Following Dallas flight cancellations this week, the storm has now caused major disruptions at major Southeast hubs.

Any wintry precipitation in Oklahoma and Texas should end in the morning. Snow will fall from the Mid-South region into Kentucky, Tennessee, far northern parts of Mississippi, Alabama and Georgia into North Carolina, upstate South Carolina and Virginia.

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.
