All Houston airports will reopen Wednesday after shutting down on Jan. 21 as a winter storm barreled through South Texas.

Houston is preparing for a historic winter storm expected to bring up to 6 inches of snow, a rare event not seen in decades.

A rare, historic snowfall blanketed parts of the southern U.S. on Tuesday, allowing residents to play in the rather unusual weather. Families went snow tubing in Houston. People made snowballs and snow angels. People were even seen skiing on Bourbon Street.

A rare frigid storm charged through Texas and the northern Gulf Coast on Tuesday, blanketing New Orleans and Houston with snow that closed highways, grounded nearly all flights and canceled school for more than a million students more accustomed to hurricane dismissals than snow days.

Snow and sleet from Texas to the Deep South and Outer Banks caused ice buildup in cities like New Orleans, Atlanta, and Jacksonville.
