A frontal boundary will stall over the southeastern states today, with prevailing offshore winds this morning becoming onshore towards noon over the near shore waters as the Atlantic sea breeze pushes inland. Scattered showers and thunderstorms will possibly develop over our local waters late this afternoon and early this evening. Outside of thunderstorm activity, southerly winds will briefly surge this evening before shifting to southwesterly while diminishing overnight. Southwesterly winds will prevail on Wednesday and Thursday ahead of another weakening frontal boundary that will stall and dissipate to the northwest of our local waters by Friday, with increasing chances for showers and thunderstorms, mainly during the afternoon and evening hours. Prevailing winds will become southeasterly by the weekend as the axis of Atlantic high pressure briefly lifts northward, with another frontal boundary then expected to enter the southeastern states early next week, which will shift prevailing winds back to southwesterly. .GULF STREAM...
