A rare winter storm charging through Texas and the northern Gulf Coast left New Orleans and Houston frozen Tuesday, closing highways, grounding nearly all flights and canceling school for millions of students more used to hurricane dismissals than snow days.

Some flights scheduled to leave Dallas airports for Houston airports Friday were canceled amid the snowy weather in North Texas. Aviation tracking company FlightAware shows live updates on the flight status from Dallas to Houston.
