What forecasters said that day

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

NWS Lincoln, IL wrote its last area forecast discussion before this winter storm warning went out at Dec 14, 11:12 PM CST, 4 hours 41 minutes earlier.

Area forecast discussion, Dec 14, 11:12 PM CST, 4 hours 41 minutes before
Area Forecast Discussion
National Weather Service Lincoln IL
1112 PM CST Sat Dec 14 2019

.SYNOPSIS...
Issued at 245 PM CST Sat Dec 14 2019

A storm system is expected bring wintry weather to central and
southeast Illinois from Sunday afternoon into the early morning
hours Tuesday. This system will bring a swath of 4 to 7 inches of
snow over the region along Interstate 72, mixed at times with
freezing rain. Lower amounts of snow will occur over the southern
portions of central and in southeast Illinois, with accumulations
of freezing rain. To the north, lighter snowfall amounts will fall.
Hazardous driving conditions can be expected from late Sunday
into Tuesday.

&&

.UPDATE...
Issued at 849 PM CST Sat Dec 14 2019

Clearing line has been slow to make progress, but is now
approaching the I-55 corridor. Not much of a window for clear
skies behind it, as high clouds are already streaming into central
Iowa and Missouri from the central Plains. Temperatures have dipped
below 20 degrees where the clearing has occurred, but still linger
in the 30 degree vicinity over much of the CWA. Updates have been
sent for the cloud and temperature trends tonight.

Regarding Sunday, an early look at the evening mesoscale models
largely shows dry conditions through midday, before the snow
arrives by mid afternoon from Springfield to Flora. Bulk of the
precipitation remains in the evening, with a quick tapering after
midnight. Forecast soundings would suggest the freezing rain
extent currently in the grids may be too far north late Sunday
night, favoring more of the area south of I-70. While adjustments
have been made for the precipitation timing during the day on
Sunday, any changes further out will be held off until the
remainder of the model suite arrives.

&&

.SHORT TERM...(This evening through Sunday)
ISSUED AT 300 PM CST Sat Dec 14 2019

The main concern is the storm that will be affecting the area the
later parts of Sunday and into early Tuesday morning. The models
have come more into agreement on the development of warm advection
pcpn by midday on Sunday, spreading into the region during
afternoon. The heaviest band of snow will this first upper wave
looks to be over the central sections.

&&

.LONG TERM...(Sunday night through Saturday)
ISSUED AT 300 PM CST Sat Dec 14 2019

As time goes on into Sunday night, the first wave moves through
and there looks to be a lull in the pcpn overnight and then
picking up again by midday Monday with the approach of the main
upper level shortwave. The difference today is that the surface
front and associated wave is farther to the south, over west TN
and moving into west central KY, which should keep the heavies
pcpn in the central areas. Overrunning of the front ahead of the
wave does appear to push significant warm air and soundings show
freezing rain to move into the central portions of region mixed
with the snow. The southeast counties will also change over to all
rain. The models are also different today in dragging this pcpn
event later, as the upper wave keeps some deformation pcpn back
later over the region into the overnight hours on Monday night.
Because of this, extended the winter watch watch in the eastern
counties longer, matching up with the WFOs of LSX and IND.

&&

.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 1112 PM CST Sat Dec 14 2019

MVFR cloud deck continues to push southeast across central
Illinois, about to clear KDEC and should pass KCMI within the
first hour of the new TAF set. Main focus then shifts to
deteriorating ceilings and visibilities as snow moves into the
area Sunday afternoon. Impacts near KSPI/KDEC likely to occur as
early as 20-21Z, with a later arrival toward 00Z near KBMI/KPIA.
Once the snow begins, IFR conditions should prevail into Sunday
evening.
