The ARWpost software also includes utilities (look in the util subdirectory) that can make a .ctl file from your WRF history dump file so you can view the raw output in Grads without first post-processing it. It would probably take you less time if you go this route, but you will have to manually compute relative humidity in Grads then. It isn't required of you to compile or run ARWpost to use these utilities.<div>

plotting onto native grid is the right way to go, but grads doesnt have a better way to give you the map on native grid yet. </p>
