Quick tomato question

Quick tomato question

I was hoping to buy tomatoes and bell peppers (and a lot of other plants) this weekend at a garden show. They will be planted in my freshly mulched and prepped garden bed. The last bit of cold weather is determinedly sticking around, which means 44 degrees Sunday night and 41 Monday night before getting back up into the 50s at night. Will this be too cold for tomatoes and peppers? Of course I just put the trash and recycling out today so I don't have any good plastic containers to make into covers.
