GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 342 Am Edt Thu Jun 22 2017
Synopsis..High pressure will continue to build into the florida peninsula through the day today as tropical storm cindy gradually moves away from the region. A period of cautionary winds and seas will continue for the offshore waters through this morning with improving conditions this afternoon. From tomorrow well into next week, high pressure looks to remain poised over the region, with light south to southeast winds shifting onshore near the coast each afternoon due to the seabreeze. During this timeframe, the only marine concern will be locally gusty winds and rough seas due to scattered marine Thunderstorms during the late afternoon and evening hours.

Aviation
Some MVFR visibilities with ifr lifr ceilings at the
terminals this morning with low clouds and patchy ground fog
in place. This will lift and dissipate by 14z, withVFR
conditions then prevailing through much of the rest of the
period. Only exception may be with scattered afternoon
thunderstorms in the 19z-02z window causing some brief MVFR
to ifr conditions. Light winds overnight.

short term (today and Friday)...

tropical storm cindy continues to approach the northwest
gulf coast, where it will make landfall early this morning
near the louisiana texas border region. Impacts from cindy
continue to be felt well to the east of the center of the
storm, with spiral bands of thunderstorms extending across
much of the gulf coast and well inland across the
southeastern u.S. This activity will generally continue
today as the system lifts northward toward the the lower
mississippi vally region. As cindy departs, surface high
pressure will gradually build in over the florida peninsula,
establishing a southeasterly flow pattern.

For today, expect similar conditions to yesterday. Much of
the morning and early afternoon will feature partly cloudy
skies with warm and muggy conditions. By mid to late
afternoon, surface heating combined with weak convergence
along the seabreeze will allow for scattered storms to
develop. The east coast seabreeze will gradually migrate
westward, with a seabreeze collision somewhere near the i-75
corridor late afternoon. This should lead to fairly
widespread convective coverage, as has been alluded to in
recent runs of the 3km NAM and hrrr. Storms may linger into
the evening hours for points north of tampa bay, eventually
migrating offshore tonight. Gusty winds and frequent
lightning will be the main hazards with any storms.

On Friday, despite a surface pattern normally favorable for
afternoon storms, a ribbon of dry mid level air will move
over the florida peninsula. This will bring modest
subsidence to the region, suppressing afternoon
thunderstorm development. Without much in the way of rain
and thunderstorm induced outflows, temperatures will likely
be a tick or two warmer than they have of late, and expect
most areas to reach the lower 90s. Isolated activity may
develop across mainly south florida, but this appears to be
a relatively low probability at this juncture.

Mid long term (Friday night - Thursday)...

a fairly typical summertime forecast can be expected for
much of the extended forecast period. To start the weekend,
surface ridge axis will shift slightly allowing for a sse se
wind flow to become established for the weekend. Some
lingering dry mid level air will help to suppress rain
chances a bit compared to what we might expect
climatologically from this flow regime. That being said,
this will be short lived as rain chances will begin to
increase Sunday and especially into early next week as an
upper level trough begins to encroach on the northern part
of the state. This will support fairly high pops (50-70
percent) for the first half of next week. Temperatures
throughout the period will be seasonal with highs within a
few degrees of 90 for the weekend with upper 80s more likely
Tuesday - Thursday with higher cloud cover rain chances;
overnight lows generally in the middle 70s daily, maybe some
lower 70s across the nature coast late in the forecast
period.

Aviation (06z tafs)...

light east to southeast winds to persist with prevailing
vfr conditions most terminals. Klal will see brief MVFR
ceilings on and off through sunrise... With lesser chances of
brief lowered ceilings elsewhere. Winds will become more
southerly late morning into the afternoon with isolated to
scattered thunderstorms developing along the seabreeze. This
activity may affect any terminal and will maintain vcts
from 19z on. Most activity will shift north of terminals by
00z with a return toVFR conditions thereafter.

Marine...

tropical storm cindy continues to shift westward, nearing
the louisiana coast early this morning. Breezy southeast
winds and increased seas will continue to support cautionary
conditions offshore this morning. As the storm continues
west, high pressure will build in over the eastern gulf.

This will allow winds and seas to improve by midday. Over
the next several days, high pressure will extend over the
waters with light south to southeast flow each day. The
seabreeze will shift winds onshore each afternoon with
scattered marine thunderstorms possible each day in the late
afternoon and evening hours. These could result in locally
rougher seas, frequent lightning, and gusty winds.

Fire weather...

over the next several days, high pressure will extend from
the western atlantic ocean into northern and central
florida. This will maintain low level east to southeasterly
flow and abundant low level moisture. This combined with
near daily opportunities for rain will prevent and fire
weather concerns through next week.

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.
