The PRISM Group (http://prism.oregonstate.edu) is in the process of completing the gridded 1981-2010 Normals.  These Normals are calculated every ten years and span the previous 30-year period.  For the first time, there were CoCoRaHS stations with histories long enough that they could be used in the process of creating the PRISM grids. 

This is a major accomplishment for the CoCoRaHS network and I'm proud to report that 73 stations in Wyoming were able to be used in the generation of Normals for at least one of the months of the year. 16 stations had data complete enough to be used for all 12 months and the Annual total. To be considered adequately complete, the station had to have 85% of the observations for a given month for five or more years.
