Synopsis
High pressure will be the dominant weather feature this week.

Near term until 6 am this morning
Mainly clear skies and tranquil conditions overnight. There are
still no enough strong signals for any significant fog,
especially with a little too much mixing in the boundary layer
and many places struggling to reach their cross-over temps.

Instead, patchy only stratus fog seem more favored far inland
closer to daybreak. Temps remain on track.

Short term 6 am this morning through Wednesday
Mid level ridge will weaken temporarily Monday into Tuesday as
shortwave energy moves over the southeast. At the surface, a weak
front is progged to approach the area. The front will linger in the
vicinity into Wednesday, although it will become more ill-defined
with time. Couldn't rule out a few showers and thunderstorms Monday
and Tuesday during peak heating in proximity to the front, however
model soundings indicate limited moisture, so coverage should remain
fairly isolated. Maintained rain chances of 20%. On Wednesday, mid
and upper level heights will rebuild over the area. Large scale
subsidence should generally act as a cap on convection.

Otherwise, the main story will be the continued warm temperatures.

Highs are forecast to generally range from the upper 80s to low 90s
away from the beaches. Some spots in interior georgia could peak in
the mid 90s. Lows at night will be several degrees above normal,
mainly in the upper 60s to low 70s.

Long term Wednesday night through Sunday
Dry weather should prevail mid to late week as sfc high pressure
extending from the western atlantic becomes centered over the
southeast under a building ridge of high pressure aloft. A warming
trend is anticipated through the week as the ridge aloft becomes
quite strong and centered over the southeast united states. Highs
should generally range in the low mid 90s away from the coast
Wednesday and Thursday with overnight lows in the upper 60s lower
70s. Temps should be even warmer during the weekend as the mid upper
lvl ridge makes a slight shift south, setting up a west-northwest
downslope flow across the region. This includes warmer conditions
along the beaches given the potential for a pinned seabreeze. In
general, afternoon highs should peak in the mid upper 90s away from
the coast and mid upper 80s along near the beaches. The combination
of heat and mixed out moisture could support heat index values
around 100 degrees away from the coast Friday afternoon and Saturday
afternoon. Overnight lows should also be mild, generally in the
low mid 70s each night.

Aviation 06z Monday through Friday
Vfr through 06z Tuesday. Isolated shra tsra may develop on the
sea breeze this afternoon, but this activity looks too spotty
for any TAF considerations.

Extended aviation outlook:VFR conditions are expected at both chs
and sav terminals through the middle of the week.

Marine
Overnight: high pressure over the region will bring good marine
conditions. Wind will be S at 15 kt or less. Seas will be 2-3
ft.

Monday through Friday: relatively benign marine conditions expected
this week as high pressure remains the dominant weather feature.

South southwest winds on Monday and Tuesday will briefly become more
southeast on Wednesday, then return to a south southwest direction
by late week. Speeds will average 10 to 15 knots, generally peaking
in the afternoon near the coast with the sea breeze circulation.

Seas will range from 1 to 3 feet.

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.
