.SHORT TERM...
(This afternoon through Monday)
Issued at 226 PM EDT Sun Sep 27 2026

During the short term period today and Monday, Georgia will remain
positioned between an mid-level ridge extending from the southern
Great Plains toward the Great Lakes and a vertically-stacked low
pressure system lingering near the New England coast. This will the
area under northwesterly flow aloft, which will continue to usher in
dry continental air into Georgia, evidenced by dewpoints in the 40s
and precipitable water values around 0.5 inches. The dry airmass
and broad surface high pressure associated with the ridge will
continue to inhibit precipitation chances today and Monday. With
mostly clear skies and strong radiational cooling, low
temperatures each morning are forecast to range from the upper 40s
in far northeast Georgia to the mid 50s in south-central Georgia.
High temperatures will largely climb into the low to mid 80s,
which will be about 3-6 degrees above daily normals. Strong
diurnal mixing will also contribute to RH values potentially
dropping to as low as 25% for an hour or two during peak heating
each afternoon.

.LONG TERM...
(Tuesday morning through next Saturday)
Issued at 226 PM EDT Sun Sep 27 2026

Pleasant conditions will continue through the work week.
Temperatures in the upper 80s and lower 90s for much of the CWA as
the high pressure begins to break down and winds become more
southerly in the second half of the week.

As we approach the weekend, the ridge will begin to break down and
southerly flow will begin to pull moisture back into the CWA. This
will bring chances for thunderstorms back up to between 25-35%
during the afternoon on Friday with more widespread thunderstorms
likely through the weekend. Temperatures should remain moderated to
the upper 80s and lower 90s, though that still has them running 5-10
degrees above normal for this time of year.

We`ll need to keep an eye on Sunday, as the best dynamics move
through the area for stronger thunderstorms. The ECMWF builds in
plenty of instability and decent low level shear, though the GFS
tends to keep a majority of the bulk shear off to the north.

.AVIATION...
(00Z TAFS)
Issued at 719 PM EDT Sun Sep 27 2026

VFR conditions will persist through the TAF period with mostly
clear skies and only high clouds. Overnight winds will be near
calm to light and NNW trending to NNE by 12-14Z before back toward
NNW after 18Z at speeds 3-7 kts.


//ATL Confidence...00Z Update...
