GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 956 Am Edt Sat Aug 19 2017
Synopsis..Surface high pressure will remain across the region through the weekend with light winds and slight seas. Winds are expected to increase some with easterly surges early next week as the pressure gradient tightens a bit 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.

Short term (tonight - Sunday)
In the mid upper levels, an upper level low over the eastern gulf of
mexico will continue moving westward toward texas through the
weekend. Mid-level ridging near bermuda extends west-southwest over
eastern florida. On the surface, subtropical high pressure near
bermuda ridges west-southwest over florida and into the gulf of
mexico. This will produce a predominant easterly wind flow over the
florida peninsula on Sunday. This will favor the development of
thunderstorms early in the afternoon along the east coast and late
evening along the west coast of florida as the storms move westward.

Temperatures will remain around seasonal averages with daytime highs
in the low 90's and overnight lows in the mid to upper 70's.

Long term (Sunday night - Saturday)
A tropical wave will be exiting to the west into the gulf of mexico
early on Monday. Lingering moisture associated with the wave along
with the sea breezes will support scattered showers and storms over
the region on Monday with pops in the 20 to 40 percent range.

Thereafter models show drier air over the atlantic advecting in over
the forecast area during Monday night and Tuesday in the wake of the
wave which will result in lower rain chances (pops 20 to 30 percent)
across the forecast area on Tuesday, especially across central zones
where the driest air will be most prevalent. Another tropical wave
will approach and move across the region and into the gulf during
Tuesday night into Wednesday. Increasing moisture (pw's increasing
to 2+ inches) associated with this wave will again increase rain
chances across the area during Wednesday and Thursday with scattered
to numerous showers and storms expected each day. The high moisture
content combined with slow moving storms will favor locally heavy
rainfall amounts in some locations.

During Thursday night into Friday an upper level trough and
attendant cold front to the north will push the surface ridge axis
to the south to lie across the southern peninsula. With ample
moisture remaining in place along with the sea breeze and troughing
aloft scattered to numerous showers and storms will continue through
the period. The onshore flow will favor late night and early morning
showers and storms along the coast with the convection then moving
to inland areas during the afternoon.

On Saturday the upper level trough axis will shift east into the
atlantic as upper level ridging noses in from the northwest as the
surface ridge axis lifts back to the north some with scattered to
numerous diurnal sea breeze driven showers and storms expected
during the afternoon. It will remain very warm and muggy with
temperatures running some 3 to 5 degrees above normal through the
period. Overnight low temperatures will range from the mid 70s
inland areas, to the upper 70s to around 80s along the coast, while
daytime highs will climb into the lower 90s along the coast, and mid
to upper 90s inland with the high humidity levels supporting heat
indices in the 100 to 105 degree range each afternoon.

Aviation
Vfr conditions can be expected through much of the day with drier
mid to upper levels. Will cover any isolated storms with vcts this
afternoon with localized and brief restrictions possible from 18z-
21z. No other aviation impacts expected.

Marine
High pressure in the gulf of mexico will influence the weather over
the coastal waters tonight and into early Sunday. Winds will remain
light out of the north tonight, then veering to the east on Sunday
afternoon as high pressure near bermuda ridges west over the region.

This will be the dominant weather feature through the period. With
the easterly flow, showers and storms will be more common later
evening and into the early morning hours each day. The main hazard
will be dangerous lightning, locally higher winds and choppy seas
near thunderstorms.

Fire weather
Abundant moisture combined with daily rain chances will keep
humidity levels above critical levels through early next week with
no fire weather issues expected.

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.
