.SHORT TERM...
(This afternoon through Monday)
Issued at 129 PM EDT Sun Jun 28 2026

An amplifying ridge continues to spread eastward, increasing
temperatures through central and northern Georgia. At the surface,
high pressure centered over the Gulf remains relatively in place
through Monday. The  main concerns today and Monday are the heat.
With the height rises from the ridge, confidence is increasing for
heat indices of 103-105 with more widespread 105+ from the Atlanta
Metro and south, with the higher heat indices further south. With
this, a Heat Advisory is in effect through 8 PM and a new Heat
Advisory will be in effect for the majority central Georgia
including the Atlanta Metro from 12 PM through 8 PM.

Additionally, as the high shifts eastward, showers and thunderstorms
are possible on the eastern fringe for the far northern Georgia
locations. Current guidance shows decent instability but weaker W/NW
winds, an environment not particularly favorable for severe weather.
At this time, guidance depicts a few scattered showers popping up
this afternoon ahead of a cluster of thunderstorms diving down from
Tennessee into the evening hours. Given the location of the surface
high, the higher chances (30-50%) are concentrated in the northern
counties. Though unlikely, cannot rule out a brief strong storm this
evening. As for Monday, another slight chance (15-30%) for scattered
showers and thunderstorms, mainly across central and eastern Georgia.

.LONG TERM...
(Tuesday morning through next Saturday)
Issued at 129 PM EDT Sun Jun 28 2026

No major chances to notate in the extended period. High pressure
remains dominate over Georgia for the rest of the week as the center
of the H500 ridge stays over the gulf coast states, only shifting
northeast towards the Mid Atlantic region at the end of the week.
Many locations in the CWA will host 850 mb temperatures around 20
degrees Celsius through the rest of the week for the late afternoon
hours. This combined with >590 decimeter heights will support hot
high temperatures over much of Georgia. On average, highs will top
out in the mid to upper 90s for the week, lows may only fall to the
lower or mid 70s. High-end relative humidity also prevails over the
CWA, which leads to the main impact this week: Hot heat indices over
100 degrees each day, and for some locations over 105 degrees. Heat
safety precautions are still encouraged as heat product issuance
seems likely for the next several days.

Despite high pressure lingering over the region, daily thunderstorm
chances are still present through the week. General thunderstorms
are expected with isolated to scattered coverage shifting through
the FA depending on the day. Strong mid-level theata-e values will
support convective development off the axis of the high pressure
center. However, diurnal heating will need to overcome strong
inhibition in order for convective initiation to be achieved.

.AVIATION...
(18Z TAFS)
Issued at 128 PM EDT Sun Jun 28 2026

VFR conditions prevail through all TAF sites through the period. A
few scattered showers and TSRA are possible for the northeast sites
through this evening. Confidence is higher at KAHN so a PROB30
remains from 22z-01z. KATL could have a pop-up shower through this
afternoon, but confidence is very low to warrant anything other than
a VCSH. Confidence remains too low for a TAF mention at KATL for
TSRA/VCSH on Monday afternoon as well. Winds toggle W/NW through
this evening. Expect gusts of 15-25kts through 00z before
diminishing overnight. A few sites could have calm or light/VRB
winds overnight before all sites picking up again out of the NW
between 13-15z Monday. Widespread cu field expected so kept a
FEW/SCT040 for most sites Monday.

//ATL Confidence...18Z Update...
High confidence on all elements.
