Ron,

Though you were talking about cabinet carcasses, the
same thing holds true for mirror boxes, rockers, and
other scope components.  Winter is a hard time to work
with sheet goods because of low humidity, especially
if you heat your shop.  It is important to store them
properly so that they lose and take up moisture
evenly--vertically on edge with a generous air space
between them.  If the panels cup anyway you can try
moistening the concave side with a slightly damp
sponge just before glueup, though sometimes this
results in a very wavy panel.  You might consider
moving the panels indoors and letting then "cure" a
couple days before assembly.  In my experience
components tend to flatten out once they are
assembled.
