The April 2018 North American storm complex brought a wide swath of severe and winter weather that affected much of Midwest across to the East Coast of the United States. This particular outbreak led to at least 73 confirmed tornadoes over a three-day period, most of which occurred across Arkansas and Louisiana during the evening hours of April 13. The most significant tornadoes were an EF1 that caused a fatality in Red Chute, Louisiana, early on April 14, an upper-end EF2 tornado that impacted eastern sections of Greensboro, North Carolina on April 15, causing 17 injuries, and a significant EF3 tornado that impacted areas from Lynchburg to Elon, Virginia, causing severe damage and at least 10 injuries.

The system also resulted in a record-breaking and severe blizzard across the Midwest into the Northeastern United States; killing three additional people and leaving hundreds of thousands without power. Snowfall amounts of up to 18–24 inches (46–61 cm), which are rarely seen in the month of April in the region were observed, shattering numerous records.

Meteorological synopsis

April 13–14

On April 8, the Storm Prediction Center (SPC) first introduced a risk of severe weather in their day 6 outlook, valid on April 13. The threat area included the South Plains and the Mid-South from northeastern Texas into southern Missouri, where maturing convection was expected to lead to all modes of severe weather. [3] Subsequent day 5 and day 4 forecasts maintained this area with little deviation. [4] [5] In its day 3 outlook on April 11, the SPC issued an Enhanced risk of severe weather for areas between northeastern Texas into southwestern Missouri, noting that a supercellular storm mode was likely to produce large hail, damaging winds, and a few tornadoes. [6] The Enhanced risk was later extended northward into southern Iowa on April 12, [7] and by the following morning, a Moderate risk was issued across far northeastern Texas and northwestern Louisiana onward into central Arkansas. Several tornadoes, including some strong (EF2+) ones, were expected in the highest risk area. As a result, the outlook included a 15% hatched risk area for tornadoes. [8]

An outbreak of tornadoes unfolded across the region as an expansive upper-level trough pushed into the Central United States, along with a 100kt jet streak pushing into Oklahoma and Missouri. A surface area of low pressure tracked from North-Central Kansas toward the Missouri-Iowa state border, supporting a warm front arced across southern Iowa, and a dryline extending from Kansas into Texas. Within the warm sector of the low, surface dewpoints rose to the mid 60s. A swath of 850mb winds at or above 50kt persisted underneath an elevated mixed layer, yielding an unstable environment characterized by mean-layer Convective Available Potential Energy (CAPE) of 1500–2500 J/kg. Throughout the afternoon, confluent low-level flow caused several discrete thunderstorms to form across Arkansas, [8] where the SPC had issued a Particularly Dangerous Situation (PDS) tornado watch. [9] The most significant supercell of the day developed over LeFlore County, Oklahoma and eventually progressed into Crawford County, Arkansas, where it produced a half-mile-wide EF2 tornado that caused substantial damage in and near Mountainburg. [10]

Into the evening hours of April 13, the low-level jet kept intensified across Arkansas and Louisiana, with 850mb winds topping 60kt. Meanwhile, a cold front pushed eastward and soon overtook the dryline, forcing discrete thunderstorm activity into a quasi-linear convective system. With abundant moisture and mean-layer CAPE still on the order of 1,500–2,000 J/kg, the SPC mentioned potential for swaths of damaging winds with isolated embedded tornadoes. [11] Around 05:10 UTC, an EF1 tornado was developed southwest of Shreveport, Louisiana and progressed directly into the city. It damaged billboards, trees, and hotels before entering Bossier City; there, several mobile homes were damaged and a shopping center was severely devastated. After entering Red Chute, the tornado downed a tree onto a travel trailer, causing one fatality inside. The fatality marked the only tornado-related fatality of the multi-day outbreak. [12] Into the morning hours of April 14, EF2 tornadoes impacted areas near Portland, Arkansas, [13] Carencro, Louisiana, [14] and in Meridian, Mississippi. [13]

April 15

The SPC first mentioned the threat for organized severe weather across the Southeast and Mid-Atlantic regions on April 12, noting that the main threat was expected to be damaging winds. [15] A day 3 Slight risk was outlined for central Florida northward into extreme southern Virginia the next day, [16] with an Enhanced risk of severe weather introduced across much of South Carolina and central North Carolina during the morning hours of April 15. This outlook included a 10% risk area for tornadoes. The potent upper-level trough that sparked severe weather farther west over subsequent days began to tilt in a northwest-to-southeast fashion, forcing rapid cooling aloft and geopotential height falls over a large region. The surface low progressed from Iowa into Ohio and across the Appalachian Mountains, resulting in strong low-level flow and substantial moisture return across the severe weather risk area; dewpoints in the low to mid-60s caused an unstable atmosphere that ultimately led to a quasi-linear convective system and hundreds of damaging wind reports. [17] Embedded semi-discrete supercell structures within this line produced several tornadoes, including EF2 ones that affected areas east of Gilbert, South Carolina and the eastern sections of Greensboro, North Carolina. Another strong tornado moved through the Virginia towns of Timberlake and Lynchburg before reaching EF3 strength as it destroyed several homes in Elon. [18]

Winter storm and blizzard

The larger extratropical cyclone, named Xanto by The Weather Channel, responsible for the outbreak also resulted in a record-breaking and severe winter storm and blizzard across the Midwest into the Northeastern United States, as well as neighboring Ontario and Quebec.

United States

Green Bay, Wisconsin, reported 24.2 inches (61 cm), its second-heaviest snowstorm of all time and largest ever for the month of April. In Minneapolis, Minnesota, 15.8 inches (40 cm) of snow fell, which was the largest April snowstorm on record. The storm was officially classified as a blizzard, the first to affect the Minneapolis - St. Paul metropolitan area since 2005. [109] A baseball game where the Minnesota Twins hosted the Chicago White Sox was postponed. [110] The storm contributed to a record-high 26 inches (66 cm) of snow for the month of April. Sioux Falls, South Dakota, received 13.7 inches (35 cm) of snow on April 14, making it the heaviest one-day April snow total on record in the city. Further east, a severe ice storm took place.0.625 inches (1.59 cm) of freezing rain accumulated near Midland, Michigan, and up to an inch of ice was reported in Lowville, New York, in the foothills of the Tug Hill Plateau. [111] Further east, 42nd Street–Bryant Park/Fifth Avenue station and 145th Street Station flooded, and the flash flooding in New York City also resulted in the Henry Hudson Parkway being closed down. [112] In Edison, New Jersey, flooding forced both sides of Interstate 287 to close. [113] Interstate 76 in Philadelphia also flooded. [114] The 2018 Boston Marathon was held in poor conditions due to the storm. [115]

Canada

In Ontario, a mix of snow, freezing rain, ice pellets and rain battered Toronto and the surrounding area, causing hundreds of vehicle collisions, flight cancellations, power outages and transportation delays. The CN Tower and surrounding areas in downtown Toronto were closed for several days due to falling chunks of ice after the storm. Falling ice also damaged the roof at Rogers Centre, forcing a Toronto Blue Jays game to be postponed. [116] Watch parties for both the Toronto Maple Leafs and Toronto Raptors were cancelled. [117] Freezing rain also caused problems in Ottawa, Montreal, and parts of New Brunswick. [118]

<span class="mw-page-title-main">Tornado outbreak of February 23–24, 2016</span>

An unusually prolific and very destructive late-winter tornado outbreak resulted in significant damage and numerous casualties across the southern and eastern half of the United States between February 23–24, 2016. Lasting over a day and a half, the outbreak produced a total of 61 tornadoes across eleven states, which ranked it as one of the largest February tornado outbreaks in the United States on record, with only the 2008 Super Tuesday tornado outbreak having recorded more. In addition, it was also one of the largest winter tornado outbreaks overall as well. The most significant and intense tornadoes of the event were four EF3 tornadoes that struck southeastern Louisiana, Pensacola, Florida, Evergreen, Virginia, and Tappahannock, Virginia. Tornadoes were also reported in other places like Texas, Florida, and Pennsylvania. Severe thunderstorms, hail and gusty winds were also felt in the Northeastern United States and Mid-Atlantic states on February 24 as well.

<span class="mw-page-title-main">Tornado outbreak and floods of April 28 – May 1, 2017</span>

The tornado outbreak and floods of April 28 – May 1, 2017 were a series of severe weather events that affected the central United States, producing life-threatening flooding and a major tornado outbreak. It formed out of a disturbance in the Southwestern United States on April 28, and caused significant impacts, including a heavy snowstorm in the Rockies, and other types of severe weather. Up to 3 feet (36 in) of snow fell on the cold side of the system, and up to a foot of rain fell in and around the central parts of the nation.

<span class="mw-page-title-main">Tornado outbreak of April 13–15, 2019</span> Severe weather effect in the Southeastern United States

A significant severe weather and tornado outbreak affected multiple regions of the Eastern United States in mid-April 2019. Over the course of 40 hours, 75 tornadoes touched down. The outbreak produced numerous strong tornadoes throughout portions of the Deep South, while additional significant tornadoes occurred as far north as Ohio, Pennsylvania, and Delaware. The most significant tornado of the event was a long-tracked, high-end EF3 tornado that struck Alto, Texas and killed two people. Numerous weak tornadoes were also confirmed, along with numerous reports of hail and damaging straight line winds.

<span class="mw-page-title-main">Tornado outbreak of January 10–11, 2020</span> American severe weather outbreak

The tornado outbreak of January 10–11, 2020 was a two-day severe weather event stretching from the South-Central Plains eastward into the Southeast United States. An eastward-moving shortwave trough tracked across the continental United States through that two-day period, combining with abundant moisture, instability, and wind shear to promote the formation of a long-lived squall line. Hundreds of damaging wind reports were received, and 80 tornadoes occurred within this line, making it the third largest January tornado outbreak on record. Three tornadoes—an EF1 in eastern Texas, an EF2 in northern Louisiana, and an EF2 in western Alabama—led to a total of seven deaths, all in mobile homes. There were five other storm related deaths, including two due to icy roads in Lubbock, Texas, one due to drowning in Oklahoma, and one due to icy roads in Iowa. The system also brought a monthly record high temperature to Boston and Bridgeport. Extensive damage and several other injuries occurred as well. The severe weather event was notable in that it was forecast well in advance, with the Storm Prediction Center first highlighting the risk area a full week beforehand. Total damage from the event reached $1.1 billion according to the National Centers for Environmental Information.

<span class="mw-page-title-main">April 2022 North American storm complex</span> 2022 American storm complex

The April 2022 North American storm complex affected much of the Rocky Mountains and the Midwestern United States with tornadoes, heavy snow, and gusty winds. The system in general first began impacting the Northwest on April 11, before moving eastward into the Rocky Mountains the following day. It was also responsible for producing a large severe weather outbreak of tornadoes and damaging straight-line wind in the Midwest and South while contributing to a powerful blizzard in the upper Midwest states of North and South Dakota.
