I'm glad I lived in Bethesda in Jan 2019...got shellacked by that ull (2nd part) of the storm...had at least 8" from that one. Not sure how Frederick fared between 2016 and 2021, but I don't think I've actually received 6" since I moved here. Was looking at previous pics and measured 5.5" from that early Jan 2022 event (so maybe 6 with a snowboard), but less than 6 with compaction.
