A series of destructive tornadoes affected the Southeastern United States on Easter Sunday and Monday, April 12–13, 2020. Several were responsible for prompting tornado emergencies, including the first one to be issued by the National Weather Service in Charleston, South Carolina. A large squall line formed and tracked through the mid-Atlantic on April 13, prompting multiple tornado warnings and watches. Fifteen total watches were produced during the course of the event, two of which were designated Particularly Dangerous Situations. With 34 tornadic fatalities reported, it was the deadliest tornado outbreak in the U.S. since the April 2014 tornado outbreak.[2]

Meteorological synopsis

For weeks throughout March and into April, an expansive area of high pressure built across the Southeast United States,[3] contributing to abnormally warm temperatures across much of the country. The United States as a whole experienced its seventeenth warmest March, continuing the pattern that persisted throughout winter. In particular, many locations along the U.S. and Mexican Gulf coasts saw record warmest temperatures for the month.[4] Calm weather associated with the high-pressure area induced rapid warming of the Gulf of Mexico waters to their highest values in the modern record—greater than 2 °C (3.6 °F) above the 1971–2010 average—as well as a moistening of the air near the surface.[3][5] Increased instability associated with anomalously warm and moist air from the Gulf of Mexico has been associated with an increased risk of severe weather and tornado activity.[6]

The first indications of organized severe weather came on April 8, when the Storm Prediction Center (SPC) outlined 15% probabilities for severe weather within 25 mi (40 km) of a point from central Texas eastward into the Florida Panhandle and eastern Georgia valid for April 11–12.[7] These threat areas were later refined with the introduction of a day-3 moderate risk, the fourth of five threat levels, across northeastern Louisiana through central Alabama on April 10.[8] Historically, the SPC issues one day-3 moderate risk every year, and half of those over the previous decade were later upgraded to High risk, the highest threat level.[9] Over subsequent days, a significant mid-level shortwave trough progressed eastward across the United States. By the pre-dawn hours of April 12, mid-level cooling associated with the feature overspread the Edwards Plateau, Hill Country, and much of central Texas. Accordingly, an intense line of severe thunderstorms developed along a dry line while vigorous convective development formed farther east.[10] These thunderstorms were initially isolated in nature but soon coalesced into a mesoscale convective system as they encountered an enhanced corridor of warm air streaming northward, as well as very strong wind shear.[11][12] This storm complex progressed across northern Louisiana through the late morning and early afternoon hours, contributing to multiple tornado debris signatures.[13] One such tornado in Monroe was rated EF3 strength.[14] In advance of the line, a lifting warm front aided in the formation of a very moist, highly unstable, and highly sheared environment across and northeastern Louisiana and much of Mississippi.[15] Accordingly, the SPC issued a particularly dangerous situation tornado watch into the late evening hours.[16]

Severe damage to a grove of trees near Livingston, South Carolina, from an EF3 tornado on the morning of April 13.

A weather balloon launch from Jackson, Mississippi, at 18:00 UTC revealed the presence of a capping inversion across the region. This cap was expected to weaken across central Mississippi,[17] while forecasters expressed more uncertainty about its longevity across southern Mississippi and Louisiana.[18] As a small area of low pressure progressed across northwestern Mississippi, it caused surface winds to turn out of the east-southeast, enhancing the potential for tornadoes. As a cluster of storms across central Mississippi progressed toward the northeast, it began to intensify and develop supercell characteristics with an attendant threat of strong tornadoes.[19] Farther south, two distinct supercells developed within an environment where long-tracked, significant tornadoes were favored, both exhibiting extremely strong rotation and distinct debris signatures.[20] Based on previous storm structures in similar environments, the SPC remarked that "this is an exceptionally rare event" and estimated tornadic winds of 170–205 mph (274–330 km/h), consistent with a tornado of EF4 or EF5 intensity.[1][21][22] After conducting damage surveys, meteorologists identified two intense tornadoes with the first supercell, one of EF3 intensity that killed three people northwest of Salem to southwest of Bassfield and an even stronger one of EF4 intensity from south of Bassfield to southwest of Pachuta.[23][24] An EF3 tornado was identified with the second supercell.[25]

Throughout the evening hours, the severe weather and tornado risk shifted eastward into Alabama, with a comma-head circulation across northern Alabama contributing to multiple confirmed tornadoes.[26] This feature continued into northwestern Georgia, maintaining its well-defined structure in spite of a marginally unstable environment.[27] An EF2 tornado carved a path from northwest of Chatsworth, Georgia to southeast of Benton, Tennessee, killing seven people. While local enhancement of storm activity occurred within an extensive line of convection in central Alabama,[28] dewpoints rose in the wake of the earlier storm complex across northern Georgia and southeastern Tennessee, further boosting instability values in the presence of extremely strong wind shear.[29] An EF3 tornado killed two people in the outskirts of Chattanooga, Tennessee.[30] The pre-frontal squall line shifted eastward into eastern Georgia and the Carolinas overnight. An EF3 tornado was confirmed south of Thomaston to northwest of Redbone in Georgia.[31] A second EF3 tornado from south-southeast of Westminster to west of Central in South Carolina killed one person.[32] Yet another EF3 from east-northeast of Elko to west-southwest of St. Matthews in South Carolina caused two more fatalities.[33] For the 24-hour period ending 12:00 UTC April 13, the National Weather Service issued 141 tornado warnings, the most in one day since the tornado outbreak of March 2–3, 2012.[34] Through the morning hours of April 13, the line of intense thunderstorms continued eastward and intensified given marginal daytime heating, a steady stream of rich moisture, and intense low-level wind shear.[35] The SPC had already outlined an Enhanced risk of severe weather along the U.S. East Coast from southeastern Georgia northward into northern Virginia.[36] Swaths of damaging winds and tornadoes were recorded throughout the day, including 12 tornadoes in North Carolina, the sixth largest one-day outbreak on record in the state going back to 1950.[37]

According to radar, debris lofted by the two tornadoes exceeded 20,000 ft (6.1 km) high and may have been carried up to 40 mi (64 km) downstream into Alabama.[74] At least twelve fatalities were confirmed, including four in Jefferson Davis County, two each in Jones and Lawrence counties, and one each in Carroll, Panola, and Walthall counties.[75] As the line of storms progressed east, another significant tornado affected Chattanooga, Tennessee, prompting yet another tornado emergency.[74] The tornado killed two people,[30] including one man who died when a tree fell onto his home; numerous other people were treated for injuries at local hospitals.[76] It has been rated EF3 intensity.[53] A pre-dawn tornado in Murray County, Georgia, killed seven people and injured at least 23 others as it hit a number of mobile homes.[47] A man in Cartersville, Georgia, was also killed when a tree fell through his home.[77] Numerous deadly tornadoes tracked across South Carolina, including one death associated with an EF3 tornado in Seneca, one death in Colleton County, five deaths in Hampton County—three of which were in Nixville—and two deaths associated with an EF3 tornado in Livingston.[75]

Non-tornadic impacts

Heavy rainfall across eastern Texas led to flash flooding and multiple road closures throughout many communities. Downed trees and powerlines caused additional road closures.[78] Gusty winds in Upshur County, Texas killed one man after a tree fell on him in his driveway.[79] As the storms progressed into Arkansas, widespread damaging winds were observed, causing the collapse of old buildings and the historic Centennial Baptist Church in downtown Helena-West Helena.[80] The 9-1-1 and emergency dispatch were disrupted throughout the city, and scattered debris obstructed ambulances from reaching hospitals.[81] The strong winds toppled numerous trees, powerlines, and fences throughout the southern portions of the state.[82] Additional damage was inflicted to structures such as greenhouses, poultry farms, sheds, barns, and docks. The downed trees blocked numerous highways.[46] In White Hall, one downed tree fell onto a home and killed an occupant. More than 143,000 customers were left without power in Arkansas in the storms' wake.[83] In Mississippi, heavy rainfall overspread Panola County, where Mississippi Emergency Management Personnel donated sandbags to prevent flooding.[84] Widespread rainfall amount of 3–4 in (76–102 mm), locally exceeded 6 in (150 mm), across northern Alabama prompted significant flooding across DeKalb County. There, about 50 roadways were temporarily closed. Floodwaters inundated some businesses in Collinsville. In nearby Fort Payne, waters inundated several businesses, forcing about 35 people from the flooded areas. Multiple roads were reportedly washed out.[85] Significant flooding was likewise reported across Madison, Morgan, and Jackson counties.[86]

Farther north in Tennessee, a 33-year-old woman was swept away and drowned by rushing water at a bridge in Kimball.[30] Four bridges in total were damaged by the flooding, including three in South Pittsburg.[87] Nashville recorded a daily rainfall record of 2.23 in (57 mm).[88] Heavy rainfall fell throughout the Tennessee Valley in the wake of the wettest first three months of any year on record, causing the Chickamauga Dam and Watts Bar Lake to climb about 1.5 ft (0.46 m) above normal summertime pool levels.[89] Numerous roads were blocked in Rutherford, Williamson,[90] and Washington counties.[91] The McFarland Park in Florence was submerged as the Tennessee River spilled its banks.[92] Across Unicoi County, multiple roads were washed out. The rising waters prompted an evacuation order for the Temple Hill community.[93] High waters flowed through homes around Hampton and Valley Forge in Carter County.[94] The Beaver Creek in Bristol overflowed its banks, flooding intersections.[95] The Kingsport Fire Department rescued 21 people as the city was threatened by rising waters.[96] A total of 27 roads were closed throughout Sullivan County.[97] In northeastern Tennessee, flooding damaged two bridges in the Johnson City area. Some residents in the community of Sinking Creek were cut off as several low-level areas were inundated. In Carter County, the Gap Creek overflowed its banks and closed roadways.[98]

A person was killed by a fallen tree in Davidson County, North Carolina.[99]

Outside the warm sector of the broad system, an unseasonable snowstorm and gale-force winds affected regions from the northern Plains into the Midwestern United States. Sioux Falls, South Dakota, recorded 5.2 in (130 mm) on April 12, a daily record and the second snowiest Easter Sunday on record.[100] The Twin Cities recorded 5.1 in (130 mm) of snow, setting a new Easter Sunday record going back to 1891.[101] Accumulations totaling to nearly a foot across portions of southern Minnesota caused multiple spinouts and crashes, principally along Interstate 35 south of the Twin Cities, Interstate 90 between Albert Lea and Rochester, and U.S. Highway 52 between Rochester and the Twin Cities. Traffic, though, was lighter than usual given the stay-at-home order for the ongoing coronavirus pandemic.[102] State patrol reported 140 crashes, 126 vehicle that spun out, and 6 semi-trucks that jackknifed on slippery roads. Fourteen people were injured.[103] In Wisconsin, a band of 6–15 in (150–380 mm) accumulations fell north of a Marshfield to Wausaukee line.[104] Daily snowfall records were set in Rochester and Eau Claire.[105][106] Winds exceeding gale threshold backed up waters on the Fox and East rivers, causing minor flooding in Green Bay.[104] In Michigan, areas of the Upper Peninsula between Marquette and Munising recorded 18–24 in (460–610 mm) of snow.[107] Wave heights of 7.5–8.5 ft (2.3–2.6 m) were estimated on Lake Michigan.[108]

Strong wind gusts in New Jersey left more than 56,000 customers without power in the state. The outage forced a Covid-19 testing site in Morris County to be closed temporarily. In Cresskill, a tree fell onto a home.[109]

Aftermath

On the night of April 12, state of emergency declarations were issued in Louisiana, Mississippi, and Alabama.[110] More than 1.3 million customers from Texas into Pennsylvania lost power at the height of the storm.[74] Widespread damage in Seneca, South Carolina, prompted a curfew for the city.[111] South Carolina Governor Henry McMaster visited Seneca on Monday to survey the damage and conduct a press conference.
