At 10AM on 11 May 1970, the SELS (Severe Local Storms unit) issued an outlook that stated that isolated thunderstorms were possible in the High Plains region of West Texas, and amended the outlook at 1:25 PM to include the possibility that some of the storms may become severe. Warm and dry conditions dominated the area throughout the afternoon; the temperature peaked at a high of 90°F (32°C) with moderate humidity. At 6PM, large cumulus clouds began to appear in the area, and at 6:30 the first echoes indicating thunderstorms began to appear on radar scopes in nearby Amarillo

Conditions continued to deteriorate through the early evening, and at 7:30 the local weather bureau issued a forecast which included the developing thunderstorm activity.

The devastating twister tore through several densely populated residential areas before slicing through downtown, dealing a direct blow to the First National Bank building and the Great Plains Life building. The tornado then moved north toward the airport, where at 10:00PM, anemometer

Aftermath

The second tornado was devastating, affecting a 25 square miles (64.7 km²) area or roughly a quarter of Lubbock. Hardest hit were the inner city commercial and residential areas, the light industrial area south of Loop 289, and the residential area north of Loop 289 and the Lubbock Municipal Airport. A total of 430 homes were destroyed, 519 sustained major damage, and 7,851 more sustained minor damage. Another 600 apartments were destroyed and 549 damaged, and one hundred mobile homes were severely damaged or destroyed. The Guadalupe Neighborhood, consisting of mostly old wood frame or stucco homes, and parts of the Mesa Road area near the Lubbock Country Club, were almost completely leveled.

Since the tornado hit the downtown area, over 250 businesses were also severely damaged or destroyed, including 20 city and county offices. Every motel along 4th Street and Avenue Q north of 10th Street sustained major damage, and several motels and other businesses along Avenue Q, which is a major artery through the city, were destroyed. Several banks and warehouses were severely damaged, and one nightclub lost its entire top floor. Eight elementary schools were damaged, as well as Lubbock and Estacado High Schools, the latter losing a large portion of the roof over the gym.

 was actually twisted by the tornado, and was damaged so badly, many thought it would collapse; several radio towers on the roof were twisted or broken off. Much of the plaster in the stairwell walls between the 4th and 16th floors had cracked, and 60% of the building's windows were shattered. A foot of permanent deformation damage occurred at the steel frame on the south side, and three of the building's four elevators were damaged with the support rails bent. In spite of the severity of the damage and amid cries to demolish, the owners chose to repair it instead, and it still stands; this building is believed to be the tallest building to survive a direct hit from an F5 tornado.

In addition to damage to buildings, there was damage to other property. Over 10,000 vehicles were damaged or destroyed, and at Lubbock Municipal Airport, one hundred private aircraft and 19 military planes were destroyed. Many utilities were damaged or destroyed and 220 light poles were toppled, leaving the city's two utility companies scrambling to restore power in the days immediately following the storm.

 Company reported that 25,000 telephones were knocked out of service and 600 long distance lines were ruined. There was extensive ecological damages as well; many trees were damaged or destroyed, including the city’s aged Chinese elm trees. Mackenzie State Park, Pioneer Park, Guadalupe Park and the Texas Tech campus lost almost all of their trees. Damage totaled $250 million, ($1,411,900,000 in 2008 dollars), making it the costliest U.S. tornado until it was surpassed by the Omaha Tornado of 1975

The storm's final death toll was 26; victims ranged in age from 9 months to 88 years of age. Many of the victims were found in their homes, where they had been killed by flying debris or structural collapse. One boy lost his life when he was sucked out of the car he was riding in, and an entire family of five died when their house was lifted from its foundation, hurled over 200 yards, and slammed into a field. Another five hundred people were injured.
