The Unified Forecast System (UFS) Workflows meeting was held 29-30 June 2021, which was a follow-up to the UFS Workflows workshop held virtually 29-30 April 2020. The June 2021 meeting was spread over a two-day period (each 2-hour duration). The organizing committee included UFS collaborators from the Developmental Testbed Center (DTC), George Mason University (GMU), the National Oceanic and Atmospheric Administration (NOAA), and the National Center for Atmospheric Research (NCAR). The logistics of the virtual meeting were provided by the DTC. The aim of the workshop was to continue communications across the modeling groups and translate communication into concrete steps to improve workflows across the UFS. The meeting was attended by 17 participants, which included participation from Environmental Modeling Center (EMC)’s management and UFS leads. The report from this meeting provides an overview of the presentations and a summary of the extensive discussions that followed.
