* Through Saturday morning

* Widespread rainfall will continue across portions of Georgia
  today. Rainfall will be heavy at times. Two to five inches of
  rainfall have already fallen across much of the area, and
  additional rainfall amounts of up to 1.5 to 2 inches are 
  expected through Saturday morning with isolated higher amounts 
  likely. 

* Soil conditions remain very moist and river levels remain high 
  across the area. Even a relatively small amount of rainfall 
  will produce significant runoff and flooding of creeks and 
  rivers. Even after the rain ends, high water could persist for 
  several days after. 

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.

.PREV DISCUSSION... /Issued 346 AM EST Wed Dec 26 2018/

SHORT TERM /Today through Thursday/...
Models all agree in bringing in the next major storm system
beginning late tonight. For today, this will likely be the last dry
day for several days as high pressure will continues over the CWA.
Changes begin tonight as the ridge of high pressure wedges into
north GA. This will increase the pressure gradient which in turn
will increase the easterly winds. The deepest moisture holds off
until Thursday morning, and with ample isentropic lift, chances of
rain will begin late tonight over the extreme western parts of the
CWA. Chances of rain will spread across the CWA and increase through
the day Thursday. Rainfall amounts on Thursday will be low with most
areas seeing 0.10" or less.

MOS Guidance continues to be running too cool on the max temps, the
NAM especially has been running 5 to 7 degrees too cold with the GFS
2 to 4 degrees too cold. Have raise max temps today to at or just a
little warmer than the GFS guidance. Have gone with a MAV/MET blend
on temps Thursday due to a change in airmass, wedge and clouds.

17

LONG TERM /Thursday Night through Tuesday/...
The primary concern for the long term continues to be multiple
rounds of rainfall and a continued flooding threat. There is also
the remote chance that we could see a few strong storms on Friday.

The first round will likely have the heaviest rainfall in the
Thursday night and Friday timeframe. The axis of heaviest rainfall
has shifted to N GA and especially the mountain counties.

A flood or flash flood watch will likely be issued as confidence
on timing and amounts improves.

There looks to be a relative lull in the rainfall late Friday and
Friday night before the next round late Saturday and more so
Saturday night into Sunday, as another surge of deep moisture
moves over the area.

Another round of rainfall looks to be in the cards Monday into
Tuesday.

This unsettled weather pattern is due to an active SW flow aloft
and eventually a front that will stall across the area Saturday
into Tuesday or there abouts.

There is also potential for strong winds at the higher elevations
of the mountains Thursday night ahead of the expected cold front
that will eventually stall across the area.

Please stay tuned to your local weather during this active weather
period.

Hydrology...
Wet conditions are expected through years end, with the most
concerning period at this time being Thursday through Friday.
The current forecast is indicating 2 to 5 inches of rainfall over
almost the entire forecast area and isolated higher amounts are
always possible, especially in the mountains. The axis of greatest
rainfall has shifted north and is centered over N GA at this time
with the greatest amounts over the mountains. Forecast amounts
through Jan 1st range from 3.5 to 5.5 inches over N GA and 1.5 to
3.5 inches over central GA. These amounts combined with already
wet to saturated soils, will greatly increase the risk of flash
flooding and river flooding over north and central Georgia. A
Flood or Flash Flood Watch will likely be issued in the next day
or so.

18Z Update...

VFR conditions are expected to continue through roughly 06Z with
MVFR ceilings spreading north across the forecast area between 06Z

more widespread light rain with patchy moderate showers spreading
east by 18Z. Winds will remain easterly, generally 5-10kt, through
00Z. East to southeast winds will increase to 8-12kt, w/ gusts 16-
22kt, developing after 00Z, increasing even further after 12Z.
