Marine Weather Discussion for N Atlantic Ocean
NWS Ocean Prediction Center Washington DC
1007 PM EDT Sun Jun 24 2018

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

The latest NCEP surface analysis shows a weak frontal boundary
across the nrn and central offshore waters, and the infrared
satellite imagery along with the lightning density product
indicates some scattered showers and tstms along the boundary
mainly in the unstable environment over the Gulf Stream in NT2.
Ascat wind retrievals from this morning indicated winds up to 30
kt ahead of the front in nrn NT2 over the Gulf Stream, and
current wind observations show winds up to 25 kt with the highest
winds in the southerly flow ahead of the front. The 18Z GFS are
initialized well when compared with the data, and the model
indicates that the front will weaken early tonight. The model
also shows a low currently over New England will move E over the
area tonight into Mon while pulling a cold front over the waters
tonight into Tue. The GFS indicates the system will increase the
winds to 25 kt in the SW flow ahead of the front, and then to 30
kt in the Gulf of Maine in the northerly flow to the W of the low
center. The GFS is in good agreement with the 12Z ECMWF on the
overall track, timing, and intensity of the system, so not
planning on making any major changes to the grids with this
system as the previous forecast was based on the GFS.

The biggest forecast problem continues to be focused on a low
that the 12Z ECMWF shows moving off the SE coast Tue night into
Wed, then develops it while moving NE across the offshore waters
Wed into Sat. There is quite a bit of spread on this solution in
the global models as the 12Z/18Z GFS both indicate a much weaker
low to the W, and is similar to the 12Z UKMET. The 12Z GEM is
similar to the ECMWF on Wed, but then slowly diverges as a faster
and weaker solution. There is only a very weak symbol in the GEFS
ensemble members, a slightly stronger signal in the Canadian
ensemble, and a very strong signal in the ECMWF ensemble. As a
result, confidence is on the below average side as a result of
the poor support, and the latest WPC medium range guidance is
closer to the GFS solution. Since the previous forecast was based
on the 12Z GFS, am not planning to make any major changes in the
update package as the 18Z GFS has not changed much from the
previous run. Otherwise, confidence is well below average on any
sustained winds 34 kt or greater in the offshore waters as a
result of the poor model support, so will continue to carry no
warning headlines in the update forecast package.

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

Current Conditions...The 12z surface analysis shows a cold front
extending across the southern nt1 waters, then becoming a
stationary front near the Cape May region. The analysis also 
shows a low pressure trough approaching the mid Atlantic coast 
from the W, with high pressure ridging over the SE part of the 
nt2 area. The fronts are combining with the ridge to produce 
brisk SW flow over the northern and central nt2 waters S and E of
1000 fathoms. Latest available ascat and ascat hi-res passes 
from a few hours show 20 to 30 kt across the northern/central 
outer nt2 zones, 15 to 20 kt winds over the inner zones off the 
Carolina coast, and 5 to 15 kt winds elsewhere across the 
remaining offshore waters. Lightning density product data at 
1850z shows a line of scattered showers and tstms just S of the
cold front, which extends NE to SW across the northern nt2 
waters. The lightning density product also shows scattered
showers and isolated tstms over the outer southern nt2 waters.

Models/Forecast...The 12z medium range models are in very good 
overall agreement across the offshore waters through Fri night,
except the models have fallen into two opposing camps regarding a
low that is expected to form near the South Carolina coast Tue
night, with the 12z ecmwf/cmc taking the low NE across the
offshore waters Wed through Fri while strengthening it
significantly but the 12z gfs/ukmet keeping the low near the
Carolina coast as a weak system. For now will use the 12z gfs 
10m/30m solution with the stability smart tool for the wind 
grids through the forecast period, since it looks like a
representative model solution that provides continuity with the
previous grids. Am not planning to make any significant changes 
to the current forecast trend at this time.

Seas...The 12z wna wavewatch and 12z ecmwf wam both initialized 
well over the coastal and offshore waters versus the latest buoy 
observations and altimeter data. The models are good agreement 
for tonight through Tue, then diverge starting Tue night as the 
atmospheric models start to show noticeable differences. The 12z 
wna wavewatch will be used over the entire forecast period, in 
order to be consistent with the preferred 12z gfs wind grids.

Extratropical Storm Surge Guidance...N/A.

.WARNINGS...Preliminary.

.NT1 New England Waters...
     None.

.NT2 Mid-Atlantic Waters...
     None.

NWS Ocean Prediction Center Washington DC
429 PM EDT Sun Jun 24 2018

New England continental shelf and slope waters from 25 nm
offshore to the Hague Line, except to 1000 fm south of New
England.

Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.

429 PM EDT Sun Jun 24 2018

.SYNOPSIS FOR NEW ENGLAND WATERS...A cold front extending NE to 
SW across the southern waters will shift E of the area this 
evening, as low pressure approaches the coast from the W. The 
low will strengthen and move E over the Gulf of Maine tonight 
into Mon, with an associated cold front passing SE over the 
waters. A high pressure ridge will slowly build SE toward the 
area late Mon and Mon night, cross the waters Tue through Wed, 
then pass SE of the area Wed night. A cold front will approach 
the region from the W Thu and Thu night, then move E across the
waters Fri and Fri night while weakening.

.SYNOPSIS FOR MID ATLC WATERS...Low pressure will pass N of the
area this evening and tonight, then move off to the NE and 
intensify Mon. A cold front associated with the low will move SE 
over the waters tonight and Mon, then stall over the southern 
waters Mon night into Wed as weak low pressure forms along the 
front near the South Carolina coast by Tue night. A high pressure
ridge will build SE into the northern waters Tue, move E over 
the area Tue night and Wed, then shift E of the waters Wed night.
The low is expected to drift N along the coast Wed into Thu, as 
a cold front approaches from the W. The cold front will move
offshore into the mid Atlantic waters Thu night, then move E
across the area Fri and Fri night while weakening.
