Some places get beneficial rain, and some places get localized flooding in a situation like this. Heavy showers and thunderstorms which developed over western New England during the day Saturday have moved slowly eastward and finally made it into parts of eastern New England (still yet to cross parts of RI and southeastern MA as of 6PM). The leading edge of this zone, especially south of the Mass Pike, has the heaviest thunderstorm activity, and the slow-moving nature of these storms is resulting in some flash flooding. This will continue to move across RI and portions of MA especially south of the Mass Pike during the first couple hours of Saturday evening, with mostly moderate to occasionally heavy but more beneficial rain to the north. Later tonight, activity will subside. However, with low pressure riding along a front just to the south, expect clouds and occasional showers to last through Sunday.
Monday & Tuesday will bring a break as a small area of high pressure builds in.
Starting Wednesday, tropical moisture will make a comeback and stay for at least a few days, bringing humid weather and daily shower and thunderstorm threats.
