...MULTIPLE ROUNDS OF HEAVY RAIN POSSIBLE TONIGHT AND AGAIN
SUNDAY NIGHT...

Multiple heavy rain producing thunderstorms may train over the
same areas of northern Illinois tonight and again on Sunday night.
Because of this, localized areas of northern Illinois could
experience rainfall amounts in excess of 2 to 3 inches tonight,
with additional heavy rainfall possible Sunday night. Because of
this, there will be an increased threat of flash flooding,
particularly if the heaviest rain producing storms train over the
urbanized areas of Chicago and Rockford. This heavy rain will
also likely result in significant rises and possible flooding on
area streams and rivers. Stay tuned to the latest forecast
information.
