You might have a different source (that maybe the DL meteorologists used as well!), but I didn't see anything like that in the NWS ones or discussions I was monitoring. (Yes I am a weather geek.)

Here are relevant parts of the 4 PM (yesterday) discussion. By then they were saying travel is not recommended for today across the region. They were already noting the upward trend in freezing rain forecast in the 4 AM (yesterday) one:

...Afternoon Area Forecast Discussion...

.SHORT TERM...
Issued at 413 PM EST Thu Jan 9 2025

Key Messages:

- A Winter Storm Warning has been issued across all of north
Georgia, Athens, the Atlanta metro, and points eastward
generally along and just south of I-20.

- In the metro of Atlanta and east into Athens and the Piedmont,
precipitation may start as snow and then switch to sleet.
Accumulations of 1-2" of sleet/snow will be possible.
Concerning in this area in the upward trend in freezing rain,
with amounts of up to a third of an inch possible. Expect
significant impacts to travel. Ice accumulations may lead to
some tree and powerlines impacts. A switch over to some rain
may be possible in this area later in the evening.

Forecast:

. . . There will be travel impacts across much of the area
tomorrow that will begin during the morning hours. Travel is not
recommended. Stay home if possible. If not, please ensure you
allow plenty of extra time to get to your destination. Take it
slow and leave plenty of distance between you and others.

Broad area of isentropic lift will occur ahead of the low as
moisture is lifted over our cool airmass, bringing an initial
wave of precip into the CWA Friday morning. Precip occurring with
this may take a bit to reach the ground. Dry air is entrenched
near the surface up to about 850mb in the CWA, which will allow us
to wetbulb to below freezing through the entire vertical column.
Initial precip type basically everywhere is expected to be snow.
As the low continues to move east, notable warm "nose" is noted
aloft at between 850mb and 700mb as the LLJ begins to kick in.
This will likely be responsible for our transition from snow to
sleet and freezing rain/just rain from south to north. . . .

As the low moves by, temperatures may rise above freezing for a
brief period, especially as precip comes to an end, but should fall
again later in the night. Impacts should end west to east across the
CWA, with precip moving out by sunrise in eastern Georgia.

Impacts in Metro Atlanta, Athens, and the Piedmont:

- Snow/sleet amounts generally between 1-2". Most of this will
fall during the morning hours and will likely impact
commutes. Ground temperatures as noted on the UGA mesonet are
cold. This should allow snow to quickly begin to stick across
the area, especially if better snowfall rates begin. Expect
travel impacts. This will also be a wet heavy snow.

- Freezing rain amounts of 0.15-0.33". Switchover to sleet and
freezing rain will happen during the afternoon hours and may
persist into the evening. Expect significant travel impacts.
Impacts to trees and powerlines are also anticipated. Please
avoid any unnecessary travel.

- A switchover to rain will be possible towards the evening into
the night for a period. If this remains freezing rain, even
greater ice accumulation may be possible. This would lead to
widespread impacts.
