.SHORT TERM...
(This afternoon through Sunday)
Issued at 237 PM EDT Sat Sep 13 2025
Key Messages
- No hazardous weather is anticipated in Georgia this weekend.
- Expect dry weather and partly cloudy skies.
Current satellite loop shows some fair weather CU developing across
the Southeastern U.S as the large high pressure ridge continues to
build down the eastern seaboard. There is also a very weak frontal
boundary over the upper MS river valley moving SE This boundary is
expected to move into North GA just before sunrise and push south
through he area Sunday. There is not very much moisture associated
with this front so only expecting increased cloud cover Sunday into
Monday. This front does disrupt the continuity of the high pressure
ridge, but the ridge begins to build back down the east coast
and into the state Sun night/Mon.
Temperatures will remain steady with nearly identical diurnal trends
expected Today and Sunday. Afternoon highs will peak in the mid 80s
with morning lows in the lower to mid 60s.

.LONG TERM...
(Monday morning through next Friday)
Issued at 237 PM EDT Sat Sep 13 2025
Key Messages:
- Dry and warm pattern will continue through next week, with no
meaningful precipitation forecast over that time.
- Afternoon highs will steadily rise during the early parts of the
week, reaching into the upper 80s to low 90s by Thursday and Friday.
The highly amplified upper level pattern will continue to move
eastward as the long term period begins on Monday. As the ridge
extends from the Mississippi River Valley towards the central Great
Lakes, a longwave trough will extend southward along the Eastern
Seaboard. This longwave will break on Monday, with the northern
portion moving away to the east and the southern portion evolving
into a weak cutoff low near the southeast Georgia coast. This low is
expected to drift northeast towards the mid-Atlantic coast through
mid-week, though some uncertainty remains with the exact progression
of its movement. With precipitable water values between 1.0-1.2
inches through much of the week, the influence of the upper low will
be the main factor driving precipitation chances through the long
term period. At this time, the track of the low is anticipated to
move further northeast than previous model runs, with PoPs being
lowered accordingly. As a result, PoPs will be 10% or less across
the area from Monday through Thursday, with the highest of these
meager rain chances across the higher elevations of far north
Georgia. Slight chance PoPs between 10-20% are then forecast on
Friday towards the end of the period.
Subsidence of warm and dry air underneath the upper ridge will
otherwise be keeping a lid on precipitation chances through most of
the week. High temperatures on Monday are expected to be in the
upper 80s across the majority of the area, with the exception of
some low to mid 80s to the northeast of the Atlanta metro area.
These highs will steadily climb underneath the ridge, and highs will
largely be in the low 90s by Thursday and Friday, which will be
about 5-10 degrees above average for mid-September. Overnight lows
will be in the upper 50s to low 60s each morning. By Friday, the
ridge will finally dampen as a shortwave trough swings through the
Great Plains around the periphery of a closed low over central
Canada. As an associated surface low develops over the Midwest on
Friday, a cold front will begin to work its way towards the
Tennessee Valley which could lead to a further increase in rain
chances just beyond the period.
