A number of diagrams are shown, contrasting day-by-day average temperatures at Washington with the accepted “normals”, showing extreme highest and lowest temperatures for each day of the year, the “January Thaw,” a recurrent cold period in February, an estimation of the potentially highest and lowest temperatures at Washington, and recent abnormal temperature trends are discussed. The annual day-by-day march of degree days for heating is also noted. The results in general suggest some revision of the popular conception of “normals” is in order.
