Discussion
It’ll remain very humid today in the Philly metro region and there will again be the chance for PM showers and thunderstorms. Any shower or thunderstorm later today can produce heavy rainfall and localized flooding conditions as they will be slow movers and there is a tremendous amount of available low-level moisture. A cold front will cross the region later tonight and usher in slightly cooler air for the late week; however, it will stall just to our south. As low pressure systems move across the stalled out frontal boundary zone, the chance of showers and thunderstorms will continue in the Mid-Atlantic region through Friday, but at least part of the upcoming weekend looks rather promising.
