When you start the FSRealWX program and connect it to X-Plane, weather data is uploaded to FSRealWX, written to the weather files (this is the connection method I am writing about), but x-Plane is read only when the next weather update is made, depending on the "Update Time" setting, before that the "standard weather" settings remain in the simulator, which naturally does not correspond to reality. It seems to me that after writing real weather data to the weather transmission files (METAR.rwx, WINDS.rwx) XPRealWX should immediately give the X-Plane command to count them and update the weather.
