This workshop will provide a forum for cross-community dialog and sharing of the latest research results and work on integrating science with services. It will highlight recent advances in short-term climate predictions of conditions concerning water availability (e.g. precipitation, snowpack, drought) over the western U.S. to better inform water resource managers, and on translating climate forecasts into products to directly inform water management decisions. While the workshop topics will include the subseasonal range, emphasis and priorities for presentations and discussion will be on 1) seasonal to interannual lead-times, 2) seamless prediction systems across time scales, and then 3) subseasonal lead-times.
