...FLASH FLOOD WATCH IN EFFECT THROUGH TUESDAY EVENING...

The National Weather Service in Peachtree City has issued a

* Flash Flood Watch for much of north Georgia...generally north of
  a Franklin to Jonesboro to Athens line.

* Through Tuesday evening

* The first round of heavy rain will be moving in this afternoon
  and continue through midday Tuesday. Two to four inches of rain
  is expected with local amounts approaching six inches. With
  saturated soil and very high streamflow, runoff from the heavy
  rain will be enhanced, leading to a greater threat of flash
  flooding.

* Flash flooding and minor to moderate flooding of larger creeks
  and rivers is expected. This will 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.

This Flash Flood Watch replaces the Flood Watch issued for 
much of north Georgia.

Area Forecast Discussion...UPDATED
National Weather Service Peachtree City GA
1209 AM EST Sun Feb 9 2020

.UPDATE FOR AVIATION...

PREV DISCUSSION... /Issued 903 PM EST Sat Feb 8 2020/

UPDATE...

Lower visibilities spreading much quicker and more widely than
anticipated, had to go ahead with a Dense Fog Advisory for a large
portion of north and parts of central Georgia for the overnight
hours.

20

&&

UPDATE...

Pool of cool/saturated air associated with the areas that received
accumulating snowfall earlier today is resulting in a persistent area
of low clouds and fog across northeast and east Georgia that is
beginning to spread back west into the Atlanta metro area. We will
need to watch visibilities across north and east Georgia for any
widespread development of dense fog, but at this time it remains a
bit patchy for an advisory. Adjusted Sky/Visibility/Weather grids and
hourly Temperature/DewPoint grids to match current and forecast
trends.

20

&&

SHORT TERM /Tonight through Sunday Night/...

A low-level shortwave trough is exiting the forecast area with
only light showers remnant in central Georgia. But in its wake
left 4-6" of snowfall in the Northeast Georgia mountains and 1-3"
in several areas of north Georgia not specifically in the higher
elevations. Even Atlanta received some aggregates ending the long
streak of no snowfall for the city.

Similar to yesterday, skies will stay locked in with low-level
cloud cover through the afternoon and begin clearing from west to
east around and just before dusk. The clearing will allow us to
cool again to near freezing for most of the area, but with melting
snow, high moisture from the rains and calm winds, several
hazardous issues could present themselves tonight including patchy
black ice for most of northern Georgia, and possible areas of
freezing fog in and along the I-20 and I-85 corridors. For now,
these threats will be discussed further in a Special Weather
Statement.

By Sunday, conditions should begin to improve with highs rising to
the mid-50s to mid-60, clear skies, and the last day for a while
with no precip. Monday, the next deluge begins.

Thiem

LONG TERM /Monday through Saturday/...

Main concerns in the long term period is heavy rain and flooding.
12Z guidance continue to indicate an extended period of strong/broad
SWly flow aloft that began in the short term period. Moisture fetch
originating from the E Pacific basin with significantly high PW
values for this time of year. As mentioned in prev discussion, the
ingredients for heavy rain and flooding coming together starting
late Monday and continuing Tuesday. 12Z guidance still indicating 2
to 4 inches mainly over north and west GA for the 36 hour period
from 12Z Mon to 00Z Wed. With extremely high streamflow and soil
moisture, runoff potential will be correspondingly high. To add
insult to injury, the SW flow stays in place and another wave
expected to bring another round of rain, potentially heavy, on
Thursday. A flood outlook (ESFFFC) was issued discussing the heavy
rain and flood potential.

The previous Long Term Discussion Follows...

SNELSON

LONG TERM /Sunday Night through Friday/...

The long term portion begins as a rare quiet period across the
forecast area but things will be changing quickly as we approach
12Z Monday. With persistent SW flow aloft, we are just going to
get system after system affecting us through the long term. This
first system looks to bring categorical pops to the northern
portion of the area for Monday. This will expand southward for
Monday night with almost all areas seeing sustained light to
moderate rainfall. With the copious amounts of rain seen the last
few days, it will not day much to add to the hydrology concerns
already being experienced across the area. As a result, the
northern zones have already been placed in a moderate risk
excessive rainfall for day 3.

Front stalls over the area as SW flow aloft just prevents fronts
from making it through. Continued categorical pops and very
unneeded rainfall in the offing for Tuesday as well. As a matter
of fact, taking into account Wednesday rainfall along the front,
models are indicating another 3 to 6 inches of rain north of I20.
Will almost certainly need another flood watch with subsequent
forecasts.

Will be carrying thunder primarily for Central portions on
Wednesday but no severe is anticipated at this time. System
finally exits on Friday with high pressure building in its wake.
This again could be short lived as another gulf system looks to
bring additional high rain chances to the area per the GFS ECMWF
is decidedly less bullish on this feature and will use a blend for
now.

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

.DAY ONE...Tonight...

...Winter Weather Advisory In Effect For Portions of North Central
and Northeast Georgia...

A Winter Weather Advisory is now in effect for portions of North
Central and Northeast Georgia until 8 PM this evening. While the
snow has ended, many roads will remain slick and hazardous,
especially where heavier snow was observed.

Tonight temperatures are expected to drop below freezing for North
and portions of Central Georgia roughly north of a line from La
Grange to Macon to Jefferson which may cause hazardous road
conditions. Black ice will be possible where water from rains or
snow melt refreezes on untreated roadways creating slick
conditions. Calm winds and some clearing skies will also allow
for some patchy fog development over parts of north and central
Georgia tonight. Where temperatures drop to near or below
freezing, there is a chance that some freezing fog could develop
which could also cause roads, bridges and overpasses to become
slick.

Please use caution and monitor latest conditions before driving
tonight and Sunday morning.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

On Sunday morning, road conditions may continue to be slippery
from black ice and patchy freezing fog from the overnight hours
until approximately 10 AM when temperatures rise above freezing.

Additional moderate rainfall from multiple storm systems will
exacerbate ongoing flooding issues through much of next week. This
will be especially true on Monday when a moderate risk of
excessive rainfall will be in effect and widespread 2 to 4 inches
will be possible on average over a 36 hour period with locally
higher amounts possible. With extremely high streamflows and soil
moistures, runoff will pose a threat for flooding in urbanized
and low-lying areas. as well as streams and creeks that react
quickly to high rainfall amounts, and rivers with already high
streamflows.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed through tonight.
