...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH THIS EVENING...

The Flash Flood Watch continues for

* Portions of north central Georgia...northeast Georgia... 
  northwest Georgia and west central Georgia...including the 
  following areas...in north central Georgia...Barrow... 
  Cherokee...Clayton...Cobb...Dawson...DeKalb...Douglas... 
  Fannin...Fayette...Forsyth...Gilmer...Gwinnett...Hall...

  Dade...Floyd...Gordon...Haralson...Murray...Paulding...Polk... 
  Walker and Whitfield. In west central Georgia...Coweta and 
  Heard. 

* Through this evening

* Soil conditions remain very saturated and river levels remain
  high across the area. The potential for locally heavy rainfall
  will continue through this evening. Rainfall totals up to an 1",
  with locally higher amounts possible in any stronger storms.
  This amount of rainfall will produce significant runoff and
  flooding of creeks and rivers. 

* Periods of heavy rain can overwhelm or clog storm drains and 
  ditches with debris and cause extensive street flooding and 
  road ponding. This is especially true this time of year as 
  fallen leaves block or impede drainage systems. Take time 
  ahead of the rain to clear leaves and debris from these 
  drainage systems. Due to the extremely saturated soils, downed 
  trees will be likely, even with sub severe winds. 

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.

Area Forecast Discussion
National Weather Service Peachtree City GA
643 AM EST Wed Feb 20 2019

.UPDATE...
Updated for the 12Z Aviation Discussion.

&&

.PREV DISCUSSION... /Issued 346 AM EST Wed Feb 20 2019/

SHORT TERM /Today through Thursday/...

No major changes to the overall pattern as models continue in good
agreement through the short term. The southwest flow aloft will
continue to bring abundant Gulf moisture over the CWA. The main
focusing mechanism today will be upglide along a warm front that
will push across north Georgia this afternoon and evening. Until
then, low clouds, drizzle and intermittent rain will continue across
north Georgia through this evening. The high winds experienced
earlier are diminishing and the Wind Advisory will be allowed to
expire at 12Z today.

As the warm front pushes northeast this afternoon and evening, the
atmosphere will destabilize enough to allow MUCAPES of 500-800 to
spread across the CWA. This will be enough for isolated tsra
development this afternoon and tonight.

A cold front will move into the north Georgia Thursday.
GFS/NAM/ECMWF want to push it through most of the CWA by 00Z Fri.
With a parallel flow aloft, the front may not be able to make it
through the CWA. Some of the hi-res models keep the front across
north GA Thursday and then lift it north into Tennessee late
Thursday afternoon. Due to the uncertainty, will continue with the
best chances of showers/isolated tsra across north GA.

QPF values by models and WPC have come down a little, but at this
time do not want to make any changes to the current watch timing and
configuration as this is a prolonged event.

17

LONG TERM /Thursday Night through Tuesday/...

The long term period begins with a front stalled in the vicinity as
multiple waves of precipitation impact the area. As such have kept
likely to categorical pops across northern Georgia through Saturday.
As high pressure moves off the east coast and noses down the
Appalachians, a wedge builds in on Friday and looks to remain until
Saturday. This will help to enhance precipitation across the area.
Continuous high PWs and instability will result in periods of
thunderstorms and heavy rainfall across the area through Saturday.
With multiple rivers across northern Georgia already in flood,
concerns for river flooding and flash flooding will continue as
these rounds of precipitation impact the area, especially across
portions of northern Georgia. The Flood Watch remains in effect
through Saturday morning. Make sure to stay updated to the forecast
for any changes to the watch.

The next system is forecast to impact the area late Saturday into
Sunday as a surface low develops across the midwest and pushes a
cold front through the state on Sunday. PW's remain high so periods
of heavy rainfall may be possible. Overall, instability isn't as
impressive as previous shifts, but chances for thunder remain in the
forecast. The good news is we should see some drier weather on
Monday before chances for rain return on Tuesday.

Temperatures through the weekend are expected to be mostly above
average in the 60s and 70s, aside from those within the wedge where
highs are expected to be closer to the 50s. After the weekend
system, high temperatures are expected to be closer to seasonal
norms.

.AVIATION...
12Z Update...
A mix of IFR/LIFR cigs will continue through the forecast. Winds
will be easterly with a few gusts early this morning. Winds will
become south to southwest tonight as the warm front lifts north of
ATL/AHN. Best chances of rain will be north of ATL/AHN, however
as the cold front approaches tonight, chances of rain will
increase. There is a risk of tsra this afternoon and tonight,
however risk is too low to mention in the TAF.

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

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

Strong wind gusts combined with extremely saturated soils in
northern Georgia have resulted in conditions susceptible for
trees to become uprooted and blown over. Trees may be blown onto
structures, roadways or powerlines causing further power outages
across the area.

Showers and isolated thunderstorms are expected to impact the area
this afternoon and evening. The main hazards with any storm will
be gusty winds and heavy rainfall.

A Flash Flood Watch has been issued for most of North Georgia
including the Atlanta metro, where up to 2 inches of rapidly
accumulating rainfall could occur with this evening's storms. The
Flash Flood Watch is in effect through Thursday evening, and takes
the place of the previously issued Flood Watch. As a result of
multiple periods with heavy rainfall, nearly all the rain that
will fall will be converted to runoff and some localized flooding
of creeks and streams may be possible across portions of northern
Georgia.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

The Flash Flood Watch will remain in effect through Thursday
evening, with further Flood Watches possible through Sunday
morning. Multiple rounds of rain are expected across much of the
area through Sunday, with 2 to as much as 4 inches possible by the
end of the week. The highest rainfall amounts at this time are
expected across northwest Georgia. An increased threat for river
and stream flooding will continue through the week as rain falls
over saturated grounds. Localized flash flooding will also be
possible, especially over the complex terrain of north Georgia.
Make sure to stay tuned to the latest forecasts and updates each
day for any changes to the forecast.

In addition, there is a chance of thunderstorms on Thursday afternoon
through Sunday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed through tonight.

...Strong Wind Gusts and Wet Soils Will Continue to Uproot Trees
Across North Georgia...

Wind gusts of 20 to 30 mph will be possible through the rest of
the day for portions of northern Georgia. These enhanced wind
speeds combined with extremely saturated soils from the persistent
rain have resulted in conditions very susceptible for trees to
become uprooted and blown over. Trees may be blown onto
structures, roadways or powerlines causing further power outages
across the area.
