A fresh round of severe weather is expected to spread across parts of the Midwest and Ohio Valley this week, with damaging winds, large hail, isolated tornadoes and flash flooding all possible before the pattern briefly settles down and another storm threat begins taking shape toward the weekend.
Meteorologist Max Schuster, host of the Max Velocity – Severe Weather Center YouTube channel, said the country is entering an active summer weather pattern that will also include dangerous heat across the southern Plains, cooler air farther north and continued monitoring of the Atlantic for possible tropical development later this month.
The most immediate concern is Tuesday, when Schuster said a strengthening low-pressure system and growing warm sector could create a more organized severe-weather episode from Nebraska and Iowa south toward Missouri and Kansas.
Tuesday Could Bring Powerful Supercells
Schuster said Tuesday has a better chance of producing significant severe weather as low pressure moves east from the Rockies and a pocket of warm, unstable air expands across the central Plains.
The Storm Prediction Center outlook shown in his forecast placed Omaha, Des Moines and Kansas City within a slight risk, while areas farther east toward Milwaukee and Springfield, Illinois, were under a marginal threat.
Schuster said damaging winds appear to be the main hazard and warned that gusts approaching 80 mph could be possible in some of the stronger storms.
Large hail will also be possible.
He said the setup could eventually justify an upgrade to an enhanced risk if confidence continues increasing, particularly if storms remain discrete long enough to develop into powerful supercells before eventually merging into a larger line.
The tornado threat, while more uncertain, will be concentrated around places such as Omaha, Lincoln, St. Joseph, Kansas City and Manhattan, Kansas.
Schuster said that corridor could expand depending on how conditions develop during the day.
That uncertainty is important because the forecast will depend heavily on how quickly the atmosphere recovers and how much instability is available by late afternoon. Severe-weather setups often change sharply when earlier storms leave behind clouds or cooler air, so the exact position of the strongest storms may remain fluid until much closer to development.
Storms Could Explode During The Evening
Schuster expects thunderstorms to already be present in parts of the region during the early and middle afternoon, although the initial activity may produce mostly isolated wind damage.
The more concerning period could arrive around 6 to 7 p.m., when his forecast model showed storms rapidly developing across a broad part of the central Plains.
He said that will be the main window to watch for very large hail, damaging winds and a couple of tornadoes.
Farther north, including near Minneapolis and portions of southern Minnesota, storms may favor hail more than tornadoes, although Schuster said a low-end tornado threat cannot completely be ruled out.
After sunset, the storms are expected to become more linear as they move toward Kansas City and Columbia, Missouri.
That transition could increase the threat from widespread straight-line winds even as the tornado risk begins to decrease.
Schuster also warned that storms may repeatedly move across some of the same areas overnight, creating a flash-flood threat around Topeka, Kansas City and nearby communities.
Several Inches Of Rain Could Fall In Spots
Flooding is another major concern across Iowa, Nebraska and surrounding parts of the Midwest.
Schuster highlighted Des Moines, Davenport, Quincy, Omaha and nearby areas as locations where flooded roads could become more common Tuesday afternoon and evening.
Exact rainfall totals remain difficult to pin down because they depend on where thunderstorms repeatedly develop, but blended forecast guidance showed roughly one to two inches around parts of Iowa.
Schuster said isolated locations could receive much more.
“I think we’ll at least have a few spots near four to five inches of rain,” he said.
That amount falling over a relatively short period could overwhelm drainage systems and make some roads dangerous or impossible to cross.
The combination of wind, hail and flooding makes this setup more complicated than a simple line of thunderstorms. Even communities that avoid the most intense wind could still end up dealing with heavy rainfall after dark.
Ohio Valley Becomes The Focus Wednesday
The severe-weather threat is expected to shift eastward Wednesday as the main storm system reaches the Ohio Valley.
Schuster said thunderstorms may develop from the Great Lakes toward western Pennsylvania, with Detroit, Fort Wayne, Cleveland and areas toward Scranton among the locations that should remain alert.
The main window for severe weather should fall between roughly 3 and 8 p.m.
Damaging winds and isolated hail will again be the primary threats.
A brief tornado will also be possible, with Schuster identifying areas south of Lake Erie, particularly around Akron and Cleveland, as one region where the environment could support some rotation.
He described the tornado risk as low, but not zero.
Storms should weaken during the overnight hours as they continue east.
Another round of more typical mid-August thunderstorms may also form back across Nebraska and Kansas Wednesday, producing hail, gusty winds and frequent lightning.
The repeated nature of these storms is what makes the broader pattern worth watching. No single day necessarily has to become historic for several consecutive rounds of wind, hail and heavy rain to create significant problems.
Severe Weather May Ease Before Returning
By Thursday and Friday, Schuster expects the main organized severe-weather threat to become much less impressive.
The system responsible for the early-week storms should weaken as it moves east, leaving more scattered thunderstorms instead of a concentrated outbreak.
However, the quieter period may not last very long.
Schuster said another area of low pressure could move near the Great Lakes by the weekend and into early next week, potentially triggering another round of severe weather.
Details remain limited at this range, but he said the pattern favors repeated opportunities for storms rather than a prolonged period of calm.
That fits his broader description of an “active summer pattern,” with disturbances repeatedly moving through the northern half of the country while intense heat remains established farther south.
Southern Plains Heat Could Become Brutal
While the Midwest deals with storms, Texas, Oklahoma, Arkansas and nearby parts of the southern Plains will be dealing with dangerous heat.
Schuster said temperatures will remain extremely high through much of the next seven days, particularly around Dallas and surrounding portions of Texas.
The heat should temporarily shift and contract somewhat Wednesday and Thursday as the cold front connected to the severe-weather system pushes farther south.
By the weekend, however, the heat dome is expected to build back.
Schuster said Dallas could approach 110 degrees around Saturday.
Kansas and southwestern Missouri will also experience a surge of heat before the front arrives, including around Springfield.
The Midwest and Great Lakes will see a much different pattern behind the storm system.
Schuster said cooler Canadian air could bring surprisingly comfortable temperatures for August, with overnight lows dropping into the 40s and 50s in parts of the region by the weekend.
Northern Wisconsin could even fall toward 42 or 43 degrees.
That contrast, extreme heat to the south and almost early-fall temperatures farther north, shows just how sharp the air-mass differences will be across the country this week.
Atlantic Tropics Remain Quiet For Now
Schuster also continues to watch the Atlantic Basin, although he said tropical development remains limited for the moment because of strong wind shear and dry air.
He expects another one or two tropical waves could move across the Atlantic before the end of August, potentially creating some chance for development later in the month.
For now, he considers the odds of a system directly affecting the United States to be low.
Still, he cautioned that Gulf and Atlantic waters remain very warm.
If a tropical storm or hurricane ever finds a favorable pocket with less shear and moisture available, Schuster said intensification could happen quickly because the ocean has stored so much heat.
That threat remains more of a longer-range concern than an immediate one.
The more pressing story this week is the procession of severe storms moving from the Plains into the Ohio Valley, followed by another possible disturbance near the Great Lakes toward the weekend.
Schuster’s forecast suggests a week where weather conditions could shift quickly from one hazard to another: supercells and damaging winds in the central Plains, flooding beneath slow-moving storms, severe weather spreading east Wednesday and dangerous heat rebuilding across Texas.
For people in the path of those storms, the main message is straightforward: this is not shaping up to be a one-day event, and several parts of the country may need to remain weather-aware through multiple rounds before the pattern finally begins to relax.
