of the Choctaw reservation bounded by Arkansas, the Arkansas River and the Poteau River. This became the site of a smuggling camp called "Coke Hill", noted mostly for its importance in cocaine smuggling. After Petitioning congress to hand over jurisdiction, the 57 acres was given to Arkansas in 1905. The 1985 US Supreme Court Case Oklahoma v. Arkansas decided the land would remain Arkansas, even though the Choctaw had not been notified or asked about the territory being handed over. Therefore, the Poteau River serves as the Oklahoma-Arkansas boundary for approximately 1 mile, reducing the Choctaw Reservation and later Oklahoma by 57 acres as established in the treaties of the early 1800s.

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 they can change drastically in a short time. On November 11, 1911, the temperature at Oklahoma City reached (the record high for that date), then a cold front of unprecedented intensity slammed across the state, causing the temperature to reach (the record low for that date) by midnight. 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 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 highs well over . Average precipitation rises again from September to mid-October, representing a secondary wetter season, then declines from late October through December.
