NOAA's National Climatic Data Center has released new climate normals covering the 1981-2010 period. The new climate normals are available for over 9800 stations including stations in Alaska, Hawaii, and U.S.-affiliated stations in the Caribbean and the Pacific. The product portfolio includes station-based climatic averages of temperature, precipitation, snowfall, and heating and cooling degree days on daily, monthly, seasonal, and annual timescales. Also included are probabilities and percentiles of precipitation, snowfall, and snow depth. For over 250 first order stations, hourly-based normals of temperature, dew point temperature, wind chill, heat index, heating and cooling degree hours, mean sea level pressure, and various cloud and wind parameters are also provided. In general, the 1981-2010 temperature normals are about 0.5F warmer than the 1971-2000 temperature averages. In terms of annual precipitation, conditions are slightly wetter over the Midwest and slightly drier over the Southeast compared to 1971-2000.
