Surveyors from the National Weather Service are fanning out across portions of three northern Illinois counties to review storm damage after funnel clouds and possible tornadoes were reported in the area.
The agency says it'll head to eastern Lee County, far southern DeKalb County and Kendall County on Thursday to examine damage from Wednesday evening's storm. The teams will be focusing on a corridor from Paw Paw and Shabonna east to Plano and Yorkville.
The mammoth storm wasn't as severe as forecasters predicted and caused minor damage. But it did pelt the region with golf ball-sized hail and high winds that reached 70 mph.
ComEd officials say about 9,200 customers were still without power on Thursday morning while another 1,600 Ameren customers were also in the dark.
