Cloudy Boston weekend brings scattered Sunday showers before a brief warm-up pushes some towns toward 70s

Clouds dominate the weekend, with a narrow window for rain

Greater Boston is closing out the weekend under persistent cloud cover, with periods of mist, drizzle, and patchy fog limiting temperatures and visibility at times. The most organized chance for precipitation is expected to arrive late Saturday night into Sunday morning, when a passing frontal boundary is forecast to bring scattered showers across eastern Massachusetts.

Rain coverage is expected to be uneven, with the steadiest showers most likely during the early part of Sunday. Conditions should improve later Sunday, with clouds breaking for some afternoon sun in parts of the region. High temperatures Sunday are forecast to reach the mid-50s in Boston, after a cooler, damp-feeling Saturday that remained stuck in the 40s.

Early-week warm-up builds quickly, then turns less certain by midweek

A milder air mass is forecast to settle over southern New England at the start of the workweek. Temperatures are expected to climb into the lower 60s on Monday, with additional warming Tuesday that could push highs into the mid-60s in Boston and even higher inland. Some communities away from the immediate coast may briefly reach the 70s as the warmest air passes through.

By Wednesday, the forecast becomes more changeable again. Cloud cover is expected to increase, and showers may return as another disturbance moves through. The late-week outlook includes cooler air following the midweek system, with temperatures trending back toward the 40s by Friday in Boston.

What to know if you have outdoor plans

• Sunday morning: Plan for wet roads and intermittent showers, especially early in the day.

• Sunday afternoon: Improving conditions are expected, with partial clearing in some areas.

• Monday–Tuesday: The best window for milder, more comfortable conditions, including potential inland highs near 70.

• Wednesday: A renewed chance of showers and thicker clouds.

Forecast confidence is highest for a showery period late Saturday night into early Sunday, followed by a brief early-week warm spell that favors inland locations over the immediate coastline.

Residents should also factor in local variability: coastal neighborhoods often remain cooler during spring warm-ups due to onshore breezes, while interior valleys and suburban corridors can heat up faster when winds turn more southerly ahead of an approaching front.
