.SHORT TERM...
(Today through Saturday)
Issued at 300 AM EDT Fri Aug 15 2025

Key Messages:

 - Friday will be the warmest day this week, with peak heat indices
   over 100 degrees in central Georgia.

 - Isolated to widely scattered thunderstorms this afternoon and
   early evening.

 - Severe weather is not expected, though stronger storms could
   produce gusty winds and locally heavy rainfall.

Winds are currently light across the forecast area, at about 5 mph
or less. With few to scattered clouds at the mid levels and recent
rainfall, it will be possible to see patchy fog across portions of
the forecast area during the early morning hours, most likely across
the far northern tier and in low-lying areas in river and mountain
valleys. Hi-res guidance continues to indicate that the development
of widespread dense fog will be unlikely. Over the course of the
day, a shortwave trough will advance through the Midwest and towards
the Atlantic coast. As this occurs, a weak low pressure system will
develop offshore of the Carolina coast, with a trailing cold front
pushing into northeast part of the state. The highest chances for
thunderstorms this afternoon will be in the far northern tier,
shifting southward later in the afternoon ahead of this frontal
boundary. With 0-6 km bulk shear values less then 20 kts and 700-500
mb lapse rates less than 6.0 C/km, the threat for organized severe
weather will be low. However, ample heat and humidity will
contribute to SBCAPE values between 2000-3000 J/kg and precipitable
water values of 1.8-2.2 inches, a few storms could produce water-
loaded downburst winds up to 40-50 mph. Considering the PWATs,
stronger storms that develop will also have high rainfall rates,
which could lead to isolated flash flooding if storms persist over a
common location for a prolonged period or in higher terrain where
greater runoff could occur.

This afternoon is expected to be the warmest of the week. Outside of
temperatures in the 80s in the higher elevations of the far
northeast, highs will largely rise into the low 90s in north Georgia
and mid 90s in central Georgia. Combined with surface dewpoints in
the low to mid 70s, heat index values will climb to between 98 and
105 degrees in the peak heating hours. A few locations in the far
southeastern corner of the forecast area could briefly flirt with
105 degrees for an hour or two this afternoon. Otherwise, diurnal
mixing should lower dewpoints sufficiently to keep Heat Advisory
criteria from being reached.

Precipitation chances will gradually diminish after sunset with the
loss of daytime heating. Meanwhile, the weak cold front will become
stationary over far northeast Georgia and ultimately wash out during
the overnight hours. A stout upper ridge will be set up over the
Mississippi River Valley region by Saturday morning and persist
through the weekend. Georgia will remain on the eastern side of this
ridge on Saturday. With synoptic-scale subsidence remaining fairly
weak, ample moisture will remain in place across the forecast area
on Saturday. Diurnally-driven thunderstorms are expected once again
on Saturday afternoon, as a result, with a greater coverage expected
than today (PoPs largely between 35-45 percent). High temperatures
on Saturday will be in the low 90s. Dewpoints once again in the low
to mid 70s will contribute to heat indices in excess of 100 in
central Georgia on Saturday afternoon, but Heat Advisory criteria is
not expected to be reached.

.LONG TERM...
(Saturday night through Thursday)
Issued at 300 AM EDT Fri Aug 15 2025

Key Messages:

 - Diurnally-driven showers and thunderstorms are expected most
days, many will see little to no precipitation.

 - Temperatures will generally range from right at average to
several degrees above average.

Models remain fairly unchanged from previous forecasts with a mid-
/upper- level ridge remaining in place over the southeast CONUS and
the Bermuda high well to the east. Isolated to scattered afternoon
thunderstorms are expected each day, though many will likely see no
significant rain accumulations. Areas that do get rain could see
brief heavy rainfall of 1-2" per hour. The driest days will likely
be Sunday and Monday. A meridional trough in the subtropical jet
over the southern Appalachian will drive weak to even lightly
regressive flow aloft and bring PWATs down closer to 1.5".

Moisture is quick to return Tuesday onward, originating partly from
the midwest and partly from wrap around flow around Erin as it makes
its way north and east. No impacts are expected at this time outside
slightly increased moisture.

Overall, temperatures remain near or just above normal for much of
the period. Highs will be in the mid to low 90s and heat indices
will reach 100-105 for much of the area. As of right now, the risk
for heat indices of 105+ remains spotty so heat advisories are not
anticipated at this time.

(18Z TAFS)
Issued at 145 PM EDT Fri Aug 15 2025

Scattered thunderstorm activity is expected in north and central
Georgia through 04Z Saturday. Impacts are expected for the TAF
sites, especially between 22Z today and 02Z Saturday. Heavy
downpours leading to visibility restrictions and gustys winds can
be anticipated. Patchy fog may develop between 08Z and 14Z
Saturday. Winds will continue be from the north at 2 to 8 kt
through 01Z Saturday. Then after 14Z Saturday northeast winds of 2
to 8 kt are expected. Light winds are expected between 01Z and 14Z
Saturday.

//ATL Confidence...18Z Update...
Moderate confidence in the occurrence of storms between 21Z today
and 03Z Saturday.
High confidence in the wind forecast.
