Boston residents can expect a week of muggy weather and intermittent storms, with patches of fog rolling in as a tepid appetizer to the forthcoming sultriness. According to the National Weather Service forecast, early fog today will dissipate, giving way to mostly sunny skies and a high of 81 degrees. Light easterly winds will accompany the moderate temperatures. Come nighttime, the fog will sneak back into the city, with clouds increasing and temperatures dipping to a low around 68.

For those looking forward to spending their Sunday on Boston's slices of shore, the fog will clear by late morning, paving the way for improved conditions with humidity making itself comfortable in the upcoming days. Despite the subtle dance of the fog and modest rain chance later in the weekend, "winds stay light and seas remain calm," as observed by a report on NBC Boston.

Monday brings potential for atmospheric drama, with a slight chance of showers in the morning and the possibility of showers and thunderstorms post-3pm. The high for the day is anticipated to reach an agreeable 86 degrees, as per the National Weather Service. As the humidity grips the region tighter, each day will challenge the one before it in terms of heat, with Tuesday and Wednesday's highs nearly touching the 90s.

Midweek is marked not just by scorching heat but also a stickiness that will make the air heavy, and "by Thursday into Friday, the pattern becomes more unsettled again," paving the way for potential storms, "with a cold front moves in," bringing a better shot at showers and thunderstorms to end the week, reports NBC Boston. Thursday promises a prelude to the precipitation with thunderstorms likely after 4pm and a high near 89.

Friday continues with the chance of showers. True to New England unpredictability, the weather will vacillate between partly sunny and hot conditions and the prospects of rainfall. Locals who have been braving the increasing heat will find solace in Saturday's forecast, which promises mostly sunny skies with a high closer to 83 degrees – a brief respite before the cycle begins anew.
