Overnight Tornado Activity Across the Southern Plains

Seven tornadoes were reported across Kansas and Oklahoma between late evening April 26 and early morning April 27, 2026, according to local storm reports compiled by the NOAA Storm Prediction Center (SPC). The tornadoes were accompanied by 186 hail reports and 64 wind damage reports spanning eight states from the central Plains into the Mississippi Valley.

All seven tornado reports came from southeastern Kansas and north-central Oklahoma, concentrated in a roughly two-hour window between 2347 UTC April 26 (6:47 pm CDT) and 0205 UTC April 27 (9:05 pm CDT).

The National Weather Service has not yet issued Enhanced Fujita Scale ratings for any of the tornadoes as of this writing. Damage surveys are typically conducted in daylight hours following overnight events.

Where the Tornadoes Touched Down

The first tornado report came from 5 miles northwest of Sycamore, Kansas at 2347 UTC, described as a brief touchdown. A second tornado was confirmed by a storm spotter 3 miles west-southwest of Sycamore roughly 15 minutes later.

In Oklahoma, the NWS office in Tulsa (TSA) documented spotter video of a tornado approximately 2 miles south of Foraker at 0055 UTC. A related report three minutes later noted power lines down south of Foraker, though it is unclear whether this damage was tornado-related or caused by straight-line winds.

Additional Kansas tornadoes were reported:

  • 5 miles east-southeast of Cherryvale at 0055 UTC — "A couple brief rope tornado touchdowns between 7:45pm and 8pm," with location estimated from radar
  • Altamont at 0132 UTC — Tornado reported on the ground
  • 4 miles southwest of Bigheart, Oklahoma at 0205 UTC — Tornado on the ground for approximately 4 minutes, crossing Highway 99 north of U.S. Highway 60, per radar data

None of the local storm reports from the NWS offices in Wichita (ICT) or Tulsa (TSA) included descriptions of significant structural damage, though the Foraker power line report and the Bigheart highway-crossing tornado suggest at least EF0-level intensity.

A Prolific Hail Event

While tornadoes grabbed headlines, hail was the dominant severe weather hazard overnight. The Storm Prediction Center logged 186 hail reports across the central Plains and lower Mississippi Valley, with the largest stones reaching 2.00 inches in diameter near Madison, Kansas at 2008 UTC.

Other notable hail reports included:

  • 1.75 inches near Hillsboro, Kansas at 1755 UTC
  • 1.75 inches near Erie, Kansas at 2017 UTC, described as "just slightly smaller than a golf ball"
  • 1.50 inches in Canton, Kansas at 1806 UTC, with a separate report at 1732 UTC noting hail "piling up"

Kansas bore the brunt of the large hail, with dozens of reports clustered along a corridor from McPherson and Marion counties southeastward through Labette and Montgomery counties. Smaller hail (1.00 to 1.25 inches) was also reported in Illinois, Louisiana, and other states earlier in the day as the broader severe weather system developed.

Wind Damage Across the Region

Sixty-four wind reports were filed across eight states, with the most significant damage occurring in Kansas and Missouri. The NWS office in Wichita estimated 80+ mph winds 5 miles west of Neosho Falls, Kansas at 2103 UTC, accompanied by quarter-size hail.

Other notable wind damage included:

  • Homes damaged and barn destroyed 6 miles south-southwest of Edgerton, Kansas
  • Several downed power poles in Slater, Missouri at 1224 UTC
  • Numerous trees down and structural damage in Renick, Missouri around 1235 UTC
  • Large tree through roof of a house in Lehigh, Kansas at 1757 UTC

Wind gusts of 60-70 mph were measured or estimated at multiple locations in Kansas and Missouri, consistent with the damaging wind threat outlined in SPC convective outlooks issued prior to the event.

The Broader Severe Weather Setup

The overnight tornadoes occurred on the leading edge of a multi-day severe weather outbreak across the central United States. As of the morning of April 27, the Storm Prediction Center had issued a Moderate Risk (Level 4 of 5) for severe thunderstorms across parts of Missouri and Illinois, with the outlook emphasizing "a threat for multiple strong to intense tornadoes (EF-3+), widespread severe/damaging wind gusts, and scattered large to very large hail."

The SPC's 0745 am CDT outlook noted that "a very favorable corridor for intense supercells and strong tornadoes is apparent this afternoon/evening across parts of MO into IL." The agency warned that "multiple strong to intense tornadoes (EF-2/3+) appear likely, especially from parts of MO into IL along/near the effective front."

The overnight Kansas and Oklahoma tornadoes developed ahead of this main threat window, occurring in the warm sector as discrete supercells formed along weak low-level boundaries. The environment featured strong low-level wind shear and moderate instability—classic ingredients for tornadoes, though not at the extreme levels forecast for the following day farther east.

Context: An Active April Pattern

The seven tornadoes reported overnight bring the multi-day total to at least 48 tornadoes across the central United States since April 23, based on recent VORTEX blog coverage. Previous events this week included:

  • April 26: 13 tornadoes across Nebraska, Oklahoma, and Texas
  • April 25: Tornado near Kiowa, Oklahoma amid a giant hail outbreak
  • April 24: 21 tornadoes across Iowa, Kansas, and Oklahoma

This sustained pattern of severe weather is typical for late April in the central Plains and Mississippi Valley, when strong upper-level storm systems interact with warm, moist air surging northward from the Gulf of Mexico. The current system is notable for its longevity and geographic scope, with severe weather reports spanning from the Rockies to the Ohio Valley over a four-day period.

What Happens Next

As of 7:45 am CDT April 27, multiple severe thunderstorm watches remained in effect across Illinois, Missouri, and surrounding states, with expiration times ranging from 10:00 am to 4:00 pm CDT. No tornado watches were active at the time of this writing, though the SPC's Moderate Risk outlook suggests tornado watches are likely to be issued later in the day as the main severe weather threat develops.

Residents across the mid-Mississippi Valley, lower Ohio Valley, and Mid-South should monitor weather conditions closely throughout the day. The SPC has emphasized that the tornado threat may extend into the evening and overnight hours, particularly along and ahead of the cold front as it pushes eastward.

Nighttime tornadoes present unique challenges for public safety. Third-party weather apps are silenced by Do Not Disturb mode on most smartphones, though Wireless Emergency Alerts (WEA) for tornado warnings still break through on most phones by default. For those who want an additional layer of protection, VORTEX Pro places phone calls when tornado warnings are issued—calls bypass Do Not Disturb entirely, ensuring you're alerted even while asleep.

Damage Surveys Pending

The National Weather Service will conduct ground and aerial damage surveys in the coming days to assign official Enhanced Fujita Scale ratings to the seven tornadoes. Survey teams examine damage indicators such as structural damage, tree fall patterns, and vehicle displacement to estimate maximum wind speeds.

EF ratings range from EF0 (65-85 mph winds) to EF5 (over 200 mph winds). The majority of tornadoes in the United States are rated EF0 or EF1, though the current severe weather pattern has elevated potential for stronger tornadoes given the favorable atmospheric conditions.

This post will be updated if significant findings emerge from damage surveys or if casualty information is released by local authorities.

VORTEX is a free web app at vortexintel.app that monitors severe weather nationwide. Pro ($4.99/month) places phone calls to your phone when a tornado or flash flood warning is issued for a location you care about — calls can ring through Do Not Disturb once you enable Emergency Bypass for the number, unlike most third-party app notifications.
