.KEY MESSAGES...

- Hot and dry conditions are expected for most on Sunday.

- Patchy dense fog is possible this morning in areas that
  received recent heavy rainfall in recent days.

- Surface high pressure will suppress meaningful rain chances
  through Friday (15% or less each afternoon).

.SHORT TERM...
(Today through Monday)
Issued at 318 AM EDT Sun Sep 13 2026

Patchy dense fog has developed across portions of northeast Georgia
this morning, and further development is possible, especially in
areas that received heavy rainfall yesterday. As mid-level ridging
moves in aloft on Sunday, meaningful precipitation chances will be
effaced by strengthening subsidence, reinforced by building high
pressure at the surface. Isolated thunderstorms are possible across
our far southern tier, in the vicinity of a lingering tendril of
increased moisture, but most will see a dry (if hot) end to the
weekend.

The start of the work week will see a backdoor cold front approach
north Georgia, with surface winds shifting solidly to the northeast
as it does so. An isolated shower or thunderstorm is possible across
the terrain of northeast Georgia, otherwise expecting minimal
sensible impacts from its arrival -- temperatures are actually
likely to climb a couple of degrees, topping out more solidly in the
90s areawide.

.LONG TERM...
(Monday night through Saturday)
Issued at 318 AM EDT Sun Sep 13 2026

The long term period will begin on Monday night with an upper ridge
extending from the Deep South into southeast Canada. A surface high
associated with this ridge will also be moving from the eastern
Great Lakes towards the Northeast. Though low level moisture from
the Gulf will linger across Georgia (with dewpoints in the upper 60s
to low 70s), subsidence of dry mid-level air under the ridge will
largely suppress convection on Tuesday afternoon, with only isolated
thunderstorms anticipated in portions of east-central Georgia.
Underneath mostly clear skies, high temperatures are forecast to
rise into the low 90s in all but the far northeastern mountains on
Tuesday afternoon. Late Tuesday into Wednesday, the surface high
will lead to the development of a CAD wedge along the lee side of
the Appalachian, which is expected to spread relatively cooler and
drier air into the eastern portions of Georgia. Low temperatures on
Wednesday and Thursday will start each morning in the 60s while high
temperatures in the afternoons will be largely in the upper 80s.
With the upper ridge lingering over the eastern CONUS, rain chances
will remain minimal across the forecast area on Wednesday and
Thursday. Chances for diurnally-driven showers and thunderstorms
will gradually increase starting on Friday and into next weekend as
the axis of the ridge begins to retrograde back to the west of the
area.
