Update
Latest rap surface analysis shows high pressure from the western
atlantic extending west across the northern peninsula and into the
eastern gulf this morning with an east-southeast wind flow across
the forecast area. Morning RAOB data shows increased moisture across
the area with a pw of 1.82 inches. This moisture combined with daytime
heating will support scattered to numerous shower and thunderstorm
development along the sea breeze circulations during the afternoon
with the east-southeast steering flow favoring the best coverage and
highest rain chances (pops 60%) setting up along and to the west of
the i-75 corridor during mid to late afternoon with the storms then
ending or shifting west into the adjacent gulf waters during the
evening hours. Similar to previous days locally heavy rainfall will
be possible with the storms, and with the ground remaining quite
saturated from recent rains localized flooding of low lying and
poor drainage areas will be possible along with some additional
rises on area rivers. In addition to the rain strong gusty winds
and frequent lightning strikes will accompany the storms. Current
forecast has a good handle on all of this so a morning update will
not be required at this time.

Aviation
Developing shra tsra along the sea breeze will bring brief MVFR
cigs, vsbys, and some gusty winds to the terminals between 18-01z
and have included tempo groups to cover this, otherwiseVFR is
expected. Light east winds this morning will become southeast at
6 to 8 knots after 14z except becoming onshore at ksrq, kpie, and
ktpa after 19z with the sea breeze. Light and variable winds will
return to the terminals after 01z tonight.

Marine
High pressure across the northern peninsula will maintain east
southeast winds around 10 knots with seas of 2 feet or less over
the gulf waters the remainder of today with an onshore sea breeze
component developing along the coast from sarasota north during
the afternoon. Wind and seas will be higher near thunderstorms
during the late afternoon and evening hours, otherwise no headlines
are expected. Ongoing forecast is on track with no changes expected
in the mid morning update around 10 am.

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.
