Preliminary Local Climatological Data

 The Preliminary Local Climatological Data Sheet summarizes temperature, heating and cooling degree days and precipitation and snowfall. This is preliminary unofficial data compiled within our office, and may contain erroneous or incorrect data.

Official published climatological data can be obtained from the National Centers for Environmental Information (NCEI) in Asheville, North Carolina for about 300 locations nationwide for a small charge. The data can be purchased via the Internet, for both online display, or hard-copy printout as well. Official monthly publications also contain 3-hourly weather observations for that month and an hourly summary of precipitation. Annual LCD publications contain a summary of the past calendar year as well as historical averages and extremes.  Please note that Official LCDs are not available for FFT and BWG.
