Showers move in this afternoon and spread from west to east as an area of low-pressure approaches from the Ohio River Valley. It rides along a stationary front placed south of Nantucket. Heavy rain will fall near the center of the area of low pressure, mostly along the South Coast, Cape Cod and Islands into Saturday morning.
Tonight, high astronomical tides and a storm surge around one-half foot may result in some minor splashover over the typical spots near the coast during high tide. The wind will also ramp up tonight with gusts up to 45 mph possible across Nantucket and Martha’s Vineyard. Mariners will need to be careful as the waves will continue to build this weekend.
