Bostonians can expect a weekend of decent weather with only a slight chance of showers, according to the National Weather Service. Today's forecast promises partly sunny skies with temperatures hovering near 80 degrees, while a calm wind from the east at 5 to 8 mph is expected to set in by the morning. As night falls, the city may see patchy fog after 11 pm and an uptick in cloud cover, cooling off to around 65 degrees.

The picture for Sunday looks similar: "Patchy fog before 9am. Otherwise, cloudy, then gradually becoming mostly sunny," with highs again around 80 degrees and a light breeze shifting from the southeast to the east, up to 9 mph. Those in central and western Massachusetts, however, "have a slightly greater chance in the afternoon as humidity works with the unstable air to fire off a few downpours - or in the case in western Mass., a few storms," as NBC Boston reports.

The upcoming workweek signals a turn towards hotter temperatures, beginning with Monday, as possibilities of showers and thunderstorms arise after 2 pm with a 30% chance of precipitation and highs reaching up to 86 degrees. Moving into Tuesday, Bostonians will experience mostly sunny skies and hot conditions, with temperatures climbing near 91 degrees and light winds around 6 mph.

Forecasts indicate that while the weekend may bring isolated downpours in some areas, overall conditions are expected to remain favorable. However, a warming trend is set to begin midweek, with high temperatures projected to reach the low 90s on both Wednesday and Thursday. According to meteorologists, Thursday night also carries a 30% chance of showers. Increasing humidity and cloud coverage are anticipated as the week progresses, with the possibility of a brief heat wave developing. Coastal areas may benefit from cooler breezes, while inland regions face a higher chance of rainfall.
