918 pm edt Sat jul 22 2017

Update Skies are mostly cloudy across southern zones due to
debris clouds from earlier convection today while southeast ga is
mostly clear at this time. Nearly all convection has dissipated
with lingering light patches of rain over parts of northeast fl.

Temps are relatively cooling at this point in the evening where
rains fell from this aftn... With locally strong downbursts and
heavy rainfall over northeast fl reported.

Sfc high pressure is well south of the area and 500 mb analysis
shows low over marion county and a 300 mb low just east of the fl
east coast. Mid level troughing forecast over the region through
Sunday morning combined with high moisture (pwats 2 inches), llvl
moisture convergence from southwest flow, and vorticity advection
will lead to continued low chances of showers or a very isolated
tstms overnight... Mainly over inland NE fl... Though isolated
showers will still be possible over SE ga. Have trimmed pops
slightly rest of tonight and kept tstms chances a little lower
considering the airmass has been worked over. Have lower min temps
slightly as mins have already been met due to the cool rains.

Aviation Vfr conditions will prevail at all terminals with
showers and thunderstorms redeveloping over the northeast gulf
waters and pushing into the suwannee valley during the predawn
hours on Sunday. Sub-vfr conditions will be possible at gnv before
or towards 12z Sunday. The overall pattern suggests an early start
with morning showers with some isolated embedded thunderstorms
developing over the NE florida terminals between 12-15z. This
activity will lift northward toward kssi during the mid to late
morning. Storm motion will continue from the SW or W favoring the
east side of the peninsula for an increase in convection
rain storms during the mid morning to mid afternoon. With an early
start, it is anticipated there will come an early end of the
convection between 22-24z.

Marine Little change in the forecast tonight. South to
southwest winds near 10-15 kt with seas near 2-4 ft expected.

Slightly stronger winds sustained near 15 kt over the north zones
through about 06z tonight. Radar is clear over the waters at this
time... But a small chance of convection is forecast toward the
early morning hours.

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.
