Area Forecast Discussion...Updaged for Aviation
National Weather Service Peachtree City GA
750 AM EDT Mon Sep 21 2020

.SHORT TERM /Today through Tuesday/...
Tropical Storm Beta is currently drifting to the west..off shore of
the Texas coast. The main effect of this for our area is a
persistent layer of mostly cirrus clouds. Otherwise...upper ridging
from the Great Lakes to the Gulf will continue to give our area dry
weather through the period. Cooler temperatures and low dew points
will be maintained by low level easterly winds ridging down the
eastern seaboard and along the Appalachians. Expect some wind gusts
today...but winds should diminish later this afternoon.

.LONG TERM /Tuesday Night through Sunday/...
The start of the long term period continues to be dry through Wednesday
as we continue to watch how the remains of Sally will effect the
forecast area after Wednesday.

The current NHC forecast has Beta hitting the TX coast late today
and then taking a turn to the east and moving to the lower MS valley
late Thursday as a much weaker post tropical depression. This likely
means that Beta`s overall impacts will be minimal except for
increasing shower chances across the area.

Shower chances begin to increase Wednesday night favoring the western CWA
and continue to increase on Thursday, then continue into Friday as moisture
associated with the remains of Beta move to the area.
At this point, while a moist southerly flow continues, the pattern aloft
is a battle of an upper level trough to the NW and upper ridge to the SE
with the trough eventually winning out come Sunday and as usual with model
differences between the GFS and European.

There does not appear to be any instability for thunderstorms until Friday
and later when sufficient instability for storms moves over the area.

At this time, N GA is most likely to get the best rainfall with 1
to 3 inches possible in the Wednesday night through Friday
timeframe and less overall for central GA.
