.SHORT TERM...
(Today through Saturday)
Issued at 157 AM EDT Fri Jun 6 2025

Key Messages:

 - A couple of strong to severe thunderstorms could produce
   damaging wind gusts in northwest Georgia between 5 PM Friday
   and 1 AM Saturday.

 - Another round of strong to severe thunderstorms is possible
   across much of north and central Georgia late Saturday
   afternoon and evening.

A quiet start to the day with patchy dense fog in north and
central Georgia, which will burn off within a few hours of
sunrise. Warm and humid, but generally rain-free conditions will
prevail through the afternoon across most of the area. One
exception could be across southern portions of central GA where we
may see a few pop-up showers or thunderstorms in the early to mid
afternoon hours. The period of most concern is in the evening and
early overnight hours, when a weak mid-level shortwave and
associated thunderstorms activity will be pushing across the TN
Valley, and may bring a severe weather threat to the area. The
Storm Prediction Center (SPC) has the I-75 corridor north of ATL
in a Slight Risk (Level 2 of 5), with a Marginal Risk (Level 1 of
5) for the rest of north and central GA. The primary hazard with
these storms would be damaging wind gusts given the linear storm
mode, meager deep-layer shear and instability. The most likely
timing for storms would be 6-10PM in NW GA, 10PM-1AM across the
Atlanta area, and after 1AM for areas south though it will be
tough for storms to hold together that long.

Warm and humid conditions continue on Saturday, with another,
more potent mid-level shortwave expected to push across the TN
Valley into Georgia during the afternoon and evening hours. This
wave will support a more favorable environment for severe weather
than on Friday as the timing will coincide with peak heating and
tap into greater instability. While a few showers and storms may
develop ahead of the shortwave, CAM guidance continues to show a
MCS (line of strong storms) along the leading edge of the wave
pushing across most of north and central GA. The primary hazard
with these storms would be damaging winds, but the environment
could also support large hail and a brief tornado. SPC has
maintained a Slight Risk (Level 2 of 5) across all of the area,
and the most likely timing of concern would be the 2PM-10PM
timeframe.

High temperatures each day will be in the upper 80s to around 90,
with dewpoints near 70F making it feel like the mid 90s during
the afternoon. Overnight lows will only drop to the low 70s.

.LONG TERM...
(Saturday night through Thursday)
Issued at 157 AM EDT Fri Jun 6 2025

Key Messages:

 - Diurnally driven showers and thunderstorms expected through
   the extended period.

 - Best severe storm potential expected Sun through Wed.

No major changes made to the extended forecast. Diurnally driven
showers and thunderstorms expected to continue for the long term
forecast. By Sat night the weak frontal boundary extending across
the Mid MS river valley moves south onto N GA. This front
continues to move south Sun stalling over central/south GA through
the end of next week. By Sat night, upper level zonal flow sets
up over the southeastern states with a strong surface to upper
level ridge extending from the western gulf to the western
Atlantic. This surface to upper level pattern will keep a decent
amount of moisture streaming along the frontal boundary with
shortwave after shortwave moving through. Basically we will
continue to see more scattered to widespread shower and thunder
chances through day 7. With several disturbances forecast to pass
through the upper level flow and interacting with the frontal
boundary could result in enhanced storm coverage/intensity. The
Storm Prediction Center (SPC) has the majority of the CWA under a
slight risk (level 2 of 5) Saturday and under a 15% risk area for
Sunday. Additionally, PWs stay in the 1 to 2 inch range with some
2.5 inch values expected through Thursday.

With all this rain in the forecast, temperatures through the long
term will hover near seasonal norms (give or take 3-5 deg). This
will put highs mainly in the 80s with some lower 90s across
central GA. Lows will be in the 60s to lower 70s.

.AVIATION...
(06Z TAFS) Issued at 157 AM EDT Fri Jun 6 2025

VFR conditions to start the 06Z TAF period, but there is
potential for CIG/VIS to reduce to IFR conditions or worse
between 09-13z due to patchy fog. ISO-SCT TSRA possible at CSG
around 20-00Z, with another area of SHRA/TSRA possibly moving
into NW GA and the ATL metro in the 00-06z timeframe. Winds W at
4 to 8 kts during day and light to variable overnight.

//ATL Confidence...06Z Update...
Low confidence in VIS/CIG reductions in fog this morning, and
for SHRA/TSRA this evening. High confidence for all other
elements.
