In September 2008, the National Weather Center hosted an Advanced Weather and Society Integrated Studies (WAS*IS) workshop. This workshop was designed to bring together research meteorologists at the NOAA Hazardous Weather Testbed experimental warning program, and a group of stakeholders representing a diverse user community, to integrate societal impact research at the beginning stages of the development of new gridded probabilistic hazardous weather information. The objectives of the workshop were to: 1) introduce new technologies/directions to a diverse spectrum of potential future collaborators, 2) define and address the needs of a broad spectrum of end-users, 3) clarify and suggest new ways to communicate uncertainty and storm information via emerging technologies, 4) define new measures of success to properly assess service, including changing concepts of storm verification including close calls and false alarms, 5) provide suggestions for the evolution of the Experimental Warning Program, designing spring experiments with stakeholders goals, 6) develop ideas for new ways to change the culture within all levels of the National Weather Service to facilitate operational implementation of these concepts, and 7) create visibility and consider possible future funding opportunities for Hazardous Weather Testbed activities and stakeholder interactions. We will discuss some of the outcomes of this workshop, including the cross-over activities with the development of a Next-Generation Warning Tool for the NWS.
