Snow!?

I am in New Hampshire and its snowing. Flurries, first of the year. My question is I have all my plants still in the shed ready to go out but im worried about them going out in the snow as I am a first time grower. They are so close to being done I just want whats best for them. Can anyone please give me some advice on this matter, your comments will be much appreciated.

no way to move them inside?

I do not have a spot in my house that has a giant window or a big light source. So outside they are....

ahhh... If it's around freezing I wouldn't put it out there....
