Numerous severe thunderstorms developed across the region late Tuesday afternoon and continued through the evening, producing widespread large hail that in over a dozen places was golf ball size or larger.
The largest hail, to dangerous levels if being caught outside in it, was 2.75" in diameter (baseball size) was near West Branch in Johnson County, IA and near Lena in Stephenson County, IL.
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 two 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, but no tornado or damage was reported.
The NWS Central Illinois office will be surveying near the far southern Putnam County border as part of a storm that moved across Stark and Marshall Counties in IL.
No injuries or fatalities in the NWS Quad Cities CWA with these storms.
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 widespread nature of the 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 in the NWS Chicago area, and some severe weather in the NWS Central Illinois area.
