The height of the storm will be Friday night through Saturday, according to the National Weather Service, which says heavy snow combined with wind gusts between 20 to 55 mph may make visibility impossible.

Once it starts, the snow will fall quickly, so Maryland State Police asked drivers Friday afternoon to get off the roads before it begins.
