Surface high pressure extends across most of the Florida peninsula
with a broad surface low north of Puerto Rico. Northeasterly to
easterly surface and low level flow will continue to bring patches
of moisture/cloudiness across the Atlantic waters with embedded
showers. Additional shower activity is possible from streamers
moving westward off the northwest Bahamas islands.
Forecast for today through Tuesday...
A broad surface low north of Puerto Rico is forecast to slowly
deepen and move north slowly over the next day or two, with the
global models in general agreement with this scenario. This
scenario should keep South Florida under a surface ridge, with an
upper level ridge forecast through the early part of the week, and
there will not be any deep moisture available with forecast
PWAT`s around 1 inch for most of this period. Forecast soundings
indicate generally easterly to northeasterly surface and low level
winds with plentiful low level moisture. Therefore, some passing
showers will impact the Atlantic waters and eastern peninsula from
time to time, with Bahamas streamers potentially adding
additional showers. In addition the Gulf coast sea breezes are
expected each afternoon with a few showers across the western
interior regions and Naples metro areas in the late afternoon and
Forecast for mid to late week...
There is general agreement amongst the global models that by mid-
week surface high pressure is forecast just east of the northwest
Bahamas and extends across central and South Florida with an
upper level ridge across the eastern Gulf and Florida peninsula.
Generally stable weather is forecast with guidance trends
indicating temperatures could climb into the upper 80`s across the
interior peninsula, with lower 80`s forecast across the Gulf and
Atlantic metro areas. Similarly for Thursday, but by Friday a cold
front is forecast to enter the eastern Gulf and Florida
panhandle, with regional southerly winds and temperatures possibly
climbing a couple more degrees.
The extended global models indicate the aforementioned front could
sink southward into central Florida or even South Florida, with
some shower activity as a result although not indicated in the
A pre-cautionary statement is necessary early this morning for the
Atlantic and Gulf Stream waters with winds in the 15 to 20 knot
range, with seas from 3 to 5 feet. Winds and seas are expected to
slowly subside today into Monday and continue subsiding into
Tuesday. Through the extended forecast, no hazardous seas are
forecast and regional winds currently not forecast to approach or
exceed 20 knots.
Atlantic showers continue to cause bouts of MVFR conditions at the
east coast terminals overnight. Gusty easterly wind expected
through much of the period, though a Gulf sea breeze could form
later today and push through APF with an increasing chance of
showers for the Gulf coast as well. Potential window for
improvement at the east coast terminals by late afternoon.
A high risk of rip currents will continue across the Atlantic
beaches early today and the current high risk may be dropped to a
moderate risk with more data gathering later today. A slight to
moderate risk of rip currents across the Atlantic beaches is
expected by Monday and for Tuesday as winds and seas continue to
