Question: When does it get cold in the state where Slope County is located?

full_context: Document 1: Montana: East of the divide the Missouri River, which is formed by the confluence of the Jefferson, Madison and Gallatin rivers near Three Forks, flows due north through the west-central part of the state to Great Falls. From this point, it then flows generally east through fairly flat agricultural land and the Missouri Breaks to Fort Peck reservoir. The stretch of river between Fort Benton and the Fred Robinson Bridge at the western boundary of Fort Peck Reservoir was designated a National Wild and Scenic River in 1976. The Missouri enters North Dakota near Fort Union, having drained more than half the land area of Montana (82,000 square miles (210,000 km2)). Nearly one-third of the Missouri River in Montana lies behind 10 dams: Toston, Canyon Ferry, Hauser, Holter, Black Eagle, Rainbow, Cochrane, Ryan, Morony, and Fort Peck.
Document 2: 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 3: Slope County, North Dakota: The vote to create Slope County, by partitioning the lower portion of Billings, was held on November 3, 1914. This was the final (as of 2019) alteration to that once-large Dakota county, as Bowman had been partitioned off in 1883, and Golden Valley was split off in 1910. The unorganized Slope County was not attached to another county for administrative or judicial purposes during the interregnum; on January 14, 1915 the county organization was effected. The name refers to the Missouri Slope, a geographical feature that is also a popular designation for western North Dakota, particularly the area west of the Missouri River.
Document 4: Montana: The topography of the state is roughly defined by the Continental Divide, which splits much of the state into distinct eastern and western regions. Most of Montana's 100 or more named mountain ranges are concentrated in the western half of the state, most of which is geologically and geographically part of the Northern Rocky Mountains. The Absaroka and Beartooth ranges in the south-central part of the state are technically part of the Central Rocky Mountains. The Rocky Mountain Front is a significant feature in the north-central portion of the state, and there are a number of isolated island ranges that interrupt the prairie landscape common in the central and eastern parts of the state. About 60 percent of the state is prairie, part of the northern Great Plains.
Document 5: 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 6: Crow Flies High State Recreation Area: Crow Flies High State Recreation Area is a day-use state park in Mountrail County, North Dakota, west of the community of New Town. The site provides scenic views of Lake Sakakawea. Signs describe the location's role in local history, including its significance in the explorations of Lewis and Clark. The footprint of the drowned town of Sanish, now lost below the reservoir's waves, can be seen at times of low water.
Document 7: McCulley Township, Emmons County, North Dakota: McCulley Township is a former township of Emmons County, North Dakota, United States that was located in public land survey Township 134N, Range 76W. The township disbanded on March 1, 1998, and is now part of the unorganized territories of Northeast Emmons and West Emmons. Its last recorded population before dissolving was 79 during the 1990 Census.
Document 8: 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 9: Montana: The northern section of the Divide, where the mountains give way rapidly to prairie, is part of the Rocky Mountain Front. The front is most pronounced in the Lewis Range, located primarily in Glacier National Park. Due to the configuration of mountain ranges in Glacier National Park, the Northern Divide (which begins in Alaska's Seward Peninsula) crosses this region and turns east in Montana at Triple Divide Peak. It causes the Waterton River, Belly, and Saint Mary rivers to flow north into Alberta, Canada. There they join the Saskatchewan River, which ultimately empties into Hudson Bay.
Document 10: 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 11: 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 12: 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.
Document 13: 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 14: Dakota Territory: The Territory of Dakota was an organized incorporated territory of the United States that existed from March 2, 1861, until November 2, 1889, when the final extent of the reduced territory was split and admitted to the Union as the states of North and South Dakota.
Document 15: Climate of Minnesota: Autumn weather in Minnesota is marked by the rapid decrease of severe thunderstorms, dramatic cooling, and eventually the possibility of blizzards. With summer - time heat still prevalent in the southern U.S. and colder air quickly taking hold in Canada, Minnesota can be affected by wide temperature swings in short periods of time. Because of this, the jet stream, which tends to weaken during the summer months, begins to re-strengthen. This leads to quicker changes in weather patterns and increasingly strong storm systems. As autumn moves on, these storm systems bring with them progressively colder air, eventually changing the rain over snow, generally starting in October in the northern part of the state and November in the south. From September to December the average temperature in the state falls by approximately 43 ° F (23 ° C), the largest such temperature swing within any Minnesota season.
