The Annual issue contains monthly and annual averages of temperature, precipitation, temperature extremes, freeze data, soil temperatures, evaporation, and a recap of monthly cooling degree days
Typically, cooling degree days
are calculated as how much warmer the mean temperature at a location is than 65 degrees Fahrenheit on a given day.
Regression (6) employs cooling degree days
and finds that the hotter the summer, the lower the death rate.
The weather in the third quarter of 2010 was the warmest in recent history, with cooling degree days
(a measure for determining the impact of weather during the summer months) 44% higher than normal.

The reduction in utility gross margin for the third quarter 2004 was primarily due to the electric rate decrease implemented in September 2003 and to decreased sales volumes caused by cooler weather, as cooling degree days
declined over 28 percent quarter-over-quarter.
