At least there was no wind! (Actually, that's probably one reason it got so cold in the first place; wind helps keep night-time temps warmer than those of a clear, still night.)
Believe me, I'm feeling for all of you starting the morning with negative numbers. I don't know if my thermometer would even be able to register negative numbers…
PS: My house really isn't 59°; I had taken the unit outside to try for a non-flash photo. It hadn't recovered yet.
