|GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 416 Am Edt Sun Jul 22 2018 |
Synopsis..A trough of low pressure to the north and a ridge of high pressure to the south will combine to produce increasingly westerly winds today...with small craft advisory level winds expected north of tarpon springs, and cautionary level conditions expected over the gulf waters between englewood and tarpon springs. Cautionary to advisory level conditions will continue through Monday, with winds and seas expected to subside Monday night through much of the week as the area of low pressure to the north of the waters dissipates.

Updated pops to lower them a little bit this morning across
the area due to the lack of coverage. The nature coast will
be our main area of concern today due to a cut off low over
the eastern half of the us that tend to send strong outflow
boundaries their way. Best chance for that today will be in
the evening and early overnight hours. For that reason i
have increase pops slightly in that area this evening and
mentioned the possibility of severe weather in the area.

generallyVFR conditions will persist through the forecast
period. We will remain dry for all TAF sites during the
morning hours but thunderstorm chances will be starting by
around 18z and will start north and move south. A shortwave
moving through will help to keep thunderstorm chances
through the overnight hours.

short term (today - Monday)...
a broad upper mid level trough of low pressure over the
eastern us is cut off from the main flow, causing it to
generally hold in place today and Monday while slowly
amplifying. The surface reflection is also sprawled across
the eastern us, and will gradually expand south into
northern florida today and tonight, increasing the pressure
gradient between it and the surface ridge across the
southern gulf, increasing the westerly flow. This breezy
onshore flow will cause a high risk of rip currents along
area beaches today and Monday.
Showers have been slower to develop over the gulf this
morning than in previous days, but with precipitable water
values remaining around two inches, scattered showers are
expected to expand in coverage over the eastern gulf through
sunrise and will continually move onshore through the
morning hours. As surface heating takes over through the
late morning and afternoon, scattered to numerous
thunderstorms will develop across the area once again. The
main area of concern will be over the nature coast, which
could see some stronger storms this afternoon and evening as
convection to the north of the area sends outflow
boundaries into the region. Damaging wind gusts will be the
primary hazard, but the possibility exists for training
storms moving onshore and causing high rain totals and
localized flooding, mostly along the coast of the nature
Tonight and Monday, the area of low pressure both at the
surface and aloft will extend farther south into northern
florida, with the breezy west wind continuing. Scattered to
numerous showers and thunderstorms will still be possible
overnight moving onshore from the gulf. A weak frontal
boundary associated with the advancing low pressure will
push the axis of highest moisture through the interstate 4
corridor during the morning and into southwest florida
during the afternoon, with numerous thunderstorms
Long term (Monday night - Saturday)... |
the mid level cutoff low over the southeastern CONUS and
northeastern gulf of mexico will gradually open up through
mid week and be absorbed into a trough swinging through the
great lakes during the second half of the week. At the
surface, the area of low pressure over northern florida will
gradually dissipate Tuesday and Wednesday, with the
subtropical ridge building back into southern florida from
the atlantic late in the week. This pattern will continue to
support light westerly to southwesterly flow through
Thursday, then more southerly flow Friday and Saturday as
the ridge builds in.
Through Thursday, this pattern will produce morning showers
and storms developing over the eastern gulf and moving
onshore, with scattered to numerous thunderstorms building
through the late morning and afternoon hours before
gradually dissipating through the evening. With more
variable flow Friday and Saturday, a more typical summer
pattern is expected, with mainly afternoon thunderstorms
developing across the area.
westerly flow will continue between a broad area of low
pressure over the southeastern states and a ridge of high
pressure across the southern gulf of mexico. As the area of
low pressure sinks farther south towards the eastern gulf,
wind speeds will increase to around 20 knots, producing low
end advisory level conditions today. Cautionary to possibly
advisory level winds will continue into Monday afternoon
before gradually subsiding Monday night as the pressure
gradient relaxes. West winds around 15 knots or less will
continue through the rest of the week. Otherwise, higher
winds and seas will be possible in daily showers and
thunderstorms, producing locally hazardous marine
relative humidity will remain well above critical thresholds
though the forecast period.

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.
