Storms will continue to track through the Eastern United States to end the week, with some storms lingering into the weekend as frontal boundary and low pressure system move through. Isolated severe storms are possible, along with heavy rainfall rates that could lead to flash flooding.
A low that moved through the Northeast on Wednesday will drag a frontal boundary through the Ohio Valley and Mid-Atlantic through Thursday night. Scattered thunderstorms are expected, with isolated severe storms possible. Wind and hail damage will be the main hazards.

Storms have already produced flash flooding early Thursday, with another round expected through the afternoon and evening. The strongest storms are mostly expected during the day, but overnight convection could still create issues.
Scattered flash flooding is possible from Kentucky into West Virginia (dark green area below), while isolated flash flooding is possible east through southern New Jersey.

The low pressure system dropping through the Plains Thursday will kick east Friday into Saturday, bringing another round of rain and storms. Storms look to target the Southeast and Mid-South on Friday with strong storms and heavy rain. These storms will lift to the northeast on Saturday, brining heavy rain back to Ohio and Pennsylvania, while storms will continue to move through the South.
Rainfall totals look impressive where several rounds of rain are possible. Some regions could see 2-3 inches widespread, with 4-5 inch totals possible in smaller areas.

This rain will be coming down quickly, increasing the chance for isolated flash flooding. A large section of the east will have the chance for flooding Friday into Saturday (below).
