The largest trend in my local data is the lack of days with 0 degrees F or below in the winter. Used to happen at least every other winter. Now it struggles to get any less than 5 above. Greenhouse warming? Disappointing for sure.

Snow totals at each clearing of snow boards: 4:30 - 5.3 in .49 melted. 6:30 1.3 in. 11PM .6 in totals to 7.2. 430PM-obs time melted total: .60. Deer tracks on top of my lower snow board. I hope he tripped. (I actually don't clear my snow boards, but just place a new one down while the storm is in progress, and clear all of them when the storm is over.)
