I drove to Whitefield daily last year and I can confirm that there were plenty of times when we have a foot plus and they had nothing. Literally bare ground. In fact I’ve noticed a few occasions when Littleton had significantly more snowcover. It’s a combination of lack of significant upslope, strong downslope, and poor CAD (although we are even worse on that front at the higher elevations, but we more than make it up in upslope)
