Long-range climatological forecasts are produced by the Climate Prediction Center (CPC), a branch of the National Weather Service.  These include 8-14 day outlooks, monthly outlooks, and seasonal outlooks.

Unlike regular "zone forecasts" issued by a local National Weather Service office, the climatological outlooks provide probability forecasts for both temperature and precipitation, divided into tercile groups: below normal, near normal, and above normal. For information about how to read the latest 8 to 14 day outlooks, for example, click here.
