250 hPa wind speed (red contours every 10 m s-1 starting at 30 m s-1), relative vorticity (black contours every 5x10-5 s-1 starting at 5x10-5 s-1), divergent wind (arrows in m s-1), and 1-h precipitation (shaded in mm).
Forecasts are from the NSSL MPAS model also available here.
Output variables are interpolated to a 0.1x0.1 degree latitude-longitude grid. Relative vorticity is smoothed with a 9-point local smoother run 10 times.
