This session provides an overview of recent advances in prediction of atmospheric phenomena beyond the weather scale. Modern skill in short-term weather forecasting and climate-scale projections have increased stakeholder demand and scientific interest in the use of weather and climate data outside of traditional timeframes. The convergence of these interests is no more evident than in the Subseasonal to Seasonal (S2S) range. A myriad of approaches and tools are being implemented to increase skill in temperature, precipitation, and high impact event forecasts beyond two weeks. Traditionally, both climate- and weather-scale methods, primarily statistically-focused, have been ported to this temporal range. Innovative methods are bringing new perspectives and capabilities to this "gray area" of predictability setting the stage for broad dissemination of actionable S2S information across the economy.
