Temp fluctuation affect?

It's true that lowering the temp will decrease the relative humidity
reading, but it will NOT mean that more moisture is present.  Relative
humidity is just that...relative!  The absolute amount of moisture present
will not change solely by lowering the temperature.

The difficult, I do right away.  The impossible takes a little longer.
