.SYNOPSIS...
High pressure situated along the southeastern seaboard will
gradually weaken and shift southeastward through Friday night.
Southeasterly winds will increase across the near shore waters each
afternoon through Saturday behind the inland moving Atlantic sea
breeze, with winds shifting to southerly during the early evening
hours and then southwesterly after midnight. A frontal boundary will
sink into the southeastern states by Saturday evening, with isolated
showers and thunderstorms possible on Saturday afternoon ahead of
this boundary. Widely scattered showers and thunderstorms will be
possible on Saturday night and Sunday as this front stalls near the
Georgia waters. This front will then lift northward early next week
ahead of another front that will approach our local waters towards
the middle portion of next week.
