.SHORT TERM...
(Today through Tuesday)
Issued at 252 AM EDT Mon Jun 22 2026

A warm and humid start to the day across North and Central GA before
our attention turns to the potential for strong to severe storms
during the evening hours. Areas of low clouds will mix out by mid
to late morning as low-level southwest winds strengthen in
response to a system moving across the Ohio Valley. By early
afternoon, temperatures will rise to the upper 80s to low 90s,
with heat index values in the mid to upper 90s in North GA, and
low 100s in Central GA. Breezy west-southwest winds of 10-15 mph
with gusts of 20-25 mph will try to provide a bit of relief from
the heat. From mid to late afternoon, showers and storms will
begin to popup as diurnal heating and instability peak. Coverage
will be generally isolated in Central GA, and scattered in North
GA. While a few of these storms could be strong with gusty winds,
heavy rain, and frequent lightning, the better chances for strong
to severe storms will be during the evening to overnight hours.
This threat will be from a potential line of storms moving in
from TN/AL ahead of a frontal boundary. Damaging wind gusts would
be the primary concern with this line of storms, though a brief
tornado cannot be ruled out. Additionally, localized flash
flooding may become a concern due to high rain rate showers and
storms repeatedly moving over areas. Model guidance has quite a
bit of spread on potential timing of this line, but generally
shows it entering far NW GA in the 7-9PM timeframe, reaching the
Atlanta metro between 9PM-12AM. The line would likely be weakening
as it moves through, falling apart over Central GA with the loss
of daytime heating and weaker forcing.

The frontal boundary will push across North and Central GA
throughout Tuesday, with northwest winds and a drier airmass
aloft moving in behind it. This will lead to a mostly rain-free
day, especially in North GA where PWAT values fall to around
1.25". Depending on how quickly the boundary gets through Central
GA, a few showers or storms could be around during the afternoon
and evening. High temperatures will be a little cooler, climbing
into the mid to upper 80s, with heat index values in the low 90s
in North GA, and mid to upper 90s in Central GA.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 252 AM EDT Mon Jun 22 2026

By Wednesday, the whole CWA will return to an afternoon `chance`
for storms as the state slowly heats back into the 90s over the
rest of the week.

Speaking of temperatures, we`re expecting highs in the upper 80s
and lower 90s through the week, though conditions will likely feel
pretty muggy as SW flow provides a near continuous stream of
moisture out of the Gulf. Apparent temperatures could reach
triple digits for parts of central Georgia on Thursday and become
more likely and more widespread over the weekend.

Overnight lows will likely remain muggy as well, with lows in the
upper 60s and low 70s. Light and variable winds won`t do us any
favors and do little in providing a relief from the heat that`s
expected to build in. Stay safe if you have outdoor plans as the
heat index looks like it will be the highest it`s been in 2026.

.AVIATION...
(06Z TAFS)
Issued at 140 AM EDT Mon Jun 22 2026

VFR to start the period in most areas, before widespread MVFR to
IFR CIGs develop and likely impact most sites. CIGs will slowly
lift back to mostly VFR by 16-17Z. ISO SHRA/TSRA around North GA,
including ATL area sites, from 16Z to 00Z, before a potential
line of strong SHRA/TSRA moves in from the north around 00-06Z.
Winds light out of the W-SW early this morning will increase to
10G20KT around 15Z and remain breezy through the evening.

//ATL Confidence...06Z Update...

Medium confidence in CIGs through the period, and timing of TSRA.
High on other elements.
