I have had extensive correpondence with 3 people involved in careful snow measuring in Vermont, all in the Stowe area. They do their jobs the same way people in the West do theirs, and I'm quite convinced that the northern Greens at ~3,000 elevation get somewhat over 300 inches per season. There is controversy about this because the independent measurements at WCAX transmitter on Mt. Mansfield (Ricardo referred to this above) look too low. The "Mansfield Stake" new snow measurements are taken from a 24-inch high canister, while the other measurements are done with a snowboard as in most of the West. Wind, riming etc. tends to result in less snow getting into the canister than onto a snowboard, plus if there's more than 24 inches in 24 hours (they checked the Valentine's Day storm of 2007) the canister isn't going to pick that up.
With regard to Jay, Vermont locals all agree it gets the most snow. Jay's numbers seemed to increase after a management change in 2000. They were quoting from an upper mountain location vs. what probably was mid-mountain before. Jay also keeps lower measurements that I get at the end of the year. If you average the post-2000 upper and lower, it looks similar to the 1982-1999 data. I take my best shot for a Nov-Apr number for each area, and with 30 years of data that comes out to 329 for Jay, which I doubt any Vermont local would find unreasonable. Marketing quoting from an upper vs. more representative mid-mountain location in not a exclusively eastern phenomenon: Jackson, Alyeska, Squaw, Heavenly and Park City do it too.
If you book ahead/have a week vacation you got rocks in your head if you don't head out west.
I agree with this but it has little to do with snowfall. It has everything to due with rain, which is a constant threat in the East and essentially unheard of in Colorado in the winter.
1) The ice that ensues after a rain/freeze event is on a completely different level of unpleasantness vs. spring melt/freeze scenarios.
2) Warmups in the East with or without rain tend to damage the snowpack more with the chronic high humidity. It is not uncommon for open terrain to lose enough cover to be closed mid-season after a rain or warm spell. Once terrain in Colorado gets open, it stays open for the whole season with extremely rare exceptions like 2012, which combined an unusually low snowpack with an abnormally warm and dry spring.
3) In the East skiing can great one week (last weekend) and awful the next (this weekend). That's why booking far in advance is dangerous. If skiing in Colorado is great one weekend, it may not be powder the next weekend, but it will be mostly packed powder with as much or more terrain open, and it will not suck. Even a month later it can still be decent with little new snow.
