Synopsis
The region will remain situated between high pressure and a
coastal trough into early next week. A cold front is expected
to move through the region by mid week, followed by high
pressure through mid to late week.

Near term until 6 am Sunday morning
As of 815 pm: kclx detected a few showers just east of amz374,
tracking slowly east. The latest hrrr indicates that showers
will gradually develop within an inverted trough, developing
near the ga coast around daybreak. I will maintain schc pops
along coastal counties, mainly from the mouth of the savannah
river south along the ga coast.

As of 510 pm: latest IR satellite indicated a large area of
cirrus clouds streaming east over the forecast area. I will
update the forecast to increase sky cover across the region this
evening and overnight. Otherwise, the forecast appears in good
shape.

Previous discussion:
clear and calm early this evening, then northeast winds will
increase slightly overnight as a coastal trough develops. Weak
isentropic ascent will allow stratocumulus to develop along the
ga coast and spread inland toward daybreak. A few light showers
may brush the ga coast around daybreak Sunday. Lows will be in
the 40s.

Short term 6 am Sunday morning through Tuesday
Sunday through Monday: pooling of lower tropospheric moisture
in the vicinity of a coastal trough will support isolated scattered
showers, especially east of i-95, Sunday into Monday morning.

Then, any showers should push offshore Monday afternoon as drier
air begins to spread into the area from the W nw. High temps
will average in the upper 60s north to lower 70s south both
days.

Sunday night: low temp dewpoint spreads and light winds could
support some fog, although cloud cover could limit fog potential.

Otherwise, low temps will range from the upper 40s inland to
mid upper 50s on the beaches.

Monday night and Tuesday: a weak, dry cold front will push through
the region, and building high pressure will continue to usher drier
air into the area. Dewpoints will decrease somewhat, but another
night of low temperatures in the mid upper 40s inland 50s at the
coast will give way to another day of highs in the mid upper 60s
north and lower 70s south Tuesday.

Long term Tuesday night through Saturday
A likely dry surface cold front looks to cross the forecast area
late Tuesday or very early Wednesday, followed by additional high
pressure which should persist into late next week. Model divergence
increases by the end of the week. Onshore flow and increasing
moisture levels will set the stage and a developing coastal trough
or possible surface low could provide the forcing for precipitation
production heading into the weekend.

Aviation 01z Sunday through Thursday
Vfr through 00z Sunday. Cirrus will likely stream east across
the area through late tonight, sourced out of the deep south.

Late tonight into the pre-dawn, stratus should increase from the
east, mainly over ksav. These clouds are expected to remainVFR.

Extended aviation outlook: brief periods of flight restrictions will
be possible Sunday night into Monday morning due to the potential
for showers and perhaps even low clouds fog. Otherwise,VFR.

Marine
Weak northeast winds will gradually increase overnight as a
coastal trough takes shape. Seas will also rise slightly during
the overnight.

Sunday through Thursday night: winds and seas are expected to
remain below small craft advisory levels through midweek. Then,
a tightening northeast pressure gradient could translate to sca
winds seas by Thursday.

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.
