Thanks for the reply. That would make sense. I also tend to ignore the holes (and always did when I lived in Charlotte, Cary, Wilmington, and Wilkesboro), but those holes actually seem to happen here for pretty much every storm from any direction --albeit less so for these southern storms. No matter whether it's a line of thunderstorms or snow, there always seems to be a 5-10-mile wide swath across central Caldwell that receives far less precip than the surrounding areas. The last time it didn't happen that I can recall was 1993. It's an odd thing, for sure.
