What you need to know

Four tornadoes touched down across Iowa, Kansas, and Kentucky on August 19, 2026, capping a widespread severe weather day that generated 136 wind reports and 25 hail reports across 18 states. The most significant event occurred overnight in Lowes, Kentucky, where a tornado damaged multiple homes and downed trees across a three-mile stretch.

Where the tornadoes touched down

The National Weather Service received four tornado reports spanning the central Plains and the Ohio Valley:

  • 2 E Marsh, Iowa — Two landspout tornadoes were reported near Marsh in east-central Iowa around 1952 and 1957 UTC (2:52 PM and 2:57 PM CDT). Multiple spotters observed the brief touchdowns, which dissipated quickly. The NWS office in Davenport issued a correction clarifying that both reports represented separate, short-lived landspouts.
  • 4 S Oakley, Kansas — Emergency management relayed a report of a possible landspout tornado south of Oakley in western Kansas at 2210 UTC (5:10 PM CDT). The tornado occurred in open country with no damage reports.
  • Lowes, Kentucky — The most significant tornado of the day struck Lowes in Graves County, Kentucky, at 0450 UTC (11:50 PM CDT on August 19). The NWS office in Paducah reported that multiple homes were damaged and numerous trees were downed along a three-mile stretch of Highway 131 near the three-mile marker. Spotters observed a tornadic debris signature (TDS) on radar, strongly indicating tornado damage. No EF rating has been issued yet, but damage surveys are expected in the coming days.

All four tornadoes remain unrated as of this writing. The Iowa and Kansas events were classified as landspouts, a type of weak tornado that forms along a boundary without a mesocyclone.

The Lowes, Kentucky tornado: what we know

The overnight tornado in Lowes represents the most impactful event of the day. According to the NWS office in Paducah, the tornado caused damage to multiple homes and downed "lots of trees" over a three-mile section of Highway 131 in Graves County.

The report noted a tornadic debris signature visible on radar, a feature that indicates lofted debris and confirms tornado damage. TDS is often associated with stronger tornadoes, though the extent of structural damage will determine the final EF rating.

No injuries or fatalities have been reported. Damage surveys by NWS Paducah are expected to confirm the tornado's path length, width, and intensity rating in the next 24 to 48 hours.

Graves County lies in western Kentucky, a region that has seen significant tornado activity in recent years, including the catastrophic December 2021 outbreak. Lowes is a small community roughly 20 miles west of Mayfield.

Widespread wind and hail reports

Beyond the tornadoes, severe thunderstorms produced widespread wind damage and large hail across the central United States.

Wind damage was most concentrated in Nebraska, where 136 total wind reports were logged nationwide. The NWS office in Grand Island documented numerous reports of downed trees, snapped power poles, and structural damage across central Nebraska. Notable reports included:

  • 6 NNW Greeley, Nebraska — 82 mph wind gust, the strongest measured gust of the day.
  • Greeley, Nebraska — Tree damage throughout town, with winds estimated in excess of 60 mph.
  • 5 WNW Giltner, Nebraska — At least three power poles snapped.
  • Ericson, Nebraska — Trees and power lines down in and south of town.

Wind damage extended into Iowa, Kansas, Mississippi, Florida, and other states as storms tracked eastward through the afternoon and evening.

Hail reports totaled 25, with the largest hailstone measuring 3 inches in diameter. That report came from 8 SSW Thurman, Colorado, at 0126 UTC, where a trained spotter documented mostly 1-inch hail but noted a few 3-inch stones on their property. Other notable hail reports included:

  • Mora, New Mexico — 1.75-inch (golf ball) hail, confirmed via social media photo.
  • 11 NNE The Monument Rocks, Kansas — 1.50-inch (ping pong ball) hail, documented in a Facebook photo.
  • 1 NNW Seibert, Colorado — 1.75-inch hail.

Hail was most common across the central Plains and the Southwest, where monsoon moisture supported scattered severe thunderstorms.

The broader severe weather pattern

The severe weather on August 19 unfolded under a broad upper-level trough over the central United States. According to the Storm Prediction Center's Day 1 Convective Outlook, a shortwave trough embedded in northwesterly flow provided lift for scattered thunderstorms from the central Plains into the Mid-Atlantic.

In the central Plains, a cold front moving southward from the western Great Lakes into Nebraska and Kansas served as a focus for supercell development. Forecast soundings showed elongated hodographs aloft and moderate instability, supporting isolated to widely scattered storms capable of large hail, damaging winds, and a few tornadoes.

Farther east, a warm front lifting northward across the Mid-Atlantic supported a risk for damaging wind gusts, while a surface trough in the lee of the Appalachians focused convection across the Southeast.

The SPC did not specify the risk category that was in force at the time of the tornado reports, but the outlook narrative emphasized scattered severe storms with a mix of hazards.

Nighttime tornadoes and warning challenges

The Lowes, Kentucky tornado struck at 11:50 PM local time, underscoring the heightened danger of nocturnal tornadoes. Nighttime tornadoes pose a particular challenge because people are asleep and less likely to receive warnings in time to take shelter.

Wireless Emergency Alerts (WEA) for tornado warnings bypass Do Not Disturb mode on most smartphones by default, ensuring that even sleeping residents receive a loud alert. However, third-party weather apps are silenced by Do Not Disturb unless users manually configure notification settings.

VORTEX Pro addresses this gap by placing phone calls when a tornado warning is issued for a saved location. Once you enable Emergency Bypass for the VORTEX number, calls ring through Do Not Disturb at full volume — a critical feature for overnight tornado threats.

What's next

As of early August 20, no tornado or severe thunderstorm watches are active. The SPC Day 1 outlook valid through 12Z August 21 highlights a Slight Risk for scattered severe storms across portions of the Mid-Atlantic, the Midwest, and the central Plains, with damaging winds, large hail, and isolated tornadoes possible.

Damage surveys in Lowes, Kentucky, are expected to provide an EF rating and additional details on the tornado's path in the coming days. VORTEX will update this post if significant new information becomes available.

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.
