We’re tracking gusty winds and a developing coastal storm / Nor'Easter as we head toward the weekend, but today will stay dry. Look for partly sunny skies with breezy conditions and afternoon temperatures in the mid to upper 60s. Along the south shore, keep an eye on the high-tide cycles, where the persistent northeasterly wind could lead to some minor coastal flooding. Keep an eye on the tides and shoreline forecasts through the weekend HERE.

Tonight turns mostly cloudy with lows in the 50s. Winds will remain a factor, with gusts around 25 to 35 mph. Shoreline communities will need to continue watching the high tides, as that persistent northeast wind pushes water toward the coast and could produce additional minor coastal flooding. Thursday is another mainly dry day with partly sunny skies, temperatures in the 60s and wind gusts approaching 35 mph. Minor coastal flooding will remain possible around high tide along the North Shore, South Shore and East End.

The storm gets a little closer Friday, bringing mostly cloudy skies and perhaps a passing shower, but much of the day should remain dry. Highs will stay in the 60s, while northeast winds could gust 30 to 40 mph, especially across the East End.

Conditions begin to deteriorate Saturday as showers become more likely, initially light during the morning before becoming more widespread during the afternoon. Temperatures will remain in the 60s, with northeast winds gusting 30 to 45 mph at times.

The bigger concern this weekend will be along the shoreline. Coastal flooding and beach erosion will be possible around the Saturday and Sunday high-tide cycles as persistent onshore winds continue. Saturday night looks windy with periods of rain and lows in the 50s. Scattered showers and gusty winds continue Sunday, with highs in the 60s. Anyone living along the coast should closely monitor the forecast, especially with several high-tide cycles potentially producing coastal flooding and additional beach erosion. Know your high tide times for today into the weekend.
