Last month was the 10th wettest October on record in Illinois. October was one for the record books, with statewide average rainfall coming in at nearly 5 inches says State Climatologist Jim Angel.
The average temperature last month was 57.7 degrees, that about 3 degrees above normal and makes October 2017 the 21st warmest on record. Angel says many areas of the state dipped below freezing for the first time this fall.
