Here were our updates from throughout the day Monday:
(9:00 p.m. ET) Where Is The Biggest Threat Overnight?
Tonight, a corridor stretching from western and central Oklahoma to central and eastern Kansas faces the most imminent threat. This swath encompasses metropolitan areas like Oklahoma City and Wichita. Strong to intense tornadoes with a rating of EF3 or greater are a real possibility, and this danger could persist into the early hours of Tuesday. As the night progresses, severe thunderstorms are expected to advance eastward into the Missouri Valley, amplifying the risk in that path. Residents of these areas should take immediate precautions and stay vigilant.
(8:40 p.m. ET) Tornado Threat Expands
The National Weather Service has issued a tornado watch for parts of Iowa, Nebraska and South Dakota overnight, until 3:00 a.m. local time. Officials warn the most likely threats could be damaging wind gusts and the potential for scattered spin-up tornadoes.
(8:15 p.m. ET) Confirmed Tornado In Oklahoma
A tornado has been confirmed just southeast of Okeene, Oklahoma, moving east at about 35 mph. Social media photos show part of the tornado hidden by a large wall of rain.
Forecasters say the tornado risk will increase soon in central Oklahoma and southern Kansas as a strong wind jet moves over the area.
(7:35 p.m. ET) Storms On The Move
At least five powerful supercell thunderstorms originating in northern Oklahoma are currently advancing eastward, entering into an environment more conducive to tornadic activity. With this movement across the Plains, there is a higher likelihood we will start to see more strong tornadoes form.
While the majority of severe weather is following the anticipated northeast trajectory, new storm cells are also emerging in western Oklahoma, adding to the need for continued monitoring and precautionary measures.
(6:50 p.m. ET) Stay Alert
In an early-evening message to followers on X, The National Weather Service office in Norman, Oklahoma, posted a reminder that the worst may be yet to come.
Despite a slow start to today’s outbreak, it’s important to note that the potential for dangerous tornadoes will only increase as the night progresses, especially after dark.
(6:00 p.m. ET) Tornado Spotted In Tennessee
Video posted to social media purports to show a tornado on the ground in Smithville, Tennessee. Radar has also confirmed the presence of a funnel.
The National Weather Service warned of impending damage to mobile homes, roofs, windows and vehicles. Tree damage was also likely. A tornado warning remains in place in the area.
(5:45 p.m. ET) Tornado Risk Increases After Dark
Today's severe weather threat is expected to persist into the late evening and overnight, possibly lasting until around 4 a.m. in some areas. That means it’s likely some pretty serious storms could roll through the southern and central Plains after people have gone to sleep.
This is especially scary because tornadoes at night are proven to be a lot deadlier than those during the day. Research shows that while nighttime tornadoes make up only about a quarter of all tornadoes, they cause nearly 40% of tornado-related deaths.
Why is that? Well, when it’s dark, many people don’t see a tornado coming until it’s too late. There also tend to be fewer storm spotters out watching the weather and warning nearby communities. Plus, at night people are usually asleep and might not realize the danger until it's right on top of them.
Go to bed prepared with this list of tips for staying safe amid nighttime severe weather.
(5:05 p.m. ET) May Has A Reputation
May tornado outbreaks, particularly in the Plains, have been historically devastating and deadly. May is the peak month for tornado activity in the U.S., characterized by warm air, jet-stream disturbances, and abundant moisture. Notably, the Plains region, often referred to as "tornado alley," experiences the highest risk during this time.
Over the past 50 years, several memorable May outbreaks have occurred, including the 2011 Joplin tornado, the record 1999 Oklahoma outbreak, and a series of tornadoes in 1973 that included a track stretching the entire width of Alabama. Each of those outbreaks is infamous for significant casualties, injuries, and billions of dollars in damage.

(4:35 p.m. ET) Storms Begin To Ramp Up
This is how it starts. Thunderstorms have begun to develop across Kansas, Oklahoma, Nebraska and Texas. Some of these same storms have the potential to unleash destructive, long-track tornadoes as the day goes on. But first, the area could see large hail and strong, gusty winds.
A landspout tornado was reportedly spotted near central Nebraska, becoming the first official tornado report of this event.
At least one other short-lived tornado has been identified, though far from any populated areas and with no damage reported.
(4:00 p.m. ET) What Is The Dryline?
If you’re keeping a close eye on updates from The National Weather Service today (and you should be), you may have noticed them mention storms developing along the “dryline” in Oklahoma. Let’s explain:
Advertisem*nt
The dryline is an imaginary line through the Great Plains where two very different kinds of air meet up: wet air that comes from the Gulf of Mexico, and dry air that comes from the desert.
When there's a strong storm, this line can move farther east, sometimes reaching all the way to the Mississippi Valley. When this happens, things change pretty quickly. The humidity drops, wind shifts direction and temperatures start going up. These changes can trigger severe thunderstorms, and even tornadoes. So, this dryline is likely to see a lot of action today.
(3:20 p.m. ET) A Particularly Dangerous Situation
A rare Particularly Dangerous Situation Tornado Watch has been issued across parts of Kansas, Oklahoma and Texas.
This means officials have high confidence there could be strong (EF-3) to violent (EF-5) tornadoes in these areas.
Take a close look at the threat info listed in this National Weather Service update, which includes an expectation of hail the size of softballs. The NWS doesn’t use this wording lightly. A ‘particularly dangerous situation’ alert is only used in unique situations when long-lived, powerful tornadoes are in the picture.
(3:00 p.m. ET) Keep Calm and Watch Weather Alerts
Forecasts like this can seem really daunting - especially when such a wide area is at risk. It can be hard to know what to expect or where to begin when making a plan. This helpful infographic from the National Weather Service office in Norman, Oklahoma answers a lot of those questions:
The big takeaway: Stay calm and stay up to date. You can get the latest alerts and information about the incoming storms on The Weather Channel App.
(2:30 p.m. ET) What Makes Today’s Forecast So Concerning?
From weather.com Digital Meteorologist Madeline Scheinost:
“The environment we are seeing is ripe for supercell development. There is a lot of moisture in the area, creating an unstable atmosphere. There is also wind shear, which will help support supercell development. These supercells are expected to produce very large hail and possibly strong tornadoes.”

If that didn’t convince you, weather.com Senior Meteorologist Dina Knightly offers some extra advice: “This is a serious situation and everyone needs to have a plan on where they want to go if a tornado warning is issued. Do not delay. Charge your phones and make a plan now.”
(2:00 p.m. ET) Back In The Bullseye
Almost the entire state of Oklahoma is under some sort of severe risk category, which includes several areas still reeling from last week’s deadly tornado outbreak. Towns like Sulphur, Holdenville and Marietta, Oklahoma that were hit hard just a few days ago are mid-cleanup efforts as they brace for yet another round of extremely dangerous weather.
The same can be said for cities like Westmoreland, Kansas, where one person died and nearly two dozen homes were destroyed by a tornado on Tuesday. The people of Westmoreland find themselves back in the predicted severe area today.
For others, this potential outbreak is seemingly a long time coming. This is the first time all of Oklahoma has been under an NWS “high risk” for severe weather in five years. The last time Kansas received a “high risk” severe designation was May of 2017.
(1:30 p.m. ET) University of Oklahoma Postpones Final Exams
Today is the first day of standard finals week for many University of Oklahoma students. The university announced that any exams after 3:30 p.m. would need to be rescheduled in light of the severe weather forecast. The campus in Norman will close at that time.
School officials issued a press release saying, “Students with final exams scheduled to take place after 3:30 p.m. will be contacted by their instructor to reschedule. OU Online students will continue their regularly scheduled instruction…..We will continue to monitor the weather and OU Emergency RAVE Alerts will be sent as appropriate.”
(1:00 p.m. ET) First Tornado Watch Issued
NOAA's Storm Prediction Center has issued a tornado watch from central Nebraska into north-central Kansas until 7 p.m. CDT. Additional watches will likely be issued through this afternoon and evening.
(12:15 p.m. ET) School Districts Cancel After-School Events, Meetings
After-school and evening events for both Oklahoma City Public Schools and Wichita, Kansas, Public Schools have been canceled. In Oklahoma City, a planned board meeting was also canceled but in Wichita the Board of Education meeting will continue as scheduled.
(12:00 p.m. ET) Will Evening Commuters Be Safe?
From weather.com senior meteorologist Jonathan Erdman: We could see severe thunderstorms kick off as soon as early afternoon in parts of central Nebraska and western Kansas.
However, the peak time of concern for severe thunderstorms and tornadoes in Oklahoma and from central into eastern Kansas will be from late afternoon through late tonight.
That could be as soon as the PM rush in cities such as Lincoln, Nebraska; Wichita, Kansas; and the Oklahoma City metro areas. However, the highest chance of severe weather in those locations appears to be this evening.
Before you start your drive home today, check for any active severe weather warnings in your area. If there are severe thunderstorms in your area, you may want to consider staying put if you have considerable shelter available at work.
(11:00 a.m. ET) Air Force Relocating Planes Due To Severe Weather Risk
Officials from McConnell Air Force Base near Wichita, Kansas, announced they are relocating any planes that aren’t undergoing maintenance due to the threat of severe weather facing the region. Planes were moved just three weeks earlier for the same reason.
(10:30 a.m. ET) NWS Official Shares ‘Key Messages’ About Oklahoma Storm Warnings
A meteorologist with the National Weather Service in Norman, Oklahoma, shared some key messages about today’s storm threat.
Rick Smith warned that "most people will not see a storm, but if you do, it will probably be very bad."
The tornado potential will increase after dark and Smith warned drivers not to get in their vehicles this afternoon without checking the weather first.
