Starting Sunday, the weather will initially be dry and sunny with highs in the 80s inland and upper 70s along the coast. However, a low-pressure system will develop off the Mid-Atlantic coast, moving north and bringing clouds to the Cape and Islands by noon.
By evening, most of the region will be cloudy, with light rain possibly starting on the Cape around 4 pm, more likely by 8 pm, and spreading to central MA and eastern CT by Monday morning. Winds will shift to easterly, keeping coastal areas cooler, and might gust up to 25 mph around the Cape late Sunday night.
