.SYNOPSIS...

Atlantic high pressure will extend across the Florida peninsula
through midweek as a weak surface trough settles over the
southeastern states. This weather pattern will create prevailing
south to southwesterly winds, with evening wind surges bringing
speeds up to Caution levels over the outer waters. A front will
stall near the local waters late this week into the holiday weekend,
with waves of showers and thunderstorms. Monitor the latest National
Hurricane Center outlook for potential tropical low pressure
development along this front late this week and into the upcoming
weekend.
