On the heels of Saturday's outbreak, the risk of damaging thunderstorms will continue through the Memorial Day weekend with communities from Michigan to Texas being threatened into Sunday night.

The severe weather danger Sunday will not be as high when compared to Saturday’s outbreak, but thunderstorms capable of causing damage and endangering residents and holiday visitors will still erupt.

The area at greatest risk stretches from central Michigan and western Pennsylvania to central Texas. A second area will unfold in the vicinity of North Carolina, threatening to interfere with the Coca-Cola 600 at Charlotte Motor Speedway.

Much to the relief of residents cleaning up from Saturday's outbreak, the majority of the severe thunderstorms will bypass the Tennessee Valley.

Cities in the threat zone include Detroit; Pittsburgh; Columbus and Cincinnati, Ohio; Louisville, Kentucky; Raleigh, North Carolina; Shreveport, Louisiana; and San Antonio and Austin, Texas.

A severe thunderstorm may also endanger fans at the Indianapolis Motor Speedway.

“Barbecues might get postponed a little bit as thunderstorms rumble,” AccuWeather Storm Warning Meteorologist Richard Schraeger said.

“The primary concern with these redeveloping storms will be damaging winds, large hail, local flash flooding and a few isolated tornadoes.”

Sunday’s severe weather is not expected to produce a widespread swath of damaging winds or the destructive hail that residents in the central United States experienced Saturday.

However, it only takes one damaging thunderstorm or tornado to devastate a family or community.

The thunderstorms are expected to evolve into potentially flooding rain in the central Appalachians into Sunday night. The soaking rain will spread to New England on Memorial Day.

Thunderstorms capable of causing flooding and strong wind gusts may still be ongoing along the western Gulf Coast to start Memorial Day with additional thunderstorms to follow across the South as the day progresses.

The severe weather threat will continue to lessen from its peak on Saturday, but an isolated risk will still be present.

“The strongest thunderstorms will be capable of producing damaging wind gusts, large hail and local flash flooding," Schraeger said.

More of the thunderstorms will prove disruptive to picnics, parades and other outdoor holiday festivities.

Regardless of a thunderstorm’s severity, the risk of being struck by lightning is present as soon as thunder is heard. Residents should monitor AccuWeather MinuteCast® and prepare to seek shelter for a time.

Remember that a pavilion is not a safe place to be during a thunderstorm. Moving inside a vehicle would be a better option.

“The threat for tornadoes across this region will be fairly low on Monday,” Schraeger said. “But, a few weak and isolated tornadoes are possible during the early to midafternoon.”

As the sun sets on the holiday weekend, any severe thunderstorms will also begin to fizzle.
