Polar Vortex

We've got the furnace running, the faucet dripping (to prevent frozen pipes), and the humidfier blowing mist into the air. It's still not enough. The house's air temperature is 58F, even though the thermostat is set at 70F.

It's crazy cold. This thermometer is not accurate, but it gives you an idea of the cold. It should read around -31F.
