The remnant low of Barry (currently a tropical depression) will continue to weaken and gradually track northeast into the Ohio Valley/Great Lakes toward the middle of the week. Heavy rain & flash flooding swamping the Mississippi River valley will shift northeast as well.
Our best chance for widespread showers, storms & heavy rain hits Tuesday night into Wednesday and rapidly diminishes later in the week as high pressure takes over. Expect 1" to 3" across the Commonwealth. Highs will fall from the mid to upper 80s Monday to upper 70s Wednesday and back into 90s Friday into the weekend.
