A multi-day severe weather system moving across the central U.S. is placing more than 25 million people at risk of damaging storms, large hail, and flash flooding, with hazards shifting east through the Plains and into parts of the Midwest. Forecasters warn re
The sky over the central United States is already doing what it does in a heightened season: breaking into violent rounds that leave people watching the radar, checking local alerts, and making the same decisions over and over—whether it’s time to head indoors.
This week. forecasters say a widespread severe weather system sweeping across the Plains could put more than 25 million people at risk of damaging storms. large hail. and flash flooding as the threat shifts eastward. It’s not a single storm. but a multi-day pattern expected to persist. with new disturbances moving through and triggering additional rounds of storms each afternoon and evening.
The National Weather Service says the event may bring a mix of hazards, including destructive winds and isolated tornadoes. The repeated nature of the threat matters: storms are expected to redevelop daily across a broad corridor. keeping residents in multiple states on edge long after the first wave moves through.
Forecasters link the setup to a highly active weather pattern driven by a dip in the jet stream. warm temperatures. and moisture streaming north from the Gulf. Those ingredients are combining to produce severe thunderstorms capable of large hail, damaging wind gusts, and isolated tornadoes. At the same time, the odds for flash flooding rise as repeated downpours soak the same areas.
As the system progresses, the highest risk is expected to extend from New Mexico and Texas north through the Dakotas. Storm activity is forecast to expand into states including Nebraska, Kansas, Iowa, Minnesota, and Missouri as the system tracks eastward. By later in the week. storms are expected to bring severe weather risks into additional Midwest areas as the front stalls and interacts with warm. unstable air.
The Storm Prediction Center is highlighting the possibility that storms may become strong to severe, producing large hail and severe wind gusts. The forecast calls for a Slight Risk, level 2 out of 5, of severe thunderstorms across parts of the Northern Plains into the Upper Mississippi Valley.
Flooding concerns are also in the forecast, with training thunderstorms and high rainfall rates potentially leading to localized flooding. The Weather Prediction Center’s excessive rainfall outlook includes a Slight Risk. level 2 out of 4. over west Texas into New Mexico. as well as the eastern Dakotas.
For people trying to plan their week, the timing has been just as hard to shake as the danger. On Monday. severe storms erupted across Colorado. including the Denver metro area. where hail as large as golf balls fell and forced drivers to stop along highways. The following day. Tuesday. severe thunderstorms were reported from the Dakotas through Nebraska and into surrounding states. continuing the multi-day outbreak.
Additional rounds have continued across the central U.S., with storms redeveloping daily and spreading across the Plains.
Officials are urging residents in the threat zone to stay alert because conditions can change quickly. Large hail and damaging winds can develop with little warning, and flash flooding can occur rapidly in areas that see repeated rainfall.
Safety guidance is direct: monitor forecasts and local alerts throughout the day. move indoors to a sturdy building at the first sign of severe weather. and avoid windows during hail or high winds. Residents are also advised not to attempt to drive through flooded roadways and to identify a safe shelter location ahead of potential warnings.
With a multi-day system expected to keep rolling—storm after storm. day after day—the main challenge for communities from the Plains into the Midwest may be the same one emergency managers always face in active outbreaks: not just reacting to the first warning. but staying ready for the next round when it comes in the afternoon and evening.
