Impact from the new surge of very cold air may include the already familiar risks from below-zero temperatures including life-threatening conditions and frostbite. The cold may be intense enough to cause school closings, frozen pipes and water main breaks. Heating systems may struggle to keep up, people will spend more money keeping their homes and businesses warm and ice will again build up on area rivers. Where the cold is accompanied by snow, travel delays are likely.

The polar vortex will get stronger and move farther south later in January, causing cold to intensify in the Midwest and East and drought to build in California and the West.
