If it is still in the refrigerator, maybe the temperature swing at night will keep it cool enough. Inside the house the temperature will not fluctuate quite as much as out and inside the refrigerator even less. I would think as long as it gets cold at night and lowers the temperature again and it doesn't stay 50 degrees, you will probably be ok. I would use the milk in the fridge as a judge, if the milk went bad, everything is possibly bad but if the milk is good, it didn't ever get very warm in the refrigerator. It just doesn't take much to ruin milk
