We had a 2 day 3 foot event here in 2016 (30" is close enough for me). I'd like to experience a really good LES in Buffalo. Compare it to some other events I've had the good fortune of experiencing.
FWIW - Experienced the aftermath of a 3 day 3 meter event in Sass Fee, Switzerland in... I think it was 89. Had to delay the departure of our ski bus from Frankfurt because all the roads were closed at altitude in CH due to avalanche threat. We departed Fkt around midnight, drove all night and got to the resort about 9 in the morning; only to learn the slopes were closed due to the excessive snowfall, the type of snow and the continued avalanche threat (the type of snow was key as we found out later). We heard the charges all day from the helicopters and howitzers as they initiated slides in the most avalanche prone areas.
Got up the next morning with everyone psyched for a great day of powder. Heading up the lift we saw only a few paths made by the snow cats with people on piste barely moving. Couldn't figure out what was going on until we got off the lift a the top and saw a lot of the Swiss riding the lift back down with this look of "don't even think about trying to ski" on their faces. Being a group of undeterred Americans we figured it was just them and there was no way we were going to miss 3 meters of fresh powder.
In short order we quickly figured out the Swiss were indeed the smart ones. The sun from the day before had put a nice thick crust on top of the snow. So much so once you got on top of the crust, you were sliding out of control until something slowed your decent, like a fall. When you broke through the crust the underlying snow was so light it was like depth hoar. There was almost no substance to it. People who fell took 15 mins or more to just get oriented vertical again, if they could do so on their own. People without powder straps on their skis were in real trouble if their bindings released. I was on telemark skis, which don't release, so that was a big advantage.
After about 2 hours of it, many of those in our group and around us had long lost the sense of humor in it. In some cases, people were freaking out. The ski patrol initiated a rescue operation with the snow cats in areas where they could go. In many areas, the light snow made the steeper areas inaccessible even to the snow cats.
We finally made it down to the next ski lift station and rode the lifts back down to town. We don't get that kind of light stuff here and heard later from the locals that storm was a fluke.
Japan gets some whopper snowfalls. If you get a chance to experience one, think you'll be impressed.
