The National Weather Service relies on volunteer weather observers to provide real-time weather data. That data helps meteorologists make more accurate predictions. Tim Halbach is the warning coordination meteorologist for NWS-Milwaukee. He says one weather observer in one town isn't enough because precipitation amounts can vary greatly between miles alone. NWS and Mid-West Farm Report are encouraging you to sign up to be a weather observer!
