Boston, Massachusetts – Bright sunshine is lighting up Boston late Sunday morning, but a noticeable weather shift is already taking shape just beyond New England. Dry pavement, blue skies, and comfortable temperatures are providing ideal conditions today, yet meteorologists are tracking a wetter pattern that could affect travel and outdoor plans by Monday afternoon and Monday night.
According to the National Weather Service, Boston will climb to around 83 degrees Sunday under mostly sunny skies. A brief shower or thunderstorm cannot be completely ruled out late in the day, but most neighborhoods across eastern Massachusetts should remain dry through the evening.
The bigger weather story arrives Monday. Showers become increasingly likely after 2 p.m., with rain coverage expanding across Suffolk, Middlesex, Norfolk, Essex, and Plymouth counties. Rain chances increase from 60% during the day to 90% Monday night.
Drivers along I-93, I-95, Route 128, the Massachusetts Turnpike, and the Southeast Expressway should prepare for changing conditions Monday afternoon. Wet roads and reduced visibility could slow traffic during the evening commute. Plan extra travel time if heading into downtown Boston or toward Logan International Airport.
For now, conditions remain favorable for beaches, parks, and outdoor events. Temperatures hold near 79 Monday despite increasing clouds and developing showers. The unsettled stretch appears relatively brief.
By Tuesday, improving conditions return with partial sunshine and highs near 82 degrees. Wednesday looks even better, featuring sunny skies and temperatures reaching the mid-80s across much of eastern Massachusetts.
Long-range outlooks suggest above-normal temperatures may continue into late June, supporting an early taste of summer across southern New England.
Additional severe weather concerns remain limited at this time, though isolated thunderstorms could accompany Monday’s rain. Residents should monitor future updates as timing becomes more refined.
