Live updates: Dangerous storms to lash Illinois, Ohio, Indiana with huge hail, tornado threat
Follow live updates as dangerous severe storms capable of producing tornadoes, huge hail, and 70 mph winds target nearly 50 million people across the Midwest and Ohio Valley. Track the latest radar, timing, and local reports for Detroit, Indianapolis, and Chicago as this powerful system moves through ahead of a dramatic flashback freeze tonight.
While March is making a quiet exit for some, the FOX Forecast Center is already looking ahead to a volatile start to April.
The historic heat dome that has dominated the country is finally expected to break down this Sunday and shift eastward.
This shift is a game-changer; it opens the door for powerful Pacific storms to move inland and strengthen.
The FOX Forecast Center says severe storm chances will increase during the opening days of April.
As we head into April 1–2, a significant zone stretching from the Plains to the Mississippi Valley will be in the crosshairs for a new round of severe weather.
This transition is a classic spring setup. Cooler air surging out of the West is slated to collide with warm, moisture-rich air sitting over the central U.S., creating the perfect ingredients for severe thunderstorms.
While it is too early for specific storm outlooks, the signals are clear: an active and potentially dangerous pattern is returning.
This aligns with historical trends, as April is the second-most active month for tornadoes in the U.S., averaging 197 nationwide. Texas typically leads the charge with an average of 25 tornadoes in April, followed closely by Mississippi and Alabama, which each average 16.
While the focus today is on the severe storm threat, the grand finale of this weather system is a dramatic and punishing temperature drop that the FOX Forecast Center is calling a "flashback freeze."
As the powerful cold front slices through the Midwest and Ohio Valley this evening, it will replace record-breaking afternoon warmth with a surge of Arctic air. In cities like Chicago, Indianapolis, and Detroit, temperatures that peaked in the 70s and 80s this afternoon will crater behind the storm line.
Temperatures are forecast to dip below freezing on Friday morning after a cold front sweeps through the Midwest.
This isn't a gradual cool-down; we are tracking a rapid plunge where values could drop 20 to 30 degrees in as little as one hour immediately following the rain.
By Friday morning, the spring-like air will be a distant memory as lows bottom out in the 20s and 30s across the Great Lakes and Mid-Mississippi Valley.
This represents a total 24-hour temperature swing of nearly 50 degrees for some communities. The transition will be so sharp that any lingering moisture behind the front could briefly turn into a few flurries or light snow showers before the air dries out.
If you’ve already started your spring planting or moved sensitive pots outdoors, you need to take action now to protect them. You’ll go from running the AC during the storms this afternoon to cranking up the furnace by the time you wake up tomorrow.
The FOX Forecast Center is tracking a significant threat for huge hail—stones exceeding 2 inches in diameter—across central Illinois, Indiana, and northern Ohio this afternoon.
These storms are being fueled by intense daytime heating that will eventually erode the atmospheric cap, allowing air to surge upward at explosive speeds into a high-energy environment.
With strong wind flow reaching 60 mph or more in the upper atmosphere, these storms are likely to form as organized supercells.
These rotating updrafts act like a powerful vacuum, suspending moisture in the freezing layers of the storm long enough for massive layers of ice to build up, potentially producing hailstones the size of eggs or tennis balls that can easily shatter windshields and damage property.
Severe thunderstorms could produce huge hail across Illinois, Indiana, and Ohio through the evening hours.
The window for this huge hail threat is expected to be highest during the initial storm development between 2:00 p.m. and 6:00 p.m. local time, specifically targeting a corridor from Springfield, Illinois, through Indianapolis, and over to Cleveland.
While these individual supercells will eventually congeal into a solid line—shifting the primary threat from hail to damaging straight-line winds—the early-evening period remains the most volatile for significant ice.
If you have a vehicle or outdoor equipment in these areas, now is the time to secure them under a sturdy roof before the atmosphere pops and these high-impact storms begin their trek across the Ohio Valley.
For communities in Kankakee County, Illinois, and across the state line into Northwest Indiana, today’s severe weather threat isn’t just a forecast—it’s a haunting reminder of the destruction that struck just over two weeks ago.

On March 10, a powerful EF-3 tornado packing 160 mph winds tore a 35-mile path through the region, leveling homes in Aroma Park, destroying businesses, and tragically claiming lives as it tracked into Lake Village, Indiana.
As families continue to clear debris and navigate the early stages of insurance claims, the FOX Forecast Center warns that these same vulnerable areas are back in the crosshairs of a Level 3 out of 5 severe risk.
With the atmosphere primed for giant hail and more tornadoes before a dramatic freeze tonight, the psychological toll is high for residents who are once again forced to seek shelter among the ruins of their neighborhoods.
Today’s severe weather threat is a waiting game that centers on a late-afternoon breakout. While a capping inversion is keeping the skies relatively clear for much of the morning and early afternoon, this atmospheric lid is expected to fail between 3:00 p.m. and 5:00 p.m. local time.
As the cold front pushes into the record-warmth and moisture surging up from the Gulf, storms will ignite rapidly from eastern Illinois into Indiana and northern Ohio.
Residents in Chicago, Indianapolis, and Detroit should be prepared for a very sudden transition from sunshine to severe thunderstorms just as the evening commute begins.
Severe storms are expected to develop late this afternoon and into the evening across the Midwest and Ohio Valley.
As we move into the evening and overnight hours, the individual storm cells are forecast to organize into a fast-moving, cohesive line.
By 8:00 p.m. to 10:00 p.m., this line will stretch from roughly Kansas City to Pittsburgh, shifting the primary threat from giant hail to damaging straight-line winds.
These storms won't quit when the sun goes down; they are expected to rumble through the Ohio Valley and into the Mid-Atlantic overnight, finally clearing the coast by Friday morning.
Behind this line, the flashback freeze begins immediately, with temperatures crashing 30 to 50 degrees in just a few hours.
If you’re looking out the window in Chicago or Indianapolis right now, you might see plenty of sunshine and feel unseasonably warm air. It feels like a beautiful spring day, but to a meteorologist, this is the calm before the storm—quite literally.
The atmosphere is currently under what we call a cap, and it’s the only thing keeping severe weather at bay for the moment.
Think of the cap like a lid on a pot of boiling water. Right now, the sun is heating the ground, and warm, moist air from the Gulf of America is surging in at the surface.
This creates a massive amount of energy (or instability), but that energy is trapped. A layer of even warmer air a few thousand feet above our heads is acting as that lid, preventing the air at the surface from rising. As long as that lid stays on, storms cannot form. But the longer the lid stays on, the more pressure builds underneath it.
The breakout: From 0 to 60 in minutes
As we head into the late afternoon, two things will happen to break the cap. First, the afternoon sun will continue to bake the ground, making the surface air so buoyant that it eventually punches through the lid.
Second, a powerful cold front is arriving from the west, acting like a giant wedge that physically forces that warm air upward.
When that cap finally fails, the transition is often explosive. The FOX Forecast Center says it’s like taking the lid off that boiling pot: all that pent-up energy is released at once, and you can see a tiny cloud turn into a 40,000-foot-tall severe thunderstorm in a matter of minutes.
Because the energy has been building all day, the storms that break through will have immediate access to all that fuel. This is why we are concerned about significant hail (larger than 2 inches) and a few tornadoes the moment these storms initiate.
A cold front slamming into warm, humid air will help trigger the development of severe thunderstorms later today.
What this means for you
- Watch the sky: Once the first storms fire—likely after 3:00 or 4:00 p.m.—they will grow rapidly.
- Commuter alert: The timing of the cap break aligns perfectly with the evening rush hour for much of the Ohio Valley.
- Don't be fooled: Just because it’s sunny now doesn't mean the threat has passed. In fact, the more sun we see this afternoon, the more fuel will be available when the storms finally erupt.
Severe weather is expected today across the Midwest and Ohio Valley as a Level 3 out of 5 threat targets nearly 50 million people, including those in Chicago, Indianapolis, and Cleveland.
Severe thunderstorms are expected across the Midwest and Ohio Valley later today.
While an atmospheric "cap" is expected to hold storms at bay through much of the day, intense daytime heating and a surge of moist air from the Gulf will collide with an advancing cold front by late afternoon, triggering explosive thunderstorm development.
These volatile storms will be capable of producing giant hail exceeding 2 inches in diameter, damaging wind gusts over 60 mph, and a few strong tornadoes—particularly along the northern edge of the system—before congealing into a dangerous line that will race toward the Mid-Atlantic overnight.
Following this severe threat, residents should prepare for a dramatic flashback freeze as temperatures are forecast to plummet 30 to 50 degrees by Friday morning, potentially bringing a brief transition to light snow in the storms' wake.
