Near term through Tuesday ...

near stationary frontal boundary will slowly sink south across
region through Tuesday as high pressure builds to the northwest. The
airmass will remain moist across the region through Tuesday. The
combination of the moist airmass, diurnal instability and convergence
along boundary will result in numerous and showers and storms
this afternoon into the evening, then again Tuesday afternoon.

Shower activity could linger through the night across NE fl due to
the frontal boundary. Daytime temperatures will be a little
cooler than normal this period due to the coverage of clouds and
precipitation.

Short term Tuesday night-Thursday ...

old frontal boundary will remain nearly stationary west-east
over the central fl area with a plume of moisture along
and just north of the boundary. Southeast georgia remains
relatively in a dry airmass. High pressure is centered over va
area which slowly moves eastward through wed-wed night resulting
in breezy onshore flow for the coastal areas. From Wed night
through Thursday the trend in the model guidance is for the front
and associated moisture to shift northward in response mean layer
ridge moving into the wern atlc and weak trough aloft to dissipate
along the SE u.S. Coast. Low level flow turns east to southeast
pumping deep moisture well into ga Thursday to Thursday night. Wed
should see scattered convection mainly over inland NE fl
associated with low level convergence and daytime heating... And
more isolated shallow convection elsewhere. Rain chances should
diminish through the evening but onshore flow may bring a low
chance of showers to the coastal areas mainly over NE fl through
overnight hours. Better chance of rain all areas Thursday as old
front drifts northward and sea breezes act on this enhanced
moisture. Best chances in the ~55-65 percent range over inland
areas from marion county northwest to valdosta and waycross ga. A
bit lower chances elsewhere. Chances may start first along the
coast as sea breeze forms... Then elevated chances of rain
translate inland mid to late aftn ahead of (west) of the east sea
breeze and toward the west coast sea breeze. Locally heavy
rainfall is the main concern both Wed and thu... Especially
northeast fl where highest moisture and low level forcing is
expected. High temps near 90 inland to around the 85-89 near the
coastal areas wed... And a bit lower all areas on Thu mid to upper
80s due to higher rain chances and clouds.

Long term Friday-Monday ...

deep layer moisture expected over the area Friday though Saturday
mean layer ridge will be parked over north and central fl. Pwats
look to be about 105-120 percent of normal. We expect at least
scattered showers and storms each day Fri and Sat though largely
delayed until least late morning or early aftn. Whatever is left
of weak front lifts north into southeast u.S. Fri through sat.

Southeast low level flow Fri should push the best chance of rain
inland... But more southerly flow expected Sat which will push the
axis of higher rain chances a little further eastward. Sun-
mon... Both GFS and ECMWF develop weak low level trough thermal
trough over ga and NRN ga which should maintain elevated rain
chances. Each day, model consensus gives rain chances around or
above 60 percent. MAX temps each day will be held in check by
clouds precip... Close to normal or just below normal in the upper
80s to lower 90s. Locally heavy rainfall, frequent lightning, and
strong gusty winds will be possible with the strongest storms each
day.

Aviation
Thunderstorms will increase in coverage across the area this
afternoon, with restrictions expected. The convection will dissipate
later this evening, then initiate once again toward noon on Tuesday.

Marine
A nearly stationary front will slowly move south across area waters
through Tuesday night, as high pressure builds to the northwest and
north. High pressure ridge will build to the northeast Wednesday,
then to the east over the weekend.

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.
