.UPDATE...
Issued at 936 PM EST Sat Dec 6 2025

As cloud cover diminished around sunset and winds have become
light at 5 mph or less, strong radiational cooling has allowed for
the development of fog in areas south of the I-85 corridor. These
conditions, combined with a strong nocturnal inversion, make it
likely that the areal extent of this fog will expand as far north
as the north Atlanta metro area and to the southwest extent of the
forecast area. Dense fog is also already being observed, and is
likely to persist through mid-morning on Sunday in any areas where
fog develops, warranting the issuance of a Dense Fog Advisory
until 10 AM on Sunday. More uncertainty remains in portions of
east- central Georgia on the potential for fog development, as
cloud cover on the north side of the retreating frontal boundary
may inhibit its formation. The Dense Fog Advisory does not extend
into the far southeast or far north portions of the forecast
area, where fog is anticipated to be more patchy. It should also
be noted that temperatures in portions of northwest Georgia are
cooling slightly faster than previously forecast, and will drop
to near or just below freezing, increasing the possibility in
patchy freezing fog development in these locations.

.SHORT TERM...
(This afternoon through Sunday)
Issued at 122 PM EST Sat Dec 6 2025

Current radar imagery shows showers moving more into central GA
and should be on their way out of the area by later this
afternoon. Moist conditions are expected to hold into the
overnight hours with limited dry air movement. Another shortwave
moves across the southeast tomorrow surging moisture out ahead in
north and central Georgia tonight into tomorrow morning. Near
surface light easterly flow, increasing moisture, and some CAA
will drive the potential for widespread fog for areas mostly along
and south of I20. Visibilities may drop to 1/4 mile or less in
some areas and a dense fog advisory may be necessary for central
and portions of north Georgia. More patchy fog is also possible in
northern GA and may be co-located with temperatures near
freezing. Surfaces will likely not be cold enough for any rime
icing though there is some potential on the protected slopes in
far north Georgia. Low clouds and will likely hold conditions
steady late into the morning tomorrow (10/11am). Showers return to
the area once again tomorrow evening. No thunderstorms area
expected at this time.
