Very little FM, but as the EMF generated by lightning ranges from near
DC to gamma rays, you likely need to be a bit more specific.

There are these for free:

There are also papers that cost to get if you are interested.

I expect that when the OP says AM and FM he means medium wave and VHF
broadcast frequencies. The loud impulse noises one hears on a radio
during storms tend to confirm that quite a lot of EM energy is put out
at all frequencies, as you say. Even FM radios usually fail to reject
it completely, but then they may be receiving it in their audio
circuits.
