What forecasters said that day

NWS Lincoln, IL wrote its last area forecast discussion before this severe thunderstorm warning went out at Oct 24, 3:44 PM CDT, 2 hours 44 minutes earlier.

Area forecast discussion, Oct 24, 3:44 PM CDT, 2 hours 44 minutes before
Area Forecast Discussion
National Weather Service Lincoln IL
344 PM CDT Sun Oct 24 2021

.SYNOPSIS...
Issued at 344 PM CDT Sun Oct 24 2021

Multiple severe weather hazards exist across central Illinois late
this afternoon and evening...including the potential for flash
flooding. Be sure to review your weather safety plan and stay
situationally aware.

&&

.SHORT TERM...(This evening through Monday)
ISSUED AT 344 PM CDT Sun Oct 24 2021

20z/3pm surface analysis shows a 997mb low over northwest Missouri
with a warm front extending eastward along a Kirksville...to
Taylorville...to Terre Haute line. Temperatures have surged well
into the 70s south of the boundary, while readings hover in the
50s to the north. As expected, a couple bands of convection are
developing within the warm sector of the system. The first extends
from near Macomb southwestward to Columbia, Missouri...while the
second is further west immediately along an advancing cold front
across western Missouri. Given high degree of wind shear in the
environment, all severe hazards will be possible as the storms
track through the area late this afternoon and evening. Damaging
wind gusts and large hail will be the primary threats: however, a
couple embedded tornadoes may develop along the lines...especially
this evening for locations along/south of I-72. Based on regional
radar trends and latest HRRR, it appears the western line of
convection will push across the I-57 corridor by around
midnight...then into Indiana shortly afterwards. As the surface
low lifts into north-central Illinois late tonight, showers will
wrap back into the area and will linger through at least midday
Monday before gradually tapering off and coming to an end from
west to east during the afternoon. Main weather story on Monday
will be the windy and colder conditions. After a brief warm-up
this evening when the warm front lifts north of I-72, temps will
crash late tonight and will remain in the lower to middle 50s on
Monday. In addition, strong NW winds gusting 30-40mph will make it
feel even chillier.

&&

.LONG TERM...(Monday night through Sunday)
ISSUED AT 344 PM CDT Sun Oct 24 2021

High pressure will build into the region Monday night, resulting
in clearing skies and diminishing winds. With low temperatures
expected to drop into the middle 30s, think patchy frost is a
good bet across the Illinois River Valley. Further east, think
temps will remain a bit too warm in the upper 30s and lower
40s...and winds will remain too strong for frost formation. After
a chilly start to the day, ample sunshine will warm readings into
the upper 50s and lower 60s.

After that, another frontal boundary will swing into the Midwest
by the middle of the week. With the associated upper low cutting
off from the main flow, this system will be slow to arrive and
slow to depart. As a result, have delayed PoPs on Wednesday...and
these may need to be further reduced or even removed entirely if
trends continue. Have then gone with high PoPs Wednesday night
through Friday before the system finally departs by next weekend.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 111 PM CDT Sun Oct 24 2021

IFR ceilings will prevail across central Illinois for the next
couple of hours before a warm front pushes northward and improves
ceilings later this afternoon/evening. Based on current placement
of front and 12z NAM/HRRR data, it appears will rise to VFR at
KSPI by 20z...then further NE to KDEC/KCMI by around 22z. KPIA
will likely remain IFR/MVFR for the entire 18z TAF period. Radar
imagery shows a relative lull in precip: however, a line of
convection is beginning to take shape across western Missouri.
These storms will continue to develop and track E/NE into central
Illinois late this afternoon and evening. Will continue to feature
VCTS at the terminals for now, but will likely upgrade to
prevailing once radar trends are more apparent and exact timing
becomes certain. One or two lines of storms will push through the
area this evening before a cold front sweeps the convection into
Indiana after midnight. Once the front passes, winds will veer to
NW and MVFR ceilings will spill back across all of central
Illinois overnight into Monday morning. Winds will also become
strong/gusty behind the front, with numeric guidance and forecast
soundings suggesting gusts in excess of 30kt on Monday.
