This uses a bash-specific feature:
cmd > >(tee file); status=$?

This should work on any sh:
exec 3>&1 && status=`exec 4>&1 && { cmd; echo $? >&4; } | tee file >&3`

Or, if you don't want to clobber any descriptors, in case they might
be in use for something else:
: > file &&
{ tail -f file & } &&
pid=$! &&
{ cmd > file; status=$?; } &&
sleep 1 && # give tail a chance to print the last bits that were just written
kill "$pid"
