How can I temporarily migrate the update folder to a USB drive for Systemupdate?

Iran apt-get dist-upgrade on my Raspberry Pi with Raspbian "Jessie", but unfortunately, my 16GB SD card does not provide enough space for the upgrade. Now I can not even use AutoComplete in my terminal. Is there a way to migrate the update folder to a USB drive? I could not find a solution on the Internet. Help would be greatly appreciated.
