905 am est Wed nov 22 2017

Update First few vis satellite images this morning in
combination with the water vapor bands show the pattern that will
be evolving across the region as we head into thanksgiving day.

A weak quasi-stationary boundary remains draped across central
florida this morning, which helped to aide the fog and stratus
that stubbornly remains in place around the lake this morning.

Further west, digging upper level trough and jet are driving the
development of a low level disturbance along the boundary across
the central gulf.

Satellite derived pwats show a patch of drier air moving across
the region currently, which is expected to limit convective
development today. However once the remaining fog stratus burns
off in an hour or two, expect scattered daytime cumulus
development. Once the seabreezes get going this afternoon, the
added lift may generate a few showers, especially as we get into a
little more favorable upper level dynamics late in the day.

Temperatures will climb into the low-mid 80s, with somewhat humid
dewpoints in the upper 60s and low 70s.

Prev discussion issued 641 am est Wed nov 22 2017
aviation... Fog across the region this morn with MVFR vsybs along
east coast and occasional ifr over interior west coast. Fog burns
off after 14z, withVFR expected through rest of TAF cycle. Light vrb
winds this morn become ene 6-10kts along east coast and W at kapf
after 17z, then light vrb again after sunset. Occasional shra
possible after 20z, but mainly over interior so no mention in tafs
at this point.

Prev discussion... Issued 351 am est Wed nov 22 2017
discussion... Firmly within the warm sector, south florida should
see another slightly drier day though some showers and
thunderstorms cannot be ruled out later today. The amplifying mid-
level trough remains over the northern gulf of mexico with various
shortwave troughs rounding it. As the shortwaves move across the
region, upticks in shower and thunderstorm activity are possible.

Heading into thanksgiving day, the mid-level trough will push
closer with the surface features potentially developing into a
surface low somewhere over the northeastern gulf. The associated
front will likely push across the area on Friday as the system
pushes northeastward across the peninsula. The convection
associated with this system could produce gusty wind and heavy
rainfall. While the best dynamics appear to be north of the
region, the availability of wind shear Thursday into Friday will
need to be monitored as any convection that can tap into it could
potentially create a severe weather threat.

Conditions should begin to dry out on Saturday as the drier air
begins to move in behind the system. Some remnant elevated wrap
around moisture could allow for some light rain, so a mention
remains in the forecast for Saturday though it should be
relatively short-lived. With the passage of a reinforcing cold
front to close out the weekend, next week will start with drier
and colder air moving into the region. While this taste of the dry
season will provide some chilly mornings and maximum temperatures
that will struggle to reach 80 over much of the area, it will
have access to any significantly colder air which should keep
temperatures from dipping much below the 50s even in the northern
interior portions of the forecast area.

Marine... Conditions across the area waters should remain fairly
benign until the front passes later in the week, though some
showers and thunderstorms could produce locally higher winds and
seas. Behind the front this weekend, increasing wind and building
seas will likely create some hazardous marine conditions.

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.
