marine weather discussion for N Atlantic Ocean NWS ocean prediction center Washington DC 326 am EDT Mon Aug 31 2015
.Forecast discussion: major features/winds/seas/significant .Weather for the North Atlantic ocean W of 50w from 30n to 50n.
The curr Sat img indc conv clds ovr the far S-wrn wtrs with dense lightng strikes. The radar has indc strng tstms cells ovr the S-wrn parts. At 06z area of hgh pres continues to dominate the frcst region xcpt the S-wrn parts where inland trof still lies just W of the srn region. The pres grdnt is still very weak with Max obsvd winds reaching 15 kt. The latst ascat pass at 0124z had Max winds reaching 15 kt acrs the region.
An upprlvl ridge has coninued to dominate the region with just very little energy embdd in an upprlvl trof barely toching the nrn wtrs. There is still some locally indcd energy also inland W of the srn wtrs slated to shift into the wtrs in the short term...already impacting the S-wrn wtrs. This enrgy will be so little that an upprlvl ridge will sweep it east and the region will again remain with almost no energy and will be like that in the xtndd prd. Since there are no indc of sig enrgy that will force chngs to the curr synop senario...shud continue with meagre wx ovr the entire fcst wtrs.
The glbl mdls are still in gud agrmnt in the short term and they hv just mnr diffs in the xtndd prd but that will not chng the synop pattern. Will continue fcst with GFS. In the short term hgh pres will remain ovr the region with very slck pres grdnt and so winds wil remain below gale force threshold thru the fcst prd.
.Seas...The seas are are small peaking at 6 ft ovr the far srn wtrs and the far ern parts of the Hatteras cnyn. Elsewhere seas range btwn 2 and 5 ft. Both nww3 and ecmwfwv mdls fit well with the obsvd seas pattern and hv been quite consstnt and so will continue with wna.
.Extratropical storm surge guidance...N/A.
.Nt1 New England waters... None.
.Nt2 mid Atlc waters... None.
