Pause between major storms only 30 hours

Someone once remarked that meteorologists have a technical term to describe a dry day
following two rainy days. It's called Monday -- and that describes the
Saturday-Sunday-Monday situation.
The weekend deluge put down 2 to 4 inches of rain (isolated locations recorded even
more) that sent rivers and streams out of their banks. It takes a few days for water levels
to recede because the terrain is so flat, and the larger rivers (such as the Fox and Des
Plaines) drain so slowly.
HERE WE GO AGAIN
Another powerful storm system is blasting toward the area. Energized by a jet stream
whose core winds will attain speeds of 160 m.p.h. at 30,000 feet in north and central
Illinois on Tuesday afternoon, the approaching rain producer is a system to be watched.
Rain and thunderstorms arrive by midnight Monday -- only 30 hours after the flooding
rains ended Sunday afternoon. In addition to flood-exacerbating rain, severe storms are
possible Tuesday. Then the bottom drops out: Arctic air sends temperatures tumbling 40
degrees by midweek.
