.SHORT TERM...
(Today through Friday)
Issued at 300 AM EDT Thu Oct 1 2026

Another batch of low clouds and fog will be possible right around
sunrise this morning with improvements expected between 10-11am.
Continued dry weather and warming temperatures are expected for
North and Central Georgia today as midlevel ridging remains parked
over the Southeast. Afternoon temperatures will rise into the 80s to
low 90s everywhere outside of the North GA mountains. Our weather
pattern begins to shift heading into Friday as the mid-level ridge
slides towards the East Coast. Another morning of foggy conditions
is likely on Friday as increasingly southerly flow pulls in
moisture. By the afternoon, isolated to scattered showers and
thunderstorms will be possible ahead of an approaching frontal
boundary. Though better opportunities for wetting rainfall will
arrive for many by the weekend. Continue to enjoy the dry weather
while you can as a more active unsettled weather pattern returns to
North and Central GA at the start of the long-term period discussed
below.

.LONG TERM...
(Friday night through Wednesday)
Issued at 300 AM EDT Thu Oct 1 2026

By Fri night tropical moisture will have moved inland across the
region from the Gulf, with a frontal boundary extending from the Mid-
Atlantic states to SW TX.  Southerly flow across the area will
continue to bring deep layered moisture into the state through the
weekend as the frontal boundary pushes slowly southward. By Sat
morning the frontal boundary will have stalled just north of the
state and is forecast to stay there through Sun evening. This frontal
boundary will act as a block not allowing the tropical moisture to
move out of the region while moisture continues to flow from the
Gulf in the southerly flow. This will put GA in a prime location to
see multiple inches of precipitation Fri through Mon.

The models have changed a bit with the location of the highest
amounts of precip as they are now showing higher amounts across
South GA vs North GA. This go round seeing 2 to 4 inch totals across
central GA with 1 to 3 inch totals across North GA. Due to the
limited amount of precipitation we have seen overt the past few
weeks, central GA can handle a bit more rain than north GA but 2 to
4 inches is still a lot of water in just 3 to 4 days. Will still
need to keep a close eye on the flooding potential across the area.
Still not seeing much in the way of instability across the area but
we could still see some thunderstorms Fri and Sat.

By daybreak Monday the the frontal boundary will be moving south
ushering in a much drier and cooler airmass into North GA. This
boundary does stall again across south GA/north FL so precip chances
will be relegated to central Georgia through day 7. Temps will be
very warm Fri with things beginning to cool as the precip moves in
Sat. High temp Fri expected in the 80s to lower 90s with highs Sat
mainly in the 80s. High temps only expected to get up into the 70s
Sun through Wed.
