.SHORT TERM...
(Today through Saturday)
Issued at 151 AM EDT Fri Sep 26 2025
A closed mid-level low and associated cold front over the TN
Valley will continue to be the primary driver of weather
conditions across north and central GA through Saturday. Ahead of
these features, that are slowly moving our way, deep mid-level
southwest flow continues to spread above normal moisture across
the area, with PWAT values of 1.5-2". This moisture combined with
large-scale ascent from the troughing will support scattered
showers and thunderstorms again today, with the highest coverage
during the afternoon to early evening hours across central GA.
While the cold front is expected to slowly push through the region
from later on today through early Saturday, the drier airmass
will not push in until we get on the backside of the mid-level low
late Saturday. So, we are expecting another round of isolated to
scattered showers and thunderstorms Saturday afternoon, primarily
across the eastern portions of the area. We could see a few strong
storms each day with gusty winds, frequent lightning, and heavy
rain, but no severe weather is anticipated. With the increased
cloud cover and passing cold front, temperatures will be closer to
normal than recent days, with highs in the low to mid 80s today
and Saturday.

.LONG TERM...
(Saturday night through Thursday)
Issued at 151 AM EDT Fri Sep 26 2025
The main story of the longterm continues to be the tropical
activity in the western Atlantic. TS Humberto has formed over the
western Atlantic and is expected to strengthen over the weekend.
With the strong high pressure over the Atlantic and the deep
positively tilted trough over a majority of the southern CONUS,
Humberto is expected to curve northeastward into the Atlantic
where it will stay away from the eastern seaboard. Now comes
Invest 94L which has an 80% chance of development over the next 48
hours and a 90% chance of development over the next 7 days. NHC
is highlighting that TD Imelda is likely to form late Friday into
the weekend and then potentially strengthen into a TS over the
weekend into early next week. This is when the uncertainty begins.
The models overall are in pretty good agreement in the short term
with Invest 94L pushing northward just west of Humberto. Then is
when the model spread begins. Imelda will be at the mercy of the
cutoff low expected to form over the southeastern CONUS and
Humberto to the east. The spread shows members pulling the system
around the cutoff low and into the US while other members show the
system being pulled out to sea along with Humberto. We are still
about a day away from seeing more certainty when it comes to this
forecast but much of north and central Georgia does look to be in
the area where impacts will be minimal (if any). Northeast/east
Georgia will be the place to watch more as certainty increases
over the next day or so for potential impacts. Regardless it
doesn`t hurt to review any plans you have and as always stay tuned
to the NHC forecast as well as ours.
Other than the tropical system activity temperatures looks to
moderate and give a nice taste of fall into the early week with
the cut off low pushing in colder air. Highs in the mid 70s to low
80s can be expected through the long term with lows approaching
the lower 60s to upper 50s. Wind gusts will also remain elevated
through much of the long term beginning this weekend into early
next week as the pressure gradient between the upper level cutoff
low and the tropical system set up over the area. Gusts currently
remain at 15- 20mph during the afternoons. &&

.AVIATION...
(18Z TAFS)
Issued at 203 PM EDT Fri Sep 26 2025
Improving conditions (MVFR-VFR) will make way for additional
shower and thunderstorm development this afternoon and evening.
Expect best coverage between now and 02z, then gradual diminishing
thereafter. At this time, have included PROB30 -TSRA for generally
20-02Z to handle storm coverage. Expect low level ceilings to
develop overnight, with IFR and LIFR the norm over much of the
area from 08-14Z. Areas of fog are possible after 08z.
Winds will remain light and mostly variable through today, nearly
calm overnight, and then NW Saturday at 7kt or less.
//ATL Confidence...18Z Update...
Medium confidence on all elements.
