Cloudy skies give way to sunshine Wednesday afternoon as warmer, wetter air moves into New England ahead of a cold front approaching. We expect highs to rise well into the 70s with light winds.
Clouds are rapidly returning to the region Wednesday evening, before our cold front approaches. The lows will fall either side of 60 degrees. A cold front will take quite a bit of energy with it for the first day of fall, bringing gusty showers and thunderstorms for Thursday. Some isolated wind damage cannot be excluded. In the early to mid afternoon, the cold front will sweep east across New England. Temperatures can drop from the mid to upper 70s to the upper 50s in the evening. Southwest winds can blow 25 to 35 miles per hour on the south coast, Cape Cod and the islands.
Hurricane Fiona will approach the island of Bermuda on Thursday, bringing increased swells to the coast. We expect waves over 7 feet offshore and very choppy waves and dangerous rip currents on shore. An unusually cool and windy day is forecast for Friday as the arctic air mass spreads overhead. New England will be sandwiched between the high pressure area coming in from the west and Hurricane Fiona moving to the southeast causing an increased wind field for New England.
The highs will only reach the upper 50s to low 60s during the day. On Saturday, skies are sunny and temperatures moderate to mid to upper 60s in the south, upper 50s to low 60s in the north. The gusty winds may still be there, but they won’t be as strong as they were on Friday. Temperatures will moderate further on Sunday as our next Great Lakes weather system approaches, reaching the mid-upper 70s.
We are expecting a mostly dry weekend apart from the possibility of showers moving into western areas on Sunday. Looking ahead to next week, Monday and Tuesday look wetter than dry, expecting only scattered showers as instability and cold temperatures move overhead. Highs will reach the upper 60s through the mid-70s on the exclusive First Alert Weather 10-day forecast on NBC10 Boston and NECN.
