.SHORT TERM...
(This afternoon through Monday)
Issued at 149 PM EDT Sun Aug 24 2025

Key Messages:

 - Isolated to scattered thunderstorms this afternoon across
   north and central Georgia. Severe weather is not expected.

 - Cold front will approach Georgia late afternoon with the dry
   and cool airmass pushing into the area overnight into Monday.

The main story for today will be that it is our last day of humid
conditions and rain chances through at least the middle of the
upcoming week. A cold front dropping across the TN Valley will
start to push across the region late this afternoon through
tonight, with isolated to scattered showers and storms possible
along and ahead of the front. Severe weather is not anticipated,
but sufficient moisture (1.5-1.8" PWAT) and instability
(1000-1500 J/kg MLCAPE) could lead to a few strong storms with
frequent lightning, gusty winds, and heavy rain. Any shower and
storm activity will taper off before midnight.

As the cold front pushes through the state tonight into early
Monday morning, it will usher in a much drier and cooler airmass,
with dewpoints crashing from the upper 60s to the mid to upper 50s
and PWAT values falling below 1". This will lead a dry, mostly
sunny, and pleasant Monday, with afternoon temps only reaching the
low to mid 80s across north GA, and upper 80s across central GA.
Winds will feel a little breezy during the afternoon, with gusts
to around 15-20 mph out of the NW.

.LONG TERM...
(Tuesday morning through next Saturday)
Issued at 149 PM EDT Sun Aug 24 2025

Key Messages:

 - Cool and dry conditions to linger through late week.

 - Chances for isolated to scattered thunderstorms return as we
   approach the weekend.

Moving into the extended and the final week of August, northwest
flow (normally a fairly active pattern) will prevail at the mid-
levels thanks to the Southeast`s placement on the lee side of a
ridge across the western US. However, with surface high pressure
nosing its way atop the eastern half of the country and lingering
for several days, resultant subsidence should be enough to fizzle
out any passing disturbances in the near term. A front riding
along the southern fringes of the broader mid-level trough
encompassing much of ECONUS is currently accompanied by near-
negligible precipitation chances (<5%) on Tuesday, but will
introduce a reinforcing shot of dry air in its wake. Owing to the
aforementioned much drier airmass (dewpoints in just the upper 40s
(!) to lower- 60s) and highs as much as 8-10 degrees below
average (in the mid-70s to mid-80s), conditions will be incredibly
pleasant through midday Thursday. Mornings are likely to be crisp
as well, dropping into the lower 50s to mid 60s each morning.

By late Thursday, a shortwave digging across the Great Lakes
region -- embedded within the broader troughiness at the mid-
levels -- will have nudged our presiding surface high offshore. A
swath of moisture in tow, chances for isolated to scattered
thunderstorms return Thursday afternoon and may linger through
the weekend. GEFS/EPS guidance diverges fairly significantly
regarding how much convective coverage we`ll see, as the GEFS
builds clearing and drying surface high pressure back in
relatively quickly on Friday. For now, opting for a middle of the
road solution that maintains 15-30% chances moving into Saturday.

With a cold front approaching a few showers will linger this
evening. Once the front passes sometime around or after 02Z CIGS
should clear out to SKC through the rest of the night. NW winds
around 10kts could gust up to 20kts beginning around 16Z.
