Bostonians can anticipate a clear shift in the weather pattern as a cool air mass takes the stage, with temperatures expected to dip this afternoon. The sun will remain a constant companion in the days ahead, but don’t let the bright skies fool you—the mercury is sliding due to a persistent northeast wind ushering in a change of season, as detailed by NBC Boston.

Along the coast, gusts could ramp up to near 40 mph, particularly around Cape Cod and the Islands, as a result of an incoming high-pressure system. Despite the substantial sunlight, the cool breath of the northeast wind beginning its descent Tuesday afternoon, will chill things down through Wednesday, according to the National Weather Service. Riders can expect the winds to speed up the chill setting in with gusto.

As distant tropical storms Humberto and Imelda continue to churn far from New England's shores, their influence will nonetheless be felt in the form of heightened surf and rip currents beginning Tuesday and continuing through late in the week, as reported NBC Boston. These conditions could lead to beach erosion and render coastal waters more treacherous than one might wish.

Despite an active atmosphere, the high-pressure system thats arrives will bring a reprieve from the blustery weather. Thursday is pegged to be the week's coolest day, struggling to hit the 60-degree mark along the coastline. But by Friday and into the weekend, temperatures will experience a swift rebound, with highs potentially soaring back into the 80s starting Sunday, as NBC Boston noted.

September wraps up drier than usual for the city of Boston, closing nearly a half inch below normal in terms of rainfall, signifies the fourth consecutive month and one of ten in the past year to log below average precipitation. With Bostonians looking forward, the question remains whether the drier pattern will persist into October.
