Hi Jay,

Yes, in order for a towered Airport to be class "D" it must have
surface based weather observation cabability, if not it is class "E"
and in some cases class "G" airspace. And as I believe others have
already said, only Class "B" airspace provides VFR seperation, hence
the 3SM visibility, clear of clouds VFR minimum.

Aren't you forgetting about class E?
That is labeled "controlled", too, but hopefully even the dumbest pilot
would not expect VFR traffic separation by ATC in class E.

We're talking about tower-controlled airspace here, methinks.

Are there any Class E towers?
