Advances in the skill of global ensemble prediction systems permits obtaining useful information even beyond the typical two weeks limits of predictability for atmospheric variables. A new prediction system setup was prepared at NCEP to produce probabilistic forecasts out to 45 days. The system is intended to provide a skill benchmark for uncoupled AGCMS and to provide a link between weather and seasonal dynamical prediction systems.
