Slow-moving system brings soaking rains

|
Flooding downpours hit sections of the Chicago area with clusters of
slow-moving thunderstorms late Tuesday. Radar scans indicated cloud tops
over 40,000-feet tall.

   The weather system responsible was the same one that flooded sections
of Florida with more two feet of rain last week. Its northward jog
across Illinois generated 10.50 inches of rain in Downstate
Edwardsville, northeast of St. Louis, on Monday.

  By late Tuesday, rainfall totals in the Chicago area had passed 2.50
inches at Joliet with more than 2 inches measured in Plainfield and more
than 1 inch at Oak Brook and Midway Airport.

Wet spring at Midway

  The recent downpours have helped push the rainfall tally since March 1
(the start of meteorological spring) to more than 16 inches at the
Southwest Side site, wettest of any such period on record since 1928.
