Break-down voltage of gaps and humidity

Regarding humidity and the effect of it on break-down voltage:

In testing, I (as well as others) may have noticed that corona discharge
increases from a high voltage point in the
presence of increasing humidity.

However, in Kuffel's High Voltage Engineering text, he states that the
break-down voltage between two gaps will
actually increase with increasing humidity.

This seems to contradict what I have experienced.  Can anyone comment on
this?

Thanks
