.Forecast discussion: major features/winds/seas/significant

.Weather for North Atlantic ocean W of 50w from 30n to 50n.

Low pres currently E of the nt2 waters will move slowly NE today

and tonight. N to NE winds up to 25 kt will continue across

portions of the srn and central nt2 waters into tonight. Strong

high pres will then build N of the nt1 waters sun. Weak low pres

is still expected to form across the srn nt2 waters Sun

night...then track NE across the offshore waters through Wed.

The latest runs of the NAM and GFS are in reasonable agreement

and continue the idea of the last couple of model runs in having

somewhat weaker winds across the offshore waters. The

Canadian...meanwhile...continues to be a strong outlier. For now

will continue with previous forecast of showing Max winds of 30

kt with this system as it moves NE. A cold front will then move

into the offshore waters by Thu.

The wavewatch model looks reasonable and will be followed fairly

closely during the forecast period. The E swell which wavewatch

iii brings into nern nt2 waters as well as Georges Bank sun

ngt/Mon appears reasonable as global models all indicating

decent E to NE fetch N of W Atlc cold front.

subject to change. Any changes will be coordinated through AWIPS

12 planet chat or by telephone.
