Real world weather apps are really hit or miss since the MSFS weather is based on a forecast model that’s 12+ hours old vs actual real time conditions. Like any forecast, it may be correct, it may not be. So at best you might luck into weather and winds actually matching up to real world atmospheric conditions, or being at least somewhat similar. But much of the time, the variation is enough to render real world meteorological charts either useless or of very limited value.
Hopefully the SU7 overhaul of the weather system helps with this. It would be nice to be able to rely on real world tools that pilots actually use.
