...FLASH FLOOD WATCH IN EFFECT THROUGH WEDNESDAY MORNING...

The National Weather Service in Peachtree City has issued a

* Flash Flood Watch for portions of central Georgia...east 
  central Georgia...north central Georgia...northeast Georgia... 
  northwest Georgia and west central Georgia...including the 
  following areas...in central Georgia...Butts...Jasper and 
  Putnam. In east central Georgia...Greene...Taliaferro and 
  Wilkes. In north central Georgia...Barrow...Cherokee... 
  Clayton...Cobb...Dawson...DeKalb...Douglas...Fannin...

  Haralson...Murray...Paulding...Polk...Walker and Whitfield. In 
  west central Georgia...Coweta...Heard...Lamar...Meriwether... 
  Pike...Spalding and Troup. 

* Through Wednesday morning

* A frontal boundary will remain stalled across much of north and
  central Georgia through Wednesday morning. Waves of moderate to
  locally heavy rainfall are expected today through Wednesday
  morning. Soils are already saturated and additional rainfall,
  even lighter amounts, will only exacerbate run off. One to three
  inches of rain has already fallen over the southern and eastern
  Atlanta metro areas and additional rainfall amounts of one to
  two inches are possible through the remainder of the day. The
  axis of heavier rainfall is expected to shift northward
  overnight and Tuesday with additional rainfall amounts of one to
  three inches possible. Locally higher amounts, especially across
  the higher terrain of north Georgia, are also possible. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.

.UPDATE...

Updated for the 12Z Aviation Discussion.

&&

.PREV DISCUSSION... /Issued 425 AM EST Mon Jan 13 2020/

SHORT TERM /Today through Tuesday/...

The short term period begins with the warm front moving slowly
northward across the forecast area. Current radar shows a line of
showers and thunderstorms extending along an axis along and south of
the I-85 corridor along the leading edge of the frontal boundary.
Thunderstorms within this line are not severe, but are nonetheless
capable of producing locally heavy rainfall. The front, along with
the showers and thunderstorms, will continue to slowly advance into
north Georgia during the morning hours. Low clouds and reduced
visibilities have furthermore developed in the areas behind and
south of the warm front. Widespread fog is in place across portions
of central Georgia, with some locations in the far southern tier of
the forecast area experiencing dense fog with visibilities reduced
to a quarter mile or less. As a result, a Dense Fog Advisory is in
effect for those areas until 9 AM EST this morning.

Persistent southwesterly flow aloft remains in place over the
southeastern CONUS, keeping a warm, moist airmass over the region
and  contributing to dewpoint values in the low to mid 60s across
most of north and central Georgia, and precipitable water values
between 1.2" and 1.6". Later during the day today, the warm front
will stall and become stationary across north Georgia, remaining
draped across the area into Tuesday. Likely to categorical PoPs are
expected ahead of the warm front, primarily across north Georgia
through today and Tuesday, with progressively diminishing PoPs
behind the front. Deep moisture and high dewpoints as a result of
the southwesterly flow aloft remaining over the southeastern CONUS
will allow for sufficient instability to warrant isolated to
scattered thunderstorms where showers occur.

Due to the continued warm and moist flow from the Gulf, temperatures
will be well above climatological normals through the short term
period. Low temperatures this morning are expected to range from the
low 50s in far north Georgia to the low 60s in east-central Georgia.
These temperatures are 20-28 degrees higher than the daily average
across most of the forecast area. High temperatures today and
Tuesday will range from the upper 60s in north Georgia to the upper
70s in east central Georgia, between 16-24 degrees above average
area-wide.

LONG TERM /Tuesday Night through Sunday/...

Will be short and sweet here with the long term discussion given
the ongoing overnight convection across the area. The long term
period begins with a continued southern stream jet connection to
the Pacific that will bring a great deal of moisture to the area
for most of the week. Extended models in good agreement in high
levels of deep layer moisture along with occasional shortwaves in
zonal flow aloft temporarily increase rain chances.

The best chances for rain will be Tue through early Thu with main
precip axis meandering north and south through the forecast area.
Enough instability present to warrant mainly isolated thunder
chances through this period. Given antecedent conditions,
certainly could be looking at additional flooding given persistent
axis and possibility of training across the area.

High bridging across the northern tier will shunt precip south of
the area for Friday but yet another shortwave will bring another
shot of precip ahead of a front to the area for Saturday.
