My brother lives in Chicago. The high temperature today is projected to be -11! I talked with him briefly yesterday - he was taking his son to a hockey game and had just gotten a flat tire. So there he was waiting for AAA in 15 degree weather. On Saturday he sent me a photo of a portion of their roof with 2ft icicles hanging from it. Beautiful - but only at a distance. He and his wife had to go to work today.
Being a Californian who was raised in Arizona I can't even begin to imagine how cold -11 is (wind chill of -30ish). When I lived in Tucson, we would watch the weather "back east" (which is what we called Chicago and the mid-west) or on the east coast. Whenever they had a particularly brutal winter, we knew to prepare for the influx of new residents who were done with the cold.
So my guess is this Spring and Summer Tucson will see a rise in population. I mean, enough is enough! At least it might help the property prices rise which would be good. But for all those people living through that horrific weather, here's hoping you warm up soon!
