.SHORT TERM...
(Today through Monday)
Issued at 219 AM EDT Sun Sep 27 2026

North and Central GA will see another few days of `false Fall` as
a dry and seasonable airmass remains over the area through Monday.
The drivers of this setup are a mid-level ridge over the South-
Central US and a powerful stacked low over the Northeast US. The
northerly flow between these systems will reinforce a dry airmass
over Georgia featuring well below normal PWAT values (~0.5") and
dewpoints (mid to upper 40s). Under mostly clear skies and light
winds, overnight low temperatures will fall to the low to mid 50s
for most areas. With daytime heating and mixing, temperatures will
gradually climb to the low to mid 80s each afternoon and feature
a light northwest breeze.

.LONG TERM...
(Monday night through Saturday)
Issued at 219 AM EDT Sun Sep 27 2026

The main takeaways of the long-term period are a warm-up, plus
rain chances returning on Friday and Saturday.

Our current dry airmass will remain in place through Wednesday.
In fact, relative humidity may fall to a near-critical threshold
for hazardous fire weather conditions on Tuesday afternoon.
Wednesday and Thursday will bring an amplifying subtropical ridge
over the Southeast. Subsidence associated with this area of high
pressure and continued dry air will make for essentially zero PoPs
through Thursday. Meanwhile, high temperatures will return to the
upper 80s and lower 90s (outside of the mountains, where highs in
the 70s are forecasted). Low temperatures will return to the
mid-60s to upper 60s essentially area-wide.

Moisture is progged to increase on Friday and Saturday as the
subtropical high weakens/shifts eastward and low-/mid-level flow
off of the Gulf and Atlantic spreads inland. This setup will bring
the return of isolated to scattered showers and storms both days.
The synoptic pattern at the end of the period and AI NWP
Convective Hazard Forecasts from NCAR lack signals for severe
weather potential. Rain could moderate the temperatures across
parts of the area and keep highs in the lower 80s to mid-80s both
days.

.AVIATION...

FEW fair weather cu between 050-060 in the mid to late afternoon
