  • STATE CLIMATE SERIES AT CoCoRAHs   Check-out the "CoCoRaHS State Climates" series page. This series ran as part of the CoCoRaHS Message of the Day during 2011. In putting together our series, we asked climatologists from each of the country's 50 states to write an informational short narrative summarizing their state's climate along with links to further resources. Some are short, some are long, some have catchy titles. The page below will give you a handy way of looking at each state's narrative as well as their climate summaries. View the series at http://www.cocorahs.org/Content.aspx?page=50StatesClimates.
