...Afternoon Area Forecast Discussion...

.KEY MESSAGES...

 - Scattered to numerous showers and storms are expected each day
   through the weekend. A few strong to severe storms will be
   possible in east Georgia this afternoon, which may produce
   damaging wind gusts.

 - Locally heavy rainfall may lead to isolated instances of flash
   flooding across portions of central Georgia today.

 - Seasonable temperatures are largely expected through the
   weekend, warming again early next week.

.SHORT TERM...
(This afternoon through Saturday)
Issued at 243 PM EDT Fri Aug 28 2026

Lack of cloud cover over I-85 this morning resulted in a more
favorable environment for showers and thunderstorms this afternoon
and evening. Current cu field is stretching along I-85 along and
near the boundary with good vertical development. This has
resulted in scattered showers and thunderstorms across this area.
Most of these storms are outflow dominant so we are likely to see
gusty winds with the potential for an isolated severe storm or
two with downbursts as the main threat. Widespread cloud cover
over the southern half of the area has resulted in less coverage
but should still see isolated to scattered storms pick up into
the late afternoon/early evening. Expecting similar conditions
tomorrow as the trough stays over the area between the metro and
MCN.

With the increased coverage of showers and thunderstorms,
expecting there to be more fog/low cloud issues in the morning so
keep an eye out for patchy fog if you are driving in the morning.

.LONG TERM...
(Sunday morning through next Thursday)
Issued at 243 PM EDT Fri Aug 28 2026

The long-term pattern is pretty straightforward, with an upper-
level ridge building over the area through the extended period.
Forecast guidance and ML products showcase plentiful moisture
advection from the Gulf along the western periphery of the Bermuda
High, along with enough daily instability to support diurnally
driven thunderstorm chances each day through next week. The
combination of precipitable water values ranging from 1.5-1.9
inches and a lack of well established steering could lead to some
localized flash flooding with any more robust convective
developments. However, severe potential remains limited to the
daily heating influences, given little deep-layer wind shear or
propagating shortwaves to aid in the development of more enhanced
convection. That being said, there is enough daily instability to
support isolated strong to severe storms with gusty winds being
the primary threat. As the ridge builds over our area,
precipitation chances do look to decrease somewhat compared to
recent days.

High temperatures will gradually climb into the low to mid-90s
through the period. Combined with dewpoints in the low 70s,
conditions will push heat indices into the triple digits by the
second half of next week. At that point, we will need to monitor the
heat index as values approach the 105-degree mark for the possible
issuance of a Heat Advisory.

.AVIATION...
(18Z TAFS)
Issued at 150 PM EDT Fri Aug 28 2026

Lingering cloud cover over MCN and CSG has pushed back the timing
of TSRA to 20z while the lack of morning cloud cover over the
metro ATL sites has pushed the timing of TSRA to 18z. Cu field
along I-85 is healthy and producing isolated to scattered
shra/tsra. This trend should continue through ~00z tonight,
potentially lingering through 02-03z. NW winds over the northern
TAF sites with SE winds over the southern two sites. Winds turn E
for all TAF sites ~12z tomorrow. Low clouds are possible again
~10-14z tomorrow at ~600-800ft. Chance for TSRA again tomorrow
afternoon ~18-23z.

//ATL Confidence...18Z Update...
Low confidence on low CIGS.
Medium to high confidence on all other elements.
