Short term tonight through Saturday night
Models in pretty good agreement through the long term. Weak surface
front will merge with the lee side trough and drift into
central south georgia. Drier air will spread across the CWA behind
the front ending the chance of precip across north georgia late this
afternoon evening. Weak high pressure will build into the tennessee
valley keeping the drier and more stable air across north georgia
Saturday while proximity to the front will keep low pops across
central georgia Saturday afternoon. With the drier air will come
slightly warmer daytime temps Saturday with most areas outside of
the mountains seeing low to mid 90s. Slightly lower dewpoints on
Saturday should keep heat index values at 100 or less across central
georgia.

Long term Sunday through Friday
No changes made to the extended forecast. The upper level trough
continues to swing northeastward Sunday morning, which allows
zonal flow aloft through the day Sunday with upper level ridging
and surface high pressure to set up just east and northeast of the
forecast area. Extended models in good agreement stalling
weakened surface boundary over southeast portions of forecast area
Sunday evening through Monday.

A relatively benign pattern will set up for the beginning of the
week. However there will be enough moisture across the area the
diurnally driven showers and thunderstorms cannot be ruled out
each afternoon and evening. As the aforementioned surface boundary
will act as a focus for afternoon convection, the bulk of any
showers and thunderstorms are expected to remain south of the
path of the solar eclipse. Will continue slight to low chance pops
through the week.

The upper ridging begins to break down on Tuesday and surface high
shifts off the georgia coast as the next system sets up. Extended
models begin to diverge as impulses move through the flow north of
the forecast area. Weakening front again moves through portions of
georgia Wednesday into Thursday.

Guidance temperatures showing near normal through the period and
will continue to take a blend. Temperatures during the
eclipse (Monday) look to stay steady an hour before the maximum
obscurity (between 1pm-2pm), then drop a couple degrees up to 30
minutes after MAX obscurity (3pm). Temperatures are expected to
rebound quickly after the eclipse. The temperature drop will be
less for those under cloud cover precipitation. This drop in
temperature is not expected to impact the high temperature Monday
afternoon.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
