Why does low pressure air rise to produce rain?

In midlatitude quasigeostrophic theory, the rising of air in low
pressure areas and the corresponding sinking of air in high
pressure areas are secondary circulations required to keep
the atmosphere in hydrostatic balance. More simply, low
pressure draws air in towards it's center and the air has to
go somewhere, it can't go right back out against the pressure
gradient that pulled it in to begin with, it can't go down into
the ground, so it goes up. As it goes up, the air cools and
so can hold less water vapor, creating a tendency for rain.
