            National Oceanic and Atmospheric Administration’s Climate Prediction Center produces long-range generalized climate forecasts based on the average of seven different General Circulation Model simulations. These forecasts are released on the 8th day of every month with predictions of temperature and precipitation patterns over North America for the next seven months. The correctness of these forecasts becomes less with lead time. For this reason only three months are shown. The skill of these forecasts are better for temperature compared to precipitation, and are particularly good for temperature during winter and spring when El Niño or La Niña events are occurring.  Finally, these forecasts are generally poor during neutral ENSO years (El Niño or La Niña are not occurring).

            The predictions for each month describe the anomaly from the 1991 to 2020 average. Prediction maps for temperature and precipitation for the next 3 months are shown below. Also shown is the forecast for the current month from the previous model run release.
