I thought I had fixed this problem last winter but now it's back again.
When water is turned off upstairs the cold water pipe rattles against
the drywall. It started happening the same time last year. It seems that
when the outside temp falls down to the 40s and 30s is the only time it
happens. Does the ground being colder have something to do with the
water being heavier?

I once owned a house from the 20's where an old Saturday Evening Post was
wedged between pipes and joists to silence things a bit.

if you have basement access try holding on there while someone tries
to create noise.

may be possible to push on lines to stop noise, most easily tried by
using your hands and pushing pulling etc on lines
