Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
744 PM PST Sun Dec 9 2018

.FORECAST DISCUSSION...Major features/winds/seas/significant 
.weather for the North Pacific N of 30N and E of 150W.

Cold front cas per 00Z NCEP analysis is currently moving onshore
Washington and Oregon with the weakening trailing portion
extending across the northern and central PZ6 waters. Coastal
observations indicate gales noted in last ASCAT passes near the
coast have ended but stronger winds, possible gales, noted to the
N near the Queen Charlotte Islands as the low associated with the
front moves into SE Alaska.

Further down the line, no big changes are noted in model 
guidance through Thu night, but differences remain in the 
northern offshore waters for Thu and Thu night. Did blend 50/50
the previous grids with the new 18Z GFS through Tue as the model
consensus supports expanding the prefrontal gales with the next
front S into the next tier of PZ5 zones. The other change is to
update the grids for Thu and Thu night with the new 18Z GFS
blended 50/50 with the stronger 12Z ECMWF as that model blend
appears to fit the middle of the guidance.

SEAS...Latest wave guidance within a foot or two of current
observations over the coastal and offshore waters when compared 
to latest surface observations. In line with changed in wind 
grids noted above, blended previous wave grids 50/50 with the 
new 18Z Wavewatch through Tue and then Thu and Thu night updated 
with a 50/50 blend of the newer 18Z Wavewatch with the 12Z ECMWF 
WAM. No other significant changes to the wave grids are expected 
at this time.
-----------------------------------------------------------------
PREVIOUS DISCUSSION...

12z global model guidance in good agreement into Thu, with
differences noted thereafter. For the wind grids, will lean
towards 12z GFS through 12z Thu, then go with a 50/50 blend of
the GFS and the ECMWF after 12z Thu, through the remainder of the
forecast period to Fri night.

Guidance in good agreement with timing and strength of frontal
boundary to affect northern offshore waters late Mon and Mon 
night. Model consensus still showing gale to near gale conditions
in the southerly flow ahead of the boundary. GFS and Canadian a 
bit further south with gales than both the ECMWF and the UKMET. 
Will limit gales to the far northern PZ5 zones, which is in 
agreement with the previous forecast. Confidence in gales is
moderate to high for this system. 

Models continue to show a brief surge of cold air advection
moving into the northern offshore waters behind the cold front 
late Tue and Tue night. Did boost 10m winds by 10 percent in the 
strongest west to northwesterly winds behind the front due to 
instability caused by the cold air advection. This will allow for
gales to move into the northern offshore waters during this time
period, which is in line with the previous forecast. Confidence 
in gales is moderate at this time.

Next cold front expected to approach the northern offshore waters
Wed, and move into the region Wed night and Thu. Latest model
guidance continues to show gales in the southerly flow ahead of
the front, with some models showing winds up to 45 kt possible.
Will limit winds to 40 kt for this package. Front stalls near the
far SE portion of the PZ5 waters later Thu, then moves N as a
warm front Thu night into Fri as an area of low pressure
approaches.

Models then diverge with track of the low pressure system, with
the ECMWF being the more northern track and takes it through the
northern PZ5 waters, while GFS/UKMET/Canadian take it a bit
further south across the southern PZ5 and northern PZ6 waters.
Very low confidence in this portion of the forecast due to model
uncertainty, so will favor a 50/50 blend of the ECMWF and GFS for
this system, which is surprisingly similar to previous forecast
trends. This will take the low across the northern offshore
waters Thu night into Fri. For the winds, Models in general 
agreement with gales for this system, but with so much 
uncertainty with the track of the system, will limit winds to 35 
kt for now. 

Yet another strong cold front is expected to approach the
northern offshore waters Fri night, but gales expected to be west
of the area by the end of the forecast period.

.SEAS...Latest wave guidance within a foot or two of current
surface observations across the coastal and offshore waters, but
still a bit underdone northwest of Vancouver Island where seas
still running around 21 ft at 18z. For the wave grids, will lean
towards the 12z ENP wave watch guidance through 12z Thu, then
use a 50/50 blend of the ECMWFWave and ENP for the remainder of
the forecast period through Fri night.

.SYNOPSIS FOR WASHINGTON AND OREGON WATERS...A low pressure
trough will lift N of the area tonight, as as a high pressure
ridge builds across the region from the SW tonight into Mon. A
warm front will lift NE across the region Mon night into Tue,
followed by a cold front moving through the area Tue into Tue
night. A ridge will pass quickly E across the area Wed, as a
strong cold front approaches the waters. The front will move SE
across the region Wed night and Thu, then will lift back N as a
warm front Thu night into Fri as an area of low pressure
approaches. The low will move NE across the waters late Thu 
night and Fri. Another strong cold front will approach the waters
from the W Fri night.
