GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 845 Pm Edt Sun May 19 2019
Synopsis..High pressure will continue through the week with dry conditions expected over the waters. East to southeast flow will prevail, but winds will take an onshore westerly component during the afternoons as the sea breeze develops near the coast. Winds will increase late in the week and this will help to keep the sea breeze pinned closer to the coast. Overnight easterly surges will also begin by the middle of the week leading to winds approaching cautionary levels.

Vfr conditions with light winds this evening, tonight
and through Monday morning.

Prev discussion issued 244 pm edt Sun may 19 2019
short term (tonight-Monday)...

high pressure will continue to ridge across the area at the
surface as a frontal boundary stalls just to the north of
the state. Aloft, an upper low over the state shifts east to
over the atlantic as upper ridging starts to build from the
west. Light E SE flow will give way to an afternoon sea
breeze Monday, with isolated to scattered showers possible,
highest chances south. Lows tonight will be in the upper 60s
to lower 70s. Highs Monday will mainly be in the lower 90s.

Long term (Monday night-Sunday)...

large scale upper level troughing over the western u.S.

Will support strong downstream upper level ridging over the
southeastern u.S. And florida through the coming week and
into the upcoming memorial day holiday weekend. A dry
subsident air mass under the building upper ridge will
support mainly rain-free conditions across the forecast area
through the period along with hot and muggy conditions,
with surface high pressure from the atlantic extending
southwest across the northern peninsula supporting a light
easterly wind flow with an onshore sea breeze component
developing along the coast each afternoon through Tuesday.

The easterly flow will increase Wednesday through Friday as
the surface high to the north gets reinforced with a
easterly surge near cautionary levels possible during the
evening and overnight hours. Temperatures will run above
normal with overnight lows in the upper 60s to the lower
70s, with daytime highs climbing into the lower 90s along
the coast, and mid to upper 90s inland, with some inland
areas possibly approaching 100 by the holiday weekend.

Marine...

high pressure will ridge across the waters through the
period. Winds will be from the E se, and turning onshore
near the coast each afternoon through around mid-week. Flow
will then be increasing through the end of the week and even
approach headline criteria in evening easterly surges, so
will be watching for that.

Fire weather...

conditions will be becoming dry and hot for the end of the
week, with afternoon humidities approaching critical
levels. Currently no critical humidities forecast though,
and no other factors of concern.

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.
