Hi Rob,
I’ve just uploaded a version of WXSIM that has at least one reliable (I just checked all options that I now have) for every data type, and also bypasses the problem of the TLS1.2 thing using a proxy server Sam Bohler set up for me. I actually omitted (more like “hid”, as the URL’s are remmed out in my code, in case I need to bring them back) all the FSU links, because they say their data is only for research (bolded) purposes, not “commercial” ones. WXSIM isn’t high-level “commercial”, but as I do seel it, I wanted to be careful about that. Have you contacted them to get permission? I think you register your URL? There might still be an SSL/TLS problem there, even with registration, and the proxy server is on my end. Let me know what you’ve found, and your thoughts on that. In any case, there IS now a source for everything! 
The new WXSIMATE to try out (just the .exe, not an installer is at
