.SYNOPSIS...

Prevailing southwesterly winds are forecast Today, with the
afternoon sea breeze potentially triggering isolated to widely
scattered thunderstorms through this evening, mainly for the
northeast Florida waters. Another frontal boundary will sink into
the Deep South late this week, with this feature becoming stationary
during the weekend. Strong to severe thunderstorms will be possible
well in advance of this front on Wednesday afternoon and evening
across our local waters.  Scattered to numerous thunderstorms will
continue across the northeast Florida waters on Thursday and Friday,
with less coverage currently forecast for the Georgia waters. Waves
of showers and thunderstorms will then overspread all of our local
waters during the upcoming weekend. Outside of expected thunderstorm
activity, southwesterly winds will prevail and will strengthen ahead
of the approaching front beginning towards midweek, with Caution
conditions likely through the upcoming weekend and periods of Small
Craft Advisory conditions possible.
