North American Winter
The following is a list of major snow and ice events in the United States that have caused noteworthy damage and destruction in their wake. The categories presented below are not used to measure the strength of a storm, but are rather indicators of how severely the snowfall affected the population in the storm's path. Some information such as snowfall amounts or lowest pressure may be unavailable due to a lack of documentation. Winter storms can produce both ice and snow, but are usually more notable in one of these two categories. The "Maximum accumulation" sections reflect the more notable category which is represented in inches of snow unless otherwise stated. Only category 1 and higher storms as defined by their regional snowfall index are included here. *''Note: A blizzard is defined as having sustained winds of at least 35 mph for three hours or more.''

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North Pole. Owing to Earth's axial tilt of 23.439281°, winter in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer lasts from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that affect many factors within the north coast. Such events include El Niño–Southern Oscillation. Trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents, which flow westward due to the Coriolis e ...

April 2016 North American Storm Complex
The April 2016 North American storm complex was a major storm system that resulted from an upper-level low in the United States stalling and producing record-breaking rain in and around Houston, Texas, resulting in severe flooding, as well as a major snowstorm in the Rocky Mountains. There were more than 17 inches of rain in one day in parts of the city, and up to 4 inches of rain per hour that morning at George Bush Intercontinental Airport. It is described as the wettest April in the city on record. As the most widespread flood event there since Tropical Storm Allison in 2001, it caused a state of emergency to be declared in nine counties. __TOC__ Meteorological history In mid-April 2016, a large, slow-moving upper-level low emerged from the Four Corners region in Rocky Mountains over the Central United States. Simultaneously, a ridge became anchored over the Eastern United States with another low to the east, creating an omega block—a stagnant weathe ...

1804 New England Hurricane
The 1804 New England hurricane (also known as the Storm of October 1804) was the first tropical cyclone in recorded history known to have produced snowfall. An unusual late-season storm in 1804, it yielded vast amounts of snow, rain, and powerful winds across the northeastern United States. Prior to its approach towards the East Coast of the United States, it passed through the Caribbean Sea on October 4, and later emerged near Georgetown, South Carolina. By early on October 9, a trough near the Virginia Capes turned the disturbance toward New England. Soon thereafter, the hurricane's abundant moisture clashed with an influx of cold Canadian air, leading to the deepening of the resulting pressure gradient and provoking inland intensification. While situated over Massachusetts, it attained its peak intensity of 110 mph (175 km/h), undergoing an extratropical transition. Even as it drifted towards the Canadian maritimes, consequently gradually weaken ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter Storm
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 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. Formation Winter storms are formed when moist air rises up into the atmosphere, creating low pressure near the ground and clouds up in the air. The air can also be pushed upwards by hills or large mountains. The upward motion is called lift. The moisture is collected by the wind from large bodies of water, such as a big lake or the ocean. If temperature is below freezing, , near the ground and up in the clouds, precipitation will fall as snow, ice, rain and snow mixed (sleet), ice pellets or even graupel (soft hail). Since cold air can not hold as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Great Snow Of 1717
The Great Snow of 1717 was a series of snowstorms between February 27 and March 7, 1717 (Gregorian calendar) that blanketed the colony of Virginia and the New England colonies with five or more feet (1.5 or more meters) of snow, and much higher drifts. Snowfall may have occurred elsewhere, but settler population was sparse outside of New England at that time. The Great Snow is considered one of the benchmark storms in New England, often compared to the Great Blizzard of 1888 in severity. The Great Snow, depending on the source, began on February 27 or March 1. On February 27 a typical New England nor'easter passed through, with snow falling on some areas and other places receiving a mix of snow, sleet, and rain.Zielinski and Keim, pg. 181 The first major snowstorm occurred on March 1, with another on the 4th, and a third, the worst among the three, on the 7th. At some points, the snow would lighten and stop, but the sky would remain cloudy, showing no signs of clearing. Some of t ...

2021–22 North American Winter
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
January 31 – February 3, 2021 Nor'easter
January is the first month of the year in the Julian and Gregorian calendars and is also the first of seven months to have a length of 31 days. The first day of the month is known as New Year's Day. It is, on average, the coldest month of the year within most of the Northern Hemisphere (where it is the second month of winter) and the warmest month of the year within most of the Southern Hemisphere (where it is the second month of summer). In the Southern hemisphere, January is the seasonal equivalent of July in the Northern hemisphere and vice versa. Ancient Roman observances during this month include Cervula and Juvenalia, celebrated January 1, as well as one of three Agonalia, celebrated January 9, and Carmentalia, celebrated January 11. These dates do not correspond to the modern Gregorian calendar. History January (in Latin, '' Ianuarius'') is named after Janus, the god of beginnings and transitions in Roman mythology. Traditionally, the original Roman calendar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2020–21 North American Winter
The 2020–21 North American winter was the most significant winter season to affect North America in several years, and the costliest on record, with a damage total of at least $201.845 billion (2021 USD). The season featured 6 storms ranking on the Regional Snowfall Index scale, with 4 storms ranking as at least a Category 3. Most of the winter's damage and fatalities occurred due to a February 2021 North American cold wave, historic and major cold wave in mid-February. Several other significant events occurred, including a Winter Storm Billy, crippling early-season ice storm in the Southern Plains, a December 15–17, 2020 nor'easter, powerful nor'easter in mid-December, January 31 – February 3, 2021 nor'easter, another major nor'easter in early February, two major and widespread winter storms in mid-February, and March 2021 North American blizzard, a major blizzard in the Rocky Mountains in mid-March. The winter-related events were responsible for at least 358 fatalities, maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2019–20 North American Winter
The 2019–20 North American winter was unusually warm for many parts of the United States; in many areas, neutral ENSO conditions controlled the weather patterns, resulting in the sixth-warmest winter on record, and many areas in the Northeastern United States saw one of the least snowy winters in years. In fact, Baltimore and Islip, New York, Islip saw no snow in February for the first time. Some notable events still occurred, such as a November 26 – December 3, 2019 North American blizzard, powerful blizzard that impacted the Western United States in late November, a series of cold shots in January and February, #Early February winter storm, a snowstorm within the Texas Panhandle and a #Mid-March blizzard, late-season blizzard in the High Plains. While there is no well-agreed-upon date used to indicate the start of winter in the Northern Hemisphere, there are two definitions of winter which may be used. Based on the astronomical definition, winter begins at the winter solstice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
March 2019 North American Blizzard
The March 2019 North American blizzard was a powerful Colorado Low that produced up to two feet of snow in the plains and Midwest. Rapid snowmelt following the storm caused historic flooding, and some areas received hurricane-force wind gusts. Comparable to the 1993 Storm of the Century, the storm was labeled a bomb cyclone after barometric pressure readings dropped in excess of over a 24-hour period. After the storm entered Colorado from its origination in Arizona, the pressure dropped more than and rapidly intensified over the western High Plains. The severe storm set new all-time record low barometric pressure readings in Colorado, Kansas and New Mexico. The storm itself killed only one person in Colorado, but flooding caused by the storm killed at least 3, one in Iowa and at least two in Nebraska and left ~140,000 without power in Texas. Meteorological history The system originated from an extratropical low that developed in the Gulf of Alaska on March 8. Over the next two ...

2018–19 North American Winter
The 2018–19 North American winter was unusually cold within the Northern United States, with frigid temperatures being recorded within the middle of the season. Several notable events occurred, such as a rare snow in the Southeast in December, a strong cold wave and several major winter storms in the Midwest, and upper Northeast and much of Canada in late January and early February, record snowstorms in the Southwest in late February, deadly tornado outbreaks in the Southeast and a historic mid-April blizzard in the Midwest, but the most notable event of the winter was a record-breaking bomb cyclone that affected much of the Central United States and Canada in mid-March. Unlike previous winters, a developing weak El Niño was expected to influence weather patterns across North America. Overall, however, winter of 2018–19 was mild along the mid- and lower parts of the East Coast, the West Coast, and most of the southern Plains. Overall, the meteorological winter of 2018- ...

March 1-3, 2018 Nor'easter
March is the third month of the year in both the Julian and Gregorian calendars. It is the second of seven months to have a length of 31 days. In the Northern Hemisphere, the meteorological beginning of spring occurs on the first day of March. The March equinox on the 20 or 21 marks the astronomical beginning of spring in the Northern Hemisphere and the beginning of autumn in the Southern Hemisphere, where September is the seasonal equivalent of the Northern Hemisphere's March. Origin The name of March comes from ''Martius'', the first month of the earliest Roman calendar. It was named after Mars, the Roman god of war, and an ancestor of the Roman people through his sons Romulus and Remus. His month ''Martius'' was the beginning of the season for warfare, and the festivals held in his honor during the month were mirrored by others in October, when the season for these activities came to a close. ''Martius'' remained the first month of the Roman calendar year perhaps as la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
