We had the cold for a couple of days there. Finally topped 0F yesterday, and is climbing fast now. We hit -21F at the coldest, with windchill at -55! I have never seen that kind of cold here. The wind was mostly just random gusts, but even without the wind, -21 really bites.
Coldest I can recall was -14F from around 7 or 8 years ago. This time around, inside at least, it wasn't too bad, as I had my furnace replaced a number of years ago. The new one is incredibly efficient, and kept the house warm without having to run 100% of the time. When it hit -14 in that prior year, I remember my heater running non-stop, and mostly just blowing cold air!!
