| Abstract | In support of the Next Generation Global Prediction System (NGGPS) project, two severe weather outbreaks—occurring on 28 April 2014 and 6 May 2015—are simulated using the North American Mesoscale Forecast System (NAM) 1.33-km Fire Weather nest and 4-km CONUS nest, each with 5-min output. These model simulations are run in an effort to learn more about how convection initiates and evolves on convection-allowing model grids of varying horizontal grid spacing.
