.SHORT TERM...
(Today through Saturday)
Issued at 323 AM EDT Fri Jun 27 2025

Key Messages:

-Diurnally-enhanced scattered showers and thunderstorms again this
afternoon and evening

-Some storms may reach severe limits with the primary risk for
strong downburst wind gusts

-Additional shower and thunderstorms chances expected again for
Saturday

-Near or slightly above temperatures to continue through the weekend

Essentially a rinse and repeat forecast for North and Central
Georgia both today (Friday) and tomorrow (Saturday). The subtropical
high largely remaining situated over the western Atlantic -- with
North and Central Georgia still located on the western fringes of
the high. Thus, with little change to the warm, moist environment
daily afternoon and evening rain and thunder chances remain in the
forecast. CAPE will be on the order of 1500-2000 J/kg, though shear
will be at a minimum (less than 20kts). As in previous days,
isolated strong to severe thunderstorms remain a possibility with
downburst wind gusts being the primary threat.  The 500mb ridge
that`s been in place over the western Atlantic will begin to shift
eastward on Saturday.

Another toasty day can be expected with forecast highs climbing into
the low to mid 90s (low to mid 80s in the northeast mountains) this
afternoon. Heat index values will peak in the 98 to 101 range. While
below advisory criteria continue to take precautions if spending any
time outdoors. Forecast temperatures overnight will lower to the
upper 60s to low 70s (low to mid 60s in the northeast mountains).
Similar temperatures are expected for Saturday.

.LONG TERM...
(Saturday night through Thursday)
Issued at 323 AM EDT Fri Jun 27 2025

Key Messages:

  - Moist conditions through the long term period, with diurnally
driven convection leading to scattered to numerous thunderstorms
each afternoon/evening.

  - Organized severe weather is not anticipated at this time, though
there is some uncertainty with this potential.

As the long term period begins on Saturday night, the 500 mb ridge
dominating the eastern CONUS for much of this week will have
dampened and moved eastward away from the CONUS. A look at the 200-
250 mb level indicates the presence of a tropical upper tropospheric
trough (TUTT) over the Atlantic, which will likely retrograde
westward towards the Southeastern coast as an upper low. A moist
airmass will meanwhile be in place across much of the Southeast
through the long term period, with dewpoints in the low to mid 70s
across the majority of the forecast area (and 60s in the higher
elevations of the northeast mountains). Precipitable water values
are expected to be above average for late June/early July through
the long term period, slowly increasing from 1.75-2" on Sunday to 2-
2.25" by mid-week.

Most precipitation through mid-week appears that it will be
diurnally-driven in nature, with highest PoPs in the afternoon and
evenings each day. Given the high PWAT values, the coverage of
thunderstorms should be a bit higher than we would normally see on a
typical summer afternoon, and could also persist a few hours after
sunset. Guidance continues to indicate that the retrograding upper
low will fill in before reaching Georgia. However, it is possible
that if it makes it over the forecast area, the cooler air aloft
could promote greater instability, increased lapse rates, and a
higher chance for organized severe weather Sunday afternoon into
early Monday morning than would otherwise be expected. This mode of
uncertainty will need to be monitored as we get closer in time.

Chances for showers and thunderstorms are anticipated to increase
further on Tuesday afternoon with increasing atmospheric moisture
and the potential of a frontal boundary advancing southward through
the Tennessee Valley and towards north Georgia. Repeated rounds of
thunderstorms each day could lead to saturated soils and wet
antecedent conditions, which in turn could contribute to
increasing flash flood potential, particularly in more urban
areas. This far in advance, it is difficult to identify any
specific locations where flooding is more likely, as it will
depend on which areas see heavy rainfall totals day after day this
weekend and early next week.

With the exit of the upper level ridge impacting this week`s weather
and increased cloud cover from daily storms, afternoon highs will be
gradually lowering through the long term period. High temperatures
are forecast to be in the low 90s on Sunday afternoon and largely in
the upper 80s by Tuesday and Wednesday afternoons. In spite of the
lower temperatures, ample humidity will nonetheless contribute to
heat index values rising into the upper 90s to low 100s during the
peak heating hours.

.AVIATION...
(18Z TAFS)
Issued at 1243 PM EDT Fri Jun 27 2025

Mainly VFR conditions across the area but looking for convection
to get going in the next few hours around the TAF sites. Should
see another round of SHRA/TSRA this afternoon and evening with the
best chance for the TAF sites happening between 21z-01z (give or
take an hour or two). Winds should stay mainly out of the W-NW in
the 5-10kt range but will see some gusty winds to 30kt in and
around any convective activity. VSBYs expected to stay in the VFR
range but like the winds could see some MVFR VSBYs in and around
the afternoon and evening storms. Things expected to clear out
overnight with another round of storms Sat afternoon/evening.
