Near term today and tonight ... Scattered light rain will move
across the area this morning from the south as inverted surface
trough lingers over NE fl SE ga. Trough will lift to the northwest
this afternoon with rain ending by early afternoon. Increasing se
winds will result in warm temperatures today as highs reach the
70s area wide this afternoon. Upper trough and associated cold
front to the west will approach this evening and move into the
area tonight. Widespread rain with isolated thunderstorms will
overspread the area from west to east after 03z tonight. Right
rear quadrant of strong upper jet will provide strong dynamics
tonight with increasing lift and vertical wind shear. Instability
will be weak and confined to fl where a marginal risk of isolated
strong to severe storms will exist with the possibility of strong
gusty winds. Above normal temperatures will continue through
tonight.

Short term Thursday through Saturday ... Showers associated
with the front will quickly exit to the east early Thursday. High
pressure will build from the west in the afternoon, with the
gradient flow leading to gusty conditions. Temperatures will
likely be warmest around noon or before, with readings falling in
the afternoon due to cold advection. The high will continue to
build to the west northwest Thursday night into Friday. The
resultant northwest flow will bring cooler air across region, with
lows in most locations falling into the 30s Thursday night, then
only recovering into the mid to upper 50s Friday. High pressure
is expected to build overhead Friday night through Saturday.

Long term Saturday night through Tuesday ... A trough of low
pressure is expected to develop over south fl Saturday night into
Sunday, with moisture running north into region. This trough will
linger into Monday, with potential for waves to move northeast
along it through Monday night. While expect most of the rain to
remain south, could see a few periods of rain across mainly NE fl.

A cold front will approach from the west Tuesday, with current
timing keeping most of the precipitation to the west.

Temperatures are expected to be near to slightly below normal into
Monday, then a little above normal ahead of the front for
Tuesday.

Aviation Vfr conditions expected today. Ceilings will be
mostly in the 3500 to 6000 foot range. Winds will increase from
the southeast at 10 to 15 knots with gusts to around 20 knots by
afternoon. Conditions will lower to MVFR with increasing rain
chances after 03z tonight ahead of approaching cold front.

Marine Tight pressure gradient will remain over the waters the
next few days with advisory conditions. Gale force gusts will be
possible offshore tonight through Thursday morning as a strong
cold front moves across the waters early Thursday morning.

Widespread rain with isolated thunderstorms will move across the
waters between midnight and mid-morning Thursday. High pressure
will build in behind the front and be reinforced this weekend.

Rip currents: moderate risk today and low on Thursday as winds
become offshore.

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.
