The National Centers for Environmental Prediction (NCEP)'s Time-Lagged North American Rapid Refresh Ensemble Forecast (NARRE-TL) provides probabilistic guidance out to 24 hours. The Environmental Modeling Center (EMC) is responsible for the enhancements, transition to operations, and maintenance of the NARRE-TL. The forecasts are made hourly by NWS Central Operations.
