The extreme cold in the US is being caused by the 10th and coldest polar vortex event of this season. Meteorologists have explained that this phenomenon occurs when weather forces in the Arctic push chilly air that normally remains near the North Pole southward into the United States and Europe. This displacement of Arctic air is creating unusually cold conditions across parts of the country, leading to severe temperature drops and dangerous wind chills in affected regions.
