I wouldn't count on Lake Placid/Whiteface having good conditions either. This year was highly unusual for the area.
Mammoth is in California, and pretty much suffers from the same as Tahoe.
Utah and Colorado are really the best bets. The higher elevations, allow them to make plenty of snow, and usually at that time storms are frequently hitting the area. The colder temps allow good snow to stick around longer too.
Plus, Whiteface/Placed terrain doesn't even't compare to what you have out west.
