Short term tonight through Thursday night
High pressure over the area is weakening as frontal system moves in
across the region. Looks like the front has moves into western al
and making its way east. It should push into NW ga by 21-23z this
evening and continue moving east through tonight. Expecting showers
to increase from west to east over the next few hours and continue
across the state over night. By 12z Thursday... The frontal boundary
should be just east of our CWA with only a few lingering showers
remaining over eastern ga. With this rain moving through tonight
there will be an increased chance of flooding mainly across N ga
where the larger amounts are expected. Could see 1 to 3 inches of
accumulations for areas north of a rome to canton to cleveland line.

Have issued a flood watch for those areas through 12z Thu morning.

Gusty winds are also an issue with this system and have been seeing
winds gusting into the 30-35kt rage across the area. These wind
speeds are expected to stay elevated through tonight. With the
increased rain on top of the already saturated soils... Could see a
tree or two fall tonight. We have a wind advisory going and are
extending it to include more of central ga and taking it through 06z
thu.

Once this system exits the area tomorrow morning will see clearing
skies and cooler temps as a cooler airmass moves in. High temps thu
will stay mainly in the 40s and 50s with lows Thu night in the 20s
and 30s.

Long term Friday through Wednesday
High pressure and fair weather will be the rule for much of the long
term forecast period. However, a sharp cold front and colder
temperatures are expected by the end of the week. This system will
bring some potential for wintry weather across a good portion of the
cwfa.

Dry conditions and near to slightly below normal temperatures are
expected through the first half of the weekend. Both the ECMWF and
gfs are progging a shortwave and weak frontal boundary to impact far
northern ga by late Sunday into early Monday. Neither model is
producing much precip with this system, but the ECMWF is slightly
wetter and further south with the shortwave energy.

The next system is expected to impact the cwfa Tuesday in the form
of a sharp cold front. Much colder air is anticipated on the back
side of this boundary, and there is some potential for wintry
weather before all of the low level moisture clears out. Kept the p-
type as ra sn as it it way to early to nail down specifics. For now,
the chances for precip remain low, but will have to continue
monitoring.

Aviation 18z update... Precip moving into the area as
frontal system moves eastward out of the ms river valley. Will
begin to see shra at the TAF sites around 21-23z and continue
through 10-12z thu. The ceilings are mainly in theVFR to MVFR
range right now but they will fall as precip moves in. Expecting
mainly MVFR readings overnight but may see some brief periods of
ifr. Ceilings will lift back into theVFR range right around
sunrise Thu as the system exits the area. Winds are out of the se
in the 10-15kt range with gust to 30kt. Will continue to see these
elevated wind speeds through the TAF period even as winds turn
from the SE to the SW and then NW by the end of the TAF period.

Vsbys will be mainlyVFR except in and around shra activity where
we could see some MVFR vsbys.

Atl confidence... 18z update...

confidence medium to high on all elements.

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.
