Four-Day Stretch of Severe Storms Targets Central U.S., With Friday Tornado Threat Highest

Powerful spring storms are poised to rumble across the nation’s midsection for several days, with forecasters warning that large hail, damaging winds and tornadoes will threaten millions of people from Texas and Oklahoma to the Missouri and Ohio valleys through at least Friday.

The National Weather Service’s Storm Prediction Center in Norman, Oklahoma, has outlined a multi-day severe weather episode beginning Wednesday, March 4, and continuing into Saturday, March 7. The threat shifts and expands each day, but Friday stands out: Forecasters have issued an “enhanced” risk of severe weather — Level 3 on a five-tier scale — from parts of Texas and Oklahoma north into Kansas and Missouri and east toward the Mississippi Valley.

“Severe storms with large hail, severe wind gusts and tornadoes are expected on Friday and Friday night,” the center wrote in its Day 3 convective outlook issued Wednesday morning.

The unfolding pattern marks one of the first broad severe-weather threats of 2026 as meteorological spring begins. It will test storm-prone communities across the Plains and Midwest and a newly updated federal system for communicating severe weather risk, which is designed to better highlight days when fewer storms may still be particularly intense.

Day-by-day threat

Wednesday: hail and damaging winds, isolated tornado possible

On Wednesday, the Storm Prediction Center placed a “slight risk” of severe storms — Level 2 of 5 — from north-central Texas and eastern Oklahoma northeastward into southern Missouri, Illinois and the lower Ohio Valley.

The center said “isolated to scattered severe thunderstorms” are expected this afternoon and evening, with the main hazards being large hail and localized damaging winds. “A tornado or two will be possible,” particularly near a stalled front where storms can tap into warm, humid air at the surface, the outlook said.

That includes areas near Dallas-Fort Worth and into eastern Oklahoma and western Arkansas, as well as communities along the Ohio River. Local forecasters in Evansville, Indiana, for example, warned residents to prepare for storms capable of damaging winds, hail and heavy rainfall through Thursday, with totals of 1 to 2 inches of rain possible.

Thursday: dryline storms in the Plains

On Thursday, the focus shifts west. A developing low-pressure system over the High Plains is expected to drag a dryline — a sharp boundary between moist and very dry air — through the Texas Panhandle and West Texas into western Oklahoma and south-central Kansas.

The Storm Prediction Center again has a slight risk posted, saying “scattered severe thunderstorms” are expected Thursday afternoon and night. Supercell thunderstorms that form along the dryline could produce large hail, severe wind gusts and “a couple of tornadoes,” forecasters said.

Forecasters with The Washington Post’s Capital Weather Gang noted that some of Thursday’s storms in the Texas Panhandle and western Oklahoma could generate hail at least the size of hen eggs if they remain discrete and powerful before merging into clusters later in the evening.

Friday: highest risk day, potential tornadic supercells

Friday appears to be the peak of the episode.

The enhanced risk zone stretches from roughly northern Texas and central Oklahoma into eastern Kansas and western and central Missouri, including cities such as Oklahoma City, Tulsa and the Kansas City metro area. A broader surrounding slight risk extends from near Chicago and La Crosse, Wisconsin, south through Springfield, Missouri, to Dallas, Waco and Abilene, Texas.

In its outlook, the Storm Prediction Center pointed to a “well-defined 65–85 knot midlevel jet” — a strong band of winds several miles above the ground — sweeping across the southern and central Plains on Friday. Combined with a surge of warm, moist air from the Gulf of Mexico, that jet will create an environment with both significant instability and wind shear, ingredients that favor rotating supercells capable of producing very large hail and tornadoes.

Weather.com characterized Friday as a possible “severe weather outbreak” day, warning of the potential for strong, longer-lived tornadoes from Texas to Missouri if storms develop as projected.

“Confidence is increasing in the potential for some tornadic supercells,” The Washington Post’s weather team wrote in a Tuesday update, adding that storms could persist into “the first half of the overnight” hours.

Saturday: threat likely continues, details uncertain

By Saturday, a cold front is expected to sweep east and south across the southern Plains, Ozarks, mid-Mississippi Valley and Ohio Valley. The Storm Prediction Center has not yet drawn a formal severe-risk contour for that day but said in its extended outlook that “isolated severe threat is likely in some areas,” with the most probable zones stretching from south-central Texas into northern Louisiana and across parts of the Ohio Valley.

Forecasters stressed that confidence in Saturday’s exact threat area and intensity remains low and that later updates could refine the risk.

Classic spring setup

The multi-day threat is being driven by a familiar early-spring pattern.

A dip in the jet stream over the western United States is allowing colder air aloft and a series of upper-level disturbances to roll out over the Plains and Midwest. At the same time, persistent southerly winds are drawing warm, moisture-rich air northward from the Gulf of Mexico, lifting surface dew points into the 60s across much of the southern and central Plains and lower Mississippi Valley.

That combination of moisture, instability and strong winds changing speed and direction with height — known as wind shear — is what supports severe thunderstorms.

On Friday, in particular, the overlap is pronounced: computer models show moderate to strong instability and deep-layer shear across the enhanced risk area, alongside a strengthening low-level jet after sunset. That raises the concern that storms could not only produce tornadoes in the late afternoon and evening but also survive into the night, when many people are asleep and less likely to receive warnings.

New outlook system meets an early test

This week’s event comes on the heels of changes to how the Storm Prediction Center draws its convective outlooks, which are used by meteorologists, emergency managers and the public to gauge upcoming severe weather threats.

In a recent public discussion, the center said it is placing greater emphasis on the expected “strength/intensity/size” of hazards, not just how many storms are likely to occur. Under the new approach, a day with a smaller number of storms but a higher chance of strong tornadoes or very large hail could receive a higher risk category than before.

The center is also adding new hatching and shading options to its maps to better highlight areas where more intense tornadoes, wind or hail are possible.

Friday’s Day 3 enhanced risk is an example of that more forward-leaning posture. Although a more rare “moderate” or “high” risk has not been issued, the elevated designation three days in advance signals that, if storms form as expected, some could be both numerous and intense.

Millions in the path

The evolving severe threat spans a swath of the country that includes major metropolitan areas and vulnerable rural communities.

Dallas-Fort Worth, Oklahoma City, Tulsa, Wichita, Kansas City, Springfield, St. Louis’ outer suburbs, Little Rock, Shreveport, Omaha and cities in the lower Ohio Valley all fall within at least a slight-risk area on one or more days between Wednesday and Friday.

Highways including Interstates 35, 40, 44, 30 and 70 cross the risk zones, as do major freight rail lines and regional airports. Strong winds, large hail and isolated tornadoes could damage power lines and substations, triggering outages that affect communications, medical equipment and businesses. Repeated rounds of storms also raise the threat of localized flash flooding, especially where heavy rain on Wednesday and Friday overlaps.

The corridor from Texas through Oklahoma, Arkansas, Kansas and Missouri also contains large numbers of manufactured and mobile homes, which are particularly vulnerable to tornadoes and severe wind. Many rural and lower-income communities in those states have limited access to basements or purpose-built storm shelters and may rely heavily on outdoor sirens or mobile phones for warnings.

Forecasters urged residents across the risk areas, especially in Friday’s enhanced corridor, to review their severe weather plans now, identify a safe place in a sturdy building, and ensure they have multiple reliable ways to receive warnings — including smartphone alerts, local broadcasters and NOAA Weather Radio — in case storms arrive after dark.

Severe weather in March is not unusual. Tornado activity typically accelerates this month, particularly in the South and lower Mississippi Valley, before shifting north and west into the Plains through late spring. Weather records show that more than 1,700 tornadoes have been documented nationwide in March since 2010.

The Storm Prediction Center’s extended outlook already hints at additional severe weather potential into next week over parts of the southern and central Plains and the Ozarks. For many communities from Texas to the Midwest, this week’s storms may mark not just a single bout of rough weather, but the opening chapter of a long and active severe-weather season.
