Parts of Houston were also hit with sleet and ice, snarling traffic. In the west, El Paso suffered through a fourth day of arctic weather that has caused blackouts and natural gas shortages.
Dallas bore the brunt of the storm. Snow forced officials to close the city’s in-town airport, Love Field, the corporate home of Southwest Airlines, from 3 a.m. until noon. The snow also forced airlines to cancel more than 300 flights at the region’s main airport, Dallas/Fort Worth International, creating headaches for people trying to get to the Super Bowl in Arlington, which is between Dallas and Fort Worth, on Sunday.
