Chicago Tribune staff report
More than 10 inches of rain fell in Dixon and west of Mendota just outside the Chicago area in the last 24 hours, according to National Weather Service radar estimates.
“There was a super cell that basically sat over those areas for several hours, it just sat and rained for hours and hours,” National Weather Service Meteorologist Ben Deubelbeiss said.
Measured totals, which may differ from radar estimates, are expected later today as emergency managers across the towns and counties finish early assessments, Deubelbeiss said.
The rain during the same period was more subdued in the city and suburbs but more is possible Thursday evening overnight into Friday, according to the National Weather Service.
Over about the last 24 hours, St. Charles registered 2.69 inches of rain while both O’Hare and Aurora came in at just under three-quarters of an inch, Deubelbeiss said. About two inches fell at DuPage Airport in West Chicago.
The storms also packed heavy winds: a gust of 77 m.p.h. was recorded about 6 miles south of Aurora and 60 m.p.h. in Montgomery, WGN Meteorologist Tom Skilling reported.
Rain is possible this morning in the far west suburbs but Cook County should remain dry until overnight Thursday into Friday, Deubelbeiss said.
“There’s a ‘stationary front’ that’s draped just to our south,” he said. “It’s just kind of sitting there from roughly Moline to just south of Kankakee.”
“There’s a small chance (for precipitation) this afternoon, better chances tonight,” he said.
The rain overnight didn’t seem to cause any public transportation problems – both the CTA and Metra are reporting normal service this morning.
Temperatures today are expected to be cool near the lake – upper 60s, 70 tops, Deubelbeiss said. But further away from the city, the temperatures could reach 80 degrees.
