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:

Holder, C., R. Boyles, P. Robinson, S. Raman, and G. Fishel (2006). Calculating a Daily Normal Temperature Range that Reflects Daily Temperature Variability. Bulletin of the American Meteorological Society, Vol. 87, pp 769-774.
