short term tonight through Wednesday night ...

the cold front will slowly traverse the forecast area overnight
with best rain chances across north georgia, and a slight chance
across central georgia. Rain chances should end by early tomorrow
afternoon as drier air quickly infiltrates the forecast area
behind the front. The best instability this afternoon and evening
is well south of the front and behind the front across central
georgia tomorrow afternoon but by that time the drier air has
filtered into the area and rain chances have diminished, have
therefore left thunder out of this forecast package. Expect lower
clouds to fill back in across north georgia into portions of
central georgi overnight into the morning hours with gradual
improvement tomorrow afternoon. Guidance showing above normal
temperatures across much of the area tonight, with near highs and
lows for tomorrow afternoon and Thursday morning.

Atwell
long term Thursday through Tuesday ...

overall, extended forecast is on track, and have made minor
adjustments to temperatures, dew points and precip chances to
account for the latest model guidance. Otherwise, a cooler and
relatively dry period is expected, with Saturday's rain chances not
amounting to much in the way of accumulations. Will need to watch
for frost potential early next week with lows approaching freezing
in the higher elevations.

Previous long term discussion:
the start of the long term will be dry.

The next cold front will move across the area mainly on Saturday
with the first rain chances over far north georgia on Friday with
rain chances increasing quickly over far N ga Friday night.

Saturday looks to start out on the wet side but precip should be
diminishing and ending late or the first part of Saturday evening.

Instability is limited with just a slight chance of thunderstorms
over mainly central ga on Saturday. The GFS is wetter with this system
to start than the european with both models moving the front and
moisture through the area rather quickly.

Sunday and Monday look to be dry.

Temperatures are expected to start out within a few degrees of normal
and briefly warm about 6-12 degrees above normal just ahead of the cold
front Friday night then dropping to below normal over the weekend.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
