CLIMATE PROJECTIONS 

FOR 

THE STATE OF GEORGIA

The data in Table 1 and Table 2 below were extracted from the National Weather Service’s Climate Prediction Center.  Details on models, methods, and other relevant discussion can be found on their website.

Mean temperature is defined as the average between of maximum and minimum temperature.

The 50% confidence interval can best be described by an example. Suppose the mean temperature is 55.5, and the 50% confidence interval is 48.2 to 58.6. There would be a 50% probability the mean temperature will be in the range from 48.2 to 58.6. The best estimate within this range is the mean (55.5).

The Tables will be updated at the beginning of each month when these data become available from the Climate Prediction Center.
