What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Atlanta, GA wrote its last area forecast discussion before this river flood warning went out at Nov 13, 2:44 PM EST, 3 hours 10 minutes earlier.

Area forecast discussion, Nov 13, 2:44 PM EST, 3 hours 10 minutes before
Area Forecast Discussion
National Weather Service Peachtree City GA
244 PM EST Tue Nov 13 2018

.SHORT TERM /Tonight through Wednesday Night/...

Forecast continues to evolve essentially as expected. Somewhat of a
lull in rainfall today through tonight as the deep upper low settles
into the lower Mississippi Valley. More heavy rainfall develops
across the region tomorrow through tomorrow night under strongly
diffluent upper flow ahead of the upper low. PWs remain well above
seasonal normals and strong upper forcing combined with strong
isentropic lift should provide for a prolonged period of moderate to
occasionally heavy rain by midday tomorrow through much of Wednesday
night. Instability is forecast to be minimal at best so I am not
expecting much if any thunder or severe potential. Biggest threat
will obviously be flooding. Some models hinting at a brief threat
for some wintry precipitation tomorrow evening in the extreme
northeast, but potential appears too low to include in the forecast
weather grids at this time.

20

.LONG TERM /Thursday through Tuesday/...
Extended period begins with the culprit upper low exiting through
KY and Eastern TN and much of the moisture exiting to the east
with it. Mid level dry slot looks to work into the region during
the day Thursday from west to east so there should be a relatively
quick shut off to the rainfall. Late Thursday there appears to be
a window where there is enough wrap around moisture and cold air
across North GA that some snow showers could start mixing in.
Model soundings for that area suggest a shallow but saturated
subfreezing layer below about 850mb with drier air above it which
favors upslope snow showers. Have added snow showers which would
be more likely in the NW facing slopes during the evening hours on
Thursday into the first part of the overnight. Because the low is
rapidly exiting to the east...much of moisture evacuates quickly
with it so the window looks to be only about 6-9 hours or so. Have
not included any appreciable amounts but would not be surprised
to hear about a trace or dusting in some of the higher elevations.
Not anticipating any issues with the snow otherwise.

By Friday...zonal upper flow and dry conditions set the tone for
what should be a nice weekend. Temps look to be near normal for
the weekend after a cold start Friday AM.

A weak upper level system works through the flow on Monday.
Models suggest that it will be moisture starved and may only bring
some clouds and low end rain chances.

.HYDROLOGY...

Highest rainfall amounts are oriented from our west-central Georgia
counties northeastward into east-central and northeast Georgia.
Soils remain moist enough and stream flows are already high enough
across northwest Georgia to include all but our extreme southeast
counties in a new Flash Flood Watch beginning early Wednesday
morning and continuing through the overnight hours into early
Thursday morning.
