Major Update of Local U.S. Climate Data Due by June 30
Each decade, NOAA's National Climatic Data Center updates its data for 30-year averages for a range of climate indicators. The most widely used "normals" for the period 1981-2010 (including temperature, precipitation, snowfall, snow depth, and heating and cooling degree days) are scheduled to be released at the end of June 2011, with the rest by year end.
