The radar

The Evansville,IN radar (KVWX), 74 km from the middle of the area, began a volume at 20:59 UTC, the scan nearest the moment this went out.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Lincoln, IL (KILX), launched 12:00Z, 9.0 hours before the alert went out and 165 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Apr 10, 1:36 PM CDT, 2 hours 23 minutes earlier. Its key messages:

Scattered showers and storms will affect parts of central and southeast IL this afternoon and evening. A few strong storms are possible with gusty winds and small hail.
Cold air will overspread the area Friday night. There is a potential for sub-freezing lows, primarily east of I-57.

Area Forecast Discussion
National Weather Service Lincoln IL
136 PM CDT Thu Apr 10 2025

.KEY MESSAGES...

- Scattered showers and storms will affect parts of central and
  southeast IL this afternoon and evening. A few strong storms are
  possible with gusty winds and small hail.

- Cold air will overspread the area Friday night. There is a
  potential for sub-freezing lows, primarily east of I-57.

.DISCUSSION...
Issued at 136 PM CDT Thu Apr 10 2025

Latest water vapor imagery showed a series of shortwaves just to
our west and northwest that will track southeast across our area
through this evening. At the surface, a weak/stationary
convergence boundary was analyzed along a Galesburg-Springfield-
Flora line at 18z. Forcing ahead of these waves, and along and
south of the boundary will be a focus for scattered convection
until around 03z. Thermodynamic fields support a few strong
storms, primarily due to steep mid level lapse rates and a
pronounced near surface dry layer (inverted-v soundings below 850
mb). This would promote a few stronger downdrafts and small hail,
possibly up to quarter size. Deep layer shear is unimpressive,
generally under 25 kt, so we don't expect much organization to
these storms and mainly a pulse strong/severe storm.

Next item of interest is a chunk of seasonably cool air sliding
into the Midwest behind this system. 850 mb temps drop to -3C
early Saturday morning, concurrent with surface ridging sliding
over our eastern CWA. Near ideal radiational cooling in place,
especially near and east of I-57 where blended guidance shows lows
30-32F. Cooler end of guidance has upper 20s lows, so sensitive
early season vegetation could again be at risk, and will be
monitoring this period for a potential Freeze Warning.

A surge of warm advection will overspread the region this weekend
as return flow sets up on the back side of the ridge, with gusty
south winds pushing highs into the lower on Sunday west of I-55.
A few showers could occur as the low level jet veers into the area
Sunday morning, but this looks brief and focused farther to the
north.

Global ensembles continue to advertise a closed 500 mb low
crossing the far upper Midwest late this weekend, and a sub 1000
mb surface low tracking through the northern Great Lakes Monday.
This will keep windy conditions going Monday, along with our next
chance of showers and storms. 12z guidance shows a progressive
frontal passage, clearing central IL by mid morning. If these
trends hold any strong/severe storms would be more likely to our
east, in line with SPC's Day 5 outlook. Beyond this system,
cooler and dry air looks to overspread the area into midweek.

.AVIATION...  (For the 18z TAFs through 18z Friday Afternoon)
Issued at 1210 PM CDT Thu Apr 10 2025

Scattered showers/storms are forecast to develop later this
afternoon along a weak convergence boundary, particularly from
KSPI/KDEC to the south. Included a PROB30 to account for this,
with terminals farther north staying dry. This activity will
diminish by mid evening as a backdoor cold front works in from the
northeast. This will turn winds solidly northeast across the
entire area at 10-15 kt. After 06z, lake enhanced moisture on the
northeast flow should bring a layer of MVFR clouds in from the
northeast, with the back edge of this cloud deck eventually
pushing south of the area through late morning.
