Sea-level pressure (black contours every 4 hPa), 1000–500 hPa thickness (red contours every 6 dam), and 250 hPa wind speed (shaded in m s-1).
Forecasts are from the NSSL MPAS model also available here.
Output variables are interpolated to a 0.1x0.1 degree latitude-longitude grid. Sea-level pressure and 1000–500 hPa thickness are smoothed with a 9-point local smoother run 10 times.
