Scattered afternoon and evening showers and Thunderstorms will be possible on Wednesday as prevailing winds briefing shift to northwesterly. Coverage of showers and Thunderstorms will then decrease by Thursday as the frontal boundary dissipates, with only isolated to widely scattered late afternoon and early evening activity possible for the near shore waters through Friday as a prevailing westerly flow continues during the overnight and morning hours each day. Surface troughing developing over the southeastern states this weekend could bring scattered afternoon and evening showers and Thunderstorms to our local waters as offshore winds prevail.
