Strong winds brought down power lines in the region, leaving about 1,000 Public Service Company of Oklahoma customers without power, including Liberty Elementary School in Broken Arrow which canceled classes for the day.

PSO officials estimated all power would be restored by Tuesday night.

The chance for snow will last through Tuesday night as both systems mowe out of the state. Chilly temperatures are expected early Wednesday, dipping into the teens in northwest Oklahoma and the 20s in the Oklahoma City metro before temperatures gradually begin to climb later in the week.

Another cold front is expected to move into Oklahoma by Sunday.

To prepare for winter weather, the Oklahoma Highway Patrol recommends making sure vehicles are in good working order and that motorists prepare a "go-kit" that includes a blanket and winter clothes, including gloves, said Lt. George Brown. Motorists should increase following distance, reduce speed and pay particular attention to bridges and overpasses, where slick spots can develop quickly in cold weather.
