Short term tonight through Monday night
This should be our last dry day as increase moisture pushes in from
the gulf tonight and Monday. Still seeing temps well above seasonal
norms today but with the clouds and rain moving in over night and
through Monday expecting high temps to be about 2 to 8 deg cooler
Monday than today. Going with slight to chance pops tonight and
nearing likely pops Monday afternoon especially across N and NW ga.

There is a fairly stationary developing frontal system extending
from the mid atlantic states down to central tx that is expected to
move just ever so slightly eastward through the short term. At the
same time a weak open wave moves NE out of the gulf bringing
increased deep layer moisture to north and central ga. There is
not a lot of instability with this wave or associated with the front
so only expecting showers with general thunderstorms.

Long term Tuesday through Sunday
No significant changes were made to the lont term. GFS and ecmwf
continue to differ somewhat on how much drying will take place
during the upcoming weekend... With the GFS trending toward drier.

Not seeing much difference in the upper air pattern though. Will
leave north ga dry on Sunday as in the previous forecast. Previous
discussion is included below.

long term Monday night through Saturday ...

should have somewhat of a lingering wedge across north ga going
into Tuesday while the parent high pushes eastward off the new
england coast. By afternoon this feature should be mostly eroded
and regime Tuesday through Thursday looks to be marked by an
enhanced deep layer moisture field draped across the NW majority
of the CWA with increased precip potential from a conditionally
unstable environment and any weak perturbations traversing the
rather elongated moisture field NW side of the south atlantic
ridge. Models still have some slight discrepancies on how much
energy could generate along the broad trough to the north to push
a front and associated moisture swath south on Friday into
Saturday (the GFS still a bit more progressive drier than the
euro).

Temps cooler through period due to aforementioned regime and
precip potential though still a few degrees above climo.

18z update...

vfr to MVFR ceilings expected through the period as precip moves
into our area late tonight through Monday afternoon. Introduce
vcsh into the tafs just before sunrise Monday morning with MVFR
ceilings at the same time. Ceilings eventually get back into the
vfr range but could see them going up and down as precip
activity increased Monday afternoon. Winds expected to stay out
of the SE at 10kt or less.

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.
