.SHORT TERM...
(This afternoon through Sunday)
Issued at 155 PM EDT Sat Jul 4 2026

A very warm and humid airmass remains in place across North and
Central Georgia. Heat and the chance for thunderstorms will continue
to be the primary weather concerns in the short term period. A few
lingering showers and thunderstorms are possible even after dark
(through 2AM), including in and around Metro Atlanta. Certainly not
out of the realm of possibilities and definitely something to
monitor as festivities and fireworks will be ongoing at this time.

Expecting an increase in shower and thunderstorm coverage on Sunday,
especially over North Georgia, as an approaching mid-level trough
acts to increase SW flow aloft. A surface low and attendant cold
front will also be pushing southeastward acting as an additional
lifting mechanism for storm development. A few strong to severe
thunderstorms, capable of producing damaging winds up to 60 MPH will
be possible as the frontal boundary interacts with the moist
unstable airmass that will already be in place. The SPC has painted
a Marginal Risk (Level 1 of 5) area across much of North GA for
Sunday. Elsewhere (i.e. Central GA), convection will be more
diurnally driven and scattered in nature. Timeframe for highest
coverage of storms looks to be between 2-10PM, though it is
summertime and spotty pop-up showers and thunderstorms could begin
earlier and linger later. Forecast temperatures on Sunday will be
comparable today with forecast highs in the 90s outside of the NE GA
mountains and lows in the 70s. Heat indices will still range from
the upper 90s to low 100s with the highest values over parts of
Central GA. Opted to hold off on another Heat Advisory given the
uptick in precip chances and cloud cover tomorrow. Regardless it
will be hot and additional heat headlines may be warranted in the
future.

.LONG TERM...
(Monday morning through next Friday)
Issued at 155 PM EDT Sat Jul 4 2026

The upper level pattern looks to remain quazi-zonal through the new
week, with some troughing forecast in the Southeast as high pressure
becomes elongated. Summer time heat and daily thunderstorm chances
hold as the primary highlights of the extended period.

A slight down trend in ambient temperatures continues Monday onward
with highs in the 90s, barring our mountain zones. Low temperatures
and average dewpoint temperatures should also stay in the 70s next
week. Given our high relative humidity trends, heat index continues
to be the primary concern for the coming days. While most locations
in the CWA should host maximum heat indices between the upper 90s
and lower 100s, a few locations, mainly across the SE, may still
experience heat index values over 105 degrees. Despite most
temperatures being just below advisory criteria, impactful heat is
still expected daily and areawide. Continue to practice heat safety
for the coming days.

Trends of diurnally driven convection continue every day of the long
term period. LREF ensemble guidance shows a higher concentration of
QPF in NW Georgia this week compared to the rest of the FA. This is
also reflected with NBM PoPs as they consistently favor this area
for likely (55-75%) rain chances. Meanwhile, storm coverage for the
rest of the region may be more isolated than scattered.

.AVIATION...
(00Z TAFS)
Issued at 808 PM EDT Sat Jul 4 2026

VFR conditions prevail at all TAF sites through the period. VCSH at
the central Georgia TAF sites through 01-03z as TSRA chances
decrease and lingering showers diminish. Light to VRB winds
overnight with sky cover improving to BKN/SCT250. Winds pick up
Sunday morning out of the W/SW with SCT/FEW040-060 as cu pops up
again. Another round of scattered showers and TSRA during the
afternoon so a PROB30 at all sites.


//ATL Confidence...00Z Update...
Medium confidence on tsra.
High confidence on remaining elements.
