 - Rain and thunderstorm chances start to return across Central GA
   on Wednesday, then across the entire area by late week.

.SHORT TERM...
(Today through Wednesday)
Issued at 304 AM EDT Tue Sep 8 2026

A mid-level ridge covering most of the southern US will expand
over North and Central GA today and create pleasant conditions.
Subsidence from the ridge combined with a drier than normal
airmass (PWAT values around 1-1.25") will lead to near zero rain
chances across the area. Temperatures will rise into the upper 80s
to low 90s across much of the area under partly cloudy skies and
breezy easterly winds.

On Wednesday, the expansive mid-level ridge will start to split,
with one part centering over the Southeast US. With the lingering
dry airmass, rain chances will remain near zero across North GA.
Across Central GA, some low-level moisture will start to push in
from the southeast, supporting isolated to scattered afternoon
showers and storms, primarily south and east of Macon.
Temperatures will start to warm back up from our early week
`cool-down`, with highs in the low to mid 90s under mostly sunny
skies.

.LONG TERM...
(Wednesday night through Monday)
Issued at 304 AM EDT Tue Sep 8 2026

The mid-level ridge will begin to break down at the beginning of
the long-term period on Thursday as a shortwave trough drops
southeastward. This will bring a surface cold front southward into
the Ohio Valley, serving to increase PoPs by late week as
moisture interacts with the weak frontal boundary. This front now
looks to become stationary farther to our north than previously
favored, likely across the region from the Ohio Valley to
Tennessee Valley Friday into the coming weekend. With deeper
moisture pooling in advance of the front, expect elevated
diurnally-enhanced rain chances through the weekend, and the
potential for locally heavy rainfall may arise.

Any cooler and drier conditions will remain locked well to our
north through the coming weekend. Highs will remain well above
normal in the 90s through the week for most outside of the
mountains. With dewpoints remaining near or above 70, heat index
values in the upper 90s to low 100s will, things will continue
feeling decidedly summery for at least another week.
