The former. I raised exactly this issue in the consultation.
(My comment) The "surface vis and wx" entries don't appear to pair up with the "cloud" entries as they do on the F215. This is confusing. Is a cloud group, for example, associated with OCNL reduced vis in SHRA, or is it independent of them?
(Response) There is no longer a need to pair up cloud with vis and weather but the forecasters can if they wish when constructing the charts.
I think that's a needless loss of information, but compared to some of the other shortcomings of the "new and improved" F215, it's no big deal.
