Area Forecast Discussion
National Weather Service Peachtree City GA
352 AM EDT Sun Aug 9 2020

.SHORT TERM /Today through Monday/...
An upper ridge will build across the southeast through the short
term. The remnants of a surface boundary persists across central GA.
An unstable air mass and diurnal heating will support isolated to
scattered convection this afternoon into the evening...mainly across
central GA. Not much change expected for Monday. Slight chance to
chance pops for the afternoon with diurnal heating. Somewhat
higher pops east central associated with a sea breeze. Models
hint at the possibility of a convective complex late tonight into
Monday as a short wave moves southeastward from the Mid MS Valley
into the southern Appalachians. Have left low pops through the night
into Monday morning mainly north GA. Otherwise not confident at this
time to try and refine pops any more. Heat Index values are forecast
to remain below advisory criteria today and Monday...ranging from
100 to 103 mainly across central GA.

.LONG TERM /Monday Night through Saturday/...
A somewhat typical summertime pattern will be in store for
the long term highly characterized by weak flow aloft and broad
weak surface high pressure with an embedded surface trough.
The nature of the upper flow could allow for weak short waves to
move to the area that would enhance the chances for showers and
thunderstorms along with daytime instability. The shower and
thunderstorm chances will favor the afternoon and evening but not
necessarily end at night. Model guidance is increasing the overall
moisture and this will lead to higher rain chances during the coming
week.

Aiding the shower and thunderstorm chances will be high temperatures
in the 90s for much of the area away from the mountains. This
will allow for heat indices in the 100 to 105 range for much of the
area through late week. Tuesday through Thursday looks to be the
hottest with spotty heat indices of 105 to 110 over some locations
of central GA.
