Hi Jeff, that's clear now.
for a fast solution, you can try to put in the mapfile all this  
layers and then show/hide them when selected or not.
You'll have to hack the legend or show all layers/pressure combinations.

then, as they are meteo data you'll maybe want to redraw their caches  
with some interval, so:

Mapfile_Metadata_Configuration#Mapfile_LAYER_Section

hope this helps

ciao
