Hartford, Connecticut – St. Patrick’s Day week across Connecticut could bring a late reminder that winter is not finished yet, as colder Canadian air increases the chance for late-season snow just days before the first day of spring.
According to the NOAA Climate Prediction Center’s 8–14 day outlook, the period from March 15 through March 21 favors above-normal precipitation across New England and parts of the Northeast, while temperatures across much of the eastern United States trend below seasonal averages. The pattern forms as a broad cold boundary drops south from Canada, stretching from northern New England across the Great Lakes and down toward Georgia and northern Florida.
For Connecticut, that setup places Hartford, New Haven, Bridgeport, Stamford, and New London in a corridor where storm systems tracking along the East Coast could interact with colder air, increasing the potential for late-season snow or rain-to-snow transitions during St. Patrick’s Day week.
Drivers along Interstate 84, Interstate 91, Interstate 95, and the Merritt Parkway should monitor conditions closely if storms develop. Even modest late-season systems can create slick roads and reduced visibility during overnight hours and the morning commute.
The outlook stands out because daylight saving time begins this weekend, yet winterlike conditions may linger across the Northeast even as the first day of spring arrives later that week.
Forecasters expect the pattern to evolve over the coming days, and additional advisories could follow if storm systems align with the colder air mass across southern New England.
