Climate and Geography
The Tri-Cities are in a semi-arid climate, receiving an average of 5 to 7 inches (130 to 180 mm) of precipitation every year. Winds periodically exceed 30 mph (48 km/h) when Chinook wind conditions exist. While there are an average 300 clear days every year, these are mainly between April 1 and November 1. Temperatures range from as low as 0 °F (−18 °C) in the winter to as high as 110 °F (43 °C) in the summer, and even reached 115 °F (46 °C) in July 2006. The region receives occasional snow most years but has received as much as 20 inches. Due to the semi-arid climate and subsequent large amounts of sand, a perpetual annoyance to residents is the amount of dust blown about by the frequent winds. Thanks to the aforementioned rivers, a large amount of cheap irrigation is available.
Washington is the most northwest of the lower 48 states—consequently, the area is in the Pacific Standard Time Zone. The Tri-Cities makes up the largest metropolitan area in the southeastern quadrant of Washington. The large Cascade Mountain Range to the west contributes to the semi-arid climate, which is far drier than the famously wet western side of the state. See rain shadow for more information on this phenomenon. The region's climate results in a shrub-steppe ecosystem which has 18 endemic plant species. Just west of Richland, the Fitzner/Eberhardt Arid Lands Ecology Reserve was established to study the unique plants and animals found in the local shrub steppe ecosystem. It is the largest tract of shrub-steppe ecosystem remaining in the U.S. state of Washington.

Famous quotes containing the words climate and/or geography:
“When we consider how much climate contributes to the happiness of our condition, by the fine sensation it excites, and the productions it is the parent of, we have reason to value highly the accident of birth in such a one as that of Virginia.”
—Thomas Jefferson (1743–1826)
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
