Summary...latest avail ascat passes from 1431z to 1435z showed light winds across the wrn nt2 wtrs...with highest winds up to 20 kt over the srn nt2 zones. A high pres ridge will persist over the nt2 area thru the fcst prd...while gradually weakening. A weak cold front will move se and aprch the Gulf of Maine today...then dsipt near the coast tonight. A warm front will lift NE across the nt1 wtrs late Mon into Tue. A series of lows will pass N of the nt1 area Tue into Thu. A dissipating cold front will move se into the Gulf of Maine Thu nite. Another warm front will pass NW and N of the nt1 area on Fri and Fri nite.
Models...the 12z Med rng mdls are in vry gud agreemnt across the cstl/ofshr wtrs into Thu...so the representative 12z GFS 10m soln will be used to populate the wind grids for this timeframe. Given that it has better support from the 12z UKMET and latest wpc Med rng fcstr guidance concerning timing of the main ftrs N of 40n...the 12z ECMWF will be used for late Thu thru Fri nite.
.Seas...Diffs btwn the 12z wavewatch iii mdl and 12z ECMWF wam are mainly minimal (1 to 2 ft) during the fcst prd...so will use a 50/50 blend of the 12z wavewatch iii/ECMWF wam for tonite thru Fri nite to smooth out these diffs.
.Extratropical storm surge guidance...N/A.
.Nt1 New England waters... None.
