Aviation [through 06z Friday]
Vfr conditions with light winds through the period. Scattered to
isolated afternoon thunderstorms with brief periods of MVFR
conditions will be possible at tlh, vld, and aby.

Prev discussion [954 pm edt]
Near term [through tonight]
Deep layer ridging and a slight increase in dry air at mid-levels is
leading to decreased coverage of convection across our area today
(compared to the past few days). However, deep layer moisture is
still impressive with pwat values slightly above 2", and the sea
breeze will provide enough forcing for scattered showers and
thunderstorms this afternoon and early evening. With west-
northwesterly winds, the sea breeze will not likely advance too far
inland, resulting in highest coverage of showers and thunderstorms
being confined to the fl panhandle and big bend regions. Mlcape
around 2000 j kg in these areas will definitely be sufficient for
thunderstorms, but weak mid-level lapse rates and lack of shear will
preclude chances of strong severe thunderstorms. However, isolated
gusty winds due to downbursts in strongest cells cannot be ruled
out. After highs mainly in the lower 90s this afternoon, overnight
lows are expected to be in the mid-70s inland with upper 70s along
the coast.

Short term [Thursday through Friday night]
Thursday will feature deep layer ridging with some slightly drier
air filtering into the region west of the apalachicola and
chattahoochee rivers. Convection will be driven along the
seabreeze, and mainly along the big bend and areas east. On
Friday, synoptic support from a tutt moving through the florida
straits and a couple of shortwaves moving through the great lakes
and middle mississippi valley will increase rain chances across
the entire region. At the surface, a weak cold front will be
entering the southeast and storms that form along it may move into
the region from the west later in the day. The earlier part of
the day should be dominated by a slightly more active seabreeze
front. Highs each day will be in the low to middle 90s with heat
indices climbing to around 105.

Long term [Saturday through Wednesday]
Saturday through Monday, the aforementioned cold front will be
reinforced by the shortwave moving through the ohio valley and
into the northeast. The front will most likely not move through
the entire region, instead bisect the tri-state region from
northeast to southwest. While the lingering front will keep rain
chances elevated through the first part of the period, there will
likely be locations that don't get any rain that reside behind the
front. By Monday night, the front will lift north and fizzle and
near seasonal pops should be expected to finish the period. Highs
should be near normal, around 90 degrees.

Marine
Light winds and low seas will prevail for the next several days.

The best chance for rain will be between midnight and noon, but
generally less than the past several days.

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

Hydrology
Widespread flooding is not anticipated this period. However,
typical afternoon and evening showers and storms each day could
lead to minor flooding in urban and poor drainage areas underneath
heavier storms.

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.
