North America shivers in an Arctic freeze….biting, bitterly cold breezes….brutal, potential, record-breaking low temperatures….Polar Vortex– that arctic cyclone that’s swept down from the North Pole ….what’s next? Frost Quakes? They did happen in Ontario, Canada, on Christmas Eve. Apparently, some kids there thought that the loud snap sounds and the shakes were reindeer on the roof. Closer to home, parts of Ohio experienced Frost Quakes in 2011. It’s winter!
