Mixing is obviously always a concern, and I'll be interested to see how my move from Southeast Elkridge to the far western portion of Ellicott City makes an impact. However, I didn't mix even in my old location in December 2009, the two February 2010 storms or the January 2016 storm. I mixed back in 2003 in College Park, and 1996 in the Baltimore area. Obviously, December mixing is more of a concern than later in the winter given climo, but I won't start getting concerned until Monday if the mixing is still showing up. We just don't get many storms around here, especially coastals, where we get around a foot or so of snow. Certainly nothing in recent memory that I can remember. It's either a mauling of around two feet, give or take, or not much. I guess February 2014 and January 2011 could fit the bill sorta/kinda.
