High Resolution Precipitation Maps for Illinois
Dr. Jim Angel, State Climatologist
High resolution precipitation maps based on NWS radar-estimated precipitation, adjusted using available rain gauge data. This results in 4 km (or 2.5 mile) resolution maps of precipitation. These are typically updated by 4:15 pm each day for conditions through this morning. It takes a lot of behind-the-scenes processing to make this happen. Finally, there were some changes made in the links on May 2, 2018.
