Boston, Mass. – Labor Day travelers across Massachusetts will see near-perfect weather, but a sharp cool-down is on the way by midweek. Drivers heading along I-90 and I-93 should expect smooth travel conditions through Monday, with mostly sunny skies and highs in the mid-70s. Still, forecasters warn a surge of September cool air will filter into New England late next week, signaling the first true taste of fall.
According to the National Weather Service in Boston, Sunday and Labor Day will stay warm and bright, with highs near 75 degrees and light winds. Nighttime lows will dip into the mid-50s, a reminder that cooler, drier air is steadily building. By Wednesday, temperatures will climb near 80 during the day but drop quickly after sunset, leaving some suburbs flirting with 50-degree lows.
For families planning outdoor barbecues, picnics, or day trips along Cape Cod, conditions remain favorable through the holiday. No storms are expected, and only light breezes will move across the state. Emergency officials remind residents to stay hydrated during afternoon outdoor events and to watch for slick spots early in the mornings as dew increases on roadways.
Looking beyond the holiday, a national shift in weather patterns will push noticeably cooler air into the Midwest and Northeast starting Thursday. This dip could bring morning lows in the 40s across inland New England by next weekend, a sharp contrast to the sunny warmth of Labor Day.
More updates will follow as September’s cool pattern takes hold.
