.SHORT TERM...
(This afternoon through Wednesday)
Issued at 248 PM EDT Tue Sep 17 2024

Current satellite loop shows the coastal low that move onshore the
Carolina coast yesterday is now centered and spinning near the
GA/SC/NC boarders. The models show this low center staying fairly
stationary for the next 24 hours before moving NE into the Mid
Atlantic states Wed night/Thu morning. The low center is weakening
and all were expecting is just increased cloud cover for most of
North and Central GA through the short term. There may be a few
locations across eastern portions of the state that see a showers or
two through Wed night but not expecting much in the way of thunder or
any heavy downpours from this system. These increased clouds will
help to keep high temperatures a bit cooler across north Georgia
compared to their central or south GA counterparts. Temperatures
north of I-20 will be mainly stay in the 70s to lower 80s Wed with
lows in the 50s to lower 60s. Areas south of I-20 will reach the mid
to upper 80s Wed.

.LONG TERM...
(Thursday morning through next Monday)
Issued at 248 PM EDT Tue Sep 17 2024

The period will begin with an upper trough extending from S New
England to the E Gulf of Mexico. This feature will weaken and shift
slowly SE into the weekend as high pressure builds E along the Gulf
Coast. At the surface, a weak quasi-stationary front across the S
portion of the area will push SE as high pressure builds along the
Eastern Seaboard. This setup will produce a CAD wedge along the E
side of the Appalachians as we get late into the weekend, with cooler
temperatures and more clouds late in the period. Mostly dry
conditions are expected through the period.

Thursday`s highs will range from the mid 70s in the NE mountains
to the mid to upper 80s across the remainder of the area. These
temperatures will generally persist into Saturday, with highs by
Monday about 3 to 5 degrees cooler across most of the area.
Overnight lows will range from the upper 50s in the NE to the mid
60s across the S through the weekend, with slightly cooler lows by
early next week. /SEC

MVFR ceilings rotating around the backside of the low center over
the Carolina`s. These clouds are mainly getting into the ATL/AHN
areas and affecting those TAF sites. BKN to OVC ceilings are moving
in but they are also slowly lifting into the VFR range. Will see some
more MVFR ceilings move in a few hours before sunrise Wed but they
should also lift and diminish by late Wed morning. The light showers
that were moving into the ATL area have dissipated and not expecting

stay there before turning to the NE Wed afternoon. Wind speeds are in
