The statewide average temperature for November was 43.4 degrees, which is 1.6 degrees above normal. This ranks as the 26th warmest November on record, according to State Climatologist Jim Angel of the Illinois State Water Survey (http://www.isws.illinois.edu).

The past decade has been well represented in the list of warm Novembers. Their rank and year include: #1 (2001), #5 (2009), #10 (2004), #14 (2003), #16 (2005), and #17 (2006).

The highest temperature for the month was reported at Cairo with 82 degrees on November 13. The lowest temperature for the month was reported at Mt. Carroll with 12 degrees on November 26.

The statewide average precipitation for November was 3.2 inches, only 0.1 inches below normal. November was exceptionally dry until the long Thanksgiving weekend arrived. Rains from that period were widespread and heaviest in the southern half of the state. Amounts of 3 to 6 inches were common in southern Illinois. Mt. Carmel received 7.15 inches, the largest monthly total in the state.

As a result of the rain, Illinois was removed from drought status in the U.S. Drought Monitor. A few areas in southeastern and northeastern Illinois are still considered “abnormally dry” based on existing rainfall deficits in the 90-day time frame.

The Illinois State Water Survey at the University of Illinois at Urbana-Champaign, a division of the Institute of Natural Resource Sustainability, is the primary agency in Illinois concerned with water and atmospheric resources.
