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 Dec 8, 6:45 AM EST, 3 hours 20 minutes earlier.

Area forecast discussion, Dec 8, 6:45 AM EST, 3 hours 20 minutes before
Area Forecast Discussion...Updated for Aviation
National Weather Service Peachtree City GA
645 AM EST Sat Dec 8 2018

...CORRECTED...

.SHORT TERM /Today through Sunday/...
Many forecast challenges next 36 hours but primary concerns are
heavy rain and flooding potential this afternoon through
Sunday as well as winter weather p-types and accumulation(s)
tonight and Sunday.

Strong, open short wave currently located over SW TX this morning
still expected to move east across the southern states today and
tonight. With strong NW flow aloft over New England during this
time, strong cold air damming (CAD) event expected to commence
bringing very cool and somewhat drier low level air from the
northeast, which acts to increase warm/moist advection and
vertical motion. Model and guidance QPF quite impressive with
event total amounts 2.5-3.5 inches overall but the far southeast
counties. Have maintained flood watch over the entire forecast
area due to high soil moisture, streamflow and runoff potential
over middle GA from recent heavy rainfall event just last Sun/Mon.
Highest rainfall rates should occur from noon today through 6am
Sunday, though minor flooding will continue through Sun and Mon.

With the cool sfc temps from the CAD and near isothermal profile
aloft hovering near freezing through 600mb, initial round of
heavy precip may fall as sleet or snow mainly over higher
elevations of northeast GA this afternoon and evening. As warm
conveyer belt increases tonight, warm nose aloft warms to +2-4C
while sfc temps drop to or just below freezing. While GFS and EC
guidance, which handle CAD events poorly compared with hires CAMs,
were a little warmer, have carefully chosen sfc temp and dewpoint
guidance weighted toward CAMs and MDL National Blend of Models,
which has high weight of CAMs in first 24 hours of forecast.
Statistical and bias-corrected forecasts were much too warm and
handle rare, fast-changing events like this poorly and were not
used. Based on these sfc temps, p-types and snow/ice accumulations
were derived from top-down methodology and local studies, which were
then compared against and nudged by WPC Winter Weather Desk guidance
for a sanity check and better inter-WFO consistency. Results of
these forecasts used to drive winter storm warning and advisory
timing and areas. Appreciate coordination from WPC and surrounding
WFOs.

Feel greatest winter impact will be ice accumulation after
midnight tonight through mid-morning Sunday. This could occur in
both the higher elevations and in lower elevation areas affected by
the CAD over northeast GA. With such impressive vertical motion and
high QPF, if sfc temperatures go below forecast values (which is as
mentioned above, already weighted toward cooler CAM guidance), both
ice and snow accumulations could go significantly higher than
forecast. Likewise, if temps go a couple degrees warmer than
forecast, will mainly see a heavy rain event with limited winter
weather impacts. If there is one bright spot, its that many
businesses and most schools will be off during this event.

As the first wave moves out Sunday, another weak wave moves in
behind it so have kept clouds and some precip in, though sfc
temps should warm above freezing Sunday afternoon in the wake of
the first wave, so threat for accumulating precip ends Sunday
afternoon.

Will also have some windy conditions this afternoon and tonight as
pressure gradient between strong sfc low over south GA and CAD
wedge. This strong sfc low and winds are a little atypical for
winter CAD events here, so a little more concerned about the overall
strength and potential of this system. Bust potential is high on
both the low and high side!

SNELSON

.LONG TERM /Sunday Night through Friday/...
No changes made to the general trends through the extended forecast
period. Period starts on the backside of the exiting storm system.
Extent and duration of any wrap-around precipitation still a bit
uncertain, however with temperatures expected to remain at or a bit
above freezing across all but the highest elevations, minimal
additional accumulations are expected Sunday night through Monday
evening. Bit of a break expected Tuesday/Wednesday before the next
system approaches Thursday and sweeps through Friday into Saturday.
Enough instability and forcing for at least a slight chance of
thunder Friday.

.AVIATION...
12Z Update...
Ceilings will continue to lower to IFR across the taf sites and
persist through the period. Winds will remain easterly and
by this afternoon expect close to 15 kts gusting 25 kts and then
even higher for tonight...with up to 20 kts gusting 30 kts.
Precip through the  period looks to be rain except a possible
transition to FZRA over the KATL to KAHN area after 06z Sunday to
near 15z Sunday...with still some uncertainty.

//ATL Confidence...12Z Update...
Medium to high on all elements except
Low on late period potential for FZRA at northern sites.
