The radar in Raleigh is scanning in an low upward angle. The snow over the radar site was not making it to the ground. Wnat you are seeing to the south is where it actually is snowing. To the west and to the east, the radar is picking up the snow that is not reaching the ground as the radar angle is picking up the snow echoes. I live under the N in Burlington and it was not snowing here at the time even though the radar was picking up echoes... in fact, it was only snowing in a line from Asheboro, Pittsboro, Wilson, Greenville line at the time of this radar... finally saw some here an hour later however...
