A Winter Weather Advisory is in effect for the entire viewing area as a mix of snow, sleet and freezing rain is expected throughout the early evening.

The bulk of precipitation is expected to fall between now and 8 p.m.

As of 2 p.m., multiple wrecks have been reported on nearly every interstate and highway.

Between 1/2 inch and 1 inch of a sleet/snow mix is expected to accumulate with a glaze of ice on top.

By 7 a.m. Friday, there were reports of sleet and freezing rain falling across the N.C. mountains from Asheville to Moravian Falls.

By 9:30 a.m., most Piedmont counties had reported seeing some snowflakes or light sleet.

Although the Winter Weather Advisory is slated to expire at midnight, road conditions will still be dangerous until temperatures rise above freezing.  Temperatures may not increase to above freezing until late Saturday morning.
