[ncl-talk] Problem with WRF/WPS/GFS New Data

[Jared Lee]

Hi Barry,

The wrf-news listserv announced a week ago the release of WPS v3.9.0.1 to
handle the changes resulting from upgrades to operational GFS. And here's
the page with more info on the WRF users website:

Does using WPS v3.9.0.1 solve your issue, or are you experiencing this
issue with WPS v3.9.0.1? [Note that I'm not a WRF support person.]
