May get a random snow in a couple days. What should I do?

Sorry for the noob question but we werent expecting such cold weather suddenly and I am worried for my plants. I just potted up a couple plants. One is a hardware store rescue that may be still in dormancy.

I live in MN next to the Mississippi River. Usually warm and humid this time of year to get started with CP's. We are expected to get some snow showers at the end of the week which is really unexpected since it has been 65+ and sunny for the past two weeks. I just put my plants outside last week. Any suggestions on what I should do with the plants for a couple days until this passes? Or am I worrying for no reason? Thanks for your help
