Scattered showers and thunderstorms popped up all over the Chicago area Tuesday evening.
The heavy rains caused wide spread flooding – including portions of the Eisenhower Expressway, which was shut down near 25th Street.
Reports of funnel clouds in Hinsdale and Lombard have promted local
officials to sound sirens despite the fact the National Weather Service
has not issued a Tornado Warning as of 6:40PM.

Heavy rains have moved into southern Cook County – veteran weather
observer Frank Wachowski reports 1.20 inches of rain at Midway Airport
in 20 minutes – a rate of 3.60 inches an hour.
Weak circulations aloft (funnel clouds) have developed and been
sighted in Du Page and Cook Counties – particularly near Oak Brook,
Western Springs, and Hinsdale. These funnel clouds last a few minutes
before dissipating and rarely touch the ground under these conditions –
if a touchdown does occur minimal – if any damage occurs.
A strong thunderstorm passed over Park Ridge and Summit in Cook County. A
downpour of .94 inch in 20 minutes (a rate of 2,80 inches/hour) was
reported in Park Ridge, while water was observed above curb level in
parts of Summit.
The Illinois State Police report the Eisenhower Expressway is shutdown in both directions at 25th Street due to flooding.
Latest national Weather Service Doppler radar indicates the large
thunderstorm cell has weakened slightly and moved south through eastern
Will County into northeastern Kankakee County.
The storm should continue to slowly
weaken as it moves farther south into eastern Kankakee County.
