Official daily normals are calculated by the National Climatic Data Center using a linear interpolation of the monthly normals. Since the daily normals do not account for daily climate variability, the State Climate Office of North Carolina provides a daily normal 'range' that incorporates the historical variations in climate for any given day. More details on this technique are available in:
