A new storm system is expected to keep the United States in an unusually active late-August weather pattern, with severe thunderstorms shifting into the Northeast on Thursday before another, potentially stronger system develops across the Northern Plains and Midwest over the weekend.
Meteorologist Max Schuster, host of the Max Velocity – Severe Weather Center YouTube channel, said the changing pattern will also bring a sharp temperature contrast, with another push of cool Canadian air settling into parts of the Great Lakes, Ohio Valley and Northeast before intense heat surges north through the Plains.
Schuster said that combination of storms, heat and repeated cold fronts could keep severe weather going into the first week of September, extending what he described as the most active August for severe weather that he has covered nationally.
Northeast Faces Severe Storms Thursday
The immediate severe-weather threat shifts into the Mid-Atlantic and Northeast on Thursday, where Schuster highlighted a slight risk covering portions of New York and Pennsylvania along with parts of New Jersey and Maryland.
A broader marginal risk surrounds that area.
Damaging wind gusts are expected to be the main concern, although Schuster said some storms could also produce small hail and perhaps a couple of tornadoes across parts of Vermont, New York, Massachusetts, Connecticut, Pennsylvania and New Jersey.
Storms should begin developing during the afternoon and organize into clusters stretching from the Washington, D.C., region north toward Burlington, Vermont.
If individual supercells can form before the storms become more clustered, Schuster said an isolated tornado threat could develop, although he continued to emphasize wind damage as the primary hazard.
The storms are expected to continue into the middle and late evening before weakening as daytime heating fades, with most activity likely becoming non-severe after roughly 10 p.m. Eastern time.
That setup does not appear to be a major tornado outbreak, but the broad area involved means a large population could still deal with damaging thunderstorms during the afternoon and evening commute.
Friday Brings Storms To The Southeast
The severe threat should ease somewhat on Friday, although Schuster said the weather will remain unsettled across the Southeast and along the Carolina coastline.
Widespread thunderstorms are possible from around New Orleans northeast toward Virginia Beach, with damaging wind gusts again the main concern.
He did not expect much of a tornado threat with that activity, describing it more as a typical late-August round of strong to severe thunderstorms.
At the same time, another noticeable cooldown will spread into areas farther north.
Schuster said low temperatures Friday morning could fall into the 40s, 50s and 60s across parts of the Midwest, Ohio Valley and Northeast as another push of Canadian air moves south.
That cool air will not last long.
By the weekend, strong southerly flow is expected to pull much hotter air back north, setting up a dramatic temperature swing across the central United States.
Weekend Storm Could Increase Severe Threat
Schuster said the more significant part of the forecast may begin Saturday as a new low-pressure system develops across the Northern Plains.
There is still considerable uncertainty over the exact strength and track of the system, but he is watching the Dakotas and northwestern Minnesota for an elevated severe-weather threat.
Strong southwesterly flow could create a more organized environment for storms, and Schuster said there may be some tornado potential depending on how the surface low develops.
Sunday could bring another round of severe weather farther east and south, including parts of the Great Lakes and Central Plains.
By then, Schuster expects winds aloft to become more westerly, which may favor a greater straight-line wind threat compared with the potentially more tornado-friendly environment Saturday.
The details remain uncertain enough that the exact areas and hazards could shift, but the broader signal is clear: another organized storm system is expected to cross a region that has already seen repeated rounds of severe weather this month.
That persistence is notable because late August is often a transitional period, yet the central and northern United States continue to behave more like a spring severe-weather corridor.
Heat Surges North Behind The Cooldown
While cooler air settles temporarily into the Great Lakes and Northeast, Schuster said a major heat surge will build across the Central and Southern Plains.
Texas and Oklahoma are already dealing with intense heat, and the hotter air is expected to expand north through the weekend.
By Saturday, Schuster said 100-degree temperatures could return to parts of Iowa and Nebraska, where that kind of heat has been absent for some time.
Strong southerly flow from the Gulf will help transport the heat northward at the same time the Northern Plains storm system begins organizing.
By Sunday, the hot air should push farther into the Midwest and Central Plains.
That interaction between strong heat to the south and a developing low-pressure system to the north is one of the reasons Schuster is watching the weekend for a more organized severe-weather setup.
A cold front should then sweep through parts of the Midwest Monday and Tuesday, bringing another cooldown to areas around Chicago, Wisconsin and Minnesota.
Farther south, however, Kansas City and St. Louis may remain hot even into the opening days of September.
Schuster described the overall setup as a weather “roller coaster,” with repeated switches between Canadian air and late-summer heat.
Severe Weather Could Continue Into September
The active pattern does not appear likely to end with the weekend system.
Schuster said the middle of next week and the first week of September could bring several additional rounds of isolated to scattered severe thunderstorms.
Cities and regions he highlighted included Minneapolis, Chicago, Columbus and Cincinnati.
He said it has been surprisingly difficult to find a meaningful break in the severe-weather pattern and described August 2026 as the most active severe-weather August he has covered during roughly four and a half years of national forecasting.
Schuster connected some of that activity to the developing El Niño pattern, noting that while the Atlantic has been relatively quiet for tropical systems, severe thunderstorms across the continental United States have remained unusually frequent.
If the current signals hold, the first days of September may continue that pattern rather than delivering an immediate seasonal slowdown.
Atlantic Tropical Activity May Finally Increase
Schuster is also watching a disturbance in the Atlantic that he said has a high chance of becoming the next named tropical storm.
If it develops, the system would be called Tropical Storm Dolly.
He put the formation probability at roughly 70% over both the next two days and the next seven days, with the disturbance moving west through the main development region.
At this stage, Schuster said there is too much uncertainty to know whether it will even reach the Lesser Antilles or survive into the central Atlantic.
Wind shear farther west could interfere with development, so he cautioned against making assumptions about the eventual track or strength.
The broader Atlantic basin remains unusually quiet for late August, while the Pacific has been considerably more active, with multiple areas of tropical development south and east of Hawaii.
Schuster said warm Pacific waters associated with El Niño should support continued tropical activity there during the coming weeks.
For the continental United States, though, the more immediate concern remains the repeated sequence of severe storms, rapidly changing temperatures and expanding heat.
Thursday begins with the Northeast under the gun for damaging thunderstorms, but the larger story will unfold through the weekend as another storm organizes over the Northern Plains and pulls both severe weather and intense heat into a new phase.
