Re: wmbarb not working with Lambert Conformal projection

I tried to remove res1@tfDoNDCOverlay = True, but it didn't work either.
The map just looked messed up and it still didn't print any wmbarb
observations.

I just want to point out that everything else, for example gridded wind
barbs, contoured fields etc., work just fine with that configuration.
Just not the observations plotted with wmbarb.

Thanks,
Antti

Try removing the
