At least 80 million people — from the Midwest to the South to the East — are in the path of turbulent weather, including violent storms, large hail, and potent tornadoes Sunday into Monday, forecasters said.

“Numerous severe thunderstorms are expected today and tonight across a broad portion of the Southeast and lower/mid Mississippi Valley into the Ohio Valley and southern Great Lakes,” NOAA’s Storm Prediction Center said Sunday. Destructive winds were “likely,” the center added. “Several tornadoes will also occur with supercells. A few of these tornadoes could be strong.”

Accuweather meteorologists warned that more than a dozen tornadoes were possible Sunday afternoon and Sunday night, targeting cities such as Little Rock, Arkansas; Memphis and Nashville, Tennessee; Paducah, Kentucky; Evansville and Bloomington, Indiana.

Some of the areas in the crosshairs this week are the same ones lashed by a series of tornadoes and storms two weeks ago that left more than 40 people dead. Over a two-day tornado outbreak, the National Weather Service issued more than 300 storm warnings. Three tornadoes were confirmed as EF4 strength, according to AccuWeather.

Three EF3 tornadoes were also surveyed in Alabama, Arkansas, and Missouri.

Possible golf ball-sized hail and powerful winds

Storms that could drop golf ball-sized hail and bring wind gusts topping 70 mph were possible Sunday night into Monday morning for the middle of Tennessee, the weather service also warned.

Meanwhile, the Louisville metro area is under an “enhanced risk” for severe weather, the third-highest of five categories issued by the National Weather Service’s Storm Prediction Center. A line of storms will reach southern Indiana as early as 5 p.m., then arrive in Louisville Sunday night, starting around 8 or 9 p.m., NWS Louisville meteorologist Tom Reaugh said during a conference call Sunday afternoon.

The storms may take one to three hours to pass through.

“Over the last few days, (the severe storms) were looking like a nighttime event, but as the event draws closer and new model data comes in, it looks like it’s trending earlier and earlier,” Reaugh said.

Strong winds swirling Sunday

A wind gust of 85 mph that led to damaged roofs and downed trees was recorded in Baxter Springs, Kansas, early Sunday, Weather.com reported. In Joplin, Missouri, a gust of 79 mph was measured, and hail up to 2.5 inches in diameter fell near Bridge Creek and Amber, Oklahoma, the service said.

Meanwhile, strong winds and heavy rain across the South Bend, Indiana, region left a trail of destruction, downing multiple trees, powerlines and causing severe damage to multiple structures. No injuries have been reported, as a tornado watch that the National Weather Service issued early in the day expired just after 6 p.m. local time.

More than 450,000 power outages were reported across Indiana, Michigan, and Wisconsin on Sunday evening. Snow and freezing rain snapped power lines and downed trees, making some roads impassable in the states.

Where will the storms head Monday?

The storms were expected to target the Southeast, Mid-Atlantic and Northeast by Monday from Jacksonville, Florida, to Raleigh, North Carolina, to Albany, New York, according to forecasters.

“Monday’s severe weather will affect the very busy Interstate 81, 85 and 95 corridors from New Orleans to Atlanta, Charlotte, Washington, D.C., Philadelphia, and New York City,” Accuweather said. 

Monday’s highest risk of tornadoes covered an area from southern Alabama into Virginia, Weather.com said.

What is the forecast for the rest of the week?

The tumultuous weather shows no signs of calming down: More strong storms could stretch from the Central U.S. to the East Coast midweek, forecasters said.

“As the spring weather pattern continues with a tug-of-war between warm and humid air from the Gulf and chilly winds from Canada, additional rounds of severe weather will follow,” Accuweather said.
