.SYNOPSIS...
Atlantic high pressure centered near Bermuda will weaken and shift
southward later today and tonight. A frontal boundary will then
enter the southeastern states on Friday night before stalling to the
north of our waters during the weekend. Light southerly winds this
morning will become onshore early this afternoon as the Atlantic sea
breeze shifts inland, with breezy conditions developing by late this
afternoon across the near shore waters. Winds will then shift to
southerly early this evening and will surge to near Caution speeds
throughout our local waters. Unseasonably dry weather will otherwise
continue through Saturday. Prevailing winds will become westerly on
Friday morning, followed by breezy southeasterly winds developing by
late afternoon. Southerly evening wind surges are forecast this
weekend. Scattered afternoon and evening showers and thunderstorms
are then expected each afternoon and evening beginning on Sunday,
with some potential for stronger storms across the Georgia waters
early next week as another frontal boundary pushes into the
southeastern states.
