Special Weather Statement issued February 25 at 12:56AM EST by NWS Mount Holly NJ

With temperatures falling into the 20s, any runoff or standing water from melting snow will freeze, resulting in patchy black ice, especially on untreated roadways. Black ice is difficult to see and makes roads very slippery. In addition, light snow will develop late early this morning, and an inch of snow or less may accumulate by or just after sunrise. This, combined with the black ice, may impact the morning commute today. Slow down and give yourself extra time to travel this morning.
