GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 401 Am Est Thu Feb 22 2018
Synopsis..Strong high pressure will remain in place over the western atlantic and florida through the end of the week with southeast winds in the 10 to 15 knot range along with warm and dry conditions. The upper level high will weaken and shift west southwest into the gulf during the upcoming weekend with the attendant surface high sinking south to lie across the central waters. This will allow for lighter winds with an onshore sea breeze component developing along the coast each afternoon. Wind and seas should remain below 15 knots and 5 feet with no headlines expected.

Record high temperatures possible today...

Above normal temperatures through the upcoming weekend...

Short term (today - Friday)
Deep upper level troughing over the western u.S. Will
maintain strong upper level ridging over the western
atlantic and florida today. The upper ridge will weaken some
and begin to retrograde west southwest toward west central
florida on Friday. Similar to the last several days large
scale subsidence and limited moisture should continue to
inhibit rain chances across the region today with just a
slight chance of a few showers on Friday as the overall
suppression from the upper ridge weakens some, otherwise dry
and very warm conditions will continue. Some patchy fog
will be possible across the nature coast counties the next
few days, mainly during the late night and early morning
hours.

Temperatures will continue to run well above normal for this
time of the year and some record high temperatures will
again be possible today. See the climate section below for
record high information for today and Friday. High
temperatures today and again on Friday will climb into the
lower 80s along the coast, and mid to upper 80s inland with
lows tonight in the lower 60s across the nature coast, and
mid to upper 60s central and south.

Mid term long term (Friday night - Wednesday)
A trough low aloft the 4-corners region ejects out over the
plains and tracks across the great lakes late in the
weekend then moves through eastern canada during early next
week. An upper ridge centered north of the bahamas slips
west-southwest across fl and settles over the southwestern
gulf of mexico for the end of the period. At the surface
high pressure meanders in the open atlantic near bermuda and
weakens with time. An axis initially extending from this
high through the gulf coastal states pivots down across fl
and through the gulf of mexico by late Sun - in response to
the upper trough low pushing a frontal boundary across the
central then eastern u.S. The boundary stalls along the gulf
coast and across north fl Mon then slowly dissipates there
through mid-week.

The upper ridging will maintain a warm and somewhat stable
airmass. However... The surface ridge axis dropping across
the area will shift the low level flow from southeasterly to
southerly then southwesterly into the first of next
week... Increasing moisture in the lower levels. This will be
enough... Along with sea breeze boundaries and the
approaching frontal boundary... To over ride the stability
and result in isolated to scattered showers mainly in the
afternoons. Temperatures continue to run well above normal
but will decrease a bit through the period... Due to the
showers and a few more clouds.

Aviation
Some brief MVFR vsbys from patchy fog may impact klal and
kpgd terminals between 09-13z this morning, otherwiseVFR
will prevail at all terminal sites during the next 24 hours.

East-southeast winds in the 6 to 9 knot range this morning
will increase to 9 to 12 knots after 15z. East-southeast
winds will diminish to around 5 knots after 02z tonight.

Marine
Strong surface high pressure from the western atlantic
extending west across the southeastern states and northern
gulf coast will maintain southeast winds across the gulf
waters through Friday. The pressure gradient associated with
the high will continue to remain tight enough to keep any
sea breeze component just offshore today, but as the high
weakens some on Friday better chances for the sea breeze
component will increase. Now during the weekend and into
early next week a lighter southeast to southwest wind flow
is expected across the waters as the surface high weakens
further and sinks south to lie east to west across the
central peninsula during the latter part of the weekend with
an onshore sea breeze component developing along the coast
each afternoon. Winds and seas should remain below 15
knots 5 feet through the period with no headlines expected.

Fire weather
Sufficient low level moisture will keep humidity values
above critical levels through the end of the week and into
the upcoming weekend with no red flag conditions expected.

Some patchy fog will continue to be possible during the late
night and early morning hours the next several days, with
the best chances across the fog prone locations of the
nature coast, but widespread visibility restrictions are not
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.
