Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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, 8.9 hours before the alert went out and 29 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.

- Two periods of severe weather are expected through tonight. Of those, the first one (2-10 pm) would be most likely to produce all severe weather hazards, primarily west of I-55. The second one, after midnight, will mainly see a localized damaging wind threat.

Area Forecast Discussion National Weather Service Lincoln IL 137 PM CDT Fri Apr 3 2026 .KEY MESSAGES... - Two periods of severe weather are expected through tonight. Of those, the first one (2-10 pm) would be most likely to produce all severe weather hazards, primarily west of I-55. The second one, after midnight, will mainly see a localized damaging wind threat. - A trend for cooler weather is on tap for the second half of the weekend, into Tuesday. There is concern for a hard freeze in parts of central Illinois Monday night, mainly focused on areas near and north of I-74. && .DISCUSSION... Issued at 137 PM CDT Fri Apr 3 2026 Through Saturday: A warm front was located roughly along I-72/US-36 early this afternoon, with temperatures south of it in the lower 70s and dew points in the mid 60s. Recent satellite imagery shows this particular region, while still having a fair amount of clouds, has had some breaks that have helped boost mixed layer CAPE's to around 1000 J/kg. Noontime run of the WoFS model suggests the boundary lifting about as far north as Peoria by mid afternoon. WoFS output, as well as recent runs of the HRRR and the 12z RRFS, are all focusing on convective initiation in the 2-3 pm time frame. This seems on track, as visible satellite is showing some towering cumulus centered along I-72, and some showers have been popping recently in east central Illinois. While severe weather is not a slam dunk this afternoon and evening, there are enough components that all hazards remain in play. However, most of this focus will be west of I-55, and especially toward the Illinois River valley. The first batch of storms will likely be out of our forecast area by late evening, but the line of storms associated with the cold front won't be too far behind. Main focus for that band will be in the midnight to 5 am time frame, with the main concern being with localized 50-60 mph wind gusts. After that, rain tapers from west to east on Saturday as the front pushes into Indiana by midday. Sunday through Tuesday: Much of this period will be fairly tranquil, as high pressure settles into the mid Mississippi Valley. Main concern in this time frame is with the cooler temperatures, and potential for a hard freeze. Latest LREF has about a 40% chance of a hard freeze (lows 28F or colder) Monday night, roughly along and north of I-74. Wednesday through Friday: A significant warming trend takes place, as the upper flow becomes more zonal, and high temperatures return to the 60s and 70s. Main feature of note will be a strong shortwave tracking across the northern states Wednesday-Thursday, with a trailing cold front arriving around Thursday. As it starts to parallel the upper flow, an extended chance of rain begins to set up. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... Issued at 1240 PM CDT Fri Apr 3 2026 A northward lifting warm front will bring southerly winds across the board through this afternoon and evening. Sustained wind speeds will be around 10 kts with occasional gusts near 20 kts through late tonight. Scattered showers and thunderstorms are possible in the vicinity of the warm front, as well as within the warm sector. This threat exists primarily between 22z-03z at all terminals, though confidence and coverage remain low enough to cover with a PROB30 group for the time being. Later this evening, a higher confidence chance for widespread showers and thunderstorms exists, and will spread from west to east along a cold front. We covered this threat with a predominant TSRA mention, mainly between 05z-12z. Behind the leading line of thunderstorms, a trailing stratiform rain is likely through mid- Saturday morning before clouds gradually begin to lift and break by the end of this TAF period. && .ILX WATCHES/WARNINGS/ADVISORIES...
