Information updated at 4:00 AM CDT on 4/7/2023

  • Severe thunderstorms tracked east-northeast through northern Illinois during the morning and early afternoon of Tuesday, April 4th, producing widespread large hail and locally damaging winds.
  • The storms that produced the largest hail tracked from basically the Quad Cities through the southwest and then north Chicago suburbs, with numerous instances of golf ball size hail or larger reported across this corridor. The largest reported hailstone was 3 inches in diameter (slightly larger than baseball) in Oswego, which was the largest hail reported in the NWS Chicago County Warning Area since April 7, 2020.
  • These morning storms also produced locally severe winds, primarily from the Quad Cities through Lee County in north central Illinois, but also across a portion of central Cook County as well.
  • After these storms exited the area, isolated storms redeveloped in the evening hours. While these directly did not produce any documented severe weather, damaging non-thunderstorm winds (measured to be 60+ mph) occurred behind a northward surging front ahead of these storms and caused damage in Mendota in LaSalle County and Round Lake Beach in Lake County (IL), among other locations. 
  • One more round of strong to severe thunderstorms developed during the morning hours of Wednesday, April 5th. These storms ended up producing sporadic wind damage as they marched across northern Illinois and northwest Indiana.
