At least 46 million people were under a winter storm warning as of Thursday as the storm spreads along the Gulf Coast Friday, according to the weather service. The storm should weaken by Saturday, bringing lighter snow between 1 and 3 inches to parts of the Northeast, the Mid-Atlantic and the Ohio Valley before exiting off the Carolinas.

Travelers heading to some of the nation's busiest airports in the next two days should expect delays and canceled flights.

The second major winter storm of 2025 will target the south-central and southeastern United States into the weekend and will create dangerous conditions on the roads as well as a slew of flight delays and cancellations from Dallas to Atlanta and Charlotte,
