Boston residents saw a fair weekend, but as the week commences, they're receiving a heads-up for severe weather conditions, according to NBC Boston. This afternoon and evening, the forecast threatens with a round of scattered strong thunderstorms caused by a cold front crossing the region, which could induce damaging wind gusts and potential small hail, the possibility of localized flooding is also a matter to consider given the existing weather circumstances.

While today's high might climb to near 88 degrees complemented by a balmy feel, courtesy of the dew points hovering around 70, there's a less comforting 30% chance of precipitation that might bring about less than a tenth of an inch of rain, however, higher amounts are possible with thunderstorms, according to data from the National Weather Service. This evening, showers and thunderstorms are possible before 10 p.m., followed by a slight chance of showers between 10 and 11 p.m. some storms could produce heavy rainfall, changing the dynamics of the night.

The storms are expected to move quickly, which should mitigate flash flood potential, and as the tumultuous weather clears, Boston is forecasted to embark on a "gorgeous stretch," of weather with highs settling into the comfortable 70s to low 80s, low humidity persists and night temperatures dipping into the somewhat chilly 50s, as articulated by NBC Boston. Monday will manifest sunny with a high near 79 and a northwest wind of 13 to 15 mph.

Midweek is predicted to prolong the pleasant weather; however, by Thursday, this calm front takes a turn as the city gears up for another bout of high temperatures and climbing humidity levels, according to forecasts, by Friday highs could be catapulting into the mid-90s and what follows is an ominous "chance of showers," as described from the National Weather Service, although much of the week seems promising for those favoring a drier spell.
