I posted this question in the //42 typical weather thread but I guess it got kinda lost there so I might just start its own topic on this as I never really quite understood what happens in these scenarios.

I usually just put it to live weather and accept whatever it is but one reason I also don't tend to change the weather is when I fly with ATC, I use batc I'm not sure what would happen if I choose custom weather, whether it's an add-on or within the sim options itself.  If this custom weather changes the wind directions/speed etc and subsequently also changes the active runways does an add-on like batc know that I am on custom weather or is that always going to base itself on real life weather 

Thanks

BATC allows you to use historical weather data.
There is a slider in the settings to enable this feature.

Can batc match the weather with historical flight schedules?

Hello,

You can use ActiveSky where you can select historical weather and FSHud that is fully integrated to take weather from ActiveSky.
This will give you completely synchronized weather experience (for current or historical weather preset in ActiveSky).

Historical weather then works for "any" custom weather preset I use, overcast, thunderstorms etc because "actual historical" weather is not something I tend to use though.
