Currently +5 F here as sunrise approaches, with tonight's low forecast to be -1 F.

Whenever the temps fall below 10 F recently, our deck seems to make violent "boom!" sounds as if someone had dropped a bowling ball on it. I suspect that one of the concrete sonotubes that hold the deck up is being heaved by the frost on cold evenings, stressing the wood until one of the joints finally slips like an earthquake on a fault line.....
