Area Forecast Discussion
National Weather Service Peachtree City GA
927 PM EDT Fri Aug 16 2019



.UPDATE...
Weak surface trough remains situated across central GA this
evening. Most of the area has been precipitation free, but a
isolated shra/tsra have started to drift into the far eastern
CWFA. The storms should continue to feed off any lingering
instability this evening. Have tweaked pops to reflect current
radar trends. Tweaked temps too.

SHORT TERM /Tonight through Saturday Night/...

The overall forecast still looks fairly quiet through the short 
term. 

The exception would be the area generally south and east of Macon 
for the remainder of the afternoon and this evening. Moisture and 
instability will remain moderate in that area and will allow 
isolated showers and thunderstorms to develop. Drier air will 
persist over much of north GA tonight into Saturday. Forecast CAPES 
below 1000 and Lifted Index values near zero are expected for 
Saturday across the north while moisture begins to increase for 
the area from Columbus to Macon and south. Slight chance to low 
chance pops have been continued for central GA Saturday...and 
also low pops for the afternoon across the higher elevations. 

Heat Index values will exceed 100 degrees over much of central GA on 
Saturday...but should remain below advisory criteria.

Forecast high temperatures should continue mostly above normal 
areawide for Saturday.

LONG TERM /Sunday through Friday/...

A relatively unsettled pattern will characterize the long-term 
forecast period with increased rain chances through the upcoming 
week. The old stationary frontal boundary will remain situated 
across southern portions of the area Sunday, providing the focus for 
scattered showers and thunderstorms in central Georgia. 

Shower and thunderstorm chances will increase areawide by Monday and 
persist through the week as the area will be situated in the upper 
trough between ridges to our west and over the western Atlantic. 
This activity will be diurnally maximized in the afternoon and 
evening each day. With PWs gradually increasing back toward 2" by 
Tuesday, locally heavy rainfall will be possible each day. By late 
week, longwave trough over the Great Lakes may push another cold 
front toward the area area, keeping the forecast unsettled.

While temperatures will moderate somewhat with increased diurnal 
convection, highs will still run slightly above normal, generally
in the lower 90s.
