(1) 850 hPa smoothed (N=10) relative vorticity (shaded in 10-5 s-1) and nondivergent wind (barbs in knots).
(2) 850 hPa smoothed (N=20) geostrophic relative vorticity (shaded in 10-5 s-1) and smoothed (N=5) geostrophic wind (barbs in knots).
(3) 850 hPa height (dam) and geostrophic wind (barbs in knots).

Forecasts are from the NSSL MPAS model also available here. Output variables are interpolated to a 0.1x0.1 degree latitude-longitude grid.
Select variables are smoothed with a 9-point local smoother run N times.
