The Local Analysis and Prediction System (LAPS) is a highly portable, computationally efficient numerical weather prediction (NWP) data assimilation and nowcasting system. Within the National Oceanic and Atmospheric Administration (NOAA), LAPS is used operationally on Advanced Weather Interactive Processing System (AWIPS) platforms at National Weather Service (NWS) Weather Forecast Offices (WFOs). NWS applications of LAPS include severe, winter, fire, hydrometeorological, tropical, and aviation weather forecasting. Building on the success of the first LAPS User Workshop, the second LAPS User Workshop was convened jointly by the main developer and user groups of the system, the Global Systems Division (GSD) of NOAA's Earth System Research Laboratory (ESRL), and the NWS Office of Climate, Weather, and Water Services, respectively.
