Illinois Water & Climate Summary
The Illinois Water and Climate Summary (IWCS) is a monthly publication issued by the WARM Program of ISWS on water and atmospheric data collected by several operational data networks during the prior month. The summaries report on current and trending water and weather conditions in Illinois and their impacts on other water resources of the state. Full descriptions of the structure of data collections for each data set are available for weather and climate information, soil moisture information, surface water information, and groundwater information. Additionally, there is information on current long-term regional precipitation networks reported each month, as well as an archive of old summaries.
