As I remember it, humid air is MORE dense than dry air. However,
barometric pressure decreases as a result of the amount of air, not
the humidity of the air. High pressure areas (such as a storm) move
toward the low pressure area. That's why low pressures mean an
eminent storm.
Now that I've confused the issue, is there someone out there who can
tell us which is correct?

In fact, Will, you have mis-remembered! Humid air is LESS dense than dry
air, which is why the barometric pressure falls with approaching rain.
