Trained weather observers reported funnel clouds over parts of DuPage and Cook counties Wednesday afternoon as part of a severe weather outbreak that triggered tornado warnings in several other communities.
According to the National Weather Service, a funnel cloud was reported during a thunderstorm that affected northeast DuPage County. This cloud was spotted around 3:35 p.m., officials said.
The cell that spawned the funnel led to a tornado warning, which lasted until 4:15 p.m.
In Cook County, a funnel cloud was reported by amateur radio around 4 p.m. The cloud was spotted about two miles north of the intersection of Foster and Illinois-83 in the suburb of Elk Grove Village.
That cell led to a tornado warning for northwest Cook County until 4:30 p.m., officials said.
Both warnings have since expired and no confirmed tornado landfalls have occurred.
A Kane County tornado warning, triggered by a rotation indicated by radar, was cleared to expire at 4 p.m.
More thunderstorms could potentially develop in the region as the atmosphere destabilizes, with warm, moist air helping to fuel storm development. Isolated tornadoes, hail and straight-line winds could potentially become issues in the late afternoon and early evening.
