As a non-aviator, I don't know what any of that shit is. As the son of an aviator (my father had a pilot's license when he was younger, but he didn't keep it as I guess you have to fly so many hours a year to keep it), I want to help you, but I'm not sure I can.
I was given this link a few years back, and I've kept it, though I rarely check it. I just did, site is still up. Is this closer to what you want? https://www.ventusky.com/ If not, sorry; again, I don't know what all that means, but someone said it was a different/better kind of weather app/site.
