Data assimilation experiments using an ensemble Kalman filter (EnKF) will be carried out with the National Severe Storms Laboratory Collaborative Model for Multiscale Atmospheric Simulation (NCOMMAS). Ensemble analyses and forecasts for different periods during the evolution of the storm will be produced from experiments assimilating data from both the PAR and WSR-88D radars and experiments where only WSR-88D data are assimilated. The resulting analyses and forecasts will be compared to assess the impact of assimilating rapid-scan PAR data on convective-scale forecasts at different points during the evolution of the storm with an emphasis on an ability to accurately analyze and forecast the development and track of the El Reno tornado.
