.KEY MESSAGES...

  -  Scattered thunderstorms will be possible each day this
     week posing a threat for gusty winds and locally heavy
     rainfall.

  - Impactful heat is becoming increasingly likely as heat indices
    return to the mid 90s to low 100s by the middle of the week.

.SHORT TERM...
(Today through Tuesday)
Issued at 313 AM EDT Mon Aug 10 2026

Mostly clear skies across the area with the exception of north
Georgia which will likely see low clouds and patchy fog filter
in just before sunrise. While the pattern as a whole hasn`t
changed too much, the influence of the mid level ridging pushes
further west into the the gulf and southern Georgia which may
limit storm potential over central Georgia today to more of an
isolated chance. On the other hand, a boundary between this
feature and the largely zonal flow over southern TN and northward
will enhance thunderstorm potential over northern Georgia.
Currently expecting similar coverage as yesterday. With PWATs in
the 1.8-2" range and CAPE values forecasted to be in the 1500-2000
J/kg range the main threats will continue to be gusty winds and
locally heavy rainfall. Tuesday will be much of the same pattern
although central Georgia could see a bit more coverage.

Temperature today will warm into the low to mid 90s with heat
index values in the low 100s. Far southeast central Georgia may
have a couple of hours closer to 105 but should stay just below
criteria. Tuesday, temps stay similar but heat index values reach
at or above 105 for portions of southeast central Georgia with a
heat advisory possible

.LONG TERM...
(Tuesday night through Sunday)
Issued at 313 AM EDT Mon Aug 10 2026

Over the course of the long term period, ridging initially situated
atop the Desert Southwest will translate eastward, stagnating over
the Southeast for several days. In the absence of stronger
kinematics, any disturbances traversing mid-upper flow may help to
locally bolster convective coverage (or perhaps intensity) but by
and large, scattered to numerous garden variety summertime
thunderstorms are expected each afternoon through the extended
range. Moisture streaming off of the Gulf will support dewpoints in
the mid-to-upper 70s, sufficient to support progressively more
oppressive heat from midweek on. Highs on Wednesday are progged to
remain largely seasonable, in the upper 80s to mid 90s (within a
couple degrees of norms). However, air temperatures will return to
the 90s areawide by the weekend. As such, heat index values will
surge into the triple digits. Heat Advisory criteria is likely to be
met for at least subsets of the eastern portion of the area, and
conditions will need to be monitored for potential Extreme Heat
products assuming trends continue. Either way, make next weekend`s
plans with a high likelihood of impactful heat in mind.

.AVIATION...
(12Z TAFS)
Issued at 628 AM EDT Mon Aug 10 2026

Mostly clear skies will continue through ~15-16z when a cu field
forms ~3-4kft. Chance for TSRA from 20-24z today but could see
TSRA as early as 19z. Winds pick up out of the W ~15z and remain
at 5-7kt through the evening before becoming VRB overnight.


//ATL Confidence...12Z Update...
Medium to high confidence on all elements.
