At the risk of getting too far into the weeds, or, in this case, the snowdrift, the National Weather Service uses several levels of weather watchers to record snowfall. Official climate stations:The official weather stations are typically at larger or regional airports. For Morrin’s New York office, they are at LaGuardia, John F. Kennedy, Central P...
While those who collect the data might be amateur weather buffs, the numbers they collect form the record of weather and, over time, climate. As such, these tabulations factor into federal funding and policy decisions, Morrin said. "The impacts are huge, not only for the climate community, but also for money, for FEMA reimbursements," Morrin said. ...
Where to take snowfall readings is important, Morrin said. While it's convenient to open the back door and stick the ruler into the nearest pile, that measurement could be affected by swirling snow – which could give a too-high reading – or by the heat from the building – which could give a too-low reading. For the most accurate reading, you're goi...
At those airport official climate stations, there’s a specific method for measuring snowfall. The observer places a “snowboard” – a 2-foot-by-3-foot piece of hard, white plastic – in an area that has been chosen using the criteria set forth above. Snow is measured with a ruler in tenths of an inch at several spots on that board, with any drifts or ...
The other go-to conversation starter during a storm is what kind of snow fell. In Shrub Oak, Dan Thaler measures snow depth – on a rudimentary snow gauge fashioned from an old kitchen-cabinet door, but with Morrin's approval – and the kind of snow that falls. A metal cylinder in Thaler’s back yard captures the flakes. After the storm, he heats the ...
Those who want to capture a storm's highest snow total should use their ears, Morrin said. "We get a lot of change over. You get a storm that starts, nice and fluffy snow, nice fluff factor. You start to measure pretty quick and get a couple quick inches and then, four or six hours into the storm, it changes to sleet. And it sleets for a couple of ...

Roof ventilation designs for areas of deep snow cover: here we discuss the problem of increased attic moisture, condensation, ice formation, and ice dam leaks that can occur on roofs where deep snow cover interferes with exit venting at the ridge vent.
Only for a small fraction of winter days does New York City have at least an inch of snow on the ground. Snow is most likely to accumulate during February. Typically, on four days in a winter, the snow covering Central Park amounts to ten or more inches deep.

If you have ever lived through a New York City winter, you’ll appreciate that while a bit of snow may be annoying, the puddles that accumulate on nearly every corner shortly after a snowfall are often a much greater hazard.
