This might work:
Protect them from wind in bags, mulch/insulate with pine needles, straw, shredded newspaper, bubble wrap or Styrofoam packing material. Use a like a 5 gallon garbage bag, a layer of insulation, your pots in trays with a touch of water and bury in insulation. Place near a wall that gets the least exposure to wind if possible. You could put them, insulated, in garbage cans with lids. Just make sure they don't get dumped out or trash dumped on top of them.
