Not that I'm aware of ...
Actually I talked to the person who accumulates all data of all weather stations which supply data to the KNMI and there is very limited data free to the public. A few years ago our government started to commercialise every public company, so a lot of data isn't available (as I only just started with this hobby, I don't really know what the situation was before).
There's only one webpage with METARs available. And that page is discussed before (don't know when and where exactly, but I can search for it ...).
BTW: I keep missing "unread" messages all the time. They just don't turn up in my list
