Marine Weather Discussion for N Atlantic Ocean
NWS Ocean Prediction Center Washington DC
318 AM EST Thu Feb 21 2019

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

There was a ASCAT and ASCATB passes at about 0130Z and 0240Z, 
respectively. The swaths were across central and southern areas
of the mid Atlc where max winds were to 30 kt with the strongest
winds over the inner mid Atlc offshore waters.

At 06Z high pressure ridge is centered just E of the offshore 
waters and will continue to move E of the area today. Low 
pressure was just E of the northern Delmarva coast early this 
morning while moving NE and turns more E and over the New England
waters later this morning while intensifying. At 06Z the 
associated cold front was along the mid Atlc coast and moves SE 
across the waters. Have not seen any observations showing gales 
force at this time, but with cold front pushing offshore likely 
will have some reports in advance of the front over the outer
mid Atlc waters. The cold front moves SE into the S mid Atlc
waters by later tonight and stalls becoming stationary from Fri 
into early Sat. A high pressure ridge build in across the 
central and northern offshore waters tonight and Fri and moves E 
over the area Fri night into Sat. By Sat the stalled front
returns to the N as a warm front with increasing southerly flow 
by Sun as strong low pressure moves NE over the Great Lakes.
Another low pressure eventually develops near the coast of inner
waters of the northern mid Atlc and New England coast Sun along
the front and moves NE. The UKMET/GEM/GFS and ECMWF are similar 
with a low pressure deepening and tracking along the New England
coast and then over the Canadian maritimes. The GEM/UKMET/ECMWF 
are showing strong cold air advection from Mon into Mon night 
across the New England into northern mid Atlc waters, although 
the ECMWF does not show as strong advection. Will favor the UKMET
and GFS with grids with this event and will stay with winds to 
45 kt. 

.SEAS...For seas will use a 50/50 blend of the WWIII and ECMWF
wam through 12Z Sun. Will then use the prior grids from 12Z Sun
into 00Z Mon and thereafter will use the 50/50 blend of the WWIII
and ECMWF wam from 00Z Mon through the end of the forecast
period.

.EXTRATROPICAL STORM SURGE GUIDANCE...Will favor the ESTOFS 
guidance for today. Otherwise will no surges over the waters 
during the next day or two. For more details please monitor the 
latest forecast and information from your local National Weather 
Service office.

and pass across the S waters this morning, and move E of the 
region by the afternoon. Another high will slowly build E toward
the coast Thu night into Fri night, move E over the waters Sat, 
and then pass E of the area Sat night as another intensifying 
developing low approaches from the SW. The low will track NE near
