Little Snake River, These cold waves are usually accompanied by snow, but not enough to lead to severe snow and cold conditions. Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations. Roof snow loads can vary depending on melting and Such variations have implications for water availability across the West, as snowmelt from the winter snowpack feeds many rivers and streams. The lower the humidity, the better for making snow. In the 1980s there were at least 9 statewide blizzards in Wyoming, in the 1990s there were at least 25. NDMC, n.d.: U.S. Drought Monitor.

However, Alpine often receives heavier snow than Jackson since there is a gap in the terrain that allows moisture to stream through the Snake River Valley and Palisades unobstructed. Our beach/pool temperature score is 0 for perceived temperatures below 65F, rising linearly to 9 for 75F, to 10 for 82F, falling linearly to 9 for 90F, and to 1 for 100F or hotter. snow "values" are greatly degraded due to high winds, the lower graph These numbers are obtained from theUS National Centers for Environmental Informationsrecords. Under a higher emissions pathway, historically unprecedented warming is projected during this century (Figure 1). National Oceanic and Atmospheric Administration, National Weather Service, deposited snow varies with weather conditions, however, and concurrent During the winter months, these winds can persist along the eastern slope of the Continental Divide and often bring large temperature increases that lead to rapid snowmelt. Temperatures in Wyoming have risen about 2.5F since the beginning of the 20th century (Figure 1), and nearly every year of this century has been above the long-term average. Please Contact Us.
