Commuters on Thursday morning could be in for a challenging ride in.

Weather forecasters are calling for light snow on top of cold roads overnight, potentially making driving conditions difficult.

Snow accumulation is likely to be an inch or less in most areas, but recent cold temperatures will allow snow to stick to road surfaces. Most snow is expected to come between 7 p.m. Wednesday and 4 a.m. Thursday.

“If this threat of light snow on frigid roads does materialize overnight, the Thursday morning rush-hour could quickly turn icy on untreated roads,” the National Weather service said. “This could lead to hazardous traveling conditions, multiple accidents, and extensive delays.”

The Maryland Department of Transportation suggested drivers allow for extra time to navigate roads in the morning. The District Department of Transportation shared the following winter driving tips from the American Automobile Association:

  • Increase your following distance an additional 8-10 seconds when on icy roads
  • Drive in a lane that has been most recently plowed.
  • Do not use cruise control.
  • When driving up and down hills, pay attention to how other vehicles are reacting and maintain a safe distance.
  • Steer and brake with smooth and precise movements.
  • Take extra care when driving over shaded spots, bridges, and overpasses.
