All the maps use the same color scale, ranging from dark blue for the coldest temperatures to dark red for the hottest. The temperatures are state-wide averages calculated from data collected by weather stations throughout each state during the years 1971 to 2000 and made available by the NOAA National Climatic Data Center of the United States.
