TL;DR

A widespread severe weather outbreak struck 30 states on July 4, 2026, generating 862 wind damage reports, 70 hail reports, and 3 tornadoes. The highest concentration of damage occurred across the Midwest and Mid-Atlantic, with Iowa reporting two tornadoes and Colorado confirming a landspout.

What happened on July 4

The Fourth of July brought an unusually active severe weather day across the eastern two-thirds of the United States, with damaging winds dominating the threat profile. According to the NOAA Storm Prediction Center (SPC), 862 wind reports were logged in a 24-hour period ending the morning of July 5—the highest single-day wind report total of the summer so far.

The severe weather was driven by multiple features: a slow-moving cold front draped from Iowa through Pennsylvania and New Jersey, an outflow boundary across Texas, and diurnal heating that destabilized a hot, humid airmass across much of the East and South.

Thirty states reported at least one severe weather event. The affected region stretched from Texas and Louisiana north through the Plains and Great Lakes, and east into the Mid-Atlantic and Northeast.

Wind damage across the Midwest and Mid-Atlantic

The overwhelming majority of severe reports were wind-related. Kansas, Iowa, Minnesota, and the Mid-Atlantic bore the brunt of the damaging gusts.

In Kansas, the Hutchinson Airport measured a 74 mph gust at 1324 UTC. A personal weather station near Macksville recorded 68 mph earlier in the morning. Structural damage was reported in Hartford, where the roof was partially removed from City Hall and windows were broken, according to the Lyon County Fire District 5.

Virginia and West Virginia saw dozens of trees and power lines downed. The National Weather Service office in Sterling, Virginia (LWX) noted "dozens of large trees, branches, and wires blew down in and around Mount Solon" around 1337 UTC.

Maryland experienced widespread tree damage near Glen Burnie, where several trees and power lines fell across the area in the morning hours.

Farther west, Iowa and Minnesota reported numerous downed branches and power outages as storms rolled through the Upper Midwest during the afternoon and evening.

Three tornadoes confirmed in Iowa and Colorado

While wind was the dominant hazard, three tornadoes were confirmed across Iowa and Colorado.

Iowa tornadoes

Two tornadoes touched down in northwest Iowa during the afternoon of July 4:

  • 1611 UTC near Everly, Iowa: A tornado was captured on video moving across a pond and coming onshore approximately 2 miles east-southeast of Everly. The tornado's rating is pending a damage survey by the National Weather Service in Sioux Falls (FSD).
  • 1810 UTC near Greenville, Iowa: A brief touchdown was witnessed by a sheriff's deputy about 3 miles southeast of Greenville. No rating has been assigned.

Both tornadoes occurred in Clay County in the northwest corner of the state, an area that had seen thunderstorm development along a diffuse frontal boundary.

Colorado landspout

At 2359 UTC—just before midnight local time—a brief landspout was reported 6 miles north-northeast of Otis in northeastern Colorado. A storm spotter provided photos of the landspout to the National Weather Service in Boulder (BOU). Landspouts are tornadoes that form along boundaries beneath developing thunderstorms, typically weaker and shorter-lived than supercell tornadoes.

Large hail across Nebraska, Kansas, and Texas

Seventy hail reports were logged, with the largest stones falling across Nebraska, Kansas, and Texas.

The most significant hail event occurred near Pringle, South Dakota, where 2.25-inch hail (larger than golf ball size) fell around 1937 UTC. The National Weather Service in Rapid City (UNR) noted that hail lasted 30 minutes, with the ground covered and numerous stones exceeding 2 inches in diameter.

Nearby Custer, South Dakota, received multiple reports of hail up to 2 inches in diameter between 1932 and 1944 UTC.

In the Texas Panhandle, 2.25-inch hail was reported 10 miles north of Dimmitt around 2033 UTC, according to an mPING report received by the National Weather Service in Lubbock (LUB). Ping-pong ball size hail (1.5 inches) was also reported near Hereford.

Kansas saw widespread quarter-size hail, with a golf ball-size (2.25 inches) report near Argonia around 2130 UTC.

Context: A typical summer severe weather pattern

July severe weather outbreaks are less common than their spring counterparts, but the setup on July 4 was textbook for a summertime wind event: a slow-moving front, abundant low-level moisture, strong surface heating, and a deeply mixed boundary layer.

The SPC Day 1 outlook valid for July 5 (issued after the July 4 event) highlights ongoing Slight Risk areas across Texas, the Ohio Valley, and North Dakota, indicating that the pattern remains favorable for scattered severe weather across multiple regions.

What made July 4 unusual was the geographic scope. Thirty states with severe weather reports in a single day is rare outside of spring outbreak scenarios. The combination of multiple weather features—frontal lift in the Midwest and Mid-Atlantic, outflow boundaries in Texas, and diurnal heating across the South—created a widespread severe weather environment.

Tornado activity remains below average for early July

The three tornadoes reported on July 4 continue a pattern of low tornado activity across the United States in early July 2026. Recent VORTEX blog posts show consistent but modest tornado counts: two tornadoes on July 1 in Iowa and two on June 30 in Colorado.

While tornado reports have been steady, no significant tornadoes (rated EF2 or higher) have been confirmed in recent days, and no tornado watches were issued on July 4 despite the widespread severe weather.

Lessons: Wind is the most common severe weather hazard

July 4's outbreak underscores an often-overlooked fact: damaging wind is far more common than tornadoes during severe weather events. With 862 wind reports compared to 3 tornado reports, wind accounted for 99.7% of tornado and wind reports combined.

Straight-line wind gusts from thunderstorms can exceed 70 mph—equivalent to an EF0 or EF1 tornado—and cause significant structural damage, downed trees, and widespread power outages. Unlike tornadoes, which are geographically focused, damaging winds can affect entire metro areas simultaneously.

The National Weather Service issues Severe Thunderstorm Warnings for wind gusts of 58 mph or greater. These warnings are just as urgent as tornado warnings in terms of the need to seek shelter indoors, away from windows.

Looking ahead

The SPC outlook for July 6 includes a Slight Risk across portions of the Midwest and Southeast, with additional Marginal Risk areas from the Mississippi Valley into the Northern Plains. Scattered severe weather remains possible through the weekend as the active pattern continues.

Residents in Slight and Marginal Risk areas should monitor local National Weather Service forecasts and have a way to receive warnings if severe weather develops.

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.
