Annual Temperature My topic will in a sense be a summary of the group’s data. Rather than looking at a particular season, I will be looking at the annual averages for both temperature and precipitation (rain and snow) over the past century (I may look for data that goes further back for the final project) Between 1936 – 2008 Maximum in 1998 with 57.9°F Minimum in 1940 with 52.4°F Trend shows that there is a slight increase in temperature
Annual Precipitation Between 1933 – 2002 Maximum in 1979 with 126.08 in Minimum in 1933 with 58.37 Trend shows there is a slight increase in precipitation over the years
