Around 40 million people in the U.S. are under a winter storm warning from an unusual blast of severe cold weather and snow across the South.

A rare winter storm charging through Texas and the northern Gulf Coast on Tuesday has closed highways and airports and prompted the first blizzard warning for southeast Texas and southwest Louisiana.

A week and a half later, another part of Texas is being threatened by snowfall from another winter storm that will move across the central and southern parts of the state. This area rarely sees snow and according to the National Weather Service, some areas could see as much as 5 to 7 inches of the white powdery stuff.
