This year's fall has been the warmest on record in Illinois since 1931.
Climatologist Jim Angel says the statewide average temperature for September through November was 59.4 degrees, or 5 degrees above normal. The same three months of 1931 were slightly warmer at 59.8 degrees.
November of this year was the fifth warmest November on record. The statewide average temperature in November was 47.4 degrees, nearly 5 degrees above normal. The warmest November in Illinois was in 2001 when the average was 49.9 degrees.
Most of the state had below-normal precipitation in November. The driest spots were in southern and western Illinois.
Angel works for the Illinois State Water Survey at the University of Illinois at Urbana-Champaign, a division of the Prairie Research Institute.
