What seems to be happening is that with long-term changes, upper-level patterns are becoming more amplified/persistent so the big storms dig further south and east consistently. So we miss the upslope ones, which provide the most precip. I think that's the more alarming thing, since upslope storms provide the bulk of Oct-April precip east of the Divide till you get east of around 102 W. I have no met training at all, just lots of other science and good at recognizing patterns (I think).
