I stumbled on this
EXPERIMENTAL NWS page this morning and couldn't resist scraping it. After modifying the presentation to reflect more of my style,
this is the result.
It currently lives as a separate page, and as long as it's not in production it will continue to do so.
It won't validate on an SSL site due to cross-site restrictions, but
it validates on my non-SSL testing site.
Edit 2018 Sep 1: I forgot to include a link to the NWS WPC page where this is found. Zip updated.
