A deadly storm system lashed a large swath of the southern US with bands of sleet and snow for a third day on Wednesday, grounding an additional 2,300 flights, leaving hundreds of thousands without power, forcing school closures and making already treacherous driving conditions worse.
Watches and warnings about wintry conditions were issued for an area stretching West Texas’ border with Mexico through Oklahoma, Arkansas and Louisiana, and into western Tennessee and northern Mississippi. Several rounds of mixed precipitation, including freezing rain and sleet, were in store for many areas throughout the day, meaning some places could get hit multiple times, forecasters said.
