Bars show averages over 5-year periods (last bar is a 6-year average). For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. This typically favors the windward (western) slopes of the Teton range and the upper leeward slopes on the eastern side of the range. Observations When moist air expands, it cools and condenses into precipitation, depositing heavier precipitation the more it is forced to rise. Chinook windswarm and dry downslope winds that occur along the eastern slope of the Rocky Mountainsare a hazard unique to Wyoming and western mountain states.
