What happens when a weather front moves towards a mountain range? I know
the mountain range acts as a barrier so it'll rain longer on the windward
side of the mountain range. Does friction also play a role? Does air
converge at the mountain range and cause the surface pressure to deepen? Is
there anything else I'm overlooking?

Thanks

I'll add two things. Surface convergence in the absence
of upper level divergence will lead to surface pressure
rises always, because more mass ends up being in the
column.

Surface fronts slow down as they approach mountains because
the denser air is blocked from progress by the elevated
topography.

Scott, really at notscape det not
