Area Forecast Discussion
National Weather Service Peachtree City GA
716 AM EDT Sat May 17 2025

...New 12Z Aviation Discussion...

.SHORT TERM...
(Today through Sunday)
Issued at 322 AM EDT Sat May 17 2025

Key Messages:

 - A line of thunderstorms will advance through far north Georgia
   during the early morning hours ahead of a cold front. A few
   storms within this line could become severe.

 - Scattered thunderstorms are expected this afternoon and evening
   in portions of central Georgia in a warm/humid environment and
   along the stalled frontal boundary.

 - Showers and thunderstorms return on Sunday, with isolated
   strong to severe storms possible. The possibility of an MCS
   entering the area will need to be monitored.

As the morning begins, a line of thunderstorms is advancing
southward through middle Tennessee ahead of a cold front. The
progression of the line has slowed a little bit compared to the
previous forecast, though a few isolated storms have begun to enter
the far northwestern corner of the forecast area. By the time storm
arrive in the far northern tier by around 4 AM EDT, SBCAPE and
MUCAPE values around 1000-1500 J/kg will still be present.
Furthermore, 0-1 km shear ahead of the cold front will range from 30-
35 kts and 0-1 km storm relative helicity values will range from 150
to as high as 250 m2/s2. Considering these factors, isolated storms
ahead of the line may become supercellular, capable of producing a
brief tornado and strong wind gusts. It will also be likely to see a
few stronger storms embedded within the greater line, with bowing
segments capable of producing damaging wind gusts and brief
tornadoes, as well. By sunrise, the line is anticipated to be
roughly parallel to the north ATL metro. At this point, the cold
front will become more elongated from west to east, at which point
it will begin to stall and storms will steadily weaken. Showers and
thunderstorms will work their way southward through the metro area
during the early and mid morning hours.

By the early afternoon, the front is expected to stall in an area
between the metro area and a line from Columbus to Macon. The
passage of the cold front will only have a minor impact on high
temperatures this afternoon. Highs in north Georgia are forecast to
rise into the mid to upper 80s in all but the far northeastern
mountains (which will be slightly cooler). To the south of the
front, highs in central Georgia will rise into the low to mid 90s
once again today. These highs will range from about 5-9 degrees
above daily averages. The frontal boundary is expected to provide a
focus for convective development during the afternoon and evening
hours. While may hi-res solutions keep convective development sparse
in the vicinity of the front, this very well may be underdone given
strong destabilization to the south of the front. SBCAPE values
between 2000-3000 J/kg will still allow for the development of
isolated to scattered thunderstorms in the afternoon hours. With
deep layer bulk shear of 45-55 kts, some of the storms that develop
will have the potential to become supercellular and produce damaging
wind gusts and hail. Because of this, the SPC has maintained a Day 1
Marginal Risk (level 1 of 5) for severe weather. Precipitation is
expected to gradually come to an end in the hours following sunset
with the loss of diurnal heating.

The frontal boundary will still be in place across central Georgia
on Sunday morning. At this time, a 500 mb ridge will advance across
the Great Plains. A quickly moving shortwave will move across the
Southeast on the eastern side of the ridge pattern, where it will
then overrun the front on Sunday morning into the afternoon. Chances
for showers and thunderstorms will increase accordingly, with
scattered showers and a few isolated thunderstorms during the
morning and more numerous showers and thunderstorms in the
afternoon. The greatest chances for showers and thunderstorms are
forecast to be in the far west/northwest portions of the forecast
area where isentropic lift will be most aligned with the stalled
surface boundary. Forcing along the front will be weak at this
point, but SBCAPE values ranging from around 1000 J/kg in far north
Georgia to 2000 J/kg in south-central Georgia and a moderately
sheared environment will allow for isolated thunderstorms to become
strong to severe in the afternoon and capable of producing strong
wind gusts.

Another variable that will warrant monitoring as we get
closer in time is the formation and evolution of any MCSs that
develop upstream overnight into Sunday morning. An MCS entering
central Georgia during the afternoon could find itself in a highly
favorable environment for downstream growth and propagation, which
would lead to a more widespread wind threat. Ample uncertainty
remains in this scenario at this time.

.LONG TERM...
(Sunday night through Friday)
Issued at 322 AM EDT Sat May 17 2025

Key Messages:

  - Warm to hot. Highs in the upper 80s and low 90s, with a
    potential cool down around mid-week.

  - Small chance of severe weather Sunday afternoon. Main hazard
    is damaging winds. There is a marginal (level 1 of 5) risk of
    severe. Risk tappers off into the evening.

Thunderstorms may continue into the evening hours on Sunday with
whatever instability may remain through central Georgia. Entering
the overnight hours, the subtropical ridge rebounds northward as the
upper level shortwave moves out of the area. Thunderstorm activity
should shift northward through this timeframe, though overall
activity will be significantly reduced. With the terminus of the
subtropical thermal ridge across north Georgia, diurnal
thunderstorms activity can be expected each afternoon Mon and
Tuesday ahead of our next system.

As we get into the Wednesday timeframe, a more robust upper level
trough will descend into the area bringing a cold front and more
widespread showers and thunderstorms. Currently limited to no severe
weather is anticipated with this due to the strength of the thermal
ridge, however will definitely keep an eye on it as we get into the
near term. Temperatures behind the front will be cool for this time
of year with highs in the 70s and (hopefully) drier conditions.

.AVIATION...
(12Z TAFS)
Issued at 707 AM EDT Sat May 17 2025

A line of SHRA/TSRA is advancing southeastward through north
Georgia and approaching the northern metro area. Prevailing -SHRA,
along with a TEMPO for TSRA, is being carried at ATL from 12-15Z
this morning. MVFR ceilings are also expected in the vicinity of
the line of precip through 17Z at ATL. Ceilings will then improve
to VFR and scatter out during the late afternoon. As the frontal
boundary stalls in central Georgia, scattered TSRA will be
possible near CSG/MCN this afternoon, warranting a TEMPO from
18-22Z. Winds through the daytime will be SW to W, at 8-12 kts
and occasional gusts up to 18-22 kts. Winds will diminish after
sunset. MVFR level clouds will be possible once again in the early
morning on Sunday, most likely in west-central Georgia.

//ATL Confidence...12Z Update...
Medium confidence on ceiling trends.
High confidence on all other elements.

This Hazardous Weather Outlook is for north and central Georgia.

.DAY ONE...Today and Tonight...

A line of thunderstorms will move across north Georgia this
morning. A few storms within this line could become strong to
severe. Damaging wind gusts will be the primary threat with any
severe storms that occur, though hail, frequent lightning, and
locally heavy rain will also be possible. A brief tornado also
cannot be ruled out.

Scattered thunderstorms are expected to develop in portions of
central Georgia this afternoon and evening. A few of these storms
could also become strong to severe, capable of producing damaging
wind gusts and hail.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

Periods of thunderstorm activity are expected between Sunday and
Wednesday, with the greatest storm coverage anticipated in north
Georgia. A couple of storms could be strong to severe during the
daytime on Sunday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not requested but spotters are encouraged
to submit reports of severe weather through the web by going to
weather.gov/atlanta.  Please relay any information about observed
severe weather to the NWS while following all local, state, and
CDC guidelines.
