Regions such as the Northeast, Appalachians, and mountain West may face significant disruptions due to heavy snowfall and extended cold spells. These conditions could impact transportation, infrastructure, and daily activities, particularly during mid-January and February. Conversely, milder winters in the Southeast and Southwest may reduce heating costs but could also lead to drought risks in areas with below-normal precipitation. The strengthening El Niño could further influence weather patterns, potentially creating unpredictable conditions in some areas.
