Well the depth of 21" makes total sense since those are measured at 7AM daily, and that's about right for the timing of the storm. 35.5" is total snowfall for the calendar day.
And ASOS is not very good in high wind.
If you go back and look at all the climo sites for 2022 and 2015 and others youll see the same thing.
No clue why they don't use SWE from a core sample, but OceanStateWX said it, ASOS is king.
