Boston, Massachusetts – A mid-January warm-up could bring periods of rain to much of Massachusetts, while increasing the risk of freezing rain and icy travel conditions inland as temperatures fluctuate near freezing.
According to the National Weather Service Climate Prediction Center, Massachusetts is favored to see above-normal temperatures during the January 9–13 period, with precipitation levels trending near normal. This setup often supports rain along the coast while creating a wintry mix farther inland when shallow cold air remains trapped near the surface.
Interior sections, including Worcester County, the Merrimack Valley, and parts of north-central Massachusetts, may be most susceptible to freezing rain, especially during overnight and early morning hours. Even light icing could lead to slick conditions on I-290, Route 2, and elevated roadways where temperatures tend to run colder.
Along the coast, including Boston, Cape Cod, and the South Shore, precipitation is more likely to fall as rain, limiting snow potential but creating wet roads and reduced visibility during heavier periods. Brief temperature drops at night could still allow isolated icy patches to form.
Travelers are encouraged to stay alert for changing conditions and plan for slower commutes as the pattern develops. Additional advisories may be issued as the period approaches, particularly if colder air presses farther south into the region.
