Widespread severe weather expected in east-central US today

According to the NOAA’s Storm Prediction Middle, more than 100 million people in east-central and mid-southern U.S. states face a Danger of severe weather today, March 30, 2025. The organization announced yesterday:

A widespread/ substantial severe weather episode is forecast across an area centered on the Ohio/ Mid and Lower Mississippi/ Lower Missouri/ Tennessee River Valleys. Very large hail, damaging winds, and Powerful tornadoes are Predicted.

Cities including Indianapolis, Indiana; St. Louis, Missouri; Nashville, Tennessee and Little Rock, Arkansas face what the Storm Prediction Middle calls an enhanced Danger, the third of five Danger levels. That means widespread or persistent storms are Predicted, along with numerous severe storms, which are those capable of producing inch-sized hail, wind gusts of 58 miles per hour, or tornadoes.

This area also faces the possibility of significant severe weather. This is when a storm is capable of producing hail of at least 2 inches in diameter, wind gusts of 75 miles per hour, or a tornado that produces damage that ranks at least 2 on the Enhanced Fujita scale.

When will the storms impact me?

Storm Schedule will vary depending on where you live. The Primary of two potential waves of thunderstorms is Predicted Prompt Sunday morning for the western side of the at-Danger areas. The line of severe storms could develop as Prompt as Overdue morning or Prompt afternoon, before moving east through the afternoon into the evening.

What’s causing the severe weather?

A Powerful low Stress system with an associated Chilly front is moving across the middle of the United States. Chilly air on its northern side is producing snow and freezing rain for South Dakota, Minnesota and Wisconsin. Meanwhile, on the southern side of the low Stress system, Toasty, moist air is moving north from the Gulf.

As the low Stress gets stronger, a disturbance in the middle and upper levels of the atmosphere will also Shift through. This, Teamed up with a Powerful Chilly front moving into an area that is Toasty and muggy with the flow from the Gulf, will cause the severe weather. The storms are Predicted to develop along the Chilly front through Sunday afternoon and evening.

Continuing severe weather threat

The severe weather threat from this system will Shift east. On Monday, much of the U.S. south, Mid-Atlantic and northeast face a slight Danger (level two out of five) for severe weather. Toasty, moist air remains in place across this area, and a Powerful Chilly front will Form the chance for severe weather as it progresses east.

Monday’s threat will mainly include damaging wind gusts, but isolated tornadoes are possible across the southern U.S. The weather will then likely remain unsettled, and the Storm Prediction Middle has already outlined part of the Ohio Valley for the possibility of severe weather again on Wednesday, April 2nd.

Understanding severe weather outlooks

The Storm Prediction Middle uses a five level Danger category system when forecasting severe weather. The levels are marginal, slight, enhanced, moderate and high.

If your area is outlined in a marginal Danger, Foresee isolated severe storms that are fairly Brief lived. A slight Danger means severe weather is Predicted, but not widespread. An enhanced Danger, which is what millions face today, means more widespread or longer-lasting severe storms are forecast. A moderate Danger means widespread severe weather is likely, with storms that could be long-lived and intense, producing large hail, damaging wind gusts and tornadoes. Finally, a high Danger means long-lasting, very intense and widespread damage from severe weather is Predicted. This would include long-track tornadoes, devastating wind gusts and large hail.

Watches vs. Warnings

During a Danger for severe weather, watches and warnings are issued in order to keep people aware of Threatening weather that could impact them. But do you know the difference between a weather View and a warning?

A View is issued typically hours in advance of impending weather. It means conditions are right for a particular weather hazard to occur, but not that it’s currently occurring.

A weather warning means that particular weather hazard is Predicted to occur soon, or is already happening.

So if a tornado View is issued, this means the weather conditions are right for a tornado to form during a severe thunderstorm. A tornado warning means that a tornado is Predicted to develop, or has already developed and been spotted. During a tornado View you should immediately go to your Danger-Unoccupied Cosmos and wait for the threat to Throw.

Severe Storm Safety

The safest place during a tornado is in a basement or storm shelter. If you don’t have a basement or storm shelter, locate an interior room or closet in the lowest, most central part of your home, away from all outside windows and walls. If you live in an apartment building or high-rise, go to the very bottom floor of your building and again, find an interior room or closet in the Middle of the building away from outside walls and windows.

If you’re driving, find the closest building to take shelter in, but do not take shelter under an overpass. An overpass can act as a wind tunnel and make the winds much stronger, and you will be at Danger of flying debris.

If you live in a mobile home, get out. A mobile home, even with safety straps, cannot withstand winds from the strongest tornadoes and can easily be blown off its foundations. If your mobile home is in a community and has a community Middle, go there to take shelter. Otherwise, find a trusted neighbor, family member of friend that has either a basement or a safer place to shelter and stay there until the threat has passed.

Bottom Line: Millions of Americans are under the threat for severe weather Sunday and Monday as a Powerful Chilly front moves across the middle part of the United States. Damaging wind gusts, large hail and significant tornadoes are all possible.
