Meteorologist Max Schuster is warning that a powerful storm system could produce several days of severe weather across a wide part of the country, beginning with a major threat in the Midwest on Monday before shifting into the Ohio Valley, Northeast, Mid-Atlantic, and parts of the East Coast later in the week.
In a forecast published on his channel Max Velocity – Severe Weather Center, Schuster said a strong upper-level trough diving into the Midwest and Great Lakes would create an environment favorable for supercells, widespread damaging winds, large hail, and at least a few tornadoes. At the same time, forecasters are also watching a developing tropical disturbance in the Gulf of Mexico that could bring heavy rain and strong winds to parts of the Gulf Coast.
The combination makes this an unusually busy stretch of summer weather, with different regions facing separate hazards over several consecutive days. Although the exact severity will depend on how storms develop each morning, Schuster said Monday and Tuesday appear to carry the greatest widespread risk.
Monday’s Storm Threat Centers On Wisconsin
The most immediate concern is a level three out of five enhanced risk of severe weather covering much of Wisconsin, including Milwaukee, Madison, Janesville, and Green Bay, while a slight risk extends into areas including Chicago, Des Moines, and Minneapolis.
Schuster said numerous severe storms are likely to develop during the afternoon and evening, with damaging winds expected to be the main danger. One or more clusters of thunderstorms could organize and move across Wisconsin, Iowa, Minnesota, and Illinois, producing wind gusts that may reach 60 to 85 mph or possibly higher in isolated locations.
Those wind speeds are strong enough to knock down trees, damage roofs, cut power, and turn unsecured outdoor objects into dangerous debris. Schuster advised residents to secure trampolines, patio furniture, and other loose items before the storms arrive.
Large hail is another serious concern, especially during the first storms that develop before they merge into larger clusters. Minneapolis, Rochester, Green Bay, and surrounding areas could see hail approaching baseball size if stronger supercells form.
A few tornadoes are also possible, with the highest risk expected across central and southern Wisconsin, northern Iowa, and areas near Rochester. Schuster identified Cedar Rapids and Wausau as locations that should remain especially alert, while Minneapolis, Chicago, and parts of western Michigan face a lower but still present tornado threat.
The complicated part of Monday’s forecast is that morning storms may influence what happens later. More morning thunderstorm activity could stabilize the atmosphere and reduce the tornado threat, but it may also encourage a larger and more widespread damaging wind event.
If the morning is quieter, however, the atmosphere could recover more quickly, allowing isolated supercells to form before storms combine into lines. That scenario would create a greater risk of tornadoes during the early and middle afternoon.
Multiple Rounds Could Strike The Same Communities
Storms are expected to begin developing between roughly 1 p.m. and 3 p.m. south and east of Minneapolis and across central and southern Wisconsin. The early storms could produce damaging winds and tornadoes before becoming more widespread later in the afternoon.
By around 4 p.m., Schuster expects storms to increase near Madison and north of Milwaukee, with more clusters developing near La Crosse, Rochester, and other parts of Wisconsin and Minnesota. By early evening, storms could be moving toward Chicago and southwestern Michigan.
One of the more concerning details is that some communities may be struck more than once. Schuster said places such as Madison and Janesville could experience two or even three separate rounds of thunderstorms as multiple clusters pass through during the afternoon and evening.
That possibility matters because repeated storms can compound the damage. Trees weakened by the first round may fall during the next, while power crews and emergency responders may have little time to assess conditions before another line arrives.
Schuster stressed that the strongest overall signal is still for destructive winds rather than a major tornado outbreak. He said several tornadoes are possible, but the atmosphere would need to come together almost perfectly for Monday to become a particularly significant tornado day.
Even without a large tornado event, an organized wind threat covering several states could still cause widespread disruption. Straight-line winds approaching hurricane strength can damage large areas at once, especially when storms develop into fast-moving lines.
Thunderstorms are expected to continue into northern Illinois, northern Indiana, and nearby areas late Monday night. Another round may also form in Iowa before moving east, adding to the possibility of repeated wind damage.
Ohio Valley Faces Another Enhanced Risk Tuesday
The severe weather threat will continue Tuesday across a much more heavily populated corridor, with an enhanced risk covering Cincinnati, Columbus, and Pittsburgh.
A slight risk stretches through Cleveland, Buffalo, Philadelphia, Washington, D.C., and Richmond, while a lower threat reaches Nashville, Charlotte, and parts of western New England. Schuster said damaging winds, large hail, and tornadoes will all be possible.
The leftover storms from Monday night will play an important role in determining how Tuesday develops. If they leave behind stable air or widespread clouds, the threat could be reduced in some places, but if the atmosphere recovers quickly, several new clusters may form during the afternoon.
Schuster expects storms to begin developing around early afternoon in several separate areas, including central Pennsylvania, near Syracuse, between Pittsburgh and Columbus, and farther west across Indiana and Illinois.
Any isolated storm that forms early could produce a tornado, especially if it remains separate from other storms. However, Schuster believes the storms will probably merge rather quickly, making damaging winds the dominant hazard once again.
The strongest localized tornado environment may develop near Cincinnati, Louisville, and Columbus. Schuster said this area could have somewhat better conditions for rotating storms during the early and middle afternoon, although the overall tornado risk still appears lower than the damaging wind risk.
A strong tornado cannot be completely ruled out, particularly near Louisville or Cincinnati, but Schuster cautioned that the available forecast values generally point toward a low-end tornado environment. In most locations, any tornadoes that form would be more likely to remain on the weaker side.
By late afternoon and evening, storms could become widespread across Kentucky, Ohio, Pennsylvania, New York, and surrounding areas. Two large lines of thunderstorms may eventually develop, potentially bringing widespread wind damage toward Allentown, New York City, and Albany.
Schuster also raised the possibility of a derecho if the system continues to strengthen. That outcome remains uncertain, but the mention reflects how organized and extensive the wind threat could become if storms merge into a long-lived complex.
Severe Storms Shift Toward The Carolinas
By Wednesday, the main severe weather threat should move closer to the East Coast, especially across the Carolinas and far eastern Virginia.
Schuster said scattered severe storms may develop from around Washington, D.C., southward toward Columbia, South Carolina, although the strongest concentration may remain closer to Raleigh, Charlotte, Virginia Beach, and coastal areas.
The threat is expected to be more isolated than on Monday or Tuesday, but damaging wind gusts and a couple of tornadoes will still be possible. Forecast confidence is lower because detailed high-resolution model data was not yet available for Wednesday.
This gradual eastward progression is typical of a large summer storm system, but the duration is notable. Instead of one isolated day of severe weather, the same broad system could create dangerous conditions in different regions over three straight days.
That kind of setup can also make public attention harder to maintain. People who miss the first round of warnings may assume the threat is over, even though the danger is simply shifting into another state or region.
Tropical Development Adds A Second Concern
While the severe weather system moves across the northern and eastern United States, Schuster is also monitoring an area of low pressure spinning in the Gulf of Mexico, west of Tampa.
He said the disturbance had a 50% chance of becoming a tropical cyclone over the following several days, with development depending heavily on how far west it travels. A track farther south and west would give the system more time over warm Gulf waters and improve its chances of strengthening.
The most likely outcome, according to Schuster, is a tropical depression or weak tropical storm bringing heavy rain to part of the central or eastern Gulf Coast. If it becomes a named tropical storm, it would receive the name Bertha.
Some forecast models showed the system gradually strengthening south of Pensacola before moving toward Alabama, Mississippi, Louisiana, or the Florida Panhandle by Wednesday. A smaller number of model runs carried the system farther west toward Texas, which would give it more opportunity to strengthen into a strong tropical storm or hurricane.
Schuster described three broad possibilities. A quicker move into the Florida Panhandle would probably limit development, while a track toward Pensacola or New Orleans would offer a better chance of a low-end tropical storm.
The least likely scenario would take the system much farther west toward Houston. Schuster estimated that possibility at around 10%, but said a western track could allow considerably more strengthening.
Regardless of whether the system earns a name, flash flooding is expected to be the primary concern. Several inches of rain could fall near Tallahassee, Pensacola, New Orleans, or other coastal communities, while wind gusts near landfall could reach around 50 to 60 mph.
This is an important distinction because tropical systems do not need to become hurricanes to create dangerous conditions. Slow-moving weak storms can still produce major flooding, especially along coastal roads, low-lying neighborhoods, and areas with poor drainage.
Schuster urged Gulf Coast residents to remain aware without panicking, noting that the forecast remains uncertain and could change as the disturbance moves across the Gulf.
An Active Week Requires Close Attention
The forecast points to a difficult opening to the week, beginning with a potentially destructive wind event across the Upper Midwest, followed by another round of severe weather across the Ohio Valley and Northeast.
Monday’s storms may bring repeated rounds of damaging winds, very large hail, and a few tornadoes across Wisconsin and nearby states. Tuesday then carries a similar threat across a larger population center stretching from Kentucky and Ohio into Pennsylvania, New York, and the Mid-Atlantic.
By Wednesday, severe weather should become more scattered along the East Coast, but the developing Gulf system may be approaching land at roughly the same time.
The most important message in Schuster’s forecast is that the exact details will continue to change, especially as morning storms influence each afternoon’s setup. Residents across the affected regions should have several ways to receive warnings, know where they will shelter, and avoid waiting until storms are already visible before taking action.
With severe storms moving through several regions and a tropical disturbance developing at the same time, this week’s weather may demand more attention than a typical midsummer pattern.
