After several days of freezing temperatures, snow, sleet and rain fell in North Texas on Thursday, bringing travel disruptions in the air and on the ground, school closures and upending a region that doesn’t often see frozen precipitation.

Moisture and a mix of precipitation should start to move into the metroplex from the southwest starting in the morning to the mid-morning hours.

The National Weather Service said a tenth of an inch of ice could accumulate on raised surfaces, such as bridges, and some areas could get up to a quarter inch. But the main travel impacts are expected to be from sleet and snow.
