Doppler radar does a pretty good job of telling us when precipitation is falling, but it can only roughly estimate how much has fallen.
There is a tremendous need for weather observers across the nation. Forecasters and climatologists alike need good reports of rainfall and snowfall to help verify forecasts, predict floods, issue storm warnings and study climate. Any interested person is able to help by joining the Community Collaborative Rain, Hail and Snow (CoCoRaHS) Network.
In March, CoCoRaHS is again running its annual March Madness competition in which states compete for the most new weather observers. North Dakota won the competition in 2010, 2012 and 2015. All you need to become a weather observer is an interest in weather a good rain gauge, and a few minutes a day. Click here to volunteer for the CoCoRaHS Network.
