There are published ASHRAE tables for given locales which can be used to establish specific heating requirements. Based on these tables, daily records of both high and low temps can be used to determine differentials or departures above or below a given temperature on an hourly basis to provide a forecasting of heating or cooling requirements.
Such extractions are called "degree-day" projections if my poor memory serves to recall.
