A coastal low exits midweek, leaving behind a stretch of dry, comfortable weather. Cooler air filters in on Friday. High pressure dominates through Saturday with sunshine and seasonable temperatures. By Sunday, a weak disturbance may bring some clouds and a stray shower, but most of the period remains dry. Highs stay in the low to mid-70s with crisp nights in the 50s, and another bright stretch continues into the middle and latter part of next week.
The second week of August brings a near-perfect start, with sunshine, low humidity, and comfortable nights through Saturday. But by Sunday, the heat makes a strong return. A stretch of hot and increasingly humid days settles in through midweek, with widespread 90s and sticky conditions. Most of the week remains dry, but a few pop-up storms are possible later next week as the pattern turns more unsettled. Friday, August 8 – Sunny and warm
A beautiful summer day.
The end of July brings a major flip in the weather. After weeks of summer heat, clouds and a cool northeast breeze move in Thursday into Friday, and with it, the potential for a soaking rain. Some neighborhoods could pick up heavy totals, and if the rain bands line up just right, the National Weather Service may hoist flood watches for parts of southern New England Thursday night into Friday. The weekend turns gorgeous, sunny, dry, and comfortable, before warmth and humidity slowly return next week, setting up a more classic August pattern by late week. Friday, August 1 – Much cooler with periods of rain
A dramatic change, raw, damp, and nearly 20 degrees cooler than earlier this week.

A thunderstorm rolled through Watertown Friday afternoon, and two lightning bolts struck around town. The severe thunderstorm storm hit the City around 2:30 p.m. and lightning bolts struck in two spots, according to the map on LightningMaps.org, at:
• The Common Street Cemetery (near Watertown High School). • Near Orchard Street in the vicinity of Victory Field
The storm left damage, including a downed tree on Grant Avenue, Channel 7 reported. Wicked weather in Watertown on Grant St creating quite the mess…leaving this Tesla buried under downed trees when today’s summer scorcher turned into wild winds and drenching downpours without much warning #7News pic.twitter.com/bjZNzihc9n— Steve Cooper (@scooperon7) July 25, 2025
There were also strikes near Watertown:
• In Belmont off of Lexington Street (north of Belmont Street)
• In Newton, south of the Charles River near California Street, west of Bridge Street.
A significant warmup peaks Friday with heat and humidity combining for oppressive conditions — possibly the last true high heat of the season. A cold front arrives late Friday, bringing storm chances and a modest cooldown for the weekend. Saturday and Sunday are seasonable, though humidity lingers and scattered showers may return late Sunday. Early next week offers a brief stretch of pleasant weather, but another warm and muggy surge arrives midweek with renewed storm chances. Long-range signals suggest the start of August could trend cooler than normal, perhaps our first real hint that summer is slowly beginning to wind down.
After one final burst of heat and humidity on Thursday, a cold front ushers in a more comfortable and seasonable pattern. Friday and Saturday look beautiful with sunshine, drier air, and lower dew points. A brief uptick in humidity returns Sunday with clouds and the chance for scattered showers. Early next week features pleasant summer weather with sunshine and average July temperatures. By mid to late week, warmth and humidity slowly build again, with a few chances for afternoon storms as another front approaches.
A bit of a weather rollercoaster sets up across the area this week. After a day of local heavy downpours on Thursday, a slow-moving front lingers nearby. Conditions gradually improve by the weekend, with dry weather, brightening skies, and seasonable warmth. Then, from Monday through midweek, summer arrives in full force. A southwest flow brings rising temperatures and muggy air, with highs soaring into the upper 80s and low 90s.
The upcoming stretch features a classic run of summer weather. After a hot, stormy start to the week, a cold front clears the region just in time for Independence Day, ushering in drier and more comfortable air. High pressure then dominates much of the holiday weekend, keeping skies mostly sunny and humidity at bay. Another warm-up arrives by Sunday into Monday, with 90°F possible again and a slight uptick in storm chances. While a few showers may pop up later in the week, widespread rain looks unlikely.
Relief is here. A backdoor cold front has swept through the region, dropping temperatures and humidity dramatically across Eastern Massachusetts. The transition from oppressive to refreshing is already underway, with highs in the 70s for several days. Expect low clouds, onshore breezes, and occasional showers as cooler marine air dominates. Heading into next week, the pattern flips again as warming resumes by Sunday with 80s returning, and the potential for thunderstorms increases.
