The North Texas Tollway Authority began plowing toll roads with convoys Thursday night, using motor graders and truck-mounted plows to move snow and slush to the shoulder and applying deicer. That work will continue throughout Friday as staff work 12-hour shifts.

Thursday brought snow to parts of North Texas and the Panhandle. Here are the totals, and when Texans can expect road conditions to improve.

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.
