.SHORT TERM...
(Today through Sunday)
Issued at 216 AM EDT Sat Sep 26 2026

A weekend of pleasant `fall-like` weather is on tap across North
and Central GA as a dry and mild airmass spreads over the area.
The drivers of this setup are a mid-level ridge over the South-
Central US and a powerful stacked low off coast of the Mid-
Atlantic. The northerly flow between these systems will bring in a
dry airmass featuring well below normal PWAT values (~0.5") and
dewpoints (mid to upper 40s by Sunday). As a result, skies will be
mostly clear outside of any patchy fog this morning. Temperatures
will feel a bit crisp in the mornings, falling to the low to mid
50s for most areas. It`s also worth mentioning that anyone getting
their fall festivities on in the North GA mountains may want to
pack an extra layer, as these areas could see morning lows in the
mid 40s! Afternoon high temps will rise to the upper 70s to low
80s each day across most of the area.

.LONG TERM...
(Sunday night through Friday)
Issued at 216 AM EDT Sat Sep 26 2026

By Monday, the mid-level ridge that supported a multi-day period
of potent northwesterly flow retrogrades westward, with shortwave
troughing beginning to sweep across the Southeast. Despite a turn
toward the slightly-less-benign aloft, high pressure remains in
place at the surface -- the resultant subsidence sufficient to
support continued near-negligible rain chances through midweek.
With a supremely dry airmass in place, portions of central Georgia
may approach critical relative humidity thresholds on Monday and
Tuesday.

Moisture will be on the upswing by Thursday, flow turning
southeasterly at the surface as a subtropical high nudges onshore.
After multiple days with PWATs lingering near climatological
minimums (between 0.4-0.7" -- at times well below the 10th
percentile), expect them to be dragged back above an inch. Chances
for isolated to scattered showers and thunderstorms will return
as the airmass moderates back toward summerlike, bringing an end
to our brief dry period for some.

While comparatively much drier air will linger (dewpoints in the
40s to 50s),temperatures will warm back into the upper 80s to
lower 90s next week -- some 5 to 12 degrees above average. Morning
lows will remain crisp through Wednesday, in the 40s for portions
of northeast Georgia at elevation, and in the 50s elsewhere. As
moisture rebounds midweek, lows will return to the 60s to near 70,
