The NMME produces predictions out to seven months on the National Weather Service (NWS) operational schedule. These predictions are relied upon by NWS Climate Prediction Center (CPC) forecasters to generate a variety of products, including U.S. temperature and precipitation anomaly outlooks, the Drought Monitor, and El Niño-Southern Oscillation (ENSO) forecasts.
The NMME system has provided routine real-time seasonal forecasts since August 2011 that adheres to the NCEP/CPC operational launch schedule.

The colored lines represent the current ensemble mean ENSO forecasts for each individual model system in the NMME. The histograms (sets of colored rectangles) convey the forecast probabilities of different ENSO conditions based on the entire multi-model system.
