Update
Surface high pressure from the western atlantic extending west
near the fl ga borders this morning continues to support a deep
layered southeast wind flow across the entire forecast area. 12z
raob data shows a decrease in overall moisture through the column
with a pw of 1.61 inches which is down just over two tenths of an
inch from yesterday at this time, which is confirmed by latest
goes-16 total precipitable water satellite imagery. Even though
moisture has decrease some this morning, model guidance shows it
increasing again during the afternoon, so am still expecting to
see scattered coverage of showers and storms develop during the
afternoon. With the southeast flow running in the 10-15 knot range
the west coast sea breeze will be slow to move inland and will
likely get pinned just to the west of the i-75 corridor where the
best convective coverage should set up during the late afternoon
hours along the east west coast sea breeze merger. Temperatures
will run near normal with highs around 90 to the lower 90s.

Ongoing forecast is in good shape so a morning update will be
required at this time.

Aviation
Brief MVFR CIGS vsbys and gusty winds up to 25 knots may impact
the terminals between 19-01z as scattered shra tsra develop over
the region and have handled with vcts for now. Outside of the
convectionVFR is expected during the next 24 hours. Light east
to southeast winds around 5 knots will become southeast at 6 to 8
knots after 14z except becoming southwest to west at ktpa, kpie,
and ksrq terminals after 19z with the sea breeze. Light southeast
winds will return to all terminals after 01z tonight.

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

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.
