Chicago Weather: Thunder Through Midnight

CHICAGO (CBS) -- Shower and storm chances stay with us through midnight.

The first round of storms plowed through the city of Chicago as of just after 6 p.m. Meanwhile, storm spotters saw what might be a rotating wall cloud just to the north and northwest of Morris.

Quarter-inch hail was also reported.

A severe thunderstorm warning was issued earlier for LaSalle County. No watches or warnings were in effect in the immediate Chicago area as of 6 p.m., but some remained in effect for Central Illinois.

The National Weather Service warned that several areas of storms would persist through 9:30 p.m., particularly along and south of Interstate 80 and into Northwest Indiana.

Once the cold front passes, the storm threat ends and winds become west-northwest. This wind flow will pull cooler air into the Chicago area.

As the low pressure center lingers across the Great Lakes tomorrow, cool winds and passing showers hang around all day Wednesday.

The low for Tuesday night is 51, the high for Wednesday 56.
