GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 1010 Am Est Tue Nov 21 2017
Synopsis..High pressure off the mid atlantic coast early this morning will move further to the east over the atlantic ocean today as an upper level disturbance over the gulf moves east across the florida peninsula. At the same time a stalled frontal boundary across the florida straits will lift back to the north as a warm front. Increasing moisture combined with the trough and warm front will support scattered to numerous showers and isolated Thunderstorms over the gulf waters today. On Wednesday an area of low pressure will develop over the gulf. This low will then move east northeast across the northern florida peninsula during Thursday and Thursday night and into the atlantic on Friday. Sufficient moisture combined with this storm system will continue to support scattered to numerous showers and isolated Thunderstorms over the waters through Friday. Pleasant dry weather will return to the waters on Saturday as high pressure builds in over the region.

Update
Mid upper level trough will continue to amplify over the western
gulf of mexico with a lead shortwave moving across the region
today. This combined with the warm front lifting north will lead
to scattered to numerous showers and possibly a few thunderstorms.

Area of showers ahead of the warm front over southwest and south
central florida early this morning will move north during the day
so the best chances will reach central florida around midday early
afternoon and then the nature coast this afternoon. Rain chances
will diminish behind the front, but with some Sun we could see a
few more showers and storms pop up. Temperatures will climb into
the mid 70s north to lower 80s southwest and southern interior.

Have adjusted the rain chance timing in the grids and will update
zone forecast shortly. Remainder of forecast look on track at this
time.

Aviation
Some MVFR local ifr conditions will be possible in convection
today, otherwise mainlyVFR ceilings are expected. Tonight
conditions will deteriorate with MVFR and eventually ifr local
lifr conditions in low clouds and fog anticipated.

Marine
Gradient will relax today as high pressure off the southeast u.S.

Coast continues to move further out into the atlantic ocean
allowing winds to diminish. East to southeast flow will shift to
onshore across the central and southern waters as the warm front
lifts north. Winds will remain rather light tonight through
Wednesday then begin to increase as low pressure develops over the
central gulf and moves east late in the week. Present marine
forecast looks ok with no major changes planned for late morning
forecast.

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.
