.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.
