Philly annual snowfall is 22 and Dulles annual snowfall is 22 and bwi is around 20. I don’t understand why everyone says it doesn’snow around here Nyc was around 25 which isn’t much more and I would say they’ve had a historic run the last two decades and that has started to skew their average. Yes many years are not snowy but the same holds true in philly and nyc snow records. That’s how averages work but people can be justified in being disappointed in a snowless winter with a mean around 22 inches. Yes, we’re not Rochester but we can expect snow.
