Metro Boston, North Shore and metro west: A batch of showers and thunderstorms moved across southern New England overnight and at midday is moving through the south coast, outer Cape Cod and the islands. However, and this has been a trend over the past two months, most of the shower activity slid south of the Boston area with the western half of the Commonwealth and southeastern portions of the state receiving the steadiest and heaviest amounts of rain. Less than a tenth of an inch to just trace amounts of rain fell locally, that is the immediate Boston area, North Shore and metro west, where we needed the rain most. We touched upon this yesterday that the heaviest precipitation would fall to our west and south and that is what happened.
With more disturbances passing just to our south over the next 36 to 48 hours it appears that the bulk of any shower activity is likely to go south of Boston. There is a slight risk for an isolated shower in our forecast area later today, this evening and Wednesday but chances are slim for any beneficial rain, if in fact we get anything at all in northeastern Massachusetts.
The humidity will be around for the next couple of days as well until the last of a series of disturbances takes the last of any showers, clouds and humid air out to sea with it. This will not be until late Thursday and with high pressure building into the area a drier air mass will begin to overspread the region Friday and Saturday.
The weekend starts off nice on Saturday but longer term it looks unsettled for Sunday and Labor Day. It is still early so things can certainly change before we reach the weekend.
