According to ChicagoWeatherCenter, the total rainfall at O'Hare -- 6.91 inches as of about 6:50 a.m. -- is the largest single-day rainfall since records began in 1871. The highest previous daily total was 6.64 inches on Sept. 12, 2008. And more rain is on the way.
There were rainfall totals as high as 7 inches as the storm moved noisily through the Chicago area after midnight, resulting in flash flood warnings from the National Weather Service and enough flooded roads and highways to make life miserable for passengers headed to or from O'Hare International Airport and make a mess of traffic overnight and into Saturday morning.
The north side got the brunt of the rain, with O'Hare International airport getting 5.53 inches in two hours, according to ChicagoWeathercenter.com. Some other totals of note reported by the Weather Center: 6.41 inches in Glenview, 5.4 inches in Arlington Heights and 5.49 inches in Elk Grove Village.
