This article provides an expert, long-range look at a renewed round of severe weather sweeping across a large swath of the United States. After Tuesday’s storms brought tornadoes to southern Wisconsin and damaging winds from Texas to New England, forecasters are tracking a broad risk corridor that could impact more than 130 million people in the coming days.
Overview of the Forecast
Forecasters from the Storm Prediction Center continue to refine risk areas for Wednesday through Thursday. There is significant potential for tornadoes, large hail, and damaging winds.
The weather setup features a persistent front and evolving drylines. Warm, moist air can fuel intense convection from the Southern Plains into the Midwest and Ohio Valley.
Widespread Severe Thunderstorm Threat
The risk is not uniform, but the potential is broad. A broad corridor from North Texas through the Southern Plains, Midwest, and Ohio Valley is placed in a Level 2 out of 5 severe thunderstorm risk.
An accompanying Level 1 risk includes the Dallas metro area and Texas Hill Country, signaling scattered severe storms are possible even where the overall threat is lower.
- Level 2 risk spans a wide swath from North Texas through the Southern Plains, Midwest, and Ohio Valley.
- Level 1 risk covers the Dallas metro and Texas Hill Country, indicating a lower but nonzero chance of severe storms.
- A dryline is forecast to set up across eastern Kansas, Oklahoma, and West Texas, a classic trigger for supercells and squall lines capable of large hail, tornadoes, and damaging winds.
- Heavy rain and the potential for flash flooding accompany these storms, especially where storms train over the same locations.
Tornadoes, Hail, and Damaging Winds: Lessons from Tuesday
Tuesday’s activity produced radar-confirmed tornadoes in Iowa, Illinois, Wisconsin, and Michigan, with notable damage in Waukesha County, Wisconsin. Long-track tornadoes tracked across eastern Iowa, underscoring the potential for tornadic systems to stay organized across multiple states.
Hail reached baseball size in parts of Wisconsin and Indiana, with Madison reporting 3-inch hail. Alongside hail, damaging winds accompanied many reports across the Midwest.
Hydrological Risks: Flooding Threats and Snowmelt
Beyond hail and wind, heavy rainfall coinciding with rapid snowmelt raises flash-flood concerns in the Great Lakes region. Repeated storm training—a sequence of storms moving over the same area—could worsen localized floods even as temperatures rise elsewhere.
- Rapid snowmelt increases soil saturation and runoff potential, amplifying flood risk in vulnerable basins.
- Persistent rain in the Great Lakes region may challenge drainage systems and elevate creeks and small rivers quickly.
Warmth as a Fuel: Ohio Valley and Mid-Atlantic
Record warmth in the Ohio Valley and Mid-Atlantic is primed to contribute to convective development. Scattered thunderstorms could produce hail and damaging gusts as far north as New Jersey and even New York City.
Forecasts emphasize the role of heat and humidity in sustaining instability that can overcome weaker air masses at times. This can create pockets of severe weather that require close monitoring by residents and motorists.
East Coast and Beyond: The Final Stages
As storms move toward the East Coast, forecasters expect activity to weaken. Weaker thunderstorm development may linger into Thursday across the Deep South, Mid-Atlantic, and Northeast.
A few hail-producing storms could still affect New York’s Capital Region, Central New York, and the Finger Lakes region.
Preparedness and Safety Tips for Severe Weather
Given the multi-day window of potential severe weather, individuals should stay informed and ready to respond.
Planning and situational awareness are key to minimizing risk during rapid weather changes.
- Monitor forecasts regularly and heed local warnings from the National Weather Service and emergency management agencies.
- Prepare an emergency kit with essentials, including water, food, a flashlight, batteries, and a battery-powered weather radio.
- Secure outdoor objects that could become projectiles in high winds.
- Review your household tornado plan.
- Avoid flooded roads—even shallow water can conceal hazards; turn around if you encounter water covering roadways.
- Stay indoors during storms and seek shelter in a sturdy interior room away from windows during tornado warnings or confirmed tornadoes.
