In preparation of the incoming winter storm, the City of Watertown would like to share a few key updates to the community. The City of Watertown will not be declaring a snow emergency due the incoming snow fall happening on January 18, 2026.
After warm front late Thursday night into Friday brings a brief chance of showers, expect a warm and humid stretch Friday into Saturday. Scattered thunderstorms, a few possibly strong, may develop Saturday afternoon and evening with a passing cold front. Behind it, cooler and drier weather settles in Sunday through much of next week, with crisp mornings and comfortable afternoons. Highs return to the low/mid-70s with lows dipping into the 40s and 50s early next week, before moderating slightly again by midweek. Friday, September 5 – Morning showers, then warm & humid
A few showers linger early, then skies turn mostly sunny.
A frontal system brings one last chance of showers and storms Friday, followed by a stretch of dry, beautiful weather through the holiday weekend and into next week. Temperatures run slightly below average at first, with crisp mornings and comfortably warm afternoons, then gradually trend back toward the low 80s by midweek. Humidity stays moderate to low, making for a very pleasant start to September. Friday, August 29 – Showers and storms, then clearing
A cold front moves through the region. The morning begins partly sunny, but showers develop mid- to late morning, with embedded thunderstorms possible by midday into early afternoon.
Cooler than normal, low-humidity conditions continue through midweek before temperatures rebound into the weekend. A midweek storm system brings widespread rain, then Hurricane Erin passes well southeast of New England on Friday, producing no direct impacts inland but stirring up rough surf, rip currents, and gusty winds across Cape Cod and the Islands. For most of Eastern Massachusetts, the pattern turns warmer and drier over the weekend. Another front brings a chance of showers late Sunday into Monday, followed by a return to seasonable and pleasant late summer weather midweek. Friday, August 22 – Mostly sunny inland, windy for the Cape and Islands
Hurricane Erin passes far offshore, too distant for direct rain or wind inland.
After showers and thunderstorms on Thursday as a cold front pushed through, cooler, less humid air moves in for Friday and Saturday under high pressure. Heat and humidity return briefly Sunday before another front brings showers and storms late Sunday into Monday. Early next week trends cooler and drier, with pleasant late-summer weather lasting into midweek. Signs of fall weather are starting to show, and the last throws of summer may be here this week. Saturday, August 16 – Warm and dryStill sunny with low humidity.
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.
