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

Snow and ice and snow are accumulating on bridges and overpasses of major highways, according to TxDOT. Motorists should drive with caution and expect traffic delays.

As snow, freezing rain and sleet make their way through North Texas this Thursday and early Friday during the winter storm, most schools and offices are closing their doors, but many other services will remain open.
