Boston, Massachusetts – Arctic air is expected to remain entrenched across Massachusetts from Jan. 24 through Jan. 30, bringing a prolonged stretch of below-normal temperatures and reinforcing mid-winter conditions across the state.
According to the National Weather Service Climate Prediction Center, Massachusetts falls within a 60 to 70 percent probability zone for below-normal temperatures during the Jan. 24–30 period. While not as extreme as northern New England, confidence remains solid that cold air will dominate with limited opportunities for sustained warming before the end of the month.
Across western and central Massachusetts, including the Berkshires and the Worcester Hills, daytime highs are expected to run well below seasonal averages, with overnight lows frequently dropping into the single digits and teens. Persistent cold will allow snow and ice to linger on roads such as Interstate 90, Route 2, and secondary highways, especially in shaded and elevated areas.
In eastern Massachusetts, including the Boston metro area and the Interstate 95 corridor, temperatures are also expected to stay below normal throughout the Jan. 24–30 window. Even during brief moderation periods, highs may struggle to climb out of the 20s, increasing the risk for icy patches on bridges, overpasses, and untreated sidewalks.
Massachusetts emergency management officials encourage residents to take cold-weather precautions, including protecting exposed pipes, limiting prolonged outdoor exposure, and checking on vulnerable neighbors, seniors, and pets.
The Arctic pattern shows little indication of breaking before the calendar turns, and additional cold-related advisories may be issued as confidence remains elevated in sustained below-normal temperatures across Massachusetts through Jan. 30.
