during this time period, although
we will go ahead and add gales to the Gulf of Maine S into the
Georges Bank zones for Wed night with support from the 00Z GFS,
UKMET and Canadian models. We will then maintain the previous
gales for northern and eastern NT1 or New England waters and the
NE NT2 waters for Thu and Thu night in the strong cold air 
advection in the wake of a strong cold front still expected to 
cross the waters Wed night into early Thu, followed by strong 
arctic high pressure building SE toward the area from the Great 
Lakes. The gales will then slowly shift E of the waters early 
Fri as the high builds toward the southern New England coast. The
next major weather feature to impact the region will be low 
pressure forecast to develop near the gulf coast by later Fri, 
and then track NE into the SE U.S. Fri night as the high pressure
area crosses the New England and northern Mid-Atlantic waters.
The 00Z models then diverge regarding the track of the low for 
the upcoming weekend with the 00Z ECMWF now well inland, the GFS
further E and slower, the UKMET further W and slower, and the 00Z
NAVGEM further E and faster. The 00Z Canadian model appears to 
be the closest to a middle of the road solution, and it is also 
fairly close to the latest WPC medium range guidance. Therefore, 
we will populate grids for Sat through Sun night with the 00Z 
Canadian guidance, and for now cap winds at 30 kt until better 
model agreement develops during the next few days, and we can 
better pin-point exactly where the hazards will occur.

All marine interests should closely monitor the latest OPC and 
coastal WFO forecasts during the next several days.

Seas...The 00Z Wavewatch, 00Z ECMWF WAM and previous grids
verified quite well when compared to the latest observations 
over the waters early this morning. For the early morning 
package, to best match the wind forecast, we will use a 50/50 
blend of the previous sea height grids and 00Z ECMWF WAM for 
today through Fri night, with some edits in and near the hazard 
areas and gulf stream to better match the wind forecast. For Sat
into Sun night, we will adjust sea heights manually and as we 
have capped the winds at 30 kt for now, we will cap sea heights 
at 13-14 ft to try to better match these capped winds for now. 
Additional adjustments to the forecast are likely over the next 
few days.

.EXTRATROPICAL STORM SURGE GUIDANCE...No significant positive 
surge is expected along the New England and Mid-Atlantic coasts 
during the few days. There is the potential for a more 
significant positive surge event developing by next weekend over
the region. Please closely monitor the latest OPC and NWS coastal
marine forecasts over the next few days.

.SYNOPSIS FOR NEW ENGLAND WATERS...Weak low pressure over today 
while pulling a developing cold front SE over the area. The 
front will move S of the area tonight into Tue as another low 
develops along the front and tracks NE, passing near Georges Bank
Tue. A third low will develop near Long Island Tue, track NE and
intensify as it moves NE from near Cape Cod late Tue. Low 
pressure will intensfy as it moves NE toward the Canadian 
Maritimes Tue night and a high pressure ridge will build E toward
the region. The ridge will cross the waters early Wed. A strong 
cold front will approach from the NW late Wed, then pass quickly 
SE over the waters early Wed night. A large arctic high pressure 
area will build SE from the Great Lakes toward the New England 
coast Thu and Thu night, and drift SE over the waters Fri and Fri
night.

.SYNOPSIS FOR MID ATLC WATERS...A low pressure trough along the
coasts of Georgia and the Carolinas will persist today. Weak low
pressure will form N of the waters and move NE over the New 
England waters later today, with a secondary low forming along a 
developing cold front E of the Delmarva. The secondary low will 
move E and NE over the N waters tonight into Tue, and pull a 
trailing cold front SE over the central and S waters. The low 
will then intensify and move NE away from the waters by Tue night
with the front clearing the S waters late Tue night. High 
pressure will build over the SE states early Wed, and then weaken
later Wed as a strong cold front approaches from the NW. The 
front will pass SE over the area Wed night and early Thu. Strong 
high pressure will build SE toward the Mid-Atlantic coast Thu 
night, and drift SE over the N waters Fri and Fri night. 
Developing low pressure is expected to approach the S waters from
the SW Fri night.
