A stalled front lifting north will trigger rounds of thunderstorms across Delmarva starting Monday and lasting into Tuesday night. With temperatures climbing into the upper 80s to low 90s and abundant moisture, the atmosphere will become increasingly unstable. Forecast models point to a heightened risk of damaging wind gusts and localized flash flooding, especially Tuesday, when a Slight Risk for severe weather has been issued. Quieter and more pleasant weather is expected to settle in by midweek and continue through the Fourth of July holiday weekend.
