.SYNOPSIS...
A cold front moving across the southeastern states tonight will slow
its forward progress as it approaches our local waters on Friday.
Showers and thunderstorms will be possible on Thursday afternoon
and evening ahead of this front across mainly the Georgia waters,
where strong to isolated severe storms possible. The frontal
boundary will push across the Georgia waters after midnight on
Thursday night, stalling by Friday evening across the northeast
Florida waters. Widely scattered showers and thunderstorms will be
possible along this front on Friday afternoon, with an increasing
coverage expected this weekend through Monday. A round of strong
to isolated severe thunderstorms possible on Sunday afternoon and
evening, well in advance of another cold front that will be
entering the southeastern states. This front will sweep
southeastward across our local waters on Monday afternoon and
evening, accompanied by additional showers and thunderstorms that
will shift offshore on Monday night. Breezy northerly winds in the
wake of this frontal passage will shift to northeasterly by
Tuesday morning as high pressure builds into the southeastern
states, with Caution conditions likely and Small Craft Advisory
conditions possible through Tuesday afternoon.
