Synopsis..Strong high pressure will build in and remain over the region through the end of the week and into the upcoming holiday weekend with mainly rain free conditions and hot temperatures. East southeast winds will prevail except becoming onshore along the coast during the afternoon. A subtle increase in the easterly flow is expected during Thursday and Friday which will keep the west coast sea breeze close to the coast. The increase in winds will also lead to and easterly surge which will support winds approaching cautionary levels during the evening and overnight hours, especially across the offshore waters. Lighter winds will return for the weekend as the high sinks south over the area.

Hot weather expected through the upcoming holiday
weekend...

Short term (tonight - Wednesday)
Weak surface high pressure will remain over the region
tonight as upper level ridging continues to build in over
the region from the west. Similar to yesterday a few showers
or storms will be possible along the inland moving sea
breeze the remainder of the afternoon with the best chances
across southwest florida. The showers storms will wind down
during the evening hours with mostly clear skies and mild
conditions expected overnight. On Wednesday high pressure
will remain in control with a light southeast wind flow
giving way to an onshore sea breeze component along the
coast during the afternoon. Drier air moving in from the
atlantic should support mainly dry and very warm conditions
under mostly sunny partly cloudy skies. Temps tonight and
Wednesday will remain above normal with lows tonight in the
upper 60s to lower 70s with daytime highs on Wednesday
climbing into the lower to mid 90s area-wide.

Long term (Wednesday night - Tuesday)
Persistent large scale upper level troughing over the
western u.S. Will maintain strong downstream upper level
ridging over the southeastern u.S. And florida through the
remainder of the week and into the upcoming memorial day
holiday weekend. A dry subsident air mass under the ridging
will support mainly rain-free conditions across the forecast
area along with hot and muggy conditions, with surface high
pressure from the atlantic extending southwest across the
northern peninsula supporting a light southeast wind flow
with an onshore sea breeze component developing along the
coast each afternoon. The easterly flow will increase a bit
during Thursday and Friday as the surface high to the north
gets reinforced with a easterly surge to near cautionary
levels possible during the evening and overnight hours,
especially over the offshore waters. Lighter winds will
return during the weekend as the ridge weakens a bit and
sinks south into the area. Temperatures will remain above
normal with overnight lows in the upper 60s to the lower
70s, with daytime highs climbing into the lower to mid 90s
along the coast, and mid to upper 90s inland, with some
inland areas possibly approaching 100 during the holiday
weekend. If you have outdoor plans for the upcoming holiday
weekend you should take appropriate steps in order to avoid
heat related illnesses. Drink plenty of water to stay
hydrated and stay in the shade if at all possible.

Aviation
Will maintain vcts at kpgd, kfmy, and krsw between 21-02z
to account for any shra tsra along the sea breeze, otherwise
vfr is expected during the next 24 hours. East- southeast
winds at 5 to 7 knots will prevail except becoming west
northwest at the coastal sites the remainder of the
afternoon. Light and variable winds can be expected after
02z tonight, then becoming southeast at 5 to 7 knots after
14z on Wednesday except becoming onshore again at the
coastal TAF sites during Wednesday afternoon with the sea
breeze.

Marine
High pressure from the atlantic extending west-southwest
across the northern florida peninsula will maintain a
light east-southeast wind flow over the gulf waters tonight
through Wednesday with an onshore sea breeze component
developing along the coast during the Wednesday afternoon.

During Thursday and Friday a reinforcing high from offshore
the mid atlantic coast extending southwest across the
northern peninsula will bring an uptick in the easterly flow
which will likely hold the west coast sea breeze close to
the coast and result in speeds approaching cautionary levels
with the surge (especially over the offshore waters) during
the late evening and overnight hours. Lighter winds will
return during the upcoming weekend and into early next week
as the high weakens and sinks south across the waters.

Fire weather
Hot and increasingly humid weather is expected across all of
west central and southwest florida through the remainder
of the week and into the upcoming holiday weekend as strong
high pressure builds in over the region. Humidity values are
expected to remain just above critical levels with no red
flag conditions expected. An increase in 20 foot winds and
transport winds combined with high mixing heights will
support high dispersion indices on Wednesday and Thursday,
otherwise no other fire weather hazards are expected at this
time.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
