It's not just about the temperature, it's also about how quickly the temperature is dropping. Usually when the temperature goes down, trees do some "clever" shit with the sap inside them, specifically so that there's less moisture in them and when it freezes and expands the tree doesn't crack. However if it drops too quickly the trees can't do their magic quickly enough, too much water freezes, puts too much stress on the tree and it may crack.
