Rounds of severe weather and torrential downpours will roll from parts of the Midwest to portions of the Atlantic Coast through at least Friday. Expect power outages and travel disruptions.
Floodwaters burst through a basement door at a home in Glassboro, New Jersey, on Aug. 27 after the door began caving under the force of the water, leaving the entire basement submerged.
Parts of the Midwest and the eastern United States will be primed for multiple rounds of thunderstorms capable of severe weather and flash flooding into Friday.
Individual and large complexes of storms will erupt and roll around the northern and eastern edge of a heat dome anchored over the south-central U.S. this week.
The storms may not be confined to the traditional afternoon and evening hours. Some locations can experience multiple storms and multiple episodes of severe weather, ranging from high wind gusts and torrential downpours each day.
Where the storms approach and pass through airport hubs, ground stops, flight delays and cancellations may result. Just north of the thunderstorm zones, there is potential for localized flash flooding each day due to repeated downpours.
