Boston, Massachusetts — Bitterly cold conditions will persist across eastern Massachusetts through Saturday, with dangerous wind chills impacting travel and outdoor safety along Interstate 93, I-90, and surrounding roadways.
According to the National Weather Service in Boston, dry weather will continue through the end of the week, but temperatures will remain well below normal. The coldest period is expected Thursday night through Friday night, when wind chills could drop as low as 20 to 25 degrees below zero in some locations.
Forecast data shows overnight and early morning hours will pose the greatest risk, with the lowest apparent temperatures expected Thursday night into Friday morning and again Friday night into early Saturday. Even coastal areas may experience dangerously low wind chills during peak cold periods.
While no significant snowfall is expected, travel impacts may still develop due to extreme cold. Pavement temperatures will remain very low, allowing any moisture to freeze quickly and creating slick spots on bridges, overpasses, and elevated roadways along I-93, I-90, I-95, and Route 128. Vehicle issues, including reduced battery performance, are also more likely in prolonged cold.
The National Weather Service warns that frostbite can occur on exposed skin in as little as 30 minutes or less under these conditions. Residents are urged to limit time outdoors, dress in layers, cover exposed skin, and bring pets indoors.
Homeowners are advised to protect pipes from freezing and check heating systems, while drivers should ensure vehicles are winter-ready and carry emergency supplies.
Although conditions remain harsh through Saturday, forecasters note that temperatures will gradually moderate afterward. Until then, the emphasis remains on cold-weather safety rather than snow-related impacts.
Students, early-morning commuters, and overnight workers traveling along major corridors should prepare for extreme cold exposure and plan extra time for cold starts through the end of the week.
