The NOAA National Climatic Data Center recently released updated climate normals for the 30 year period 1981 – 2010. The climate normals are averaged across 30 years and updated every decade. On average, the U.S. climate was warmer than the previous 30 year measurement period (1971-2000) with most of the increases in winter and night time minimums. The climate normals include daily, monthly and annual minimum and maximum temperature, precipitation and derived measures such as heating and cooling degree days. The data are available for download from the National Climatic Data Center.
