A prolonged stretch of severe weather is expected to continue across a large part of the central and eastern United States, with repeated rounds of thunderstorms capable of producing damaging winds, large hail, isolated tornadoes and dangerous flash flooding through the middle of the week.
Meteorologist Max Schuster, host of the YouTube channel Max Velocity – Severe Weather Center, said the pattern is unusual for August because several disturbances are expected to ride around a strong area of high pressure in the southern Plains, keeping the Midwest and Ohio Valley unusually active for days at a time.
“Over the next three days, multiple disturbances and strong instability will fuel rounds of severe thunderstorms from the Midwest into the Ohio Valley and Appalachians,” Schuster warned.
Tuesday Brings A Broad Severe Weather Threat
For Tuesday, August 11, Schuster highlighted a large slight risk of severe weather stretching from around Chicago and Peoria through parts of Kentucky and into Virginia.
A broader marginal-risk zone extends from the northern Plains all the way toward Washington, D.C., putting a large number of people under at least some threat of severe storms.
The biggest concern appears to be damaging straight-line winds.
Schuster said some thunderstorms could produce gusts between 80 and 85 mph during the daytime as storms develop from around Chicago eastward toward West Virginia.
Large hail is also possible, particularly farther west across the northern Plains, while tornadoes cannot be ruled out.
“I think this will be more of a straight-line damaging wind threat,” Schuster said, although he added that tornadoes could become embedded within a line of thunderstorms.
That distinction matters because a powerful line can affect a much larger area than an isolated supercell. Even without a tornado, winds approaching 80 mph can bring down trees, damage buildings and knock out power across wide areas.
Storms Could Keep Coming Through Ohio
One of the areas Schuster appeared most concerned about was the Ohio Valley, where repeated rounds of thunderstorms could continue moving through many of the same places.
He said another batch of storms is expected to cross areas around Columbus and Cincinnati during the morning, followed later by additional development farther west.
“Those storms are pretty much going to be non-stop in these areas,” Schuster said.
Later Tuesday morning, a more organized line is expected to develop across Wisconsin and Illinois before becoming more widespread during the afternoon.
Schuster said that system could produce winds from 60 to 85 mph, with the threat expanding east and southeast as the day progresses.
By Tuesday evening and overnight into Wednesday, the line may continue toward Virginia.
The repeated nature of the storms may be just as important as their individual strength. A location that gets hit once by severe wind may recover quickly, but several rounds of heavy rain and thunderstorms can create much more serious problems, particularly if soils become saturated and creeks or drainage systems begin rising.
Flash Flooding Could Become A Major Problem
Schuster said the same overall pattern is also creating a multi-day flash-flood threat.
A stalled frontal boundary and repeated northwest-to-southeast storm tracks may allow thunderstorms to pass over the same areas again and again, a process meteorologists often call “training.”
That setup is particularly concerning across parts of the Midwest and Ohio Valley.
Schuster explained that storms may repeatedly overlap because the atmospheric pattern is steering them along similar paths, meaning rainfall totals could build rapidly even if individual thunderstorms are moving.
The flood threat could remain in place through the middle of the week.
This may be one of the less dramatic hazards compared with tornado footage or extreme wind damage, but repeated flooding can quickly become the more widespread danger. Roads that are passable during one storm may become dangerous after several more rounds, while areas that normally handle heavy rain can eventually run out of capacity.
Wednesday Keeps The Severe Weather Going
The pattern is not expected to break on Wednesday.
Schuster said another large severe-weather risk stretches from Nebraska eastward toward Charlotte, with damaging wind once again expected to be the main hazard.
Large hail and a few tornadoes could also develop.
He described the overall setup as a “ring of fire” pattern, with high pressure parked over the southern Plains while disturbances travel around its northern and eastern edge.
That circulation can create a storm track extending through the Plains, Midwest and Ohio Valley.
“Storms are just going to be slingshotting around this thing,” Schuster said.
The strong high-pressure system is also expected to increase heat across the Great Plains and parts of the Southeast, meaning one section of the country could be dealing with extreme temperatures while another sees repeated severe thunderstorms.
Schuster said the storm train may continue through at least Thursday.
An Unusual August Pattern Could Last Into The Weekend
What makes the setup especially notable, according to Schuster, is how long it may last.
He said the Midwest could remain active through roughly August 20, with repeated severe-weather opportunities continuing well beyond the first few days of the week.
“This is not a weather pattern that we’ve really had much of over the last three or four years,” he said.
Schuster estimated that it may have been four or five years since the region experienced such a persistent stretch of elevated severe-weather risk during August.
Forecast models suggest storm activity could continue across the Midwest, Ohio Valley and central Plains on Thursday and Friday.
Late Friday into Saturday may become especially interesting, with Schuster watching Minnesota, Iowa and Wisconsin for the possibility of a more significant severe-weather day involving damaging winds, hail and tornadoes.
Saturday could then bring another round across the Great Lakes, Ohio Valley and central Plains.
By Sunday and Monday, Schuster said any organized severe-weather threat may become more focused toward the East Coast, although confidence decreases considerably at that range.
The length of this event is what makes it stand out. Many summer severe-weather episodes come and go quickly, but this pattern may repeatedly reload, giving communities little time between rounds.
The Atlantic Is Starting To Wake Up
At the same time, Schuster said tropical activity in the Atlantic Basin is beginning to increase.
Several disturbances are being monitored, including one system in the eastern Atlantic that he said had a 60% chance of development over the following seven days.
Another disturbance east of the Lesser Antilles carried about a 10% chance of formation and could bring heavier rain to the islands around the weekend.
A third area north of Bermuda also had a relatively low chance of development.
Schuster said most of the systems may remain weak, but the disturbance with the higher development probability has a better chance of becoming an organized tropical cyclone around Thursday or Friday.
Even then, strong wind shear could limit rapid strengthening near the Lesser Antilles.
Looking farther ahead, some model guidance brings the system relatively close to Bermuda early next week, while other solutions turn it out to sea.
Schuster said the immediate risk of a major United States impact appeared low, but cautioned that it was still too early to stop watching the system.
“It is hurricane season,” he said.
A Busy Pattern With Several Hazards At Once
Schuster’s forecast paints a complicated picture for the rest of the week.
The Midwest and Ohio Valley face repeated severe thunderstorms, damaging winds and flooding, while the southern Plains remain under strong high pressure and building heat. Meanwhile, the Atlantic is finally showing more signs of tropical development.
For Tuesday and Wednesday in particular, the most widespread concern appears to be damaging wind, with localized tornadoes and hail layered on top of the flood threat.
The repeated storm rounds make this setup more dangerous than a single severe-weather day because communities may deal with several different hazards before the atmosphere finally settles down.
Schuster’s message was that residents across the Midwest and Ohio Valley should expect an unusually active period rather than assume one round of storms will be the end of it.
For mid-August, that is what makes the developing pattern so unusual: the severe-weather season is behaving as though it has plenty of energy left.
