What forecasters said that day

The local office's own words before this dense fog advisory 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 dense fog advisory went out at Jan 3, 2:34 PM CST, 4 minutes earlier.

Area forecast discussion, Jan 3, 2:34 PM CST, 4 minutes before
Area Forecast Discussion
National Weather Service Lincoln IL
234 PM CST Sun Jan 3 2021

.SYNOPSIS...
Issued at 232 PM CST Sun Jan 3 2021

Abundant low-level moisture remains in place across the area.
Dense fog is expected to develop again this evening and persist
through much of the morning Monday. High pressure will build into
Central and southeast Illinois through much of the week.
Conditions should remain mostly dry with temperatures near to
slightly above normal.

&&

.SHORT TERM...(This evening through Monday)
ISSUED AT 209 PM CST Sun Jan 3 2021

Surface ridge will drift across the state overnight setting us for
another night of low ceilings and potentially dense fog. With
overnight temperatures mostly in the 20s, some ice depositian on
untreated surfaces, particularly bridges and overpasses will be
likely adding to the hazardous conditions.

Despite short-wave ridging into Illinois on Monday and the surface
ridge sliding east, temperatures above the strong boundary layer
inversion are expected to climb 7-10C at 850mb between 03/12z and
04/12c futher reinforcing the inversion. Clouds will likely linger
again Monday with any breaks short-lived. Have reduced temps
several degrees in areas that received 4"+ snowfall amounts last
night as any solar heating will go into melting the snow and keep
temps from climbing much above freezing.

&&

.LONG TERM...(Monday night through Sunday)
ISSUED AT 232 PM CST Sun Jan 3 2021

A northern stream system should skirt central Illinois on Monday
Night. Models differ with on whether forcing with the wave is
sufficient to squeeze out any precip from the boundary layer. NAM
is the most aggressive, while deterministic ECMWF and GFS keep
chance PoPs to our north. NBM keeps area dry with only the WRF
with QPF. Won't include chance PoPs, but wouldn't be too suprised
to see a few flurries north of I-74.

Energy approaching the Midwest toward midweek de-phases as it
splits around Illinois. Southern stream wave digs into the lower
Mississippi Valley while northern stream races east into Ontario.
Forecast area should be on the northern fringe Wednesday and
Wednesday Night of the southern cutoff and some chance PoPs will
be introduced across west central Illinois. The bulk of the area
should remain dry.

Illinois remains mostly between jets through the rest of the week
with mostly dry conditions and temperatures near to slightly above
normal into the weekend.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1133 AM CST Sun Jan 3 2021

LIFR ceilings are expected to persist through the period, as
excessive moisture continues to flood central Illinois. A small
break in cloud coverage is occurring midday across southern
Illinois, with SPI going BKN this afternoon...however still in IFR
category. As evening arrives, expecting ceilings to fill again to
OVC, along with the return of FG in the overnight. Below freezing
temps will create FZFG around the region tonight, with the
possibility of another Dense Fog Advisory needed tonight as
visby's drop below 1/2SM. Visby's are expected to increase Monday,
however it might take some time through the morning.
