A slow-moving frontal boundary brought very heavy rainfall to central Illinois from Monday, February 19th through Tuesday, February 20th.  Many locations east of I-55 and north of I-70 picked up 3 to 5 inches of rain...with locally higher amounts in excess of 6 inches.  The heavy rain occurring on top of the frozen ground led to significant run-off and widespread flooding along area creeks and streams.  Several roads had water flowing across them during the evening of February 20th, particularly across portions of Champaign and Vermilion counties.  In addition, the Vermilion River exceeded its banks...forcing the evacuation of 25 homes on the west side of Danville.  High water continued to impact eastern Champaign County into Vermilion County into Friday, February 23rd.
