A large complex of showers and thunderstorms continues to slowly move east across northern Illinois early this morning. While the overnight storms were rather loud, they were also fairly tame with little or no wind or hail reported over most of the Chicago area.
The latest radar trends would suggest that the majority of the rain should move out between 6AM and 7AM.
The most serious problem has been heavy rain and flooding that has been largely confined to some south and southwest suburbs. A Flash Flood Warning continues for portions of Kendall, Grundy, DeKalb and LaSalle Counties. http://weblogs.wgntv.com/chicago-weather/severe-weather/2010/06/flash-flood-warning-until-845a.html
Once the rain ends in the next hour or so, dry weather will take over for much of the rest of the day with only a few scattered storms expected this afternoon. A Flash Flood Watch remains in effect until Noon for most of the Chicago area, but this watch may be canceled early.
