The Boston region will endure one more warm, muggy day on Saturday before cooler, drier air arrives.
Forecasters expect the morning to be partly to mostly cloudy with a few leftover showers exiting Cape Cod, Martha’s Vineyard, and Nantucket. Highs will reach the 80s in many areas, and humidity will be high. Showers and thunderstorms are possible, especially during the afternoon.
Much cooler, drier air moves in Saturday evening ahead of a very comfortable day on Sunday.
