Question: When does it get cold in the state Northern Lights is set?

full_context: Document 1: 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 2: Climate of North Dakota: Spring is a time of major transition in North Dakota. Early spring commonly sees snowstorms, but by late spring as temperatures begin to moderate the state can experience tornado outbreaks, a risk which diminishes but does not cease through the summer and into the fall as North Dakota lies at the northern edge of Tornado Alley. Springtime flooding is a relatively common event in the Red River Valley, due to the river flowing north into Canada. The spring melt and the eventual runoff typically begins earlier in the southern part of the valley than in the northern part. The most destructive flooding in eastern North Dakota occurred in 1997, which caused extensive damage to Grand Forks.
Document 3: One man, one vote: Based on a number of inequities, the Northern Ireland Civil Rights Association was founded in 1967. It had five primary demands, and added the demand that each citizen in Northern Ireland be afforded the same number of votes for local elections (national elections followed the same eligibility rules as the rest of the UK). The slogan ``one man, one vote ''became a rallying cry for this campaign. The Parliament of Northern Ireland voted to update the voting rules, which were implemented for the Northern Ireland general election, 1969.
Document 4: North Dakota: North Dakota is in the U.S. region known as the Great Plains. The state shares the Red River of the North with Minnesota to the east. South Dakota is to the south, Montana is to the west, and the Canadian provinces of Saskatchewan and Manitoba are to the north. North Dakota is situated near the middle of North America with a stone marker in Rugby, North Dakota marking the ``Geographic Center of the North American Continent ''. With an area of 70,762 square miles (183,273 km), North Dakota is the 19th largest state.
Document 5: Northern Lights (1978 film): Northern Lights is a 1978 independent film which dramatizes the founding of the Nonpartisan League in North Dakota, a Populist political movement which took place in the American Midwest in the early 1900s.
Document 6: Climate of North Dakota: Autumn weather in North Dakota is largely the reverse of spring weather. The jet stream, which tends to weaken in summer, begins to re-strengthen, leading to a quicker changing of weather patterns and an increased variability of temperatures. By late October and November these storm systems become strong enough to form major winter storms. Fall and spring are the windiest times of the year in North Dakota.
Document 7: Northwestern University: Politics & Policy was founded at Northwestern and is dedicated to the analysis of current events and public policy. Begun in 2010 by students in the Weinberg College of Arts and Sciences, School of Communication, and Medill School of Journalism, the organization reaches students on more than 250 college campuses around the world. Run entirely by undergraduates, Politics & Policy publishes several times a week with material ranging from short summaries of events to extended research pieces.

Document 8: Northern Lights (1978 film): The film was produced, directed, written and edited by John Hanson and Rob Nilsson, and starred Joe Spano, Robert Behling, Susan Lynch and Michel Wagner. It was filmed on location in North Dakota, during the fall and winter of 1977, and utilized many locals as extras.
Document 9: Climate of North Dakota: Being 1,000 miles (1,609 km) from any large body of water (with the exception of Lake Superior), temperatures and precipitation in North Dakota can vary widely. North Dakota is far enough north to experience − 60 ° F (− 51 ° C) temperatures and blizzards during the winter months, but far enough south to experience 121 ° F (49 ° C) temperatures and tornado outbreaks in the summer. The 181 ° F degree (100 ° C) variation between North Dakota's highest and lowest temperature is the 3rd largest variation of any U.S. State, and the largest of any non-mountainous state.
Document 10: Abraham Lincoln: Prior to the Republican convention, the Lincoln campaign began cultivating a nationwide youth organization, the Wide Awakes, which it used to generate popular support throughout the country to spearhead voter registration drives, thinking that new voters and young voters tended to embrace new parties. Lincoln's ideas of abolishing slavery grew, drawing more supporters. People of the Northern states knew the Southern states would vote against Lincoln and rallied supporters for Lincoln.As Douglas and the other candidates campaigned, Lincoln was the only one to give no speeches. Instead, he relied on the enthusiasm of the Republican Party. The party did the leg work that produced majorities across the North, and produced an abundance of campaign posters, leaflets, and newspaper editorials. Thousands of Republican speakers focused first on the party platform, and second on Lincoln's life story, emphasizing his childhood poverty. The goal was to demonstrate the superior power of "free labor", whereby a common farm boy could work his way to the top by his own efforts. The Republican Party's production of campaign literature dwarfed the combined opposition; a Chicago Tribune writer produced a pamphlet that detailed Lincoln's life, and sold 100,000–200,000 copies.
Document 11: 51st state: The Philippines has had small grassroots movements for U.S. statehood. Originally part of the platform of the Progressive Party, then known as the Federalista Party, the party dropped it in 1907, which coincided with the name change. As recently as 2004, the concept of the Philippines becoming a U.S. state has been part of a political platform in the Philippines. Supporters of this movement include Filipinos who believe that the quality of life in the Philippines would be higher and that there would be less poverty there if the Philippines were an American state or territory. Supporters also include Filipinos that had fought as members of the United States Armed Forces in various wars during the Commonwealth period.
Document 12: Minneapolis: The city experiences a full range of precipitation and related weather events, including snow, sleet, ice, rain, thunderstorms, and fog. The highest recorded temperature was 108 °F (42 °C) in July 1936 while the lowest was −41 °F (−41 °C) in January 1888. The snowiest winter on record was 1983–84, when 98.6 inches (250 cm) of snow fell, and the least snowy winter was 1890-91, when only 11.1 inches (28 cm) fell.
Document 13: Galicia (Spain): In the early 20th century came another turn toward nationalist politics with Solidaridad Gallega (1907–1912) modeled on Solidaritat Catalana in Catalonia. Solidaridad Gallega failed, but in 1916 Irmandades da Fala (Brotherhood of the Language) developed first as a cultural association but soon as a full-blown nationalist movement. Vicente Risco and Ramón Otero Pedrayo were outstanding cultural figures of this movement, and the magazine Nós ('Us'), founded 1920, its most notable cultural institution, Lois Peña Novo the outstanding political figure.
Document 14: 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.
