News Summary

New England is experiencing a return of dry air, leading to cool mornings and mild afternoons with temperatures reaching around 70°F. The upcoming week is expected to be mostly dry with filtered sunshine in parts of Massachusetts, particularly in eastern and southeastern regions. A low-pressure system offshore on Wednesday will reduce the chance of rainfall, but light showers may still be possible in southeastern areas. Overall, the conditions are favorable for outdoor activities, but residents should prepare for cool mornings.

Boston — Dry air has returned to New England, bringing cooler mornings with temperatures in the 40s and 50s and afternoon highs near 70 degrees. The week ahead is expected to be mostly dry with mild afternoons, filtered sunshine across parts of eastern and southeastern Massachusetts, and brighter skies north and west of Boston.

Key points

Dry conditions have settled across New England, producing cool starts to the day and mild afternoons.
Morning temperatures are in the 40s and 50s; afternoon highs should climb to around 70°F.
– Filtered or “milky” sunshine is expected across much of eastern and southeastern Massachusetts; thinner clouds will allow brighter skies north and west of Boston.
– A similar weather pattern is expected to repeat on Tuesday.
– A low-pressure system will pass well offshore on Wednesday, lowering the chance of widespread rain but leaving a small chance of light showers in southeastern Massachusetts.
– Sunshine is likely from Thursday through Saturday, with a short warm-up Thursday followed by a drop in temperatures over the weekend.

Current conditions and short-term forecast

Dry air aloft has reduced humidity and helped keep skies relatively clear in many spots. Mornings will be noticeably cooler than recent days, with most inland and coastal locations starting the day in the 40s and 50s. Afternoon highs should reach near 70°F in many communities, offering comfortable conditions for outdoor activities.

The sky will not be uniformly clear: eastern and southeastern parts of Massachusetts can expect a milky appearance to the sky due to diffuse, thin cloud layers that filter the sunshine. Areas north and west of Boston will see thinner cloud cover and generally brighter conditions.

Midweek outlook

A low-pressure system is projected to track well off the New England coastline on Wednesday. Because the center of that system will remain offshore, models show a reduced likelihood of rain for most of the region. However, there remains a small chance of minimal, localized rain reaching parts of southeastern Massachusetts as the system passes.

Tuesday is expected to closely resemble Monday’s pattern, with cool mornings, mild afternoons, and a mix of milky to thinner clouds depending on location. By Thursday through Saturday, the forecast favors more steady sunshine. Thursday may bring somewhat warmer readings, but temperatures are forecasted to fall again heading into the weekend.

Impacts and advice

Conditions are expected to be mainly favorable for travel, outdoor work, and recreational plans through most of the week. Mornings will feel cool, so light layers are recommended. The chance for wet weather is low for the majority of the region, though residents and visitors in southeastern Massachusetts should be aware of the slight possibility of brief light showers around midweek.

Background

Dry air often arrives behind high-pressure ridges and ahead of offshore low-pressure systems. In this case, a drier air mass has reduced moisture at low levels, which keeps fog and heavy cloud cover from forming in many areas. The offshore low-pressure track keeps the bulk of any precipitation away from land, lowering the overall rain chance but not eliminating spotty, coastal rain prospects where the system’s outer bands could reach the shore.

Forecast summary

  • Monday–Tuesday: Cool mornings (40s–50s), mild afternoons (~70°F), milky sun in eastern/southeastern MA, brighter north/west of Boston.
  • Wednesday: Low-pressure system offshore; decreased rain likelihood but small chance of light showers in southeastern Massachusetts.
  • Thursday–Saturday: Mostly sunny; warmer on Thursday, then cooling into the weekend.

FAQ

Will it rain this week?

Widespread rain is unlikely for most of New England this week. A low-pressure system passing well offshore on Wednesday reduces the chance of significant precipitation, though there is a small possibility of light, localized showers reaching southeastern Massachusetts.

How warm will it be?

Mornings will be cool in the 40s and 50s. Afternoon highs will generally reach around 70°F, with Thursday potentially a bit warmer before temperatures drop again over the weekend.

Which areas will see the sunniest weather?

Areas north and west of Boston are expected to have thinner clouds and brighter conditions. Eastern and southeastern Massachusetts will likely see filtered, milky sunshine at times.

Any travel or outdoor impacts to expect?

Most travel and outdoor activities should proceed without weather-related issues. Bring a light jacket for cool mornings, and southeastern coastal areas should be aware of a slight chance for brief, light showers midweek.

When will the sunniest days occur?

Sunshine is expected to be most consistent from Thursday through Saturday.
