I live way in the Southern US, we are feeling the sting of this cold weather. Oddly haven't felt this cold down here in years, but was an every hear occurrence when I was a kid. Still waiting on the next ice storm, but that isn't coming and it's been about 6 years since the last one, was used to seeing them more commonly when I was a kid.
We won't be bitter cold, but temps under 20 degrees have been a major rarity in this part of the US the last 10+ years. I do remember one time as a kid school was canceled because the temperature had hit 9 degrees in the morning, and the schools heating went out.
