.SHORT TERM /Tonight through Wednesday Night/...

Precipitation chances increasing across the region tomorrow as
moderate mid/upper-level wave drifts westward out of the Bahamas to
the FL/southeastern U.S. coast. Not much of a surface reflection
with this feature as the region remains under the western edge of
the western Atlantic surface ridge, but ample low-level moisture and
adequate mid/upper dynamics for more widespread, but still diurnally
oriented, convection. Temperatures remain seasonably warm but
increased cloud coverage and precipitation takes just enough of an
edge off of the highs tomorrow to keep heat index values below
advisory criteria.

.LONG TERM /Thursday through Tuesday/...

The enhanced moisture advection off the Atlantic continues to keep
us in the high PWAT soup along the SW extent of the Bermuda high
thru the end of the work week. Continue to have some chance to
likely pops Thu/Fri accordingly for expected scattered to numerous
diurnally aided convection, which could have some stronger storms
with hydrometeor loaded downdrafts allowing for localized strong
gusts and efficient heavy rain. There are some subtle differences in
how far the moisture axis/drier gradient extends into the CWA as the
center of the ridge retrogrades further west later Saturday into
Sunday, but feel like it still supports general chance pops for most
of the area.

For early next week, there is an upper wave that keeps any driving
dynamics well north of the region up across the Midwest and Ohio
River Valley, but does push an elongated front/moisture axis towards
the northern CWA by late Monday or moreso Tuesday, which could stall
or drift southward across the area into midweek and be the next main
feature to focus convection.

Nothing eventful to mention with temps as they look to remain right
around climo norms thru period.

.AVIATION...
18Z Update...

VFR conditions are expected to predominate across the area through
the majority of the forecast period. Areas of MVFR or lower
visibilities will develop after 06Z. Will likely see some impacts at
the KPDK and KMCN TAF sites, with a low chance at the other sites.
Isolated to scattered convection will be confined to mainly central
Georgia and the north Georgia mountains this afternoon, diminishing
through the evening. Scattered convection Wednesday afternoon will
see more widespread distribution over north and central Georgia.
Light, 6kt or less, northeast to southeast winds will prevail
through the period.

//ATL Confidence...18Z Update...

High confidence on all elements.
