Near term through Saturday
Surface cold front will move south of the region early this evening.

Secondary trough will slide south across region tonight. Significant
mid level moisture along this secondary boundary could result in a
few isolated showers over SE ga this afternoon. High pressure will
build from the northwest late tonight into Saturday. This will
provide clearing from north to south through the day Saturday.

Temperatures are expected to be below normal for Saturday.

Short term Sat night-Monday
Sat night... High pressure settles over the ga carolinas region
with mostly clear skies except for a few high clouds push in aloft
towards morning. Min temps in the upper 30s across inland SE ga
and in the 40s elsewhere and near 50 along NE fl coast.

Sunday... High pressure drift off the SE us coast and expect
steering flow to become W SW with temps warming well into the 70s
for NE fl and near 70 across SE ga. Cloud cover slowly increases
as more high clouds stream across the region from the gomex.

Sun night... Enough moisture in SW flow on the back side of high
pressure ridge pushes out of the north gomex and will trigger some
shower activity across inland SE ga. Otherwise skies becoming
mostly cloudy and will hold min temps above normal with lows
generally in the mid upper 50s. Some patchy fog possible across
inland NE fl towards morning but may be too much cloud cover for
anything significant and have left out of forecast for now.

Monday... Shortwave energy aloft will push out of northern gomex
and into SE us around the high pressure ridge across north fl and
this will continue the threat of showers across SE ga while NE fl
remains mostly dry. Skies generally mostly cloudy SE ga and partly
cloudy NE fl and temps continue to moderate with highs into the
upper 70s near 80 for NE fl and lower to middle 70s for SE ga.

Thunderstorm chances still too low (less than 10%) to include in
the forecast for SE ga at this time.

Long term Tuesday-Friday
Tuesday... Next weakening cold front will push through the SE us
and into SE ga NE fl while losing mid upper level support but
likely enough moisture and low level convergence for at least
scattered showers area-wide. Thunderstorm probs still too low and
far out in time to include in forecast yet. Temps still above
normal with highs in the 70s near 80 and lows in the upper
50s near 60.

Wed-fri... The usual model diffs in this period as front washes out
and high pressure builds north of the region. The zonal flow aloft
tries to show a few weak disturbances moving along the old frontal
boundary to keep the slight chance of showers possible each day,
but timing still too far out for any confidence. Overall temps
cool slightly following the front on Wednesday with highs closer
to 70 but will rebound with highs well into the 70s by the end of
the week. Lows cool slightly but some cloud cover will keep them
in the upper 40s 50s for most areas.

Aviation
PrevailingVFR conditions are expected this 18z TAF period. However,
a brief period of MVFR can not be ruled out along with a few
sprinkles this afternoon and evening.

Marine
A cold front will move south of area waters tonight, with high
pressure building from the northwest overnight. The high will build
to the north Saturday, then northeast Saturday night into Sunday.

The high will build to the east into the early part of next week.

Rip currents: low risk.

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.
