...PERIODS OF HEAVY RAINFALL POSSIBLE TONIGHT THROUGH SATURDAY
NIGHT...

A surface front will stall across northern Illinois tonight, and
act as the focus for a period of showers and thunderstorms into
Saturday morning. A strong storm system is then expected to drive
a cold front eastward across the area Saturday night, with
another round of very heavy rainfall possible. Given the
unseasonably high amounts of atmospheric moisture, these showers
and storms will be capable of producing locally heavy rainfall.
Also, due to the fact that these storms will move over the same
areas that recently received heavy rain, increased runoff may
result in significant rises on area streams and rivers.
