Possibility of non-existent METAR generation

[alexpro]

I wrote simple C++ program, which reads airport coordinates from airports.xml file created by mkrwys utility. My program used SimConnect_WeatherRequestInterpolatedObservation() function for get current weather in airport area and creates very simple METAR which enough for properly runway assignment. And in addition program does the same as scripts described in above post - adds non-existent METARS to result weather file.

If that interests you, I can give you program and source code.
SimConnect part is really simple, and maybe my way of METAR generation isn't quite right, but in all my cases all seems to work OK.
