You need to check your antifreeze ratio, or if you can't do it have any reputable repair shop check it for you.

You will see some freezing of thin lines or narrow water passages first, before your block freezes hard enough to expand and crack it. But you can't take a chance ruining your engine. If you end up not driving the car for a few days and get a really bad cold snap your engine could be finished.

In fact I would consider bringing your ratio of coolant up to 65%, which should make you good to about -50F.
