Severe storms are possible late tonight through tomorrow morning but there appears to be an even better chance Thursday.

Storms Possible Late
Lows: Around 70
Precipitation: 40%
Severe Storms Likely
Highs: Around 90
Precipitation: 80%
Partly Sunny, Isolated PM Showers
Highs: Low 80s
Precipitation: 30%

Over the next 24 hours, there will be 3 separate opportunities for thunderstorms. First will be during the evening hours as a frontal zone across PA contributes to shower and thunderstorm development. Second… later this evening, an area, a cluster, a segment…whatever you want to call it…of heavy to severe thunderstorms is expected to develop in the Midwest. This area is expected to move steadily to the east/southeast. If it all holds together, heavy rain and thunderstorms could approach the area before sunrise and affect parts of the Thursday morning commute.

Skies will become partly cloudy during the day tomorrow with highs in the upper 80s. It will be very muggy and the atmosphere will become quite unstable. Then during the afternoon, the third opportunity for heavy to severe storms as a cold front crosses the Appalachians and heard towards the I 95 corridor and the Chesapeake Bay. Damaging winds, torrential rain and isolated tornadoes will be possible. Because of recent heavy rain and flooding, the entire area has been placed under a FLASH FLOOD WATCH from 8pm tonight through tomorrow afternoon.
