Where rainfall reports come from

Reports can come in various ways, but the most common is through the ASOS (Automated Surface Observing Systems), COOP (Cooperative Observer Program) observers and the CoCoRaHS (Community Collaborative Rain, Hail, and Snow Network).

CoCoRaHS is a great way to put your town on the map in the weather community. There are plenty of reports that come from metro areas, but it helps to piece the weather story together when we have a wide variety of reports coming from rural areas as well.

Counties with 1 or less report with last night’s storms include Adams, Audubon, Adair, Calhoun, Clarion, Decatur, Franklin, Greene, Grundy, Hamilton, Hardin, Humboldt, Jasper, Lucas, Marshall, Monroe, Pocahontas, Poweshiek, Ringgold, Taylor, Union, and Wapello.
