What i believe happens is that with very moist/damp air being accelerated over the wing the temperature drops and cold air can hold less moisture than hot air, therefore you see a release of moisture over the wing.
Something like that.

Humidity and the dew point temperature relative to ambient temperature are the main atmospheric factors, though.
