Area Forecast Discussion...Updated for Aviation
National Weather Service Peachtree City GA
650 AM EST Fri Dec 4 2020

.SHORT TERM /Today through Saturday/...
A strong upper closed low will rotate from the lower MS River Valley
into the southern Appalachians during the short term. Meanwhile an
elongated surface short wave will cross the southeast states today.
Showers will be increasing over north and central GA today
associated with this wave. Models agree that this system will be
progressive...with rain diminishing from the west starting around
00z. Not anticipating widespread high QPF values from this system
with QPF totals ranging between 0.5 to 1.0 inch...highest mainly
over north GA. The atmosphere is generally stable ahead of the short
wave...with continued easterly winds. However...there could be some
instability developing mainly this afternoon as the warm front tries
to move north. A mention of thunder has been included for the
southern half of the forecast area during that time. As the system
moves out and northwest flow takes over...a dip in temperatures
with lows in 30s to around 40 are forecast overnight Friday into
Saturday.

.LONG TERM /Saturday Night through Thursday/...
The main concern for the long term will be Sunday through Monday as
the models are struggling handling moisture return and an upper
level trough forecast to move across the Ern U.S. All in all,
rain chances look to be on the low end and any precip amounts only
light.

One thing we will need to monitor is the potential for a rain snow
mix and a brief period of potential all snow over the NE mountains
Sunday night into Monday. At this time, potential snow accumulations
are expected to be light as well, maybe around 1/4 inch or less.

Once this upper system passes, the rest of the long term, Tuesday
through Thursday, is expected to be dry.

For the most part, forecast temperatures are expected to run within
around 5 degrees of normal.
