.SHORT TERM...
(Today through Monday)
Issued at 327 AM EDT Sun Aug 30 2026

A transition in the upper level flow pattern is ongoing as the
period begins, with a longwave trough continuing to lift
northeastward away from the region ahead of a broad ridge centered
over the southern Great Plains. This ridge will shift towards the
Southeast over the course of the day and on Monday. The influence of
the ridge will kick off a warming trend in high temperatures this
afternoon, which will continue into the week ahead. High
temperatures this afternoon will rise into the low 90s across all
but the far northeastern mountains. With dewpoints remaining in the
low to mid 70s, heat index values will climb into the upper 90s to
low 100s in central Georgia. The building ridge will also help
suppress diurnal convection, leading to more isolated storm coverage
this afternoon. PoPs will range from 15-25% in central Georgia
during the peak heating hours while PoPs in north Georgia is
forecast to be less than 15%.

Conditions will be largely similar on Monday, though high
temperatures will be warmer in comparison, rising into the mid 90s
across the majority of the forecast area. Heat indices on Monday
are forecast to peak between 100-104 degrees along and south of
the I-85 corridor and in the upper 90s to near 100 in areas to the
north.

.LONG TERM...
(Monday night through Saturday)
Issued at 327 AM EDT Sun Aug 30 2026

High pressure continues to build in over the course of the long
term, limiting the chances of afternoon thunderstorms while slowly
increasing afternoon high temps and with it heat indices. Temps will
return to the mid 90s by the middle of the week with widespread
triple digit heat index values along and south of I-85. A heat
advisory may be needed for the southern portions of the CWA as early
as Monday.

Overnight lows will also be on the rise with the return of the mid
70s to much of the area. This doesn`t do much in providing relief
from the daytime heat; especially for vulnerable populations. Look
after each other, and keep an eye on pets and kids. Stay hydrated if
you plan to spend time outside.

Thunderstorm chances during the afternoon will be down to less than
10% for much of the area through the week. As a result, the chances
of cooling off with an afternoon thunderstorm decrease with it.

.AVIATION...
(06Z TAFS)
Issued at 136 AM EDT Sun Aug 30 2026

Conditions are primarily VFR to start the morning. Broken IFR
ceilings will be possible between 10-14Z this morning. Scattered
LIFR will also be possible underneath at ATL during this time
window. Patchy MVFR visibility restrictions will also be possible
at MCN in the early morning hours. Ceilings are anticipated to
improve to MVFR by 14Z and VFR during the afternoon. Isolated TSRA
will be possible in central GA this afternoon. A PROB30 for TSRA
has been introduced from 20-00Z at MCN. Chances are too low (but
non-zero) to warrant mention at any other TAF sites. Winds today
will be E/SE at 4-8 kts.

//ATL Confidence...06Z Update...
Medium confidence on low ceiling progression this morning.
High confidence on all other elements.
