GSL is pleased to announce that Steve Weygandt has been selected as the new Chief of the Assimilation, Verification, and Innovation Division (AVID). Steve brings a wealth of experience and vision to the new position. Steve received an M.S. degree from Penn State University in 1991, researching mesoscale modeling. He earned his Ph.D. from the University of Oklahoma in 1998 in the area of storm-scale radar data assimilation techniques.

Steve joined NOAA GSL (then FSL) in 2000, and his work has focused on improving rapidly updated local forecasts of hazardous weather phenomena and working with users to best utilize automated weather guidance products, including ensemble-based probabilistic guidance. Steve has also helped to direct the development of data assimilation systems that provide initial conditions for the Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR) models and has helped transition multiple versions of these models to NOAA operations since 2012. He is currently helping to direct the development of the Rapid Refresh Forecast System (RRFS) that will replace the RAP and the HRRR as the NOAA regional model application of the Unified Forecast System.

With his extensive experience in various leadership roles within GSL and through his partnerships with other agencies, line offices, and the community, Steve is well qualified to lead AVID and its science into the future.
