.SHORT TERM...
(This afternoon through Tuesday)
Issued at 140 PM EDT Mon Jun 29 2026

A ridge continues to spread eastward, increasing temperatures
through Georgia. At the surface, high pressure remains the dominant
feature through Tuesday. The main concern with these increasing
heights is the temperatures and heat indices. Given the amount of
moisture return, dewpoints are elevated. This increases the heat
indices up to 109 and prompted the need for a Heat Advisory for the
majority of Georgia today. The Heat Advisory runs through 8 PM
tonight. As for Tuesday, the high pressure migrates eastward and
brings in more of a NE surface wind. Given how light the winds are
in the axis of the high pressure, not expecting as much relief in
dewpoints from the NE winds. Heat indices are expected to be
slightly lower than Monday with values in the 104-107. For this
reason, a Heat Advisory for western and into central Georgia
will be in effect from 12 PM through 8 PM.

Additionally, as the high shifts eastward, showers and thunderstorms
are possible on the eastern fringe for eastern Georgia locations.
Given the location of the surface high, the higher chances
(30-40%) are concentrated along the eastern Georgia counties.
Conditions in these locations has the better support for
instability and DCAPE. Due to the higher DCAPE, isolated
microbursts with strong to damaging winds are possible with any
thunderstorm that develops. Confidence isn't high enough to
warrant mention for the Atlanta metro, but cannot rule out a stray
shower. For Tuesday, coverage of showers is a slight chance
(25-35%) for the metro with a few more showers and thunderstorms
possible (30-50%) for central and western Georgia.

.LONG TERM...
(Wednesday morning through next Sunday)
Issued at 140 PM EDT Mon Jun 29 2026

The upper level high continues to shift northeast of our CWA for the
rest of the work week. Long range guidance suggest that the H250
high may become suppressed by the jet stream this Fourth of July
weekend and refocus over the southeast CONUS. By early next week,
models are still somewhat uncertain whether or not the ridge will
break down leading to height falls. High temperatures still look to
be above average next week as long as convective activity does not
dampen day time heating.

Wednesday through Friday, Heat indices look to be slightly lower
than the first couple of days this week due to subsidence intrusion
from the north lowering dewpoints across much of FA, mainly
throughout southern and central Georgia. Heat index values are
expected to range from upper 90s to lower 100s throughout the state
for these next few days. However, isolated locations may still reach
heat index values of 105 degrees. By the Fourth of July weekend,
temperatures are forecast to increase once again due to the high
pressure center likely shifting back over Georgia. Heat product
issuance seems probable heading towards that time frame, so heat
safety precautions will continue to be advised.

Thunderstorm chances for the rest of the workweek are focused over
our northern zones where mid-level moisture content is higher near
the southeast quadrant of the ridge axis. Once the ridge centers
back over Georgia this weekend, thunderstorm chance will also
increase for much of the CWA. Each day this week, general
thunderstorms are still expected with diurnal heating as the main
forcing mechanism. Gusty winds and lightning look to be the primary
hazards for the coming days. Timing for thunderstorms will be
confined to the afternoon and evening hours due to the nature of
their convection.

.AVIATION...
(18Z TAFS)
Issued at 118 PM EDT Mon Jun 29 2026

VFR conditions prevail through all TAF sites through the period. A
few scattered showers and TSRA are possible for KMCN/KAHN through
this evening. Confidence at this point only warrants a PROB30 for
these terminals, with KMCN going until 03z. The cu field should
diminish after sunset with mostly SKC/SCT250 overnight. Most sites
become light to VRB overnight before picking up out of the NE
Tuesday morning. Expect winds of 5-10kts throughout the day. Another
round of cu develops mid morning and into the afternoon so have
SCT040-060 beginning after 14z. TSRA chances increase after 18z for
KATL so a PROB30 should suffice for now.

//ATL Confidence...18Z Update...
Low to medium confidence on coverage/timing of TSRA Tuesday.
High confidence on all other elements.
