Are new Raid bosses being introduced?

Not sure if we're going to see anything until the ones that were in the system prior to the end of the event end. I still see a Groudon raid at a gym near me, for example.

Apparently Charizard is back, so I assume any flying/psychic/dragon that was ever a raid boss can appear?

I see scyther, exeggutor, aerodactyl, claydol, slowbro and alakazam in nyc

I was wondering that too. I hope so because I agree with you about if they are going to make the current windy ones occur more would suck.

I read that sentence and believed for a moment that if you do a Raid at a nearby gym, windy weather Pokémon will spawn there...
There is some very ambiguous wording there.
