Meteorological synopsis

Unusually warm weather surged into the Eastern United States on March 12. A jet stream dip, as well as the presence of a southeastward-moving surface low pressure system that had formed over Montana on March 12 led to creation of widespread strong to severe thunderstorms throughout the region along an unusual eastward moving warm front and dryline on March 13. Starting in Central Plains, this area of severe and tornadic thunderstorms pushed eastward, producing damaging winds, large hail, and tornadoes to a total of 16 states before the low, which had turned northeastward, moved into Wisconsin and was replaced by a surface anti-cyclone on March 15.[3][4]

It moved northeast, striking the joint rural community of Allison and Sylamore along the White River and inflicting moderate damage.

This narrow but long-tracked, intense F3 tornado touched down southeast of Bailey in Nash County and moved southeast, damaging five homes and 10 other buildings with seven families being affected.[39] As it moved into Wilson County west-southwest of Sims, it turned east and strengthened as it moved towards the northern side of Wilson. It then struck several neighborhoods there, causing heavy damage, especially on east side of the area where it reached its peak strength. A total of 16 homes were severely damaged, a school sustained so much damage ($30,000) that it was forced to close, one person was injured and 16 families were impacted. Local officials stated that it was the worst storm to hit the area since 1929. Moving east, the tornado exited Wilson into rural areas of Wilson County damaging mostly farmlands. It then moved through the rural community of Wilbanks, damaging the homes in the area.[40] The tornado then began to weaken as it moved into Edgecombe County and directly into Macclesfield, causing severe damage. The tornado then moved into Crisp, causing some additional damage before dissipating east of town. Damage along this final portion included the destruction of a home and another building with damage being inflicted to three other homes and four families were affected as well.[3][41]

The tornado was on the ground for at least 50 minutes, traveled 30.1 miles (48.4 km), was 27 yards (25 m) wide, and caused $250,060 (1953 USD) in damage, with $70,000 coming from Wilson alone. It caused no fatalities, but did injure one person.[3][39][40][41] Grazulis classified this tornado as an F2.[13]

Non-tornadic impacts

On March 12, small, but abundant ¹⁄₄ in (0.64 cm) hail caused heavy damage to planes at the Little Rock Municipal Airport while also damaging a commercial greenhouse. The next day, Oklahoma was pelted by numerous severe thunderstorms that produced considerable hail and wind damage across mainly the southern and eastern portions of the state. In Elmer many roofs and windows were damaged, a barn was blown down, and the roof of an abandoned school was blown off. Even worst damage occurred in Lawton, where high winds and 1–2-inch-diameter (2.5–5.1 cm) hail damaged every roof, broke many windows, and dented many vehicles in town while nearby Fort Sill saw extensive damage to airplanes and buildings. Losses in the area alone was estimated at $2 million (1953 USD). The town of Red Oak also suffered heavy wind damage while multiple roads and bridges in the area were washed out by heavy rainfall as well. On the cold side of the system, heavy snow caused a man to die of exposure after he got lost near Esterbrook, Wyoming.

The severe weather outbreak in Oklahoma continued into the early-morning hours of March 14 with lightning striking and damaging church in Tulsa. By that time, the outbreak had begun to shift into Arkansas with severe thunderstorms inflicting hail damage to numerous areas Van Buren County. That afternoon, more hail damage was inflicted to roofs and neon signs in Harrisburg. Widespread hail and wind damage also occurred across Illinois and Missouri while a tenant home in the Lepanto-Rivervale, Arkansas area was destroyed by strong winds. That night, a thundersquall caused some wind damage in Jefferson Parish, Louisiana while a barn with stored grain in Boone Township, Indiana was destroyed by high winds as well, although a tornado may have been involved. On the south side of Wayne, Arkansas, a severe storm also caused wind damage to a drive-in theatre and hail damage to several car.

Early on March 15, a lightning strike sparked a fire that destroyed a barn and stored crops and killed livestock near Granville, Ohio. That night in Fort Meade, Maryland, lightning struck a home, damaging two rooms, with the family of four inside being treated for shock. Later, another severe storm in Hopewell, Virginia partially ripped the roof off of a radio station, buckled rafters at a partially constructed church, which also saw its basement roof crack open, damaged nearly 100 homes damaged, caused minor power failures, and uprooted trees. Farther north, a glaze of ice due to freezing rain disrupted 63 long-distance phone circuits in North-Central Wisconsin.[3]

Notes

1. An outbreak is generally defined as a group of at least six tornadoes (the number sometimes varies slightly according to local climatology) with no more than a six-hour gap between individual tornadoes. An outbreak sequence, prior to (after) the start of modern records in 1950, is defined as a period of no more than two (one) consecutive days without at least one significant (F2 or stronger) tornado.[2]
2. All dates are based on the local time zone where the tornado touched down; however, all times are in Coordinated Universal Time and dates are split at midnight CST/CDT for consistency.
3. Prior to 1994, only the average widths of tornado paths were officially listed.[5]
4. The CDNS report says the tornado traveled 18 miles (29 km) and was 500 yards (460 m) wide).[3]
