.SHORT TERM...
(Today through Sunday)
Issued at 229 AM EDT Sat Aug 30 2025

Key Messages:

    - Isolated to scattered showers and thunderstorms are possible
      primarily along and south of the I-20/I-85 intersection this
      morning and afternoon.

    - Highs in the 80s today and mid-70s to mid-80s tomorrow remain
      below average for late August.

Discussion:

Given a mild temperature forecast (highs in the mid-70s to lower 80s
both today and tomorrow), the primary concern over the holiday
weekend will be coverage and northward extent of showers and
thunderstorms. A swath of moisture traversing the southern edge of
the broader mid-level trough spanning much of ECONUS will continue
to work to erode our unseasonably dry airmass through tomorrow.
PWATs in north Georgia remained in the 0.8-1.3" range yesterday
(generally between the 10th and 25th percentiles for late August),
with a stout dry layer evident above 700mb on both the 12Z and 00Z
soundings. Conversely, low-level moisture has rebounded, with a more
saturated column between 850 and 700mb. Model guidance suggests
PWATs will return to 1" or greater areawide by mid-morning Sunday,
but the lingering dry layer may continue to prevent unencumbered
convective development for the northern half of the forecast area.
Best chances (40-70%) for showers and thunderstorms will be focused
further south, fueled by the interaction of the aforementioned
moisture streaming in across the southern half of the forecast area
with a stalled frontal boundary draped across the Florida
panhandle/northern Gulf. Perhaps a few isolated passing showers for
the Metro.

Moving into Sunday, surface high pressure noses across New England
and the Mid-Atlantic, allowing for wedging (and characteristic U-
shaped isobars) to develop across north and north central Georgia.
Additional continental air filtering in should tamp precipitation
chances down further (20% or less) within the wedge airmass.
Otherwise, northeast Georgia -- orographically influenced -- and our
far southern/southeastern counties may see isolated to scattered
showers and thunderstorms during the afternoon.

.LONG TERM...
(Sunday night through Friday)
Issued at 229 AM EDT Sat Aug 30 2025

Key Messages:

    - Below normal temperatures continue through next week.

    - Mainly Isolated rain chances across the area except for
      Wednesday as a system moves through the region.

Discussion:

The extended forecast begins with the frontal boundary over the FL
peninsula extending westward across the northern gulf and then up
into southern LA and eastern TX. There are a few waves moving east
along the frontal boundary out of the central and southern plains
but the best moisture and dynamics stay south of the area especially
with a wedge of high pressure building into NE GA beginning Sun
night. This wedge appears to become the dominate feature for north
and central GA keeping things stable through at least Wed/Thu of
next week. This pattern will also keep a decent amount of moisture
across the region keeping diurnally driven precip chances in the 20%
to 30% range across the CWA Mon and Tue. There is a short wave
developing over the northern plains Mon morning and it slowly moves
SE, pushing into NW GA Tue afternoon/evening. This wave settles in
over the state Wed bringing increased precip chances (40% to 50%
PoPs) but the wedge will still be in place so not expecting much in
the way of severe weather. This wave moves NE Thu morning as the
next frontal boundary moving SE out of the northern plains pushes
into NW GA Thu afternoon/evening. This frontal boundary is not
expected to have a lot of moisture associated with it, but it will
usher in a much drier and cooler airmass going into next weekend.

Temps will remain below seasonal norms with highs mainly in the
upper 70s to middle 80s. Night time low temps will drop down into
the upper 50s to middle 60s through day 7.

.AVIATION...
(12Z TAFS)
Issued at 524 AM EDT Sat Aug 30 2025

Primarily VFR conds to continue. Isolated MVFR (and perhaps IFR
for CSG/MCN) is possible through daybreak, potentially accompanied
by low-VFR to MVFR vsbys in BR/FG. Chances for -SHRA are too low
for TAF mention for metro TAF sites (though nonzero), but are
ongoing further south. -TSRA likely to remain relegated to
CSG/MCN between 16 and 00Z. Winds will be out of the E side at
5-8kts, but may go CALM/VRB at times until sunrise.


//ATL Confidence...06Z Update...
Medium confidence ceiling progression and northward extent of
-SHRA.
High confidence all other elements.
