Forecast discussion: Despite bright sunshine through most of Sunday, Boston still had to deal with gusty winds and some strong thunderstorms over places like New Bedford and Plymouth. This was due to a low pressure system that passed over Southern New England, along with an area of high pressure trying to move east. The combination of the two systems meeting is what created the strong winds, and the low helped create the thunderstorms.
As we move into this evening, we will still feel some occasional gusty winds, as the low moves out, and high pressure continues to build over the area. However, we will remain dry for the next few days. Except for a widely isolated shower during the afternoon, we will see at least partly sunny skies. Temperatures during the daytime will remain seasonable, and low temperatures will be slightly below normal. The high will continue to give us dry weather into Wednesday night.
As we head into early Thursday morning, a frontal boundary from North Carolina straight west to eastern Kansas will slowly move north. This front will move northward and bring scattered showers and even an isolated thunderstorm during Thursday. According to the models, the shower activity will continue well into Friday, but we will see a lull in the precipitation by late Friday afternoon. But, the models agree that a new shield of precipitation will arrive over the area by early Saturday morning. We will see more showers and possible thunderstorms into Sunday morning. Skies will begin to clear by Sunday afternoon, as the cold front associated with the low moves offshore. High pressure ridging will build into New England. Temperatures will actually be slightly above normal for the weekend.
