Bostonians are savoring what could be the final glimpses of summer as temperatures persist in the 80s, with Monday expected to reach a high of 83 degrees. While the city might not hit the record highs of 86 degrees set in years past, locals will nonetheless bask in the warmth before a cooler shift takes hold. At night, the skies remain clear as the mercury dips to around 60, according to the National Weather Service.

However, this warm spell won't linger long, "summer keeps rolling! We've got another day in the 80s ahead on Monday,” NBC Boston reports, and by Tuesday, the National Weather Service forecasts a modest decrease in heat that would still yield a high near 80, as a mostly sunny sky graces Boston this constitutes our last day of such high temperatures as the region braces for the impending rain. The onset of showers is likely Tuesday night, with the chance of precipitation climbing to 60%.

Wednesday's forecast guarantees a wetter outlook with a 90% chance of showers before 4pm and the high hovering around 68 degrees, as reported by the National Weather Service. The showers may continue intermittently through Wednesday night, with a 30% chance early on, though skies will clear by Thursday, introducing significantly cooler air that will pull temperatures down to the upper 50s, despite sunny conditions.

The shift towards colder weather comes complete with the likely occurrence of a hard killing freeze on Friday morning, though downtown Boston may dodge the bullet, the countryside isn't as lucky, NBC Boston warns, the next opportunity for substantial rainfall might come with a developing coastal storm late in the week, projections show it could bring a windswept rain into New England as early as late Sunday and carry on until early Tuesday, yet at this point the extent and impact of the wet weather remain unclear.
