Climate

Oklahoma is located in a temperate region and experiences occasional extremes of temperature and precipitation typical of a continental climate.[35] Most of the state lies in an area known as Tornado Alley characterized by frequent interaction between cold and warm air masses producing severe weather.[20] An average 54 tornadoes strike the state per yearone of the highest rates in the world.[36] Because of Oklahoma's position between zones of differing prevailing temperature and winds, weather patterns within the state can vary widely between relatively short distances and can change drastically in a short time.[20] As an example, on November 11, 1911, the temperature at Oklahoma City reached 83 F (28 C) in the afternoon (the record high for that date), then an incoming squall line resulted in a drop to 17 F (?8 C) at midnight (the record low for that date); thus, both the record high and record low for November 11 were set on the same day.[37] Oklahoma's climate is prime for the generation of thunderstorms. The humid subtropical climate (Koppen Cfa) of the eastern part of Oklahoma is influenced heavily by southerly winds bringing moisture from the Gulf of Mexico, but transitions progressively to a semi-arid zone (Koppen BSk) in the high plains of the Panhandle and other western areas from about Lawton westward less frequently touched by southern moisture.[35] Precipitation and temperatures fall from east to west accordingly, with are

s in the southeast averaging an annual temperature of 62 F (17 C) and an annual rainfall of 56 inches (1,420 mm), while areas of the panhandle average 58 F (14 C), with an annual rainfall under 17 inches (430 mm).[20] All of the state frequently experiences temperatures above 100 F (38 C) or below 0 F (?18 C),[35] and snowfall ranges from an average of less than 4 inches (10 cm) in the south to just over 20 inches (51 cm) on the border of Colorado in the panhandle.[20] The state is home to the Storm Prediction Center, the National Severe Storms Laboratory, and the Warning Decision Training Branch, all part of the National Weather Service and located in Norman.[38] Oklahoma's highest recorded temperature of 120 F (49 C) was recorded at Tipton on June 27, 1994 and the lowest recorded temperature of ?31 F (?35 C) was recorded at Nowata on February 10, 2011. Severe weather refers to any dangerous meteorological phenomena with the potential to cause damage, serious social disruption, or loss of human life.[1] Types of severe weather phenomena vary, depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, lightning, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal severe weather phenomena include blizzards, snowstorms, ice storms, and duststorms.
