Oof, that was a brain workout. Alright then, let's say that we don't look at temperature change. Let's think ultra simple and see how humidity affects the MALR.
With a decrease in humidity, there will be less water vapour in the air. This means that there will be less water vapour pressure of saturated air (less water vapour anyway, less force exerted).
This means the mixing ratio of the mass of water vapour to the mass of dry air will decrease, and given by the MALR equation, the MALR should be of a lower value. Heat capacity does come into play too.
