.SHORT TERM...
(Today through Wednesday)
Issued at 531 AM EDT Tue Jul 28 2026

The big story in the short term will be today`s heat. Afternoon
highs will climb into the upper 80s across the CWA and with
dewpoints in the 70`s we`ll have no issue reaching heat advisory
criteria for all of the CWA outside of the highest elevations of NE
Georgia. The heat is no joke, please exercise extreme caution if
decide to spend the afternoon outside.

We`ll be monitoring the potential for another MCS embedded in the NW
flow this afternoon. High res models continue to keep the worst of
it off to the east of us or falling apart before it reaches us.
These NW flow systems can be tricky to forecast tracks for but the
best chance to see thunderstorms tomorrow remains across eastern
Georgia. If the system holds together or the track shifts to include
more of our CWA the main threat will be damaging winds.

A heat advisory will likely be needed again tomorrow for the portion
of the CWA south of a line from Columbus to Macon and along the I-16
corridor. The northern CWA should expect to see drier air filter in
that will gradually bring relief from high heat indices CWA wide by

.LONG TERM...
(Wednesday night through Monday)
Issued at 531 AM EDT Tue Jul 28 2026

Into mid-week the ridge begins to push back to the west and break
down a tad pushing our area into a more dry pattern Wednesday
through Friday. With the drier air in place, dewpoints will be quite
pleasant in the low 60s across the area by Friday afternoon.Temps
will also top out in the upper 80s to low 90s across the area.
Pushing into the weekend a trough swings down into the TN/KY area
which will in turn push in a frontal boundary during this time period
which increases rain chances Saturday through Monday. Too early to
determine a severe risk if any but will be keeping an eye on this
system as it tracks into our area. Temperatures will continue to be
pleasant into the weekend with highs most days in the mid to upper
80s.
