In a year when snow in the valleys has definitely been absent, how is it that some local ski resorts are dealing with less-than-stellar snowfall amounts, while others are getting more of the fresh powder? I’ve written numerous articles explaining how snow amounts can very widely across short distances. A location’s proximity to mountains, its elevation, and its tendency to get caught under the occasional small-scale snow bursts, all affect how much snow is seen. As a general rule, higher elevations will see more snow due to the colder temperatures. A city will also see more snow (relatively speaking) the closer it is to the windward side of a mountain. The sharp rise of the terrain, which forces air upward, aids the formation of precipitation (assuming there is enough moisture). Looking at several of the local ski resorts, Silver Mountain, Lookout Pass, Schweitzer Mountain, 49 Degrees North, and Mount Spokane, there is another factor to consider, when we see one location enjoying a lot more snow than another. The orientation of a mountain range and the prevailing winds in that area, have a lot to do with why some ski resorts are getting the benefit of more snow this year. Last winter, it was the “westerlies” which prevailed, meaning winds that generally blew from west to east. This particular wind pattern gave the edge, when it came to snowfall, to the Northern Rockies, a north/south oriented mountain range. Westerly winds hitting the mountain range in a perpendicular fashion, would be quickly forced upward, squeezing out all the available moisture.
