Forests cover 24 percent of Oklahoma and prairie grasslands composed of shortgrass, mixed-grass, and tallgrass prairie, harbor expansive ecosystems in the state's central and western portions, although cropland has largely replaced native grasses. Where rainfall is sparse in the western regions of the state, shortgrass prairie and shrublands are the most prominent ecosystems, though pinyon pines, red cedar (junipers), and ponderosa pines grow near rivers and creek beds in the far western reaches of the panhandle. Southwestern Oklahoma contains many rare, disjunct species including sugar maple, bigtooth maple, nolina and southern live oak.

Oklahoma is located in a humid subtropical region. Oklahoma lies in a transition zone between humid continental climate to the north, semi-arid climate to the west, and humid subtropical climate in the central, south and eastern portions of the state. Most of the state lies in an area known as Tornado Alley characterized by frequent interaction between cold, dry air from Canada, warm to hot, dry air from Mexico and the Southwestern U.S., and warm, moist air from the Gulf of Mexico. The interactions between these three contrasting air currents produces severe weather (severe thunderstorms, damaging thunderstorm winds, large hail and tornadoes) with a frequency virtually unseen anywhere else on planet Earth. An average 62 tornadoes strike the state per year—one of the highest rates in the world.

Because of Oklahoma's position between zones of differing prevailing temperature and winds, weather patterns within the state can vary widely over relatively short distances and can change drastically in a short time. 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 Arctic cold front of unprecedented intensity slammed across the state, causing the temperature to crash 66 degrees, down 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 date. This type of phenomenon is also responsible for many of the tornadoes in the area, such as the 1912 Oklahoma tornado outbreak, when a warm front traveled along a stalled cold front, resulting in an average of about one tornado per hour over the course of a day.

The humid subtropical climate (Koppen Cfa) of central, southern and eastern Oklahoma is influenced heavily by southerly winds bringing moisture from the Gulf of Mexico. Traveling westward, the climate transitions progressively toward 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. Precipitation and temperatures decline from east to west accordingly, with areas in the southeast averaging an annual temperature of 62 °F (17 °C) and an annual rainfall of generally over 40 inches (1,020 mm) and up to 56 inches (1,420 mm), while areas of the (higher-elevation) panhandle average 58 °F (14 °C), with an annual rainfall under 17 inches (430 mm).

Over almost all of Oklahoma, winter is the driest season. Average monthly precipitation increases dramatically in the spring to a peak in May, the wettest month over most of the state, with its frequent and not uncommonly severe thunderstorm activity. Early June can still be wet, but most years see a marked decrease in rainfall during June and early July. Mid-summer (July and August) represents a secondary dry season over much of Oklahoma, with long stretches of hot weather with only sporadic thunderstorm activity not uncommon many years. Severe drought is common in the hottest summers, such as those of 1934, 1954, 1980 and 2011, all of which featured weeks on end of virtual rainlessness and high temperatures well over 100 °F (38 °C). Average precipitation rises again from September to mid-October, representing a secondary wetter season, then declines from late October through December.

Evidence exists that native peoples traveled through Oklahoma as early as the last ice age. Ancestors of the Wichita and Caddo lived in what is now Oklahoma. The Panhandle culture peoples were precontact residents of the panhandle region. The westernmost center of the Mississippian culture was Spiro Mounds, in what is now Spiro, Oklahoma, which flourished between AD 850 and 1450. Spaniard Francisco Vásquez de Coronado traveled through the state in 1541, but French explorers claimed the area in the 1700s and it remained under French rule until 1803, when all the French territory west of the Mississippi River was purchased by the United States in the Louisiana Purchase.

The new state became a focal point for the emerging oil industry, as discoveries of oil pools prompted towns to grow rapidly in population and wealth. Tulsa eventually became known as the "Oil Capital of the World" for most of the 20th century and oil investments fueled much of the state's early economy. In 1927, Oklahoman businessman Cyrus Avery, known as the "Father of Route 66", began the campaign to create U.S. Route 66. Using a stretch of highway from Amarillo, Texas to Tulsa, Oklahoma to form the original portion of Highway 66, Avery spearheaded the creation of the U.S. Highway 66 Association to oversee the planning of Route 66, based in his hometown of Tulsa.

During the 1930s, parts of the state began suffering the consequences of poor farming practices, extended drought and high winds. Known as the Dust Bowl, areas of Kansas, Texas, New Mexico and northwestern Oklahoma were hampered by long periods of little rainfall and abnormally high temperatures, sending thousands of farmers into poverty and forcing them to relocate to more fertile areas of the western United States. Over a twenty-year period ending in 1950, the state saw its only historical decline in population, dropping 6.9 percent as impoverished families migrated out of the state after the Dust Bowl.

In 1995, Oklahoma City was the site of one of the most destructive acts of domestic terrorism in American history. The Oklahoma City bombing of April 19, 1995, in which Timothy McVeigh and Terry Nichols detonated an explosive outside of the Alfred P. Murrah Federal Building, killed 168 people, including 19 children. The two men were convicted of the bombing: McVeigh was sentenced to death and executed by the federal government on June 11, 2001; his partner Nichols is serving a sentence of life in prison without the possibility of parole. McVeigh's army buddy, Michael Fortier, was sentenced to 12 years in federal prison and ordered to pay a $75,000 fine for his role in the bombing plot (i.e. assisting in the sale of guns to raise funds for the bombing, and examining the Murrah Federal building as a possible target before the terrorist attack).
