.SHORT TERM...
(This afternoon through Wednesday)
Issued at 237 PM EDT Tue Jun 23 2026

Dry and temperate conditions will prevail through the short term,
bringing a nice break to the recent humid and summery weather. In
the wake of the cold front that has cleared the area to the south
today, considerably lower dewpoints and temperatures will continue
to advect into the area into tonight. Today`s breezy conditions will
quickly settle after sunset, leading to pleasant Wednesday morning
temperatures by late June standards. Low temperatures some 8-12
degrees below normal will range from the upper 50s in parts of north
Georgia to mid 60s farther south with a few low-to-mid 50s even
peppered in across the north Georgia mountains.

Northwest flow on Wednesday is expected to bring continued dry
conditions with any southeastward-propagating MCSs favored to remain
displaced to our west across Mississippi and Alabama from Wednesday
into Wednesday night. Highs on Wednesday will largely be near to
slightly below normal in the mid to upper 80s, and drier dewpoints
in the upper 50s to low 60s will bring a more pleasant feel.

.LONG TERM...
(Thursday morning through next Monday)
Issued at 237 PM EDT Tue Jun 23 2026

By Thursday, we return to more of a typical summertime weather
pattern. Weak mid-level flow and increasing southerly flow at the
surface will bring an influx of moisture back to the area. Isolated
to widely scattered showers and thunderstorms will be possible
mainly across Central GA during the afternoon with temperatures
climbing into the upper 80s across North GA (5-7 deg cooler in the
mtns) and low 90s across Central GA. Friday will favor similar
conditions though rain and thunder chances will be a tick higher as
will temperatures. Convection may be more limited on Saturday and
Sunday as a weak disturbance translates across the southern Ohio
Valley and mid-level ridging starts to build from the west.

The main story for the long term period, particularly this weekend
through early next week, will be the heat. Latest global ensembles
are painting mid-to-upper ridging will becoming highly amplified and
encompassing much of the eastern US between Sunday and Monday. As a
result, high and low temperatures are forecast to climb a degree or
two each day through early next week (Monday). Forecast highs
between Saturday and Monday are anticipated to be in the 90s
areawide (upper 80s the mountains). Heat indices (or `feels like`
temperatures) will follow suit with values in the upper 90s to low
100s during that same period. Some locations in Central Georgia may
reach Heat Advisory Criteria (105 or higher). Summer is in full
swing so be sure to take precautions if spending any amount of time
outdoors. Let`s beat the heat this summer!
