A pair of large storm systems is expected to drive an unusually active stretch of weather across the United States this week, with repeated severe thunderstorms threatening parts of the Midwest, Ohio Valley and Northeast while a developing tropical disturbance brings a separate flood risk to the Gulf Coast.
Meteorologist Max Schuster, host of the YouTube channel Max Velocity – Severe Weather Center, said damaging winds, large hail and isolated tornadoes could remain possible through the end of the work week as one major system spins across Canada and repeatedly sends storm energy into the northern and eastern United States.
At the same time, Invest 97L in the northern Gulf is expected to organize as it approaches the Texas and Louisiana coast, potentially becoming a weak tropical storm before moving inland.
“This is going to be a very active week of weather,” Schuster said.
Severe Weather Builds Across Several Regions
The broad pattern begins with a large heat dome remaining firmly established across the southern Plains and Southeast, while a major dip in the jet stream develops farther west and a large storm moves through Canada.
For Texas and Oklahoma, Schuster said the persistent heat is unlikely to disappear anytime soon.
“It has been brutally hot for weeks now and it is going absolutely nowhere,” he said.
Farther north, however, the Canadian system is expected to help produce several separate rounds of severe thunderstorms from the northern Plains into the Midwest, Great Lakes and Northeast.
For Tuesday, Schuster is watching two main areas: the Northeast and parts of the central and northern Plains.
Around New York City, thunderstorms are expected to develop during the afternoon, with damaging winds, large hail and perhaps a couple of tornadoes possible.
Schuster said one model showed a particularly favorable corridor for tornado development around Allentown, Philadelphia, Toms River and Atlantic City between roughly 5 and 6 p.m., although that outcome depends on the position of a boundary and whether individual storms remain discrete rather than quickly merging together.
If that setup fails to materialize, damaging straight-line winds would still remain the primary concern.
A second area of storms may form farther west across South Dakota, where a few supercells could produce damaging winds and isolated hail. Schuster expects the tornado threat there to remain lower.
Wednesday Could Bring The Greatest Severe Threat
Schuster said Wednesday currently looks like the most concerning day of the week.
As the larger storm system continues moving through Canada, thunderstorms should spread across the Great Lakes and Northeast, with several clusters potentially developing from around Albany westward toward Cleveland.
Damaging winds, large hail and tornadoes would all be possible.
“I do foresee Wednesday being the best shot of all hazards of severe weather,” Schuster said.
He also pointed to elevated significant tornado parameter values, which suggest the atmosphere may become supportive of rotating thunderstorms in at least some areas.
Storms are expected to become most active from about 2 p.m. through 9 p.m., with the threat potentially reaching the Washington, D.C., region during the evening.
That makes Wednesday particularly important because the expected risk covers heavily populated parts of the Northeast and Mid-Atlantic. Even a relatively small number of severe storms can become a major problem when they move through densely populated corridors during the afternoon and evening.
Thursday Brings Another Round
The severe-weather threat may not end after Wednesday.
Schuster said Thursday could look like a “rinse and repeat” setup, although the main area may shift somewhat farther south.
Central and southern Pennsylvania, New Jersey, Delaware and Maryland could see another round of damaging winds, hail and isolated tornadoes.
Minnesota may also see a few supercells Thursday, although Schuster expects that threat to remain much more isolated.
By Friday and Saturday, additional thunderstorms could develop again across portions of the Midwest, creating another smaller severe-weather risk.
The repeated nature of these rounds is what makes the pattern stand out. Rather than one single outbreak moving through and ending, the atmosphere may remain favorable for several different storm episodes over multiple days.
Gulf Disturbance Could Become A Tropical Storm
While severe weather develops farther north, Schuster is also watching Invest 97L in the northern Gulf of Mexico.
He said the disturbance south of New Orleans has a much better chance of developing than most Atlantic systems seen so far this season and could become Tropical Storm Edward before reaching the Texas coast.
The system is expected to move generally toward Houston and Beaumont, with the main concern being heavy rainfall rather than strong winds.
Schuster believes it will probably remain a low-end tropical system and could make landfall around southeastern Texas on Tuesday.
If it remains just offshore long enough to organize, localized rainfall totals of roughly three to six inches could develop near the coast.
Areas around Beaumont, Winnie and Galveston may therefore face some localized flooding, while storm surge could reach around two feet in isolated locations.
Schuster also mentioned the possibility of gusty winds, but he does not expect this system to become particularly powerful.
The interesting part is simply that the Atlantic has been so quiet this year. Even a weak named storm would represent one of the more notable bursts of tropical activity the basin has managed to produce.
Another Atlantic System Bears Watching
A second disturbed area remains near the Greater Antilles and Caribbean.
Schuster said this system consists largely of disorganized thunderstorms and may move toward Florida during the next couple of days.
He believes the odds of meaningful development remain low.
Despite some social-media speculation that the disturbance could eventually become a hurricane in the Gulf, Schuster said he considers that outcome highly unlikely.
“I think it’s very unlikely this does become anything more than just a big blob of rain heading towards Florida,” he said.
The main limiting factor remains wind shear.
Schuster said the Atlantic and Gulf are still being strongly influenced by El Niño, which has produced unusually hostile upper-level winds for tropical development.
For the first 25 days of August, he said wind shear across the Atlantic basin reached the highest levels measured in roughly 50 years.
That helps explain why so many tropical disturbances have struggled to organize despite warm water.
California Could See A Rare Tropical Threat
Another potentially unusual development is taking shape in the eastern Pacific.
Schuster said computer models are increasingly suggesting that a hurricane could form there during the coming days before curving north toward California by late in the weekend or early next week.
He does not expect the system to remain a hurricane if it reaches California, but a moderate or stronger tropical storm could still be possible.
That would bring risks of heavy rain, flooding and strong winds from around Los Angeles northward, potentially toward San Francisco depending on the eventual track.
Schuster compared the scenario to Hurricane Hilary from several years ago, noting that tropical systems reaching California are uncommon enough that the possibility deserves attention even while forecasts remain uncertain.
Most models have shifted toward some version of that setup, he said, which makes it more notable than a single outlier projection.
Still, the exact strength and path remain far from settled.
That uncertainty is important because tropical systems interacting with cooler waters and the West Coast terrain can change quickly. At this range, the larger signal matters more than any exact rainfall or wind forecast.
Heat Remains Locked Across The South
Away from the storms, the heat dome across the southern Plains is expected to remain stubborn.
Schuster said strong high pressure may continue dominating Texas, Oklahoma and surrounding areas into the second week of September.
That could limit the amount of cooler air reaching much of the central United States, although the Great Lakes, Midwest and Northeast may still see occasional breaks behind storm systems.
Meanwhile, southwesterly flow along the West Coast should continue supporting showers and thunderstorms across portions of the Rockies.
The result is a highly divided weather map: persistent heat in the South, repeated severe storms farther north and east, tropical moisture threatening the Gulf Coast, and the possibility of an unusual Pacific system approaching California.
Schuster’s forecast does not point to one single nationwide storm, but rather several different systems interacting at once.
That is what makes the week so active.
From severe thunderstorms Tuesday through Thursday to Gulf Coast flooding and the possibility of a rare tropical system reaching California later, much of the country could experience very different forms of hazardous weather within the same seven-day period.
