Areas of dense morning fog today...

Near record warmth this weekend...

Near term Today and tonight...

persistent mean layer 1000-500 mb ridge axis offshore of the se
atlantic coast will shift ese through tonight which will
transition steering flow from sse to ssw with an increase in sw
tonight as the ridge axis settles across the southern fl
peninsula. An increase in moisture associated with an easterly
wave impacting the SE fl atlantic coast early this morning will
pivot northward across the peninsula through today, and will bring
an increased chance of showers this afternoon across our fl zones
roughly along and south of a live oak toward st. Augustine line
where low level convergence and diurnal instability will be
maximized between encroaching sea breezes. Resultant isolated to
scattered showers will drift back toward the atlantic coast after
sunset as SW steering flow increases, with a gradual decrease in
coverage expected through the night as diurnal instability is
lost, however, maintained a low 20% chance of showers for most of
ne fl through the pre-dawn hours Sunday. Refrained from inclusion
of tstorms today given persist mid level subsidence and dry air
with mean moisture between 700-500 mb per the gfs40 less than 25%
which will suppress deep convective growth.

Early morning fog will become dense at times both today and again
tonight. Dense fog advisories may be needed for portions of the
forecast area. Fog Sat night Sun morning favored across the suwannee
river valley and inland SE ga as low stratus layer advects inland
from the gulf of mexico.

Temperatures will continue to trend near record values, both for
daytime highs and also for overnight record high minimum
temperatures. Refer to climate section below for records.

Short term Sunday and Monday
Unseasonable warmth will continue with record MAX temps likely on
Sunday. Southwest flow will result in the warmest temperatures
occurring along the i-95 corridor both days. An atlantic
seabreeze may try to develop on Sunday but if it does it will be
pinned right at the coast. Beaches should still reach the lower
80s prior to the development of the seabreeze. No seabreeze on
Monday as southwest winds increase with breezy conditions expected
at inland locations. Monday should be the warmest day at the
beaches, with temps possibly reaching the mid 80s. We went above
guidance for MAX temps both days.

Gulf coast seabreeze will move well inland both days. Isolated
showers will be possible on Sunday as the seabreeze moves east
towards the atlantic coast. A cold front will stall northwest of
the area on Sunday and there is a low chance of showers at areas
west and north of a line from waycross to jesup.

The front will finally get pushed into southeast georgia late
Monday afternoon and then through northeast florida Monday night.

A pre-frontal line of scattered showers and possibly a few
thunderstorms will move into southeast georgia Monday afternoon.

This activity will weaken and diminish as the upper level energy
gets deflected north of the area. A few showers will be possible
across the suwannee valley region of northeast florida, but other
than that, most of northeast florida will remain dry as the front
moves through Monday night.

Long term Tuesday through Friday ...

although temperatures will cool some on Tuesday with northeast
winds in the wake of the front, temperatures will remain above
normal. The coolest readings however will be along the coast with
highs only around 70.

Winds quickly veer towards the south on Wednesday as a warm front
lifts north. Temperatures will warm back into the upper 70s to
lower 80s with the warmest readings across our southern zones.

Isolated light showers will be possible along the atlantic coast
in moist onshore flow along the seabreeze warm front. A better
chance for scattered showers will exist across inland southeast
georgia in conjunction with the warm front and weak upper level

Thursday will be windy and warm as southwest flow increases in
advance of the next cold front. This cold front is expected to
move quickly across the area in the Thursday afternoon evening
timeframe. There appears to be just enough moisture forcing to
support at least a few showers along the frontal boundary late
Thursday afternoon and evening. Noticeably cooler drier air will
filter into the area with breezy northwest winds on Friday.

Ifr conditions expected to impact the terminals this morning with
highest potential for lifr or lower at vqq and gnv. Fog will lift
into low cumulus field by 14z withVFR conditions expected today.

Potential for restrictions tonight, but confidence in ifr not as
high as previous nights given low clouds and low chances for
showers impacting NE fl terminals late this afternoon into
tonight. Included vcsh at gnv and sgj after 02z.

Prevailing winds sse 5-10 kts inner waters with 10-15 kts over
the outer waters today with combined seas 3-5 ft. Dropped the scec
headline for the outer waters given observed waves 3.6 ft greys
reef with potential again tonight for elevated scec seas as sse
winds increase. High pressure will shift sse of the region today
through Sunday night ahead of a weakening cold front. This front
will gradually shift south of the waters Monday into Monday night
as high pressure strengthens over the mid-atlantic region. Onshore
flow will return Tuesday, then winds veer quickly to the south
wed as a warm front lifts northward over the waters ahead of a
stronger frontal system which will impact the waters late in the
week with the potential for advisory conditions under wnw flow.

Rip currents: moderate risk this weekend.

Near record MAX temperatures and near record high minimum
temperatures expected today through Sunday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
