Short term today through Thursday
A cold front near the ms river is on track to enter ga late
afternoon or early this evening. Meanwhile... A wedge has set up
across much of the forecast area. For now... Only spotty light
rain showing up on radar. Expecting showers to increase during the
day but the main rainfall should be in the vicinity of the front
late this afternoon and tonight. By 12z Thursday... The frontal
boundary should be just east of us. The main issue for this forecast
is the possibility of flooding. The QPF is a bit higher this run of
the models... With storm totals of 1.50 to 1.75 north and west
and up to 2.00 northeast... Locally to 2.50 higher elevations.

Debated about issuing a flood watch now but confidence in the area
involved was marginal... And how widespread it would be. After
coordination with neighbors we decided to let the next shift take
another look. Also... Still looks like a chance for light rain snow
northwest on the backside of this front Thursday morning.

The east winds and clouds will keep temperatures down for a while
but the strong overrunning could work against this. So highs today
are tricky. Winds will gust most of the day ahead of the front but
at this point are borderline for an advisory. The exception is a few
areas in the higher elevations that could reach criteria... But the
area is small and have held off on an advisory.

Long term Thursday night through Tuesday
With the passage of the cold front Wednesday night, the long term
forecast period will begin with a strong high pressure system,
currently located in canada's northwest territory, slowly moving
into the area. The boundary will be marked by a dry 'cold front'
that is expected to begin moving through georgia on Friday
morning. While this front won't bring substantually colder
temperatures to the area compared to the days before, it will
bring a dry surface airmass to the area with dewpoints in the
teens expected Saturday morning. There will be an upper-level wave
also marking the arrival of this high pressure system that
originally looked to bring some light snow flurries to far north
georgia, but as time has gone the probabilities of light snow
have dried up.

Instead, this surface high pressure is now expected to settle in
over the southeast and fight off most of the winter weather
opportunities that previously had the possibility of affected the
forecast area through next weekend. Alas, all good things must
come to an end as long term guidance is in remarkably good
agreement as of this writing for a cold midwestern subtropical
cyclone to move into the northeast by Tuesday with a long draping
cold front that is expected to push through next Tuesday. There's
currently not a lot of push behind this front outside of another
surface high pressure looking to move in behind it. There has also
been a diminishing trend to the amount of moisture associated
with this system. But given the cold temperatures behind the
front, some guidance is indicating winter precipitation could
follow a line of storms moving through the area. There's still a
lot of questions that will need to be resolved as time moves
forward concerning timing, moisture, and temperature.

after 21z today when more widespread shra expected with a
frontal passage. This evening could have lowering of CIGS again

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.
