The National Climatic Data Center is the central repository for historical weather records. This does not necessarily mean that they have all weather data that may have been observed at a particular location, but they are regarded as the most complete archive for climatological data from the United States as a whole. They can be reached on internet at lwf.ncdc.noaa.gov.
