Numerous severe thunderstorms developed over the region late Tuesday afternoon and persisted into the evening, producing widespread large hail. No injuries or fatalities in the NWS Quad Cities CWA with these storms.
The largest hail, which was to dangerous levels if being caught outside in it, was 2.75" in diameter (baseball size), was reported near West Branch in Johnson County, IA, and near Davis and Lena in Stephenson County, IL.
In just the one hour span from 6:30 to 7:30 P.M., 51 reports of severe hail were received by the NWS Quad Cities office.
There were 10 total reports of significant hail (2+" in diameter) in the NWS Quad Cities County Warning Area (DVN). In our period of record, that is the third most significant hail reports with an event, behind April 7, 2020 (14) and April 4, 2023 (12).
The total number of significant hail reports was greater than the annual average we receive (6)!
Many storms had rotation, and a few of them were persistent and in a favorable environment to warrant Tornado Warnings. One of these storms produced three EF1 tornadoes near Donnellson, IA in Lee County as documented by an NWS Damage Survey Team. Damage was mainly to outbuildings and trees. There were the earliest tornadoes in a calendar year in Lee County, IA since 1967.
Other noteworthy storms that prompted Tornado Warnings included:
A storm near Kewanee, IL had reports of visible rotation as it passed near the city, although no tornado or damage was reported.
The NWS Central Illinois office conducted a storm damage survey near the far southern Putnam County border as part of a storm that moved across Stark and Marshall Counties in IL. The tornado they confirmed was south of the county border by just one mile.
The threat of severe weather had been mentioned for several days, and watches were in effect in advance too. The local office issued 39 total SVR and TOR Warnings, which was one of the higher totals our office has issued in a calendar day, speaking to the event's widespread nature of supercell storms (i.e. rotating storms that can support large hail growth).
This was part of a larger regional outbreak, including hail to 5+ inches and damaging tornadoes with multiple fatalities in the NWS Chicago area, and some tornadoes in the NWS Central Illinois area.
