Update
Scattered thunderstorms and rainshowers continue to move in from the
gulf coast waters this morning. Interaction between high pressure
ridging over southern florida and troughing over the east coast
is keeping a southwest wind flow over the region resulting in a
moisture rich environment. The 12z morning sounding showed a
reflection of this with 2.18 inches pwat and southwest winds
through 20k feet. Latest hrrr guidance keeps rain chances high
with 50-80% pops expected across the region today with the highest
chances north of tampa bay. Based on latest surface observations
and satellite imagery, the forecast looks good for now with no
major changes needed.

Aviation
We continue to remain in a very moist and unstable southwest flow
through the day. Shra with embedded tsra can be expected through the
forecast period with southwest winds around 5-10 knots. The highest
rain storm chances will be from ksrq northward with brief periods of
MVFR ifr conditions possible through this afternoon, so will hold
vcts through 00z and will closely monitor radar for needed tempo
changes through the day.

Marine

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.
