Discussion
Weak high pressure ridging across the northern half of the
area with a weak tropical wave just offshore of the SE fl
coast today. Some drier air remains across the nature coast,
while moisture is quickly returning across the central and
southern zones. This will keep limited rain chances across
the northern zones for this afternoon, and allow for
scattered showers and thunderstorms to develop later across
the central and southern areas, with the highest chances
across the south. Generally easterly winds will be in place,
with a weak sea breeze turning winds to the north late this
afternoon near the coast. Highs expected in the lower to mid
90s with feels-like temperatures 100-105. Current forecast
is on track and have no update planned.

Aviation
Moisture returning across the area for this afternoon. Light
east winds will increase to generally 08-10kts and become
more northerly near the coast later in the afternoon. Rain
chances start around 16z south, 18-20z northern terminals.

Convection should diminish by 02z with winds returning to
the east and weakening below 06kts overnight.

Marine
Generally easterly flow will be in place through much of the
period, with afternoon sea breezes turning winds onshore
near the coast each day. Scattered showers and thunderstorms
will become numerous for the end of the week into the
weekend as the tropical wave stalls along the fl east coast.

Currently no highlights are expected through the period, but
will be monitoring conditions as there is a 30 percent
chance of development in the next 5 days. Current forecast
is on track and have little change for the update.

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.
