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. |

For information about how to read the latest 8 to 14 day outlooks, for example, click here.
