Question: When was the most rainfall for the city that held Donda West's funeral?

full_context: Document 1: Kanye West: In September 2013, West was widely rebuked by human rights groups for performing in Kazakhstan at the wedding of authoritarian President Nursultan Nazarbayev's grandson. He traveled to Kazakhstan, which has one of the poorest human rights records in the world, as a personal guest of Nazarbayev. Other notable Western performers, including Sting, have previously cancelled performances in the country over human rights concerns. West was reportedly paid US$3 million for his performance. West had previously participated in cultural boycotts, joining Shakira and Rage Against The Machine in refusing to perform in Arizona after the 2010 implementation of stop and search laws directed against potential illegal aliens.
Document 2: Oklahoma City: Oklahoma City is on the I-35 Corridor and is one of the primary travel corridors into neighboring Texas and Mexico. Located in the Frontier Country region of the state, the city's northeast section lies in an ecological region known as the Cross Timbers. The city was founded during the Land Run of 1889, and grew to a population of over 10,000 within hours of its founding. The city was the scene of the April 19, 1995 bombing of the Alfred P. Murrah Federal Building, in which 168 people died. It was the deadliest terror attack in the history of the United States until the attacks of September 11, 2001, and remains the deadliest act of domestic terrorism in U.S. history.
Document 3: Oklahoma City: Oklahoma City has a very active severe weather season from March through June, especially during April and May. Being in the center of what is colloquially referred to as Tornado Alley, it is prone to especially frequent and severe tornadoes, as well as very severe hailstorms and occasional derechoes. Tornadoes have occurred in every month of the year and a secondary smaller peak also occurs during autumn, especially October. The Oklahoma City metropolitan area is one of the most tornado-prone major cities in the world, with about 150 tornadoes striking within the city limits since 1890. Since the time weather records have been kept, Oklahoma City has been struck by thirteen violent tornadoes, eleven F/EF4s and two F/EF5. On May 3, 1999 parts of southern Oklahoma City and nearby suburban communities suffered from one of the most powerful tornadoes on record, an F5 on the Fujita scale, with wind speeds estimated by radar at 318 mph (510 km/h). On May 20, 2013, far southwest Oklahoma City, along with Newcastle and Moore, was hit again by a EF5 tornado; it was 0.5 to 1.3 miles (0.80 to 2.09 km) wide and killed 23 people. Less than two weeks later, on May 31, another outbreak affected the Oklahoma City area, including an EF1 and an EF0 within the city and a tornado several miles west of the city that was 2.6 miles (4.2 km) in width, the widest tornado ever recorded.
Document 4: Kanye West: The funeral and burial for Donda West was held in Oklahoma City on November 20, 2007. West played his first concert following the funeral at The O2 in London on November 22. He dedicated a performance of "Hey Mama", as well as a cover of Journey's "Don't Stop Believin'", to his mother, and did so on all other dates of his Glow in the Dark tour.
Document 5: Kanye West: In 2008, following the death of West's mother, the foundation was rechristened "The Dr. Donda West Foundation."  The foundation ceased operations in 2011.
Document 6: Kanye West: On November 10, 2007, at approximately 7:35 pm, paramedics responding to an emergency call transported West's mother, Donda West, to the nearby Centinela Freeman Hospital in Marina del Rey, California. She was unresponsive in the emergency room, and after resuscitation attempts, doctors pronounced her dead at approximately 8:30 pm, at age 58. The Los Angeles County coroner's office said in January 2008 that West had died of heart disease while suffering "multiple post-operative factors" after plastic surgery. She had undergone liposuction and breast reduction. Beverly Hills plastic surgeon Andre Aboolian had refused to do the surgery because West had a health condition that placed her at risk for a heart attack. Aboolian referred her to an internist to investigate her cardiac issue. She never met with the doctor recommended by Aboolian and had the procedures performed by a third doctor, Jan Adams.
Document 7: Kanye West: Adams sent condolences to Donda West's family but declined to publicly discuss the procedure, citing confidentiality. West’s family, through celebrity attorney Ed McPherson, filed complaints with the Medical Board against Adams and Aboolian for violating patient confidentiality following her death. Adams had previously been under scrutiny by the medical board. He appeared on Larry King Live on November 20, 2007, but left before speaking. Two days later, he appeared again, with his attorney, stating he was there to "defend himself". He said that the recently released autopsy results "spoke for themselves". The final coroner's report January 10, 2008, concluded that Donda West died of "coronary artery disease and multiple post-operative factors due to or as a consequence of liposuction and mammoplasty".
Document 8: Oklahoma: 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.
Document 9: Oklahoma City: The city is roughly bisected by the North Canadian River (recently renamed the Oklahoma River inside city limits). The North Canadian once had sufficient flow to flood every year, wreaking destruction on surrounding areas, including the central business district and the original Oklahoma City Zoo. In the 1940s, a dam was built on the river to manage the flood control and reduced its level. In the 1990s, as part of the citywide revitalization project known as MAPS, the city built a series of low-water dams, returning water to the portion of the river flowing near downtown. The city has three large lakes: Lake Hefner and Lake Overholser, in the northwestern quarter of the city; and the largest, Lake Stanley Draper, in the sparsely populated far southeast portion of the city.
Document 10: Oklahoma: Oklahoma had 598 incorporated places in 2010, including four cities over 100,000 in population and 43 over 10,000. Two of the fifty largest cities in the United States are located in Oklahoma, Oklahoma City and Tulsa, and 65 percent of Oklahomans live within their metropolitan areas, or spheres of economic and social influence defined by the United States Census Bureau as a metropolitan statistical area. Oklahoma City, the state's capital and largest city, had the largest metropolitan area in the state in 2010, with 1,252,987 people, and the metropolitan area of Tulsa had 937,478 residents. Between 2000 and 2010, the cities that led the state in population growth were Blanchard (172.4%), Elgin (78.2%), Jenks (77.0%), Piedmont (56.7%), Bixby (56.6%), and Owasso (56.3%).
Document 11: Oklahoma City: With 19.48 inches of rainfall, May 2015 was by far Oklahoma City's record-wettest month since record keeping began in 1890. Across Oklahoma and Texas generally, there was record flooding in the latter part of the month
Document 12: Kanye West: Kanye Omari West was born on June 8, 1977 in Atlanta, Georgia. His parents divorced when he was three and he and his mother moved to Chicago, Illinois. His father, Ray West, is a former Black Panther and was one of the first black photojournalists at The Atlanta Journal-Constitution. Ray West was later a Christian counselor, and in 2006, opened the Good Water Store and Café in Lexington Park, Maryland with startup capital from his son. West's mother, Dr. Donda C. (Williams) West, was a professor of English at Clark Atlanta University, and the Chair of the English Department at Chicago State University before retiring to serve as his manager. West was raised in a middle-class background, attending Polaris High School in suburban Oak Lawn, Illinois after living in Chicago.
Document 13: Kanye West: West's life took a different direction when his mother, Donda West, died of complications from cosmetic surgery involving abdominoplasty and breast reduction in November 2007. Months later, West and fiancée Alexis Phifer ended their engagement and their long-term intermittent relationship, which had begun in 2002. The events profoundly affected West, who set off for his 2008 Glow in the Dark Tour shortly thereafter. Purportedly because his emotions could not be conveyed through rapping, West decided to sing using the voice audio processor Auto-Tune, which would become a central part of his next effort. West had previously experimented with the technology on his debut album The College Dropout for the background vocals of "Jesus Walks" and "Never Let Me Down." Recorded mostly in Honolulu, Hawaii in three weeks, West announced his fourth album, 808s & Heartbreak, at the 2008 MTV Video Music Awards, where he performed its lead single, "Love Lockdown". Music audiences were taken aback by the uncharacteristic production style and the presence of Auto-Tune, which typified the pre-release response to the record.

Document 15: Oklahoma: All of the state frequently experiences temperatures above 100 °F (38 °C) or below 0 °F (−18 °C), though below-zero temperatures are rare in south-central and southeastern Oklahoma. 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. 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. 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.
