Also sorry if I haven't done enough digging on the program so far. I am assuming some of data gathered are also METARs? Are multiple data sources being used to produce the results?

Pilot in the U.S. here. This would be a great visual tool for preflight planning! Of course, I would call flight service station and use the NOAA website for more extensive weather data, but how recent can the program obtain weather data? Wouldn't make sense to use weather data from 6 hours ago for a flight. :P It would just be a cool resource that is aesthetically pleasing compared to the archaic feel of the NOAA website.
