The late-May 1957 tornado outbreak occurred from eastern New Mexico to Oklahoma, western Arkansas, southern Kansas, eastern Colorado, and southeastern Wyoming on May 24–25, 1957. 37 tornadoes touched down over the area, most of which took place across northern and western Texas, in addition to southern Oklahoma. The strongest tornado was rated at F4 status south of Lawton. Unusually, some tornadoes touched down during the early morning hours, whereas most Plains tornadic systems are nocturnal.[2] Four deaths were attributed to the tornadic activity. The tornado outbreak was related to the arrival of a strong shortwave trough.[3]
Meteorological synopsis
An upper-level trough moved over the central United States. Subsequently, a tornado outbreak took place over portions of Kansas, Nebraska, Missouri, and Oklahoma on May 20. Cold upper air temperatures and marginal low level moisture produced severe weather across the southern and central Great Plains. On May 21, this shortwave trough and a deep surface low produced an additional violent (F4)[1] tornado in Minnesota, while tornadoes killed 15 people in Missouri. On May 22, another area of low pressure was centered over southwest Oklahoma in attendance with a front, which extended from central New Mexico to Missouri. A weakening Pacific cold front dissipated near Del Rio. In Texas, low-level moisture, originating from the Gulf of Mexico, remained abundant during the four days that preceded the May 24 outbreak.[2] Eventually, lifted index values increased to -10, which correlated with surface-based CAPE values near 3,500 j/kg.[3] On May 23, dewpoints rose across western Texas, and temperatures reached 77°F in the warm sector. On May 24, high moisture levels surged into southeastern New Mexico on both sides of a warm front. A new surface low pressure area also developed over New Mexico.[1][2] Later, fog developed northward to Amarillo, in tandem with exceptionally high dew points. The tornadoes that occurred formed along and just north of the warm front.[2]

| List of confirmed tornadoes | ||||||
|---|---|---|---|---|---|---|
| New Mexico | ||||||
| F2 | E of Melrose to SE of Bellview | Curry | 1100 | 36.5 miles (58.7 km) | This tornado may have developed between 3:30–4:30 a.m. (MST),[2] though it was first noted at 5:00 a.m. MST. It may have formed in Roosevelt County. Some barns were destroyed. This event may have consisted of a sequential series of tornadoes; therefore, it may have constituted a tornado family. At least six funnels may have been involved.[4] | |
| Texas | ||||||
| F2 | S of Bovina to Bushland area | Parmer, Delta, Randall, Potter | 1630[4] | 70.1 miles (112.8 km) | Buildings were destroyed on the grounds of eight farms near Friona, and homes near Black were also damaged. Funnel clouds instigated traffic accidents in Hereford, injuring three people. Several funnels were reported from Clovis, New Mexico, to the Amarillo area.[4] | |
| F0 | N of Enochs | Bailey | 1719 | 0.5 miles (0.80 km) | Rural power poles and electrical wires sustained damage.[5] | |
| F0 | Hereford area | Deaf Smith | 1730 | 1 mile (1.6 km) | The tornado was originally observed near Hereford, where it produced no damage.[5] A separate funnel cloud was observed northwest of Wildorado around 11:17 a.m. (1717 UTC). The funnel may have also developed in Death Smith County. The sighting occurred in rural areas.[2] | |
| F3 | Olton area | Lamb | 1838 | 1.9 miles (3.1 km) | 77 homes were destroyed in Olton. The southern section of the town received the most severe damage. Rural farm buildings, located southwest and northeast of Olton, were also destroyed. Three injuries were attributed to the tornado; however, residents were informed by advance warnings.[4] | |
| F3 | Tahoka area to NE of Ralls | Lynn, Lubbock, Crosby | 1900 | 37.3 miles (60.0 km) | Roof damage affected 100 buildings in Tahoka. In Wilson four homes received damage. Buildings also incurred roof damage in the Robertson area. In Savage, twelve homes were destroyed or unroofed. Two homes and two barns were destroyed west and north of Ralls. The damage patterns suggest that the event was a tornado family. One source cites a path length of 50 miles (80 km), which differs from official records.[4] | |
| F0 | NW of Halfway[5] | Hale | 1900[5] | 0.5 miles (0.80 km) | Houses, barns, and trailers were destroyed. The tornado also caused livestock deaths. The tornado formed from the same storm that produced the Olton tornado.[4][5] | |
| F? | Cotton Center area to SW of Plainview[2] | Hale | 1930 | 10.5 miles (16.9 km) | One home, located north of Cotton Center, was shifted 100 feet (30 m) off its foundation. Three homes were unroofed or destroyed near the termination of the path. Nine homes also received minor damage. Four funnel clouds were reported nearby.[4][2] | |
| F0 | W of Cliffside | Potter | 1950 | 0.3 miles (0.48 km) | Brief touchdown. Continuation of the Bushland tornado family.[5] | |
| F3 | WNW of Midland to Lenorah area[4] | Midland, Martin[4] | 2030[4] | 30 miles (48 km)[4] | About 50 power poles were downed near State Highway 158. The funnel stalled for 20 minutes prior to the resumption of northeast movement. Farm houses were reportedly destroyed northwest of Stanton. In Lenorah, five homes were impacted, but only one home was destroyed. Two or three tornadoes may have been present in this tornado family.[4] | |
| F2 | NNW of Midland | Martin | 0028 | 2 miles (3.2 km) | Another tornado touched down and remained over sparsely populated areas.[2] One source disputes the F2 rating.[4] | |

The swath of F4 damage occurred south of Lawton. About 12 homes were destroyed, and 70 cattle were killed. One car was transported for 100 yards (0.05 miles).

The funnel may have remained aloft until it encountered Wanette and destroyed frame buildings.[4][6] The final report of damage was a destroyed barn northwest of Macomb. Official records list a maximum intensity at F2 status, while another source claims that the tornado attained F3 intensity.[4] | |

Notable tornadoes
After a six-hour gap, two tornadoes developed near Bovina and Enochs. The former tornado moved northeast across Parmer County and traveled nearly 40 miles to a point west of Amarillo. It destroyed eight farms near Friona, while storm-associated funnel clouds caused injuries near Hereford. The second tornado moved east-northeast and lifted over northern Hale County. It dismantled 77 homes near Olton and caused $650,000 (1957 USD) in damages.[2] Subsequently, four tornadoes developed over the next three hours. One tornado, sighted around 11:17 a.m. (CDT), occurred 20 miles northwest of Wildorado. It remained over rural areas and inflicted no damage.[2] Officially, this tornado was not recorded in the National Weather Service database.[1] Another tornado, touching down around 1:00 p.m. (CDT), affected Lynn County. It formed near Tahoka, where roof damage occurred. The funnel skipped north-northeast. In Wilson, four homes incurred damage. Homes were demolished in Slayton, and twelve homes were destroyed in Savage. The event, comprising a tornado family, dissipated east of Cone.[2] Officially, the event is recorded as a single tornado. The strong tornado attained F3 intensity on the Fujita scale. Eventually, tornadoes affected seven states and caused four fatalities. Additionally, at least one undocumented tornado was reported southeast and east of Midland around 6:30–7:15 p.m. (0030–0115 UTC).[2] A brief tornado also may have touched down near Moore in the Oklahoma City metropolitan area, breaking tree branches and windows.[5]
