Boston, Mass. – Brilliant sunshine and comfortable morning air are giving way to a warmer afternoon across eastern Massachusetts. Streets are dry, visibility is excellent, and it’s an ideal start to the workweek. That quiet stretch won’t last long. A wetter and more unsettled pattern arrives Tuesday night and could affect the Wednesday commute.
According to the National Weather Service, Boston will enjoy mostly sunny skies Monday with a high near 81 degrees and a light southwest breeze developing during the afternoon. Rain is not expected today, allowing outdoor plans, beach trips, and travel to continue without weather-related interruptions.
Tuesday stays warm with a high around 81 degrees. Only a 20% chance of an afternoon shower or thunderstorm is expected before conditions deteriorate Tuesday evening. Rain chances increase to 100% Tuesday night, with showers and thunderstorms becoming likely across eastern Massachusetts.
The wettest period arrives Wednesday. The National Weather Service expects showers likely and scattered thunderstorms, with a 60% chance of rain and temperatures climbing into the middle 80s before clouds and rain become more widespread. Some thunderstorms may produce brief torrential rainfall, gusty winds, frequent lightning, and isolated ponding on roads. While widespread severe weather is not anticipated, a stronger storm cannot be ruled out as a cold front moves through New England.
Drivers using Interstates 90, 93, 95, Route 1, and the Southeast Expressway should be prepared for reduced visibility and slower travel Wednesday, especially during heavier downpours. Travelers flying through Boston Logan International Airport may also encounter weather-related delays if thunderstorms develop near the airport.
Keep outdoor activities flexible for the middle of the week, and monitor updated forecasts if you have travel plans. Sunshine returns Thursday with pleasant summer conditions and highs back near 81 degrees.
