Monthly Temperature and Precipitation Departures for 2014 for Illinois

Here are the monthly temperature and precipitation departures for 2014. September joins January, February, March, and July as much cooler than average months. For precipitation, we noted last month that we were regularly alternating between wetter- and drier-than-average months in 2014. That changed in September with two months in a row of wetter-than-average conditions.
