...Afternoon Area Forecast Discussion...

.SHORT TERM...
(This afternoon through Friday)
Issued at 238 PM EST Thu Jan 12 2023

A Tornado Watch remains in effect until 7PM EST for portions of
north and central GA.
Wind Advisory in effect until 11PM EST for all of north and
central GA.

A line of strong to severe thunderstorms is currently pushing
through NW GA (just north of the metro) at this hour. Additionally,
a smaller secondary line of strong to severe storms has also
formed out ahead of this line just NW of Macon. However, the main
front is still well to our west just now entering into NW AL per
latest MSAS analysis. The CWA remains situated in the warm sector
with SSW flow ushering in upper 50s to mid 60 dewpoints. Breaks in
the cloud cover have resulted in further destabilization across
the area with SBCAPE values ranging from 500 to 1000J/kg. Out
ahead of the primary line of thunderstorms DCAPE ranges roughly
from 600-700 J/kg. Thus, strong damaging winds remain the primary
threat. However, tornadoes are certainly not out of the question,
as this line has a history of producing tornadoes (further west in
Central AL). 0-1km SRH values per SPC Mesoanalysis range from
200-350 m2/s2 across a good portion of the area. Locally heavy
rainfall, particularly with stronger storms could also lead to
some localized flooding issues as storms moves through. So
needless to say quite an active afternoon and evening is in store
for the Peach State. At this hour there are several active Severe
Thunderstorm and Tornado Warnings currently in effect. Please stay
weather aware!

Based on latest CAMs (Convective Allowing Models) the primary line
of storms pushes through the ATL metro btwn 3-5PM and past Macon
by 6-9PM and finally clearing the area between 9PM-12AM. Winds
will quickly shift to the W following the passage of the primary
line and eventually to the NW as the cold front moves through.

Still anticipating some wrap around moisture associated with this
system as the sfc low track northeast. Height falls associated
with the upper trough will usher in colder air across the north
overnight. All of this to say, some light wintry precipitation
across North GA (better chances across the NE GA mtns) will be
possible Friday morning as temperatures will be in the 30s.

.LONG TERM...
(Saturday morning through next Wednesday)
Issued at 238 PM EST Thu Jan 12 2023

High pressure continues to dominate the weather pattern today but
things will change Sat afternoon/evening. The ridge is currently
centered over AL but will slide east overnight becoming centered
over GA Sat. It will weaken a bit as it moves east off the GA/SC
coast Sat night/Sun. This will allow the next frontal system to
move into NW GA Late Sat afternoon through Sat night.

Currently a closed low center is developing across the TX/OK
panhandles and will push eastward to the OK/MO/AR borders by 12z
Sat. The associated frontal boundary will spread moisture eastward
into N GA by late morning mainly in the form of increased cloud
cover. By Sat evening The main frontal boundary will be moving
through the MS river Valley but it will also be oriented from NE to
SW with the top end of the front pushing into NW GA at the same
time. Only areas North and West of the ATL area should see precip
Sat night with the rest of the area seeing it Sun. Instability is
fairly limited with the front so for now only going with showers Sat
night but would not be surprised to see a lightning strike or two as
it moves into the area Sun.

Temperatures tonight will dip back down into the 30s with highs Sat
mainly in the 60s. Light southerly flow sets up ahead of the frontal
boundary Sat so Sat night lows will only get down into the 40s. This
will keep any freezing/frozen precip well north of our area.

.AVIATION...
(18Z TAFS)
Issued at 1234 PM EST Thu Jan 12 2023

Mostly MVFR cigs at all sites this aftn. SSW winds are starting to
pick up with gusts nearing 25kts. Over the next few hours could
see gusts as high as 27-33kts ahead of the main line of storms
pushing through NW GA. No major changes to the timing of TSRA,
still looks to impact ATL btwn 21-00z. Could see pockets of VFR
behind the line as winds quickly shift to the WNW/NW. Though MVFR
cigs are expect to fill back in overnight through at least 12-14z
Friday. Winds will remain gusts through this later period as well
with NW winds 10-13kts with gusts nearing 20-22kts.

//ATL Confidence...Avi Update...

Medium to high confidence on all elements.
