.KEY MESSAGES...
Updated at 307 PM EDT Fri Jun 13 2025

  - Scattered showers and thunderstorms peaking during the
    afternoon through the next week. A few may be strong gusty 
    winds, localized heavy rainfall, and frequent lightning.

  - Numerous rounds of showers and thunderstorms through the
    weekend and early next week may lead to localized flooding 
    and lightning may pose a hazard to outdoor activities.

.SHORT TERM...
(This evening through Saturday)
Issued at 307 PM EDT Fri Jun 13 2025

Continued robust southwesterly flow from the cutoff low over the 
gulf will bring several rounds of showers and thunderstorms across 
the area. Coverage will be patchy with a summer-like pattern, though 
high PWATS and the approaching low will drive generally increasing 
coverage through the weekend. Thunderstorms this afternoon are 
likely to be more organized than yesterday with a passing shortwave 
currently over western AL and TN alongside effects from sea breeze 
convection from the southeast. A few light showers have already 
begun to pop across central and north GA where SFCCAPE values 
currently sit at nearly 2000-3000 J/Kg. Storm potential is expected 
to peak each afternoon with diurnal heating and taper off through 
the late evening. A few storms could become strong with locally 
heavy rainfall (could lead to localized flash flooding), frequent 
lighting (an issue for many who plan to be outside this weekend), 
and locally gusty winds (40-50mph). Widespread or organized severe 
is not anticipated at this time with DCAPE values less than 900 
J/Kg, but water loading could lead to a very isolated threat for 
damaging winds.

While temperatures won't be anything too impressive, dewpoints in 
the 70s and highs in the 80s will mean apparent temperatures reach 
into the 90s by the end of the weekend. Stay hydrated and be aware 
of how much time you spend outdoors.

.LONG TERM...
(Sunday morning through next Thursday)
Issued at 307 PM EDT Fri Jun 13 2025

With persistent troughing extending from the Great Lakes towards the 
Lower Mississippi River Valley, southwesterly upper level flow will 
remain in place over the region on Sunday and into next week, which 
will keep conditions wet and humid across north and central Georgia. 
Continued advection of warm and moist air from the Gulf will keep 
dewpoints in the low to mid 70s and precipitable water values mainly 
between 1.75 and 2 inches during the weekend and through the early 
parts of next week. Chances for showers and thunderstorms will be 
higher than normal each day given this ample moisture. Convective 
activity will be largely diurnally driven, with low PoPs through 
much of the mornings, increasing through the early afternoons, and 
peaking between 60-70% in the mid to late afternoon hours each day. 
The southern end of a surface low (to the east of the trough) 
advancing through the Tennessee Valley region on Sunday afternoon is 
expected to provide additional lift and contribute to locally higher 
PoPs across the northern tier. 

While the threat for organized severe weather will be low, a few 
storms each day could become strong and capable of producing 
frequent lightning and gusty winds. Furthermore, with high PWATs, 
these storms will be efficient rainfall producers, which could lead 
to isolated flooding concerns. As the wet pattern continues, 
antecedent soil conditions will become more saturated in 
locations that see heavy rainfall accumulations over the course of
multiple days, and the probability for flash flooding will 
progressively increase as a result. Patchy fog will also be 
possible during the overnight and early morning hours, 
particularly where soils are saturated from previous rainfall and 
cloud cover dissipates.

Considering the chances for showers and thunderstorms each day and 
the associated cloud cover, high temperatures will run near normal 
for mid-June on Sunday, in the 80s across the majority of the area 
area. Temperatures will begin to climb in the early portions of next 
week, particularly to the south of the Fall Line, where highs will 
rise into the low to mid 90s. These temperatures, combined with the 
aforementioned dewpoints, will contribute to maximum heat indices of 
98-103 degrees in portions of central Georgia on Monday through 
Thursday. Low temperatures will closely reflect the dewpoints, and 
will run about 4-8 degrees above daily normals each morning.
