Boston and the surrounding region is set to experience mostly cloudy skies and temperatures ranging from the low to mid-70s this Tuesday. A slight sea breeze is expected to keep the city a few degrees closer to 70 compared to inland areas.
Foggy spots may appear during the morning hours, accompanied by drizzle or light showers throughout the day. However, the overall trend indicates that it will be drier than wet. Dew points are anticipated to rise slightly, settling around a comfortable 60 degrees.
After enjoying a mostly sunny and pleasant start to the week, the weather pattern will shift slightly as a pocket of high pressure moves offshore. This will bring a southeasterly flow into the area, with an approaching system from the southwest pushing a weak warm front into Southern New England.
What does this transition mean for residents? Expect increased cloud cover along with the possibility of a few showers, particularly in the afternoon. Additionally, some patches of fog could linger on Tuesday morning.
Any rainfall will likely be light and scattered, making it a good idea to take an umbrella if heading out Tuesday morning. During the evening commute, Greater Boston may encounter some sprinkles or light showers.
Weather conditions in the mid-layer of the atmosphere are already beginning to warm, which will contribute to a shift at the surface. As a result, it will feel slightly heavier, with dew points expected to hover around 60 degrees on Tuesday afternoon.
A switch to a southwesterly flow at the ground level will lead to an increase in heat and moisture, particularly starting Wednesday. As the week progresses, temperatures and dew points are projected to rise noticeably.
Looking ahead to Thursday, there is a reasonable chance that temperatures could reach 90 degrees. Until now, Boston has not hit that mark this summer, with the highest recorded temperature being 89 degrees earlier in the month. However, with the potential for 90-degree weather also comes the likelihood of afternoon showers and thunderstorms on Thursday evening, as a front will move through the area in classic mid-summer fashion.
For those taking the day off for Juneteenth, predictions indicate a mix of sun and clouds, with storms likely to develop in the mid-afternoon.
In a reader advisory, it’s still early in the forecast modeling, but there is some optimism regarding the long-term weather outlook. Current models suggest there could be a vast area of high pressure developing in the optimal location to keep Boston entirely dry this weekend.
It will be essential to monitor how the jet stream settles by Wednesday, but the forecast team remains hopeful. While not every region of New England will be completely dry, only a few sprinkles are expected for parts of Western Massachusetts and Vermont.
There is a noteworthy streak to consider: Boston has experienced 13 consecutive Saturdays with measurable rainfall, marking a total of 14 straight weekends. Residents are eager for this trend to conclude this weekend.
The forecast for Greater Boston indicates mostly cloudy conditions accompanied by patchy morning fog and the potential for a sprinkle or light shower. High temperatures are projected to be in the low 70s, with the chance of sprinkles continuing into the night and lows dropping to the mid-60s.
For Southeastern Massachusetts, the outlook is similarly mostly cloudy with a few showers possible throughout the day. Temperatures will hover in the upper 60s near the coastline, and reach around 70 further inland. As night falls, clouds will linger, along with a slight chance of sprinkles and lows in the low 60s.
In Central and Western Massachusetts, the skies will also be mostly cloudy, with the chance for showers both in the morning and afternoon. Expect patchy morning fog, and high temperatures will be in the low to mid-70s, while higher elevations in the Berkshires may remain in the upper 60s. Overnight, temperatures will remain mostly cloudy, with lows in the upper 50s to low 60s.
The Cape and Islands will experience mostly cloudy to overcast weather, with highs in the mid- to upper 60s and some scattered showers possible. Cooler temperatures will persist into the night, with lows around the mid-60s under cloudy cover.
In Rhode Island, anticipate mostly cloudy skies and highs in the low 70s, with temperatures reaching the upper 60s in areas like Newport and Westerly. A chance of sprinkles remains, and the clouds will continue overnight with lows in the low 60s.
New Hampshire is projected to have mostly cloudy skies but with a better chance of sunshine breaking through. Showers will likely be concentrated mainly south of Plymouth, with highs reaching the low 70s, possibly warmer in areas receiving more sunshine. Nighttime temperatures will settle into the lower 60s with mostly cloudy conditions.
In Vermont and Maine, expect partly to mostly cloudy skies and highs in the low to mid-70s, along with the possibility of a shower or two during the day. The night will remain mostly cloudy with the chance of lingering spot showers, leading to lows in the upper 50s and low 60s.
