What forecasters said that day

The local office's own words before this areal flood 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 areal flood warning went out at Dec 30, 2:41 PM CST, 46 minutes earlier.

Area forecast discussion, Dec 30, 2:41 PM CST, 46 minutes before

AREA FORECAST DISCUSSION
National Weather Service Lincoln IL
241 PM CST WED DEC 30 2015

.SHORT TERM...(Tonight)
ISSUED AT 241 PM CST WED DEC 30 2015

As the shortwave pulls off to the northeast, weak high pressure will
continue to build into the region.  However, ample low level
moisture will remain in place through the overnight hours, keeping
the stratus deck over Central Illinois.  Low clouds overnight and
low temperatures in the 20s are expected.  Weak WSW winds will
continue as well.

&&

.LONG TERM...(Thursday through Wednesday)
ISSUED AT 241 PM CST WED DEC 30 2015

Shortwave that triggered light snow over the northern portions of
the region this morning, has moved well off to the northeast. High
pressure will build in tonight and through Thursday. However, lack
of dry air in boundary layers will keep conditions cloudy with
slightly below normal temperatures expected.

Couple of weak upper level troughs expected to move through region
into the weekend. Surface high pressure will be in control over the
area. The result will therefore be dry conditions. Main surface
coldfront to move through Sunday night, as more significant short
wave moves south over Great Lakes. Still dry conditions though, but
with some reinforcing cool air to move in.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
ISSUED AT 1149 AM CST WED DEC 30 2015

MVFR conditions expected to continue through the overnight hours.
Low level moisture trapped in the boundary layer reinforced by
recent rains will keep the stratus firmly in place. Winds are out
of WSW and less than 10kts.

.ILX Watches/Warnings/Advisories...
