Area Forecast Discussion
National Weather Service Peachtree City GA
338 AM EST Thu Feb 21 2019

.SHORT TERM /Today through Friday/...

Band of showers and isolated tstorms has becoming stationary. This
area of showers will begin moving northward as the next short wave
approaches from the west. This next short wave will bring an
increase in moisture across west central GA this afternoon and then
lift into north GA tonight before exiting. The stationary front
across central GA will hold into this evening, then as the surface
high builds into the northeast U.S. tonight, a backdoor front will
move across the CWA Friday wedging the CWA. There will still be
plenty of isentropic lift over the wedge and this will keep chances
of rain continuing, although amounts on Friday will be a half inch
or less.

Dense fog has developed across parts of central GA and this will
continue into mid morning. Will therefore continue the Dense Fog
Advisory for this morning.

Rainfall amounts today should remain below 1 inch across the CWA,
however with the ground already saturated, it will not take much
rainfall to push a creek or river into flood, especially with a
thunderstorm that could produce higher amounts. Will therefore
continue the Flash Flood Watch for today.

&&

.LONG TERM /Friday Night through Wednesday/...

The long term period begins with a wedge setting in to NE Georgia in
addition to a stalled front just north of the area. With
southwesterly flow pushing moisture into the area, chances for
showers will continue through Saturday, with the highest chances
across northern Georgia. High PWs and instability will continue the
potential for periods of heavy rain and isolated thunderstorms
across the area. 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.

Chances for showers and thunderstorms increase across the entire
area for late Saturday/Sunday as a cold front pushes through the
area on Sunday. QPF totals are currently around half and inch to
an inch with the highest totals across northern GA. With already
saturated soils across much of northern Georgia concerns for river
flooding and flash flooding will continue. After this system
clears the area late Sunday, we should see some drier weather on
Monday and for some areas part of Tuesday as high pressure pushes
into the area. Models then show a wave moving north from the gulf
into the area on late Tuesday into Wednesday, but models differ
on northward extent as well timing of the moisture across the
area. At this point have only included slight chance pops across
the area.

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

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

.DAY ONE...Today and Tonight...

A Dense Fog Advisory is in effect until 10 AM this morning across
portions of central Georgia. Visibilities may be reduced to a 1/4
mile or less.

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

The Flash Flood Watch continues until this evening for most of
North Georgia including the Atlanta metro, where 1 to 2 with
locally higher amounts are possible. 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...Friday through Wednesday...

An increased threat for river and stream flooding will continue
through the week and weekend 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 Saturday and
Sunday

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed through tonight.
