What happened

The episode as NWS LSX wrote it up.

An ice storm struck parts of west central Illinois from the night of January 29 through the afternoon of January 30. With the temperature in the upper 20s to near 30, falling rain quickly froze on exposed surfaces such as trees and power lines. The hardest hit area was northwest Adams County. Local officials stated that they had not seen "anything like this in 50 years". Power outages were common with some residents without electricity for 2 to 3 days. A woman in Mendon suffered minor injuries when she was struck in the head by a falling tree branch.
