marine weather discussion for N Pacific Ocean NWS ocean prediction center Washington DC 119 PM PST Thu Dec 14 2017
.Forecast discussion...Major features/winds/seas/significant .Weather for the North Pacific N of 30n and E of 150w.
Models in the earlier periods remain consistent and in good agreement. High pressure remains to the west of the waters. As a coastal trough strengthens and the high pressure moves S and strengthens, models all indicate gales. The 12z ECMWF appears to have the most reasonable solution to this with the 12z GFS indicating a relatively large area of gales. Later in the forecast period, a cold front will move into the waters. Models are a a bit inconsistent here; however, the GFS and UKMET have trended towards a fairly unified solution and more toward the slightly slower ECMWF. The GFS is a bit bullish with the cold front, so will populate with the 12z GFS through 00z Sat, then use the ECMWF. Will edit the grids as necessary to better bring the winds into better consensus.
.Seas...Models initialized well. Will populate with the corresponding wave models to the wind models and will make edits as needed.
