Widespread rainfall event Thursday and Friday...

Near term through Thursday
An area of low pressure will develop and move northeast across the
gulf toward the region tonight. A wave will move northeast from this
low across the forecast area Thursday, with rainfall overspreading
the region, along with the potential for storms with periods of
heavy rain.

With the cloud cover temperatures will be above normal tonight, with
rain and clouds keeping readings below normal on Thursday.

Short term Thu night-Saturday
Thu night-Friday... Digging mid-level trof and shortwave energy
over the eastern gomex will keep deep moisture and lift across the
region and will continue the widespread rainfall event with
locally heavy rainfall. Still expect total rainfall amounts of 2-3
inches across NE fl for the event with locally higher amounts
possible with possible embedded isolated storms. Further nw
across SE ga lesser amounts expected. Surface low pressure trof
will remain south of the region and expect breezy NE sfc winds
along the atlc coast at 15-20g30 mph with lesser winds inland.

Cloudy skies through the period with lows generally in the 50s and
highs in the 60s.

Fri night-Saturday... Low pressure at the surface kicks NE and into
the atlc ocean as mid-level trof pushes eastward and rainfall ends
Friday evening from west to east with clearing skies and mostly
sunny conditions by Saturday afternoon. Lows in the 40s 50s fri
night and highs near 70 on Saturday as cooler and drier winds
become NW at 10-15g20 mph.

Long term Sunday-Wednesday
High pressure builds north of the region for most of the period
with mainly dry conditions. Surface flow becomes onshore NE for
most of the period but much of the isolated shower activity over
the coastal waters will remain there with just low chances of
brushing the coast at times. Temps will be generally close to
climo values with highs in the 65-75 range and lows in the 40s 50s
through the period.

Aviation
Stratus is expected this afternoon, which will cause restrictions at
kssi. Stratus will become more widespread and lower in height
tonight, with restrictions expected. Rain will also overspread the
region from the southwest overnight through Thursday. There is a
chance for mainly afternoon thunderstorms Thursday as well.

Marine
High pressure ridge will be over area waters this afternoon and
evening. An area of low pressure will develop over the eastern gulf
tonight into Thursday. This low will then slowly move east across
the region Thursday night through Friday night. High pressure will
build to the west on Saturday, then to the northwest Saturday night
into Sunday.

Rip currents: continued moderate risk through Thursday.

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.
