Weather Watchers (CoCoRaHS) in Illinois

Dr. Jim Angel, State Climatologist

The Community Collaborative Rain, Hail, and Snow Network (CoCoRaHS) in Illinois provides high-density, high-quality weather observations on a daily basis from their website. Click on Illinois on the US map to get Illinois reports.

This is an excellent way to monitor heavy rains, major snow storms, and hail events. Detailed maps are available here and detailed tables are available here. You have the option of selecting dates, counties, and weather variables.

Volunteers Always Needed

Volunteers are always needed to participate as weather watchers in the CoCoRaHS network in Illinois. Anyone can participate. The only requirements are an enthusiasm for watching and reporting weather conditions, and a desire to learn more about how the weather can affect and impact our lives.

CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds, working together to measure and map precipitation (rain, hail and snow). By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web site, the aim is to provide the highest quality data for natural resource, education and research applications.

CoCoRaHS in Illinois is sponsored by the Illinois State Water Survey, the National Weather Service, the University of Illinois Extension Service.

To learn more about CoCoRaHS and what is needed to participate, visit the CoCoRaHS web site at http://www.cocorahs.org. Click on Illinois on the map to see more about CoCoRaHS in Illinois.
