The other thing that I wouldn't have guessed was how localized the precipitation can be in an upslope. If the low pressure system gets parked, a small strip of the front range can just get nailed with snow and areas just a few miles away will get nothing. A few years back, one of the faster-moving hurricanes plowed through South Carolina and wound up creating an upslope in the Appalachians in North Carolina.

This is my first winter in CO and I heard a lot of people talk about the upslope storms and how they just dump snow along the front range. I experienced my first one on 3/26/09, which left 14-18" in Boulder. Then a few days later on 4/1 we got 4" of snow. Now they're forecasting another foot overnight tonight (4/3)! I love the snow, but I'm kind of bummed that this is happening now instead of 2-3 months ago. BTW - Not to be a douche, but sublimation refers to a solid transitioning to a gas, not the other way around. You mean to say precipitate, which refers to a solid forming out of a liquid/gas phase (i.e. snow). Trust me, I'm a doctor (but not the kind that helps people! ;).
