A slow-approaching cold front will allow extended warmth and humidity punctuated by
frequent showers and thunderstorms over the same areas recently hit by copious rains
and flooding. There will be a risk of severe storms, but renewed flooding could be the
greatest concern as heavy downpours from some of the stronger storms may leave
many locations across southern Wisconsin and northern Illinois with rainfall totals in
excess of 2 inches before rains end with an expected cold frontal passage Tuesday.
As the southern edge of a cooler, less humid Canadian high-pressure region pushes
into the Midwest, the band of heavy rains should drift into parts of Missouri, Oklahoma,
Arkansas and Tennessee Wednesday and Thursday. Humid southerly flow and more
thunderstorms return to the Chicago area later Friday and Saturday.
