Inland frost development expected early this morning...

Near term (today and tomorrow morning)
Clear skies, cold temperatures, and some inland frost formation
this morning. Some cloud formation is expected later this
afternoon as the area of high pressure begins to push off to the
west later today. High temperatures today are expected to be
in the high 60s and low 70s, with the overnight low temperatures
ranging from the low 40s in southern georgia to the low 50s at the
southern edge of the forecast area.

Short term Sunday through Tuesday ...

high pressure will be to the north through Sunday night.

Expect a continued moderation of the air mass across the region
Sunday with MAX temperatures mainly in the 70s with some upper
60s over the altamaha river basin. An inverted coastal trough
develops in the onshore flow pattern. This inverted trough will
produce cloud cover for eastern counties through Sunday
night, along with the potential for coastal showers. Nocturnal
temperatures this period will be warmest near the NE fl coast due to
onshore flow and cloud cover, while readings inland will
be as much as 10 to 12 degrees cooler.

The coastal trof will move further eastward offshore Monday as weak
cold front moves southeast across the region. Behind the front,
high pressure builds to the northwest Monday night into Tuesday.

A decreasing cloud trend is expected for Monday and Tuesday,
with temperatures near to slightly above seasonal averages.

Long term Tuesday night through Friday ...

strong ridge of high pressure aloft will build over the north
central CONUS Wednesday moving the eastern CONUS by Wednesday
and Thursday. Strong surface high pressure will build to the
north Tuesday night into Wednesday, leading to an enhanced
onshore flow. Models are hinting at a coastal trough developing
midweek, which could lead to additional cloud cover, and possibly
a few coastal showers by Thursday. The coastal trough will move
northward off the georgia coast perhaps as a closed surface low
Thursday night with wrap-around precipitation furnishing scattered
showers over the coastal counties becoming more isolated inland.

An area of low pressure will be moving across the northern gulf
and over the region at the end of the week. This will bring some
isolated to widely scattered showers with a couple thunderstorms
south of sr16 and over the florida offshore waters. Near to a
little above normal temperatures will during this period.

Aviation
Vfr conditions throughout the day with some low level cloud
development in the afternoon along with the winds shifting to out
of a more northeasterly direction.

Marine
High pressure will move into the region through tonight, then
then shift to the north over the weekend. A weak coastal trough
is expected to develop over area waters by Saturday night. This
trough will remain through early Monday then push well offshore.

Stronger high pressure will build to the north of the area Wednesday
as another cold front moves through the area resulting in
strengthening north to northeast winds and building seas by mid
week.

Rip currents: moderate risk for northeast florida
low risk for southeast georgia

It is not checked for accuracy either by anyone at L-36.com 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.
