I have not recently chimed in on the snowfall discussion, but I think that we may be comparing apples and oranges here. The snowfall data like that reported at the Burlington, VT, NOAA site are from hourly measurements in a large calibrated can with flaps around the top edge that are then summed for daily, weekly, monthly, and annual totals. The hourly snow catch is then melted down for measurement of snow water equivalent (SWE) that allows calculation of snow density, especially useful for mixed precipitation events. The Mount Washington Observatory makes the same hourly measurements, although the snow catch in their can near the deck is subject to strong winds that blow some unknown percentage of the snowfall into the ravines, despite these cans having flaps around the top edge whose purpose is to dampen the wind flow across the top of the can.
For convenience, ski areas report snow depth accumulation based on stake measurements in shielded locations from the wind but not shielded by overhanging conifer limbs, which is tricky to get right. The USFS and MWAC make their snow depth measurements from a stake near the leach field downslope from their cabin in Tuckerman Ravine, an open area surrounded by trees that create a partial wind break.
Theoretically, snow stake cumulative measurements will be less than hourly measurements in cans because of settling of the snowpack even over short time increments during a storm (apples and oranges).
At the USFS Hubbard Brook Experimental Forest (HBEF) in West Thornton, N.H. (where acid rain was first discovered in the Northeast), besides the standardized snow can measurements, bi-weekly measurements are also made with a threaded T6100 aluminum snow tube, 2” in diameter, with cutting teeth at the bottom to ensure penetration into the bare ground beneath the snowpack for each measurement. These measurements require snowshoeing a course with multiple sites at different elevations and exposures (east, west, etc), a daylong adventure throughout the winter and spring. During one winter when in college, I worked at HBEF a couple days per week and was extremely envious of those making the snow course measurements. The snow tube was carried with a strap over one shoulder, along with a heavy-duty spring balance to weigh the tube and its snow content at each site, which allowed for a quick calculation of average snow density of the snowpack (i.e., the snow samples were not melted down to determine SWE).
Just more to keep in mind when comparing snowfall measurements between ski areas and NOAA sites.
Edit: Just talking over lunch today with a friend who was on ski patrol for a couple decades at Loon Mountain where they measured the snow depth at a stake in a sheltered spot twice per day, early morning and late afternoon.
