Spray paint in cold?

Quick question for our Rust-Oleum experts. I have a shed that I've converted into my paint shed. It is where I do all my spray painting and prepping of my furniture pieces. It is NOT heated. We are supposed to dip below zero. I have at least thirty full spray cans out there. Is it safe to leave them out in the cold. I don't want to have unusable paint this summer...feeling lazy as well though! Lol!-deep snow and winds..suck it up and wade out there and rescue them or don't worry they'll be fine?
