The episode as NWS ILX wrote it up.
A winter storm brought a period of freezing rain to portions of central Illinois on December 1st. The freezing rain broke out during the mid morning hours and tapered off by late afternoon. The freezing rain deposited widespread quarter inch to three tenths of an inch of ice along and north of a line from Rushville to Bloomington. Lesser amounts of ice accumulation occurred south of this line. The storm caused numerous power outages and minor vehicular accidents, but no major damage or injuries.
