EF1 tornado, Salem to (Fnb)Brener Fld Fall, Nebraska, May 18, 2026

From Salem to (Fnb)Brener Fld Fall, this EF1 tornado ran 3.1 miles across Richardson County on May 18, 2026, touching down at 4:55 PM CDT and reaching 200 yards wide. It killed nobody.

Preliminary. This is NWS OAX's damage survey, filed in the Damage Assessment Toolkit as 8 SW Salem. The rating, the path and the casualties are the survey's and can change while it is revised. The Storm Prediction Center compiles the official record of 2026 from these surveys and publishes it in the spring of 2027; this page moves to that tornado's permanent address when it does.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mphthis tornado

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the survey found

At approximately 4:55 PM, a tornado developed near the Nebraska/Kansas border just west of 639 Boulevard, damaging some trees. It continued northeast, crossing 639 Boulevard and producing significant damage to the roof of a large metal outbuilding. The tornado then crossed US Highway 75 just northwest of the intersection with 641 Avenue, causing further tree damage and impacting a second metal outbuilding in the area. Additional tree damage occurred near Rock Creek and 642 Avenue, where the tornado came to an end.

Written by NWS OAX in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

The damage survey

44 damage points were recorded along this path by NWS OAX and NWS TOP, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 107 mph.

  • Barn in poor condition collapsed
  • Old barn lost 30-40% of roof and wall
  • Large trunk snapped lower bound but still around 90 so low end EF1
  • Small barn completely destroyed debris carried about 1/4 mile ENE

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

On the afternoon of May 18, severe thunderstorms produced tornadoes, damaging winds gusts, hail and flash flooding across southeast Nebraska. a strong shortwave trough ejected eastward across the region, providing robust forcing for large-scale ascent. Despite lingering morning cloud cover, very steep mid-level lapse rates combined with the daytime heating of a moist low-level airmass to generate strong instability south of an advancing cold front. Mesoanalysis revealed strong theta-e advection extending from central Kansas through southeast Nebraska and southwest Iowa, highlighting the rapid return of a highly volatile environment. Thunderstorms initially initiated on the warm side of the boundary over northwest Kansas before additional development began over far southeast Nebraska by 2:00 PM CST. This convection initially exhibited discrete supercell characteristics before eventually transitioning into a broader multicell cluster. Additional cells developed north of the cold front across eastern Nebraska, bringing primarily an isolated hail threat. ||The system dropped large hail up to golf ball size (1.75 inches) and generated destructive straight-line winds, including a measured peak gust of 90 mph. The initial supercell storm mode was particularly prolific for tornadogenesis, resulting in 8 tornado across southeast Nebraska. While several of these tornadoes were brief, others caused concentrated damage to trees, farm outbuildings, and irrigation pivots���most notably in Johnson, Nemaha, and Richardson counties. In several instances, these tornadoes were embedded within even broader swaths of intense 80 to 95 mph downburst winds. As the storms transitioned into a messy multicell cluster, torrential downpours also triggered isolated reports of flash flooding.

At approximately 3:46 PM CST, a tornado developed 4 miles east of Bern, KS, and tracked northeast before crossing into Richardson county, Nebraska (see Storm Data for Kansas for more information on the beginning portion of this tornado in Kansas). The tornado continued west of 639 Boulevard, damaging some trees. It continued northeast, crossing 639 Boulevard and producing significant damage to the roof of a large metal outbuilding. The tornado then crossed US Highway 75 just northwest of the intersection with 641 Avenue, causing further tree damage and impacting a second metal outbuilding in the area. Additional tree damage occurred near Rock Creek and 642 Avenue. Maximum estimated wind speeds peaked at 100 mph.

A tornado developed at approximately 4:07 PM CST near the intersection of 646 Avenue and 708 Road, about 1 mile northeast of Salem. Intermittent damage to trees and farm outbuildings was noted between 646 and 647 Avenues. The tornado continued northeast, damaging more trees and breaking power poles along 650 Avenue. Additional damage to trees and farm outbuildings was noted near the intersection of 651 Avenue and 710 Road. The tornado then crossed US Highway 73 and lifted the roof off another farm outbuilding east of 652 Avenue before dissipating shortly thereafter. Maximum wind speeds were estimated at 107 mph.

.DISCUSSION...
Issued at 1155 PM CDT Sun May 17 2026

Today and Tonight...

We had a deceivingly cool, cloudy start to the day.  Temperatures
this morning started off in the 50s at 9 AM, and dipped into the
upper 40s over northeast Nebraska. Farther south, however, Falls
City had already warmed to 70 degrees, on the warm side of a cold
front draped from Beatrice, to Offutt AFB, towards Shelby, IA.
Spotty showers and a few rumbles of thunder developed behind the
boundary this morning. A strong shortwave trough will continue to
eject eastward this afternoon, bringing forcing for large-scale
ascent. Despite the lingering cloud cover, very steep lapse rates
aloft and daytime heating of a moist low-level airmass will likely
support strong instability south of the cold front. Mesoanalysis
depicting strong thetaE advection from central Kansas through
southeast Nebraska and southwest Iowa depicted the abrupt resurgence
of a volatile airmass. Storms have already begun to fire on the warm
side of the boundary over northwest Kansas, and are expected to
develop over far southeast Nebraska by 2 PM this afternoon. Initial
isolated supercells will have the greatest potential for producing
strong, potentially violent tornadoes, very large hail, and damaging
winds, with the greatest risk in far southeast Nebraska. By 4 or 5
PM, CAMS depict more widespread clusters of storms developing, with
the potential for supercell structures. While not as extreme as the
possible intensity over far southeast Nebraska, these storms,
primarily along and southeast of a line from Lincoln to Omaha will
still be capable of producing large hail, damaging winds, and
perhaps a tornado or two.

In addition to hail, winds, and a chance for tornadoes, heavy rain
will also become an issue overnight. Last night's round of
convection brought around 0.5" to 1" of rain across the forecast
area. The potential for a few training storms with 3"+ per hour
rates on top of the already saturated soils will create the
potential for flash flooding across parts of far southeast Nebraska
and southwest Iowa tonight. Therefore, a Flood Watch remains in
effect until 7 AM Tuesday for southeast Nebraska and parts of
southwest Iowa.

Tuesday and Beyond...

We'll see the cold front clear well to the south and east of our
area by Tuesday, putting a cooler Canadian air mass in place
across the region. Tuesday will start out cloudy once again, but
really clear by the afternoon as high pressure builds over our
area. High temperatures on Tuesday will only reach into the
upper 50s to mid 60s. With clear skies and nearly calm winds,
this lends to potential for frost early Wednesday. Overnight
lows will drop into the mid 30s for northeast Nebraska to low
40s across southeast Nebraska and southwest Iowa. Cooler weather
holds into Wednesday though we do see a reversal to southerly
winds and start to advect moisture back into the region. An
upper-level shortwave could potentially bring a few showers to
the area Wednesday afternoon and evening, but the ensembles
haven't picked up on this latest change in the deterministic
guidance. In any case, this wouldn't be anything impactful.

A better chance for showers and storms moves in Thursday as the
longwave trough that's been nearly stationary over the western
US shifts eastward toward our area. With temperatures still in
the sixties for highs, I wouldn't anticipate much of a severe
weather threat with this system for our area.

Temperatures start to rebound on Friday though as we see
enhanced warm air advection ahead of a deepening surface low
which develops on the lee side of the Rockies over eastern
Colorado and western Nebraska. Depending on the track of this
system, we could potentially see more active weather next
weekend with several chances for storms.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1244 PM CDT Mon May 18 2026

Widespread IFR/MVFR ceilings are observed across terminals this
afternoon. Will see an area of scattered showers and storms
overspread KLNK and KOMA after 21z. Have refined timing a bit with
this issuance, but expect further refinements and adjustments.
Storms that affect terminals will likely become severe with strong
winds, very large hail, and the potential for a tornado. Have added
a transition to -SHRA at KOMA and KLNK after 01/02z. Ceilings will
bounce between MVFR/IFR overnight, before largely becoming MVFR late
in the TAF period. Winds from the north northeast will turn to the
north northwest this evening, with gusts gradually increasing to 25
to 30 kts, persisting for the rest of the TAF cycle.

This Hazardous Weather Outlook is for southwest Iowa, west central
Iowa, east central Nebraska, northeast Nebraska and southeast
Nebraska.

.DAY ONE...This afternoon and tonight.

Additional strong to severe storms are forecast this afternoon, with
an increased threat for large hail (2-4+ inches) and strong
tornadoes. Additional chances for heavy rainfall on top of what has
already fallen since Friday night will result in a potential for
flash flooding, particularly for portions of southeastern Nebraska.
Chances to see severe storm activity is maximized over southeast
Nebraska.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.

The probability for widespread hazardous weather is low.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will likely be needed this afternoon and evening.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.
