.SHORT TERM...
(Today through Wednesday)
Issued at 330 AM EDT Tue Sep 1 2026

A high pressure regime over the Southeast will dominate the weather
pattern over the short term period. The axis of an upper level ridge
is centered to the east of the Mississippi River Valley, and will
progress slowly eastward today and Wednesday. The influence of the
ridge will continue to bring lower cloud coverage and increasing
1000-500 mb heights, and thus steadily warming daytime temperatures
to the area. After the morning begins in the low 70s, high
temperatures will rise into the mid 90s across all but the higher
elevations of far northeast Georgia. The heat will continue to build
on Wednesday, with both lows and highs increasing by a couple of
degrees areawide. Dewpoints will remain in the upper 60s to low 70s,
with highest values in east-central Georgia. Heat index values will
climb into the upper 90s to low 100s across the majority of the area
this afternoon, then in the low to mid 100s on Wednesday afternoon.
A few isolated locations may briefly approach Heat Advisory criteria
during the mid-afternoon on Wednesday afternoon. Subsidence of dry
air under the ridge will largely inhibit chances for showers and
thunderstorms through the period. A rogue shower or thunderstorm
cannot be ruled out, most likely in the far northeast mountains or
east-central Georgia, though PoPs will be 10% or less areawide today
and Wednesday.

.LONG TERM...
(Wednesday night through Monday)
Issued at 330 AM EDT Tue Sep 1 2026

Heat will continue to be the main story through most of the forecast
though a break from it may be in sight. Humid conditions are
expected to bring heat index values up towards advisory criteria by
the end of the work week.

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
2 0% for much of the area through the week. The ridge is finally
expected to break down Saturday into Sunday. Isolated thunderstorms
will be possible on Saturday afternoon, becoming scattered come
Sunday but total rainfall is expected to be less than a quarter of
an inch for much of the CWA.

.AVIATION...
(12Z TAFS)
Issued at 631 AM EDT Tue Sep 1 2026

VFR conditions are expected through the period, with sparse
patches of mist not anticipated to impact any TAF sites this
morning. A cu field between 050-060 is forecast to develop by 16Z
and persist through the afternoon. The influence of high pressure
will keep winds light through the period. Winds will be 3 kts or
less and variable to start the morning, becoming NE at 3-6 kts
after 16Z. Winds will become light and variable again after
sunset.

//ATL Confidence...12Z Update...
High confidence on all elements.
