That 17.7 is from 1pm. It has not stopped snowing...not to mention I'm at almost 2 feet for the whole event. In fact I'm kinda questioning the low end of that as it has snows an average of an inch an hour for about 24 of the last 36 hours. Yes there were periods of 2 to 3 inch an hour and periods of 1/4 to 1/2 inch hour. It averages out. If this band stays put and it continues to snow 30" is not a pipe dream.
