Shwrs will be isold to sct msly across the N late this aftn into erly eve as the warm sector reaches its max nwrd progress. In fact, temps will cont to rise across most of the Rgn well into the eve as strong llvl thermal advcn conts. Based on sfc obs, we kept a mention of patchy marine fog into the eve, but this should be slowly driven offshore as llvl winds slowly become more wrly component. Speaking of sfc winds, they should cont to increase into the eve as the sfc pres grad and winds alf increase. Wind adv wind gusts are most likely with prefrontal shwrs xpctd later this eve into the ovrngt, and with the immediate passage of the cold front late tngt. The best potential of additional rnfl from shwrs will be across the NW hlf of the Rgn tngt where the best mid and upper lvl dynamics will be and where there may be enough instability alf ahead of the cold front for isold tstms. Shwrs will exit the FA after the passage of the cold front late tngt, followed by a rapid erly morn temp fall. Mon will see little recovery with hi temps with a brisk NW wind with ptly to msly sunny skies Cntrl and Downeast and ptly to msly cldy skies N.

NEAR TERM: Will cont with outer MZ gale wrng and inner bay/harbor MZ SCA hdlns. Outer MZs will need to be converted to an SCA erly Mon morn upon the ending of the gale. Otherwise we added areas of fog to our waters this eve based on latest buoy obs, with fog becoming patchy late tngt as sfc winds become wrly component, with all fog dissipating by Mon morn as sfc winds become offshore behind a strong cold front. Kept close to a WW3/NWPS blend for fcst wv hts with the primary wv pds in the 5 to 7 sec range. SHORT TERM: Have used the NAM for sustained winds through Wednesday then transition to the Super Blend Winds. For Waves: The primary wave system Tuesday will be longer period southerly swell with a secondary northerly wind wave. Southerly wind wave will then become the primary wave group for Wednesday and Thursday. Will use the Nearshore Wave Prediction System for waves.
