Boston dwellers can anticipate a weekend that ushers in the essence of fall, complete with cooler temperatures and the chance of scattered showers. A forecast on NOAA's National Weather Service indicates a mostly sunny Saturday with highs approaching 75 degrees and a calm wind turning southeast.

Tonight's conditions will be partly cloudy, with a mild southwest breeze and temps settling around 59 degrees. Sunday brings a slight chance of showers post-noon, peaking with slight chances for thunderstorms later in the afternoon, the daily high hitting near 77 degrees with light winds turning northeast. A report by NBC Boston complements these predictions, hinting at comfortable weather and high temperatures in the low to mid 70s for today and the following day.

Looking ahead, the evening will remain mostly clear with a low around 58 degrees. The new work week greets us with plentiful sunshine and a high near 75 on Monday, as per the National Weather Service. While a weak weather system may bring a few spotty showers to Greater Boston today, a cold front on Sunday could trigger a few isolated showers primarily in southeastern Massachusetts, though Boston residents could see some wet weather as well.

The front's passage by Monday means a dip in high temperatures to the upper 60s and lower 70s, accompanied by, more sunshine. Additional warmth is on the horizon with mid to upper 70s forecasted for Tuesday and Wednesday. "Our average high temperature in Boston this time of the year is 74 degrees," NBC Boston's report provides context. And in a nod to the changing seasons, the first day of fall is slated for September 22 at 2:19 p.m. ET.

Boston's weekend forecast signals an idyllic prelude to autumn, a conclusion evidenced by the collaborative data from NOAA's National Weather Service and NBC Boston.
