Near term [through tonight]
A deepening surface low sliding east through the gulf will interact
with a boundary pushing SE through the big bend. This will work to
amp up rainfall and maybe a few thunderstorms over the gulf before
dragging them ashore overnight. Rainfall will then continue
throughout the period, becoming moderate at times. Some shower
activity will likely slide north into the florida panhandle and se
georgia, however the majority is expected to stay south and east of
jefferson county.

Short term [Thursday through Friday night]
In the upper levels a deep trough will be over the eastern u.S. At
the surface a gulf low in northeastern gulf of mexico will continue
to drift northeastward moving through northern florida on Friday.

High pressure will be over the lower mississippi valley and the
tennessee valley. With cold dry air to the north and west, rain will
stay fairly confined to big bend florida and south central georgia.

Rain chances will be lower in southeast alabama, panhandle florida
and parts of southwest georgia. Eastern big bend florida will likely
get the most rain with 1 to 2 inches forecast. Pops range from 5 (in
the west) to 85 (in the east) percent on Thursday. Pops remain
elevated on Thursday night up to 65 percent. On Friday the low will
be over the peninsula and pops will decrease slowly throughout the
day. Mostly cloudy skies will begin to clear out on Friday and
Friday night. Highs will be in the 60s. Lows will be mainly in the
40s.

Long term [Saturday through Wednesday]
In the upper levels a deep trough will be over the eastern
u.S. Until a ridge builds in on Monday night. At the surface a weak
decaying cold front will move through on Sunday followed by high
pressure in the southeast. Pops will be near zero this forecast
period even as the weak front moves through. The front will bring
cooler weather. Highs will be in the upper 60s and lower 70s. Lows
will be mainly in the 40s.

Aviation [through 18z Thursday]
Generally MVFR conditions expected to prevail into this evening.

-ra shra will then be pushing in from the gulf generally east and
south of a line drawn from ktlh to kvld. -ra shra may still be
possible west of that line. Expect CIGS to deteriorate after 00z
becoming lifr at times, especially near ktlh and kvld.

Marine
Northeasterly winds will increase to 15 to 20 knots tonight.

Northeasterly winds around 20 knots are expected tomorrow and a
small craft advisory may be issued later on. Winds will decrease
Friday afternoon and remain light to moderate through mid week.

Fire weather
Red flag conditions are not expected for the next several days.

A storm system will bring increasing rain chances to the region
starting tonight and continuing into Friday morning. Drier
weather will arrive Friday afternoon and continue into early
next week.

Hydrology
A gulf low will bring rain to the region tonight through Friday.

Highest rain totals will be in the eastern big bend florida as the
low tracks through central or northern florida. Expected rain totals
of 1 to 2 inches are predicted for eastern big bend florida.

Elsewhere rainfall totals of less than one inch are forecast with
most rain falling near the coast, big bend florida and south central
georgia. River flooding is not expected since river levels are still
low. Flash flooding is not expected but cannot be ruled out at this
time.

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.
