.SHORT TERM...
(This afternoon through Thursday)
Issued at 205 PM EDT Wed Sep 16 2026

An anomalously strong mid-level ridge centered over northern
Georgia will continue to support broad subsidence over the region
through the short term. At the surface, high pressure stationed
off the Northeast coast will continue to filter northeasterly
winds through the region, continuing the influence of a modified
wedging pattern. With easterly flow in place, expect breezy
condition to develop for the remainder of the afternoon across the
central Georgia, with wind speeds around 5-10 mph occasional
gusts to 20mph, primarily over the southern CWA. Low clouds
associated with this feature have slowly burned off through the
morning hours, giving way to a decent cumulus field this
afternoon.

Any hope for cooler fall temperatures will have to wait a while
longer, with highs climbing into the upper 80s to low 90s across
most of the area this afternoon. The warmest temperatures will be
concentrated in the far northwestern portions of our CWA. As far as
precipitation is concerned, expect subsidence and dry air aloft
areawide to limit our chances through the day. One benefit of the
`wedge` is that surface mixing with dry air aloft will lower
dewpoints into the low to mid-60s, preventing more oppressive heat
from being realized.

On Thursday, the ridge axis will retrograde slightly to the west
while the CAD wedge lingers across portions of north Georgia. This
will lead to little change into prevailing flow pattern and sensible
weather across north and central Georgia. Low temperatures will
range from the low to mid-60s over central Georgia and the
mountains, with upper 60s elsewhere. Highs will warm a degree or two
as winds become more variable through the day. Expect dry
conditions to continue, with only an isolated chance of a shower
or thunderstorm, mostly over the northeastern portions of our
area.

.LONG TERM...
(Friday morning through next Tuesday)
Issued at 205 PM EDT Wed Sep 16 2026

As we approach the end of the work week, we continue to hold on to
unseasonably warm temperatures across much of the CWA. Highs in the
low to mid 90s with apparent temperatures in the triple digits will
continue into the weekend.

Thunderstorm chances during the afternoon will be down to less than
20% for much of the area through the week. The ridge is finally
expected to break down Sunday into Monday as a front approaches.
Isolated thunderstorms will be possible on Sunday afternoon,
becoming more widespread on Monday but total rainfall is expected to
be less than an inch for much of the CWA through the forecast
period.

The front will bring afternoon thunderstorms back into the forecast
to start off next week. This will help to moderate temps down to the
upper 80s and low 90s, but still warm for this time of year.
