A powerful winter storm affected dozens of US states with snow, sleet, and freezing rain for several days. The storm has moved offshore, but cold air remains over central and eastern parts of the country. Snow, ice, and freezing rain caused deep accumulations, icy roads, and disruptions. Travel is still tough in many places. Schools and services are impacted, and warnings stay active. The Northeast saw some of the highest snow totals, with Massachusetts, New York, and New Hampshire reporting over 20 inches. Connecticut, Rhode Island, and Maine recorded heavy snow in the high teens. Crews are clearing roads and restoring transport but progress varies. In the south, ice and sleet caused problems in Arkansas, Mississippi, Louisiana, and parts of Texas. Ice on trees and power lines led to outages and dangerous driving. The Midwest and Ohio Valley had steady snowfalls between 10 and 16 inches in places. Illinois, Indiana, Ohio, Pennsylvania, and West Virginia faced harsh winter driving and mixed precipitation. Rural areas are slower to recover than cities. Mountain areas in Colorado and New Mexico received over two feet of snow. This heavy snow raised avalanche risks and closed mountain roads despite local experience with winter weather. Weather officials now warn that dangerous cold air has settled behind the storm. Many central and eastern US locations will stay below freezing by day, with some areas dipping below zero overnight. People are urged to limit outdoor exposure and check on vulnerable neighbors. Lake-enhanced snow may continue around the Great Lakes, with another system possible later this week. The West Coast faces a new weather pattern bringing light rain to California and snow in the Cascades. While the storm has moved on, its effects remain in piled snow, ice, and cold mornings. Information from the Weather Prediction Centre confirms the ongoing challenges as winter continues to grip much of the country.
