NC native (SE Rowan County) currently live in the Roberta Mill area of Cabarrus County.( 1 mile S of 85 as the crow flies). Keep in mind many of these maps show sharp cut off over Mecklenburg County and the CLT metro as a whole. S.Meck is heavily populated (over 650,000 people S of uptown) Plus York Co (Rock Hill) has almost 300,000 people.)
That to say, any shift of the snow south, even 10 miles, will make a huge difference where snow trucks, brime, sand, etc are allocated. BUT, as most of you know this is how Winter weather works in the Carolinas.
