Here’s the updated daily weather forecast by Meteorologist Matthew Moll of New England Weather Consulting:

Weather Outlook: July 31 to Aug 8, 2025

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.

Thursday, July 31 – Clouds increase, turning unsettled
A break from the recent heat, but it stays sticky. Expect plenty of clouds with some breaks of sun. A few showers or a stray thunderstorm could move in later, setting the stage for steadier rain Thursday night.

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.

Here’s the updated daily weather forecast by Meteorologist Matthew Moll of New England Weather Consulting:

Weather Outlook: July 10 to July 18

A bit of a weather rollercoaster sets up across the area this week. The forecast begins with clouds, fog, and locally heavy downpours as 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. A few scattered afternoon thunderstorms are possible, but most days will be dominated by heat, humidity, and hazy sunshine.

Thursday, July 10 – Damp, humid, and potentially soaking
A slow-moving front hangs over southern New England, keeping skies cloudy and the air sticky. Showers and embedded downpours are likely, especially late morning into early afternoon. The Weather Prediction Center has placed the region in a marginal risk for excessive rainfall. Localized flooding in poor drainage areas is something to watch for.
• High: 73 to 75°F | Low: 63 to 65°F | Wind: East at 5 to 8 mph
• Sky: Cloudy with patchy fog and periods of showers or heavy rain
• Chance of rain: 80%

Here’s the updated daily weather forecast from Thursday, June 26th to Friday, July 4th by Meteorologist Matthew Moll of New England Weather Consulting:

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. The first days of July may flirt with summer heat again.

Looking ahead to Independence Day, an early read suggests warm and mostly sunny weather for July 4 across Eastern Massachusetts, great for outdoor plans. However, as of this writing it’s still several days out, so we will keep you posted if there are any significant changes.

Thursday, June 26
