This was the 5th warmest winter on record in Illinois. The average temperature across the state this winter came in at 34 degrees, which is nearly 5 degrees above normal. State Climatologist Jim Angel says we’ve been see a lot of mild winters lately.
Angel says forecasters weren’t initially sure how this winter would play out since a La Nina Effect was emerging. That could have led to a colder winter for Illinois but the effect weakened and stalled out in the fall.
