A late-season cold surge is set to bring below-freezing temperatures and widespread frost risks across Massachusetts over the next week, with the potential for slick travel conditions during early morning hours. The National Weather Service predicts temperatures will run 5 to 15 degrees below seasonal averages, with Boston expected to dip near 32°F and colder inland areas potentially reaching the upper 20s.

Why it matters

This late-season cold snap could pose risks to sensitive plants and vegetation, and create hazardous travel conditions on major roadways like I-90, I-91, and I-495, especially during the early morning commute. The colder pattern is expected to persist through early next week, requiring residents to take precautions.

The details

While precipitation is expected to remain near normal, the colder air will allow for winter-like impacts to develop. Cities including Worcester, Springfield, and Lowell will see widespread frost, especially away from the immediate coastline. In western Massachusetts and higher elevations, light snow showers are possible at times, while central and eastern areas could see brief periods of rain mixing with wet snow or isolated freezing rain on untreated surfaces.

• The cold surge is expected to impact Massachusetts from March 27 through March 31.
• Overnight temperatures in Boston are forecast to fall near 32°F between 2 a.m. and 7 a.m.

What’s next

Residents should protect sensitive plants, cover outdoor vegetation, and allow extra time for the morning commute. Additional weather advisories may be issued as the freezing conditions continue.
