A wet start to Saturday across Massachusetts
Rain has once again found its way into the weekend weather forecast for most of Massachusetts, continuing a remarkably wet pattern. This Saturday, May 31, begins with heavy, localized downpours early in the morning. Boston is on track to close May 2025 as one of the five wettest months ever recorded in the city. Currently ranked fifth, it could rise to third place depending on how much precipitation falls today.
Timing and intensity of the rain
Rain is not expected to persist throughout the day. The most active period for precipitation will be between 4 a.m. and 8 a.m.. During these early hours, some cells may bring thunder and result in brief but intense rainfall, potentially causing localized flooding in areas with poor drainage.
After this short but intense burst of rain, the forecast calls for a mix of sun and clouds through the rest of the day. There’s only a minor chance of pop-up showers later in the afternoon, so most of Saturday’s daylight hours should stay dry.
Rainfall distribution and expected totals
The heaviest rainfall totals are expected across central and western Massachusetts, where 1 to 2 inches of rain may accumulate. In Worcester, this marks the 11th consecutive Saturday with measurable rainfall; for Boston, it’s the ninth out of the last 12.
While the rain won’t be prolonged, its intensity and timing might affect morning events. Outdoor sports, including soccer and baseball games, could be impacted by saturated fields and unsafe conditions during or shortly after the early morning rainfall window.
Saturday temperatures and humidity
Despite the wet start, Saturday will feel warm and a bit humid. Afternoon highs are expected to reach near 70°F (21°C), providing a relatively pleasant feel once the rain clears.
If you’re in Boston, Worcester, Springfield, or nearby regions, expect early rain, improving skies, and a warm, humid afternoon—a familiar pattern for a state that’s grown used to soaked Saturdays this spring.
