...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH WEDNESDAY
AFTERNOON...

The Flash Flood Watch continues 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...Baldwin...Butts...Jasper...Jones...Monroe 
  and Putnam. In east central Georgia...Greene...Hancock... 
  Taliaferro...Warren and Wilkes. In north central Georgia... 
  Barrow...Cherokee...Clayton...Cobb...Dawson...DeKalb... 
  Douglas...Fayette...Forsyth...Gwinnett...Hall...Henry... 
  Morgan...Newton...North Fulton...Pickens...Rockdale...South 
  Fulton and Walton. In northeast Georgia...Banks...Clarke... 
  Jackson...Madison...Oconee and Oglethorpe. In northwest 
  Georgia...Bartow...Carroll...Chattooga...Floyd...Gordon... 
  Haralson...Paulding and Polk. In west central Georgia... 
  Coweta...Harris...Heard...Lamar...Meriwether...Pike... 
  Spalding...Talbot...Troup and Upson. 

* Through Wednesday afternoon

* A cold front will move southeast across the forecast area
  through Wednesday. Additional rounds of locally heavy rainfall
  are possible across much of north and central Georgia. Rainfall
  amounts of one to two inches will be possible, with locally 
  higher amounts possible. Soils remain saturated and several 
  rivers, creeks and streams remain near or in flood, so any 
  additional rainfall will only create run off and exacerbate 
  ongoing flooding conditions.
  

* Flash flooding and minor flooding of larger creeks and rivers 
  is possible. This may close some roads and could flood homes 
  and businesses in flood-prone areas. Along larger creeks and 
  rivers, flooding could last for several days. 

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.

The Flash Flood Watch for portions of north and central Georgia 
has been cancelled. Earlier heavy rainfall has ended and only
light additional rainfall totals are expected through Wednesday

or near flood, with runoff from recent rainfall expected to lead
to continued river flooding conditions.

Area Forecast Discussion

.UPDATE...

12z Aviation update below.

.PREV DISCUSSION... /Issued 415 AM EST Tue Feb 18 2020/

..Morning Area Forecast Discussion...

SHORT TERM /Today through Wednesday/...

Main focus dominating the short term is with expected widespread
showers and slight thunderstorm potential driven by an initial upper
shortwave today. The area of precip is currently pushing into the
western CWA at the time of this discussion and has had some
persistent isolated embedded lightning with an axis of elevated low
end CAPE. While the shear params remain limited, no strong to severe
intensity is expected and should be just general thunder. Behind
this initial wave, the upper SW flow and Gulf moisture transport
will continue along and ahead of a cold front progged to push
relatively slowly southward across the area late tonight into
Wednesday. Overall total QPF looks to be 1.5 to 2 inches across the
northern majority of the area with the heavier amounts likely today
into tonight. PWATs do look to be quite high and supportive of
highly efficient rainfall, close to 1.5 inches and upwards of 1.75
inches into some central/southern portions of the CWA, which could
even flirt with climo records. Have opted to hold off on any flood
watch given uncertainty with how much rainfall occurs with the
initial wave. Future updates may warrant a possible issuance if
amounts trend higher.

While temps should be decently above normal today with highs in the
mid to upper 60s for most areas (even low 70s across the south), the
aforementioned fropa will limit north GA to the low to mid 50s on
Wednesday.

Baker

&&

.LONG TERM /Wednesday Night through Monday/...

We begin the long term period on Wednesday Night with what is
likely to be a slight break in between two rounds of heavier
rain. At mid-levels, drier air will have pushed southward to its
most southern extent before a surge of moisture moves back into
the southeast for a second bout of rain showers in the region from
early Thursday morning through Thursday Night. This round of rain
is likely to drop another 0.5-1 inches of rain across central
Georgia. In recent model runs, there have been hints of a possible
mix of wintry-type precip for far Northern Georgia from Thursday
morning to Friday morning with residual showers. However,
temperatures are expected to be above thresholds for frozen
precipitation to make it to the ground at this time; this occurs
even in model runs producing frozen precip with vertical profiles
that would suggest melting. For now the only expectation for
wintry precip will be for the highest elevations in the mountains
on late Thursday night but conditions will need to be monitored
going forward.

Going into Friday and the weekend, we'll have our first break from
precip in the forecast! Highs will be on the increase with high-
40s/low-50s on Friday and low- to mid-50s on Saturday under mostly
clear skies and a stout, surface high pressure. Moisture comes
back into the area on Sunday with PWATS rising from 1/8 of an inch
to over an inch. This moisture will be overriding a warm front set
to arrive on Monday, but the parent low pressure system in the
northern plains is set to occlude and stall, possibly keeping the
southeast under cloudy skies and showers for several days after.

.AVIATION...
12Z Update...
Most sites should have LIFR cigs in 200-400 ft range this morning
that could persist into much of the day and only possible slight
improvement to IFR around 500-800 ft late afternoon or within the
area of SHRA (precip likely thru majority of period), then back
to LIFR after 03z Wednesday. Generally IFR vsbys around 2 SM but
could have greater in breaks of precip. TS chance a bit too low to
include but may warrant tempos in updates. Winds initially east
to SE 5-7 kts with SSW shift after 17z and WNW shift with front by
06z Wed for KATL and nearby sites.

//ATL Confidence...12Z Update...
Medium on overall cig/vsby trend.
High on all else.

This Hazardous Weather Outlook is for portions of North and Central Georgia.

.DAY ONE...This Afternoon and Tonight...

There is also a slight chance of thunderstorms across parts of
north and central Georgia today and tonight. Some storms could be
strong to severe with the main threat being damaging winds. Heavy
rain will also be possible with these storms and ponding on
roadways and some nuisance flooding may be possible, especially in
low-lying or highly urbanized areas.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday...

Periods of possible heavy rain could occur through Thursday.
Please monitor forecast updates if there is an increased threat of
flooding. Also, the interaction of some colder air could allow
for some transition to light snow in parts of far northeast
Georgia for Thursday evening. Some light accumulations cannot be
ruled out so please monitor future updates. Otherwise, no
hazardous weather is expected at this time.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed through tonight.
