Synopsis..Weak bermuda high pressure will remain across the region through the weekend with light winds and slight seas. Winds are expected to increase with easterly surges early next week as the pressure gradient tightens between low pressure to the south and high pressure to the north. Otherwise, the primary marine concern will be daily scattered Thunderstorms which may produce dangerous lightning, locally stronger winds and choppy seas.

A few strong storms possible this afternoon...

Update
A large upper level low located over north-central cuba
with a trough axis extending north into the florida
peninsula this morning will continue to move slowly to the
west the remainder of today. Water vapor imagery as well as
12z mfl RAOB data shows drier and cooler mid level air
associated with the upper low advecting into southern
portions of the peninsula early this morning where pw's at
mfl has dropped to 1.46 inches with 500mb temperatures now
at -9c. This drier and cooler mid level air may lead to some
some strong convection developing along the sea breeze
across southwest florida during the afternoon hours with
strong downburst winds and small hail being the main hazards
along with frequent lightning strikes and heavy rain.

Further to the north across central and northern portions of
the forecast area deep layered moisture (pw's 2+ inches and
milder mid level temperatures will again support scattered
to numerous showers and storms developing along the sea
breeze and outflow boundaries during the afternoon with a
very weak steering flow through 700mb again supporting slow
and erratic storm motion with some very heavy rainfall
amounts possible in some locations along with frequent
lightning strikes and some gusty winds. Given the cooler
drier air aloft will add gusty winds and hail wording into
the forecast for southwest florida for the afternoon, and
will also add heavy rain and gusty winds wording for central
and northern zones given the high pw's and slow and erratic
storm motion. Other than these minor tweaks no other changes
are planned at this time. Zone update will be out by 10 am.

Aviation
Brief MVFR CIGS vsbys may impact the terminal sites after
16z as scattered showers and thunderstorms develop along
the bay and sea breeze boundaries and have included tempo
groups to cover this. Outside of the convectionVFR will
prevail. Light and variable winds early this morning will
become west to northwest at 7 to 9 knots after 16z as the
sea breeze develops and moves inland with gusts up to 30
knots possible in the vicinity of tsra. Light to calm winds
will return to all terminals after 02z tonight.

Marine
High pressure from the atlantic extending west across the
central florida peninsula and into the eastern gulf will
maintain light winds and slight seas over the gulf waters
the remainder of today with a weak pressure pattern
supporting an onshore sea breeze component developing along
the coast during the afternoon. Wind and seas will be higher
in the vicinity of thunderstorms, otherwise no headlines
are expected. Ongoing forecast is on track with no changes
expected in the next forecast issuance around 10 am this
morning.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
