How Wyoming's Western Mountains Shape Local Temperatures

The high mountains of western Wyoming (Wind River, Teton, Absaroka ranges) create dramatic temperature effects:

• Elevation Cooling: Temperatures drop ~3.5°F per 1,000 ft; high valleys are significantly cooler than basins.
• Adiabatic Cooling: Rising air expands and cools, bringing precipitation to windward slopes.
• Rain Shadow: Leeward valleys (e.g., Jackson Hole) are drier but can trap cold air, causing extreme winter lows.
• Continental Climate Amplification: Mountains intensify seasonal swings—hot summer days in basins, frigid nights at elevation; deep winter cold pools in valleys.

Microclimates vary wildly over short distances; always check localized forecasts.
