A blizzard is a severe snowstorm characterized by strong sustained winds and low visibility, lasting for a prolonged period of time—typically at least three or four hours. A ground blizzard is a weather condition where snow is not falling but loose snow on the ground is lifted and blown by strong winds. Blizzards can have an immense size and usually stretch to hundreds or thousands of kilometres.
A winter storm is an event in which wind coincides with varieties of precipitation that only occur at freezing temperatures, such as snow, mixed snow and rain, or freezing rain. In temperate continental and subarctic climates, these storms are not necessarily restricted to the winter season, but may occur in the late autumn and early spring as well. A snowstorm with strong winds and other conditions meeting certain criteria is called a blizzard.
The Armistice Day Blizzard took place in the Midwest region of the United States on November 11 and November 12, 1940. The intense early-season "panhandle hook" winter storm cut a 1,000-mile-wide (1600 km) swath through the middle of the country from Kansas to Michigan.
The Schoolhouse Blizzard, also known as the Schoolchildren's Blizzard, School Children's Blizzard, or Children's Blizzard, hit the U.S. Great Plains on January 12, 1888. With an estimated 235 deaths, it is the world's 10th deadliest winter storm on record.
The 1993 Storm of the Century was a cyclonic storm that formed over the Gulf of Mexico on March 12, 1993. The cold weather, heavy snowfall, high winds and storm surges that the storm brought affected a very large area; at its height, it stretched from Canada to Honduras. The cyclone moved through the Gulf of Mexico and then through the eastern United States before moving on to eastern Canada. It eventually dissipated in the North Atlantic Ocean on March 15.
The Great Blizzard of 1899, also known as the Great Arctic Outbreak of 1899 and the St. Valentine's Day Blizzard, was an exceptionally severe winter weather event that affected most of the United States, particularly east of the Rocky Mountains. On February 11, Swift Current in present-day Saskatchewan reported a record-high barometric pressure of 31.42 inches of mercury (1,064 mb). While there was heavy snow during this event, the 1899 storm was most noted for the record cold it brought to several areas of the USA, including the first below zero (F) temperature ever recorded in Florida (Tallahassee in extreme northwest Florida recorded - 2 F.
A cold wave is a weather phenomenon that is distinguished by a cooling of the air. Specifically, as used by the U.S. National Weather Service, a cold wave is a rapid fall in temperature within a 24-hour period requiring substantially increased protection to agriculture, industry, commerce, and social activities. The precise criteria for a cold wave are the rate at which the temperature falls, and the minimum to which it falls. This minimum temperature is dependent on the geographical region and time of year.
The Early Winter 2006 North American storm complex was a severe winter storm that occurred on November 26, 2006, and continued into December 1. It affected much of North America in some form, producing various kinds of severe weather including a major ice storm, blizzard conditions, high winds, extreme cold, a serial derecho and some tornadoes.
North Dakota's climate is typical of a continental climate with cold winters and warm-hot summers. The state's location in the Upper Midwest allows it to experience some of the widest variety of weather in the United States, and each of the four seasons has its own distinct characteristics. The eastern half of the state has a humid continental climate with warm to hot, somewhat humid summers and cold, windy winters, while the western half has a semi-arid climate with less precipitation and less humidity but similar temperature profiles. The areas east of the Missouri River get slightly colder winters, while those west of the stream get higher summer daytime temperatures. In general, the diurnal temperature difference is prone to be more significant in the west due to higher elevation and less humidity.
The January–March 2014 North American cold wave was an extreme weather event that extended through the late winter months of the 2013–2014 winter season, and was also part of an unusually cold winter affecting parts of Canada and parts of the north-central and northeastern United States. The event occurred in early 2014 and was caused by a southward shift of the North Polar Vortex. Record-low temperatures also extended well into March.
The 2013–14 North American winter was one of the most significant for the United States, due in part to the breakdown of the polar vortex in November 2013, which allowed very cold air to travel down into the United States, leading to an extended period of very cold temperatures. The pattern continued mostly uninterrupted throughout the winter and numerous significant winter storms affected the Eastern United States, with the most notable one being a powerful winter storm that dumped ice and snow in the Southeastern United States and the Northeastern United States in mid-February. Most of the cold weather abated by the end of March, though a few winter storms did affect the Western United States towards the end of the winter.
The January 1886 blizzard in North America was caused by a strong extratropical cyclone which initially dropped southeast across Texas before strengthening while it moved through the South and East, near the Eastern Seaboard through New England. The cyclone was at its strongest as it moved by New Jersey. This system formed within an active pattern which brought significant snow to the southern Rockies over many days. The system brought high winds and snowfall near and west of its path, resulting in blizzard conditions across portions of the Plains and East. A significant cold spell was ushered in by this system across portions of the southern and eastern United States. A slightly stronger storm on January 3, 1913, broke January low sea level pressure records originally set by this storm.
The 2015–16 North American winter was not as frigid across North America and the United States as compared to the 2013–14 and 2014–15 winters. This was mainly due to a strong El Niño, which caused generally warmer-than-average conditions. However, despite the warmth, significant weather systems still occurred, including a snowstorm and flash flooding in Texas at the end of December and a large tornado outbreak at the end of February. The main event of the winter season, by far and large, was when a crippling and historic blizzard struck the Northeastern United States in late January, dumping up to 3 feet of snow in and around the metropolitan areas. Several other smaller snow events affected the Northeast as well, but for the most part the heaviest snowstorms and ice stayed out further west, such as a severe blizzard in western Texas in late December, and a major late-season snowstorm in Colorado in mid-April.
The February 14–15, 2015 North American blizzard was a potent blizzard that occurred in the Northeast United States. The storm dropped up to 25 inches (64 cm) of snow in the regions already hit hard with snow from the past 2 weeks. The storm system also brought some of the most coldest temperatures to the Northeast in its wake. The Blizzard was Dubbed Winter Storm Neptune by the Weather Channel.
The January 2–4, 2014 North American blizzard was a major winter storm that affected much of the East Coast with snow, and frigid temperatures following the storm. The storm had dumped up to 2 ft (0.61 m) of snow in some areas, especially around Boston, Massachusetts.
The 2010–11 North American winter was influenced by an ongoing La Niña, seeing winter storms and very cold temperatures affect a large portion of the Continental United States, even as far south as the Texas Panhandle. Notable events included a major blizzard that struck the Northeastern United States in late December with up to 2 feet (24 in) of snowfall and a significant tornado outbreak on New Year's Eve in the Southern United States. By far the most notable event was a historic blizzard that impacted areas from Oklahoma to Michigan in early February. The blizzard broke numerous snowfall records, and was one of the few winter storms to rank as a Category 5 on the Regional Snowfall Index. In addition, Oklahoma set a statewide low temperature record in February.
The February 2015 North American cold wave was an extreme weather event that affected most of Canada and the eastern half of the United States. Following an earlier cold wave in the winter, the period of below-average temperatures contributed to an already unusually cold winter for the Eastern U.S. Several places broke their records for their coldest February on record, while some areas came very close. The cause of the cold wave was due to the polar vortex advancing southward into the eastern parts of the U.S, and even making it as far south as the Southeast, where large snow falls are rare. By the beginning of March, although the pattern did continue for the first week, it abated and retreated near the official end of the winter.
The 2017–18 North American winter saw weather patterns across North America that were very active, erratic, and protracted, especially near the end of the season, resulting in widespread snow and cold across the continent during the winter. Significant events included rare snowfall in the South, an outbreak of frigid temperatures that affected the United States during the final week of 2017 and early weeks of January, and a series of strong nor'easters that affected the Northeastern United States during the month of March. In addition, flooding also took place during the month of February in the Central United States. Finally the winter came to a conclusion with a powerful storm system that caused a tornado outbreak and blizzard in mid-April. The most intense event, however, was an extremely powerful cyclonic blizzard that impacted the Northeastern United States in the first week of 2018. Similar to the previous winter, a La Niña was expected to influence the winter weather across North America.
From December 21 to 26, 2022, a historic extratropical cyclone created crippling winter storm conditions, including blizzards, high winds, snowfall, and record cold temperatures across the majority of the United States and parts of Canada. Areas which experienced blizzard conditions included parts of Minnesota, Iowa, Wisconsin, Michigan, Ohio, Pennsylvania, New York and Ontario, with the Buffalo area of New York and the Fort Erie and Kingston areas of Ontario experiencing almost two full days of blizzard/zero-visibility conditions starting from December 23. The cold wave affected all U.S. states from Colorado to the Eastern Seaboard, with effects felt as far south as Miami, Florida. On December 24, 110 million people across 36 states were subject to wind chill alerts.
January 2024 North American winter storm can refer to any of the five storms that affected North America in a two-week time period in January 2024.
