More Storms Could Create Flooding In Chicago Area
CHICAGO (CBS) -- Thunderstorms moving through the Chicago area have prompting a flash flood watch for all of northeastern Illinois, and a flash flood warning for a smaller part of the Chicago area.
Storms that rolled through Thursday night and Friday morning brought up to 3 inches of rain to some northern suburbs, with about an inch and a half falling in Chicago. Thunderstorms hitting the Chicago area Friday afternoon could bring another 1 to 3 inches on top of what fell Thursday night and Friday morning.
Due to all the rain, the National Weather Service has issued a flash flood watch from 7 p.m. Friday until 7 a.m. Saturday for Cook, Will, DuPage, Lake, McHenry, Kane, Grundy, Kendall, DeKalb, LaSall, Lee, Ogle, Boone, and Winnebago counties.
In addition, a flash flood warning has been issued for southeastern Cook County, northern Will County, east central Kendall County, and northern Lake County in northwestern Indiana until 11:30 p.m.
According to the National Weather Service, rainfall amounts of nearly two inches an hour have been reported in some areas.

While the storms moving through Friday afternoon and evening have not generated any severe thunderstorm warnings as of 6 p.m., they did prompt a brief tornado warning for parts of Cook and Will counties, but that has since expired.
More heavy rain is possible Friday night and early Saturday before skies clear after dawn Saturday. Some lingering showers will continue early Saturday, but the most organized storm activity probably will have moved through by late Friday night.
